Learn how pollution affects exercise performance and health—and how to adjust workouts when air indoor and outdoor air quality shifts.

","content","Most of us exercise to strengthen our bodies and minds, yet the air we breathe during a workout is often overlooked. Air quality can significantly affect both exercise performance and overall health, particularly during high-intensity or prolonged workouts. As breathing rate increases, exposure to airborne pollutants increases along with it. In enclosed spaces like gyms and studios, poor ventilation can allow pollutants to build up, potentially undermining the benefits of physical activity. With the right awareness and a few practical adjustments, it’s possible to protect your lungs and get more out of every workout. Here’s how air quality affects exercise—and what to do about it. How air quality impacts your workout When you exercise, your breathing deepens and quickens. While this flood of oxygen fuels your muscles, it also means you’re inhaling more of whatever else is in the air: dust, mold, volatile organic compounds (VOCs) from cleaning products, and even PM2.5 —tiny particulate matter measuring less than 2.5 microns in diameter—can enter your lungs and circulate throughout the body. Studies confirm that indoor air pollution levels in gyms often surpass WHO safety limits (1). During a high-intensity workout, you might inhale 90 liters of air per minute or more, compared to just 6 liters at rest (2). That’s 18 times more pollutants entering your lungs and bloodstream—where they can trigger inflammation and limit oxygen delivery to working muscles. Both PM2.5 and gases like carbon dioxide (CO2) accumulate quickly in enclosed spaces. These irritants inflame airways, making it harder to breathe deeply and efficiently. Over time, this can lead to chronic oxidative stress, weakening lung function and endurance. A 2018 study found that gyms in Brazil, France, and other areas of Europe had CO2 levels exceeding 1,000 ppm, a threshold linked to cognitive decline and fatigue (3). Poor ventilation was the primary contributor. Indoor air can harbor two to five times more pollutants than outdoor air, according to the U.S. EPA (4). Why indoor air quality matters during exercise It’s easy to assume that indoor workout spaces are inherently cleaner than the air outdoors. In reality, indoor air quality can vary widely depending on ventilation, occupancy, and cleaning practices. During exercise, deeper and faster breathing increases exposure to airborne pollutants—even when they’re present at levels that might go unnoticed at rest. A gym that looks clean or smells fresh may still contain elevated levels of particulate matter or carbon dioxide, particularly during busy classes or peak hours. This doesn’t mean indoor exercise is unsafe—it means air quality plays a larger role in workouts than many people realize, and that managing ventilation and filtration can make a meaningful difference. Health risks of exercising in polluted air The effects of poor air quality are measurable, both immediately and over time. Fatigue and reduced performance: Exposure to PM2.5 has been found to increase fatigue, affecting athletic performance (5). Respiratory issues: Regular exposure to air pollutants is linked to asthma-like symptoms and decreased lung capacity, even in healthy individuals, due to increased respiratory demands (6). Cardiovascular risks: A systematic review of studies focused on endurance exercise and air pollution shows that athletes exposed to elevated PM2.5 levels were significantly impacted with cardiovascular health problems (7). Mental health impacts: Chronic inflammation from poor air quality is associated with increased risk of depression and anxiety, undermining the mood-boosting effects of physical activity (8). When to adjust your workout for air quality Air quality doesn’t have to be “Hazardous” to affect exercise performance. Because breathing rates increase during physical activity, even moderate pollution can have a greater impact during intense or prolonged workouts. The key is knowing whether you’re responding to indoor air conditions or outdoor pollution levels—and adjusting accordingly. Indoors: watch ventilation and buildup For indoor workouts, elevated PM2.5 levels or carbon dioxide (CO₂) concentrations above 1,000 parts per million (ppm) can signal that ventilation may be inadequate—especially in crowded or enclosed spaces. When these levels rise, lowering workout intensity, shortening duration, improving ventilation, or choosing a less crowded space can help reduce unnecessary strain on the lungs and cardiovascular system.Outdoors: use air quality ranges to guide decisionsFor outdoor exercise, PM2.5 and overall air quality levels are more useful decision tools. As a general guide: Good (0–25): Air quality is good. Outdoor exercise is generally safe. Moderate (26–50): Air quality is acceptable, but sensitive individuals may notice symptoms during outdoor exercise. Moderately Unhealthy (51–100): Pollutants may affect breathing even in healthy individuals. Consider exercising indoors or keeping outdoor workouts shorter and less intense. Unhealthy for Sensitive Groups (101–150): Everyone may be affected, especially those with heart or lung conditions. Indoor exercise is the safer choice. Very Unhealthy (151–200): Health effects are more likely for everyone. Avoid outdoor exercise. Hazardous (201–500): Air quality is poor enough to pose serious health risks. Stay indoors and avoid physical exertion. Using these ranges helps shift workouts to safer times, locations, or environments—without avoiding exercise altogether. Using air quality data to plan your workouts Air quality can change quickly due to traffic patterns, weather, and human activity. Pollution levels that are low early in the day may rise within hours, particularly during rush hour or in enclosed indoor spaces with high occupancy. Checking real-time air quality data and short-term forecasts helps you decide when and where to exercise with less exposure. Monitoring pollutants like PM2.5 and carbon dioxide allows you to adjust workout timing, intensity, or location accordingly—such as exercising earlier, choosing a less crowded space, or prioritizing indoor workouts when outdoor air quality is poor. Indoor vs. Outdoor Exercise: Which Is Better? When air quality is poor, the choice between exercising indoors or outdoors isn’t always straightforward. Outdoor workouts may offer better airflow, but they also expose you directly to pollution from traffic, industry, wildfire smoke, and other airborne contaminants. Indoor exercise can reduce exposure when ventilation and filtration are adequate, but poorly ventilated gyms or studios can allow pollutants like PM2.5 to accumulate—especially during busy classes or peak hours. In general, the better option depends on conditions: When outdoor air quality is good, exercising outside or ventilating indoor spaces can be beneficial. When outdoor air quality is poor, well-filtered and properly ventilated indoor environments are often the safer choice. Monitoring air quality both indoors and outdoors helps you choose the option that minimizes exposure while still supporting your fitness goals. How to exercise safely indoors Indoor exercise can be made safer with a few practical adjustments. Paying attention to ventilation, filtration, and air quality helps reduce unnecessary exposure during workouts. Choosing a gym or fitness studio: Prioritize facilities with high performance air purifiers. Ask staff about their ventilation systems and cleaning protocols.

Parks or open-air studios provide better airflow than indoor studios. Download a free air quality app to know what the air is like before you go outdoors to exercise. At home: Use an indoor air quality monitor to track PM2.5 and CO2 levels in real time. Use in tandem with an outdoor air quality monitor to know when outdoor air could impact indoor air quality.

And when the holiday season comes around, special circumstances arise. When prepping homes, most consider only the cleanliness of surfaces like tabletops, counters, or floors, ensuring they are free of dust, dirt, and grime. Read on for 7 essential tips for handling holiday housecleaning and indoor air quality challenges. 1. Be mindful of entries and departures—guests bring more than food and presents. Like it or not, with the arrival of guests comes the arrival of dirt and dust. Household dust includes airborne particles blown in from outdoors, dead skin cells and hair from people and pets, dust mite bodies and droppings, tracked-in soil, and pollen (1). So, during the holidays, when opening doors for guests’ entrances and exits, dust comes in with the wind. Also, sources of dust cross the threshold on guests’ shoes and clothing. And since every guest has skin and hair, this tool adds to the dusty buildup. Solutions: To reduce dust, start by placing mats in front of every door. Encourage guests to remove their shoes at the door. Not only will guests be more comfortable, but your home will stay cleaner for your guests as well. If the air is polluted outdoors, don’t open the door for guests until all goodbyes have been said. Hanging around with the door wide open invites more contaminants into your home. 2. More time indoors, more indoor air pollutants. Dust With chillier outdoor temperatures, we, along with our guests and our pets, tend to be indoors more, shedding skin cells and hair. This is why household dust tends to increase during the holidays. Plus, our heaters are operating more often. Radiant heating systems don’t make much of mess in your house, but central, forced-air systems can add to the dust in the air and on surfaces. Wood stoves, which can certainly warm us up, not only create dust and ash, but the smoke from them can produce buildups of soot on surfaces. The common cold, flu and other viruses Keep in mind, the quality of your indoor air can also affect whether you or your guests contract and spread cold, the flu and other viruses. And while there is no cure for a cold, research does show that once you have a cold, the quality of the air you breathe has a significant effect on the severity of your symptoms. As you gear up for your holiday festivities, here are a few things you can do to deal with the increased time indoors and make sure your air is a clean as possible (2): Replace or clean your HVAC air filters regularly (at least every 3 months but more often if needed). Use portable electric heaters where reasonable. Use wood stoves that include a HEPA filter. Consider acquiring a whole-house air purifier system that works with your HVAC system to ensure every room has clean indoor air quality. 3. Fireplace: not be such a hot idea. Fireplaces, even fully gas-burning models, can significantly increase the number of airborne contaminants in your home. Firewood smoke in particular has been linked to strokes, heart disease, and lung cancer (3) (4). And like a wood stove, firewood smoke can stain household surfaces. Wood-burning fireplaces also create dust and ash that not only make a mess, they can also irritate airways and exacerbate asthma and allergy symptoms. Solutions The best way to prevent a fireplace from sullying your house and harming your indoor air quality and the health of you and your loved ones is to not use it. But if that is not practical: Use an air purifier in the room where the fireplace is For wood-burning fireplaces (5): Use wood, preferably hardwood, that was split, dried, and covered for at least six months. Install heat-proof glass doors. Regularly clean your fireplace’s interior to remove the dust and ash, while wearing a high-quality protective face mask to avoid breathing in these harmful particles. Make sure your air purifier is specifically designed to remove smoke and odors from the air. 4. Avoid burning candles, scented or not. Lighted candles are a common way to enhance the atmosphere during special holiday gatherings, but they create housecleaning issues much like a fireplace, and can add volatile organic compounds (VOCs) and ultrafine particles to your air. Scented candles, which usually use synthetic fragrances and dyes, can emit VOCs even when they are not lit (6). Solutions Use unscented candles to enhance your décor; maintain clean indoor air quality by not lighting them. To fill your house with wonderful holiday scents without adding contaminants to the air: Simmer fragrant spices like cinnamon sticks, cloves, and nutmeg in a pot of water. Diffuse essential oils (try to avoid fragrance oils that contain artificial ingredients). Place containers of potpourri around your home. 5. Prevent mold and pollen buildup. Planning on buying a holiday tree from a tree lot? You might want to reconsider. Besides the clutter from falling needles, these trees can add mold and pollen to household surfaces and produce indoor air quality that is inhospitable to those with allergies and asthma. After the trees are cut, they are tightly bundled, creating an environment for the growth of up to 50 types of mold, which have been found to increase the typical presence of mold spores in indoor air by more than six times in less than two weeks (7) (8). The trees can also be a source of pollen, which, besides being another allergen and asthma trigger, is an ingredient in dust. Paradoxically, it is not the tree’s own pollen grains but grains like ragweed pollen that settled on the tree and grass pollen that got stuck to the tree’s sap and is released when the sap dries out. Solutions To prevent Christmas trees from adding to an untidy home and unhealthy air: Use a reusable, artificial tree If you do buy a tree from a lot: Consider placing the tree outdoors within view from inside If that is not feasible: Clean and wipe the trunk of your tree thoroughly with water and bleach before you bring it into the house. Use a leaf blower to remove as many pollen grains as possible before bringing the tree indoors. Put the tree up later and get rid of it sooner. Cut the tree yourself, bypassing the storage and transportation conditions that promote mold growth. Use a high-performance room air purifier in the same room as the tree to help create good indoor air quality. 6. Cook with care. Who doesn’t love a holiday feast? But be careful—with increased cooking activities comes more grease and smoke stains. And gas stoves can add dangerous particulates to the air, such as nitrogen dioxide, which has been linked to asthma in children (9). Solutions Use ventilation fans when you cook. If you have a gas oven and stove, use electric cooking appliances such as a small oven or microwave when possible, instead. Use a personal air purifier when cooking to ensure your personal breathing zone is safe. 7. Use smart cleaning techniques before, during, and after the festivities. The additional housecleaning chores caused by the increased activities and visitors around the holiday season can also harm indoor air quality. So it’s important to focus on methods of cleaning that actually clean your home’s surfaces while sparing the air around you and your guests. For instance, many cleaning solvents release harmful chemicals into the air, including ammonia, chlorine, perchloroethylene or “perc,” 2-butoxyethanol and sodium hydroxide, better known as lye (10). Try to avoid cleaning products that include these and use sparingly if they can’t be avoided. Also, take care when purchasing cleaning products labeled “green” or “natural” as they too can contain ingredients that are harmful to your health (11). You can always refer to the comprehensive “Safer Choice” list provided by the U.S. Environmental Protection Agency, which includes cleaning products for home and vehicles (12). Finally, avoid improper dusting techniques that kick up and add more airborne dust to your breathing space that irritates eyes and airways and must be cleaned again once it settles. Solutions Use warm water and mild soap as a general household cleaning product. Instead of abrasive cleaners for scrubbing, use baking soda. For windows and other glass surfaces, use a mixture of vinegar and water. Avoid “dry-dusting,” and instead use a rag dampened with water. Rather than sweeping floors, which kicks up dust, use a vacuum with a HEPA filter that traps dust and dirt particles preventing them from returning to the air. Use a vacuum with a dusting attachment for items that are hard to dust like lampshades and drapes. Conclusion Maintaining a clean and healthy home, including good indoor air quality, might take a little extra work during the holidays. But in between the chores, you and your loved ones will better enjoy the festivities. A cleaner home means a healthier home, and after all, healthier holidays are happier holidays.","

Local air pollution sources Localized air pollution sources and air pollution concentrations over time can vary dramatically from building to building based on location and operating hours. For example, office buildings near busy streets or highways may experience their highest levels of air pollution during morning and afternoon vehicle traffic. Vehicle exhaust is a major source of PM2.5, ultrafine particles (UFPs), chemicals, and volatile organic compounds (VOCs).1,2 Air filtration must be designed not only to help reduce outdoor air pollution that can seep indoors but also remove indoor air pollutants from furnishings, construction materials, and personal hygiene products that can impact employee health and productivity.

Despite the age of a building, our Solutions Engineers can design filtration solutions that can be retrofitted into existing heating, ventilation, and air conditioning (HVAC) systems or customize stand-alone solutions for any facility. Expert consultation Evaluations (onsite or virtual) by subject matter experts in commercial air quality and air filtration systems can help simplify this process through the following steps: Building walkthrough: Facility construction, HVAC systems, and existing air filtration (if applicable) are documented. Spot measurements of ambient air quality: Major sources of air pollution, both indoors and outdoors, are documented using high-accuracy air quality monitoring tools. Inspection of air handlers and air distribution: Current facility HVAC and air filtration technology, including outstanding maintenance and upgrades, are noted. Detailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements. Based on evaluation results, one or more of the following solutions may be proposed: HVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork. Localized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace. Individualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone. Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.6 However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs). MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways: increased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort ventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters. NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.7 Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements. The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements. Refer to the table below for a side-by-side comparison of filtration efficiencies for MERV 13 air filters and NanoMax air filters. MERV 13 NanoMax Improvement in Efficiency with NanoMax 3-10 microns up to 90% up to 100% ~11% 1-3 microns 80-85% up to 99% Up to 24% 0.3-1 micron ≤ 50% up to 96% Up to 174% < 0.1 micron Not tested 90% Substantial Fewer HVAC filter changes NanoMax filters require fewer filter replacements over time. This can significantly reduce the costs associated with filter purchases and labor involved in filter replacements. Refer to the table below for an example of cost savings with NanoMax in comparison to MERV 13 filters for a facility using 50 NanoMax filters. Filter Replacement Intervals* Yearly Maintenance Hours (15 min./filter) Yearly Filter Costs MERV 13 4 times per year 50 hours $2,000-$8,000 NanoMax(exceed MERV 16 performance 1 time per year 12.5 hours $5,000 * based on 8 hours of HVAC operation per day (2,920 hours). Energy management Unlike many traditional MERV 13 air filtration systems, NanoMax HVAC air filters used as part of the Clean Air Facility program do not require additional mechanical ventilation beyond what is required per building code. As a result, buildings can only operate HVAC air filtration systems as needed to reduce energy usage. This helps minimize a building’s carbon footprint while maintaining 90 to 100 percent air filtration efficiency for particles while the building is occupied and HVAC systems are operating. Air quality monitoring and smart technology Smart indoor climate systems and other building control systems can also be paired with indoor and outdoor air quality monitoring to automate HVAC air filtration systems using preset protocols: HVAC Systems: Program smart thermostats to maintain energy-efficient “Fan On” mode and deliver clean air even in the absence of heating or cooling operations. High-Capacity Stand-Alone Systems: Pair air purifiers with occupancy sensors, timers, or air quality monitors so that systems operate when indoor spaces are occupied or indoor air pollution concentrations surpass pre-programmed thresholds. Air quality verification and monitoring The impact of PM2.5 and indoor gases like carbon dioxide (CO2) on employee health, productivity, and cognitive performance has long been documented.8,9,10,11 Air quality monitoring can provide crucial data to help ensure that HVAC systems supplies sufficient levels of clean and oxygenated air to occupants and reduce the health impacts of air pollution and airborne infections. You will receive an air quality report every month for your facility. You will be contacted within 4 business hours if there is an issue with your facility’s air quality. Public air quality data displays can also demonstrate to building inhabitants the immediate benefits of indoor clean air, especially when outdoor air pollution is heavy. This data can be displayed on publicly visible TV monitors or on company websites using customizable air quality data widgets (see Figure 1 for an example). Figure 1: Customized air quality widget for websites, comparing current indoor air quality with outdoor air quality. Long-term air quality data can also illustrate the returns of investment in air filtration alongside other workforce data, such as work absences due to illness and productivity metrics. Further benefits of indoor and outdoor air quality monitoring include: Live indoor air quality data feed to demonstrate real-time air quality improvements resulting from air filtration. Mobile air quality apps for facility inhabitants to view real-time workplace air quality data anywhere. Email notifications for specified air quality thresholds, alerting facility stakeholders about potential air pollution threats. Documentation of indoor air quality improvements to track the long-term efficacy of air filtration and air quality improvement programs. Air quality reports featuring long-term data that can illustrate the relationship between air quality improvements and workplace metrics. Lookup your facility here (bottom of this page https://www.iqair.com/us/commercial-applications/clean-air-facilities): Maintenance and renewal Clean Air Facility status is active for 12 months after successful designation. Facilities with active Clean Air Facility designations are listed on the public, searchable IQAir Clean Air Facility database. Buildings that meet Clean Air Facility requirements can publicly display a customized placard, window decal, or countertop trophy indicating that the facility meets strict indoor air quality and infection control requirements (see Figure 2 for an example). Figure 2: Example of Clean Air Facility window decal displayed in public view. In conclusion The Clean Air Facility program helps reduce the challenges of implementing office air filtration by customizing solutions to the exact specifications of any facility. Clean air at work is more than just an added bonus – it’s essential for many employees to feel safer and more secure against the new realities facing shared workspaces. Some commercial facilities are eligible for grants earmarked to help meet air filtration compliance requirements related to local air pollution or federal emergency declarations.","

\nLocalized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace.
\nIndividualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone.

Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.⁶

However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs).

MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways:

\nincreased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort
\nventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems

IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters.

NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.⁷ Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements.

The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements.

Refer to the table below for a side-by-side comparison of filtration efficiencies for MERV 13 air filters and NanoMax air filters.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

	MERV 13	NanoMax	Improvement in Efficiency with NanoMax
3-10 microns	up to 90%	up to 100%	~11%
1-3 microns	80-85%	up to 99%	Up to 24%
0.3-1 micron	≤ 50%	up to 96%	Up to 174%
< 0.1 micron	Not tested	90%	Substantial

Fewer HVAC filter changes

NanoMax filters require fewer filter replacements over time. This can significantly reduce the costs associated with filter purchases and labor involved in filter replacements.

Refer to the table below for an example of cost savings with NanoMax in comparison to MERV 13 filters for a facility using 50 NanoMax filters.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

	Filter Replacement Intervals*	Yearly Maintenance Hours (15 min./filter)	Yearly Filter Costs
MERV 13	4 times per year	50 hours	$2,000-$8,000
NanoMax (exceed MERV 16 performance	1 time per year	12.5 hours	$5,000

* based on 8 hours of HVAC operation per day (2,920 hours).

Energy management

Unlike many traditional MERV 13 air filtration systems, NanoMax HVAC air filters used as part of the Clean Air Facility program do not require additional mechanical ventilation beyond what is required per building code.

As a result, buildings can only operate HVAC air filtration systems as needed to reduce energy usage. This helps minimize a building’s carbon footprint while maintaining 90 to 100 percent air filtration efficiency for particles while the building is occupied and HVAC systems are operating.

Air quality monitoring and smart technology

Smart indoor climate systems and other building control systems can also be paired with indoor and outdoor air quality monitoring to automate HVAC air filtration systems using preset protocols:

\nHVAC Systems: Program smart thermostats to maintain energy-efficient “Fan On” mode and deliver clean air even in the absence of heating or cooling operations.
\nHigh-Capacity Stand-Alone Systems: Pair air purifiers with occupancy sensors, timers, or air quality monitors so that systems operate when indoor spaces are occupied or indoor air pollution concentrations surpass pre-programmed thresholds.

Air quality verification and monitoring

The impact of PM2.5 and indoor gases like carbon dioxide (CO₂) on employee health, productivity, and cognitive performance has long been documented.^8,9,10,11

Air quality monitoring can provide crucial data to help ensure that HVAC systems supplies sufficient levels of clean and oxygenated air to occupants and reduce the health impacts of air pollution and airborne infections. You will receive an air quality report every month for your facility. You will be contacted within 4 business hours if there is an issue with your facility’s air quality.

Public air quality data displays can also demonstrate to building inhabitants the immediate benefits of indoor clean air, especially when outdoor air pollution is heavy. This data can be displayed on publicly visible TV monitors or on company websites using customizable air quality data widgets (see Figure 1 for an example).

$\"AirVisual$

Figure 1: Customized air quality widget for websites, comparing current indoor air quality with outdoor air quality.

Long-term air quality data can also illustrate the returns of investment in air filtration alongside other workforce data, such as work absences due to illness and productivity metrics.

Further benefits of indoor and outdoor air quality monitoring include:

\nLive indoor air quality data feed to demonstrate real-time air quality improvements resulting from air filtration.
\nMobile air quality apps for facility inhabitants to view real-time workplace air quality data anywhere.
\nEmail notifications for specified air quality thresholds, alerting facility stakeholders about potential air pollution threats.
\nDocumentation of indoor air quality improvements to track the long-term efficacy of air filtration and air quality improvement programs.
\nAir quality reports featuring long-term data that can illustrate the relationship between air quality improvements and workplace metrics.

Maintenance and renewal

Clean Air Facility status is active for 12 months after successful designation. Facilities with active Clean Air Facility designations are listed on the public, searchable IQAir Clean Air Facility database.

Buildings that meet Clean Air Facility requirements can publicly display a customized placard, window decal, or countertop trophy indicating that the facility meets strict indoor air quality and infection control requirements (see Figure 2 for an example).

In conclusion

The Clean Air Facility program helps reduce the challenges of implementing office air filtration by customizing solutions to the exact specifications of any facility.

Clean air at work is more than just an added bonus – it’s essential for many employees to feel safer and more secure against the new realities facing shared workspaces.

Some commercial facilities are eligible for grants earmarked to help meet air filtration compliance requirements related to local air pollution or federal emergency declarations.

Po Valley will host the upcoming Winter Olympics when pollution is at its peak. What can be done to ensure athlete and spectator safety?

","In February 2026, Milan, Italy and the surrounding Po Valley will host the Winter Olympics, a global celebration of athletic excellence set against one of Europe’s most persistent winter air quality challenges. The Po Valley in northern Italy routinely experiences winter smog. This intersection of Olympic athletic competition and poor air quality raises concerns for the health and performance of both athletes and spectators. Where will the 2026 Olympic games be held? The 2026 Milan-Cortina Winter Olympic games will be held in three northern provinces of Italy – Lombardy, South Tyrol, and Veneto from February 6 through 22 (1). While most of the stadiums, arenas, and parks are in the surrounding Alps, the two largest participating cities – Milan and Verona – lie in the Po Valley. Five arenas and stadiums in Milan will host indoor-only events and the opening ceremony, while Verona Olympic Arena will host the closing ceremonies. Other venue locations include: Anterselva / Antholz, South Tyrol Bormio, Lombardy Cortina d’Ampezzo, Veneto Livigno, Lombardy Predazzo, Trentino Tesero, Trentino All locations, with the exceptions of Tesero and Verona, will house Olympic Villages where athletes will reside during the games. Why is the Po Valley’s air quality poor in winter? The Po Valley’s unique geography plays a central role in trapping pollutants: the valley is hemmed in by the Alps to the north and the Apennine Mountains to the south, creating a natural basin that traps cold air and pollutants. This \"bowl effect\" is compounded by meteorological conditions, particularly in winter, when temperature inversions occur. During these inversions, a layer of warm air settles above the cooler air near the ground, acting like a lid that prevents pollutants from dispersing upward or outward. As a result, pollutants can linger over the valley for days or even weeks. Human activity degrades the region’s poor air quality. Human activity affects the region’s air quality. The Po Valley is home to some of Italy’s most industrialized areas, where factories release PM2.5 – particulate matter measuring 2.5 micrometers in diameter or smaller – and nitrogen oxides (NO2) (2). Agriculture also contributes pollutants, as livestock farming produces ammonia, which reacts with industrial and vehicle emissions to create secondary particulate matter. According to a 2024 study, livestock farming may be responsible for as much as a quarter of Lombardy’s air pollution (3). Smoke from residential wood burning impacts winter air quality in the Po Valley (4). Vehicle emissions, particularly in major cities like Milan and Turin, are also sources of nitrogen dioxide and PM2.5 (5). These geographic and emissions-related factors are reflected in Milan’s long-term air quality data—but annual averages can mask the severity of winter pollution. In 2024, Milan's annual average PM2.5 concentration was 17 µg/m3. This was 3.4 times the WHO annual guideline of 5 µg/m3. However, this figure blends relatively cleaner summer conditions with much higher winter concentrations. During peak winter months, pollution levels rise sharply. In February 2025, Milan’s average monthly PM2.5 concentration was 32.1 µg/m3. These winter pollution episodes are often driven by stagnant air and temperature inversions rather than predictable daily emission cycles. Air quality in surrounding Alpine valleys may also be affected by residential wood burning combined with inversion conditions (6). Air quality lessons from past Olympics Previous Olympic host countries have struggled with poor air quality and have had to take measures to ensure health and safety. Beijing, China faced the potential for severe air pollution while hosting the 2008 Summer Olympics – and officials took proactive measures. In the months leading up to the Games, the U.S. Embassy in Beijing installed a regulatory-grade air quality monitor that exposed hazardous air quality in the city. Chinese authorities enacted sweeping temporary measures, including shutting down factories, and restricting vehicle traffic. Chinese officials implemented a robust policy shift in 2013, a year of terrible air quality for the country. The official policy response focused on long term air quality improvements – tougher coal-fired plant emissions standards, further vehicle restrictions, and initiatives to cut coal-fired home heating with electric or gas heaters (7). By the 2022 Beijing Winter Olympics, air pollution in the city was half that of both 2008 and 2013 (8). Rio de Janeiro was confronted with its own environmental crisis during the 2016 Olympics. While polluted water dominated the headlines, air quality also remained a persistent concern due to rapid development and 2.7 million vehicles in the city (9). To test those concerns, the Reuters news agency tested air quality at several Olympic sites across the city, finding a peak 24-hour average PM2.5 concentration of 65 µg/m3 at the Olympic Stadium (10). The WHO air quality guideline for an average 24-hour PM2.5 is 15 µg/m3. How winter smog can affect athletes Air pollution impacts the health and performance of those at the heart of the Olympics: the athletes. For endurance sports like cross-country skiing and biathlon, where athletes push their bodies to the limit for extended periods, polluted air reduces oxygen uptake and impairs lung function (11). Rapidly breathing in particulate matter can carry significant risks. Rapidly breathing in particulate matter can carry health risks. PM2.5 pollution penetrates deep into the lungs, triggering inflammation and narrowing airways, which can decrease stamina and slow recovery. Even short-term exposure during competition can lead to coughing, wheezing, and reduced athletic performance. High-intensity sports, such as ice hockey and speed skating, are also affected, as the increased respiratory rate during exertion means athletes inhale more pollutants, further straining their cardiovascular and respiratory systems. How winter smog affects spectators Vulnerable spectators—children, the elderly, and individuals with pre-existing conditions like asthma—face heightened risks of respiratory distress when exposed to air quality in the “unhealthy for sensitive groups” range. Outdoor venues, where events like ski jumps, open-air ceremonies, and marathon-style races take place, present the greatest exposure, as there is no barrier between the crowd and air pollution. Even indoor events may not offer full protection, as pollutants can seep inside or accumulate in poorly ventilated spaces. Po Valley residents have been demonstrably susceptible to winter air quality health risks. A study found that the highest mortality burden for European cities in 2015 was in the Po Valley, Poland, and the Czech Republic (12). And a 2025 study uncovered that infants in Northern Italy with medium-term exposure to high concentrations of pollutants experienced a greater risk of acute bronchiolitis (13). How to reduce exposure during winter smog Winter smog is a recurring reality in the Po Valley, but its health impacts can be meaningfully reduced with the right safeguards in place. What governments are doing With the 2026 Olympics looming, authorities are working to improve air quality through a mix of policy and contingency planning. At the national level, Italy has adopted air quality plans aimed at reducing traffic-related emissions, including incentives for electric vehicles and restrictions on older, high-emissions cars (14). Lombardy has expanded these efforts with additional financial incentives for electric vehicle purchases and vehicle scrappage programs. Milan has implemented low-emission zones between 2019 and 2026, covering most of the city’s traffic-related emissions (15). Local and national governments, as well as Olympics organizers, have leaned into a transportation plan that emphasizes more sustainable mass public transit improvements – in particular through rail service (16). What athletes can do Athletes may need to consider several options for protecting their health during the event. Monitor air quality. Download a free, real-time air quality app to monitor pollution levels. Wear a mask. Athletes may choose to put on a K95/FFP2 face mask on poor air quality days. Choose low-pollution routes. Steer clear of busy roads and urban areas where vehicle emissions concentrate. Train indoors. Whenever possible, move workouts indoors, particularly in spaces equipped with high-performance air purifiers.

Download a free air quality app to stay informed about air pollution in real time. Wear a K95/FFP2 face mask when venturing out on poor air quality days. Use an air purifier to reduce the concentration of PM2.5 indoors. Conclusion The 2026 Winter Olympics place Milan and the Po Valley under a global spotlight at a time when air pollution remains a persistent challenge. Protecting athlete performance and public health will depend on continued coordination between government authorities, Olympic organizers, and local stakeholders. Measures already underway—ranging from vehicle restrictions to expanded public transit and contingency planning—demonstrate that large international events can coexist with environmental risk management.

Pollution doesn’t stay outside. Discover what in the air in homes near freeways—and how to reduce risk.

","Living near a freeway brings convenience — but also invisible risks. Studies show that homes, schools, and apartments within a few hundred meters of major roadways are exposed to elevated traffic pollution (1,2). And those pollutants don’t stay outside: many seep into indoor spaces, quietly affecting health, comfort, and cognitive performance. From ultrafine particles to toxic gases, traffic emissions release a dangerous mix of pollutants. Here’s what’s entering homes near busy roads. What pollutants come from road traffic Traffic emissions are a complex cocktail of gases and particles. Some are emitted directly from engines, while others come from the wear and tear of driving itself. The most concerning include: Ultrafine particles (UFPs): Smaller than 0.1 µm, these can penetrate deep into the lungs and even enter the bloodstream. Black carbon: A marker of diesel and gasoline combustion, strongly elevated near highways. Fine particulate matter (PM2.5): Less localized than UFPs but still harmful indoors. Nitrogen oxides (NO₂/NOₓ): Emitted by engines; linked to respiratory illness. Carbon monoxide (CO): Highest near dense traffic corridors. Volatile organic compounds (VOCs): Carcinogens like benzene and PAHs from fuel. Brake, tire and road-wear particles: Release metals like copper, zinc and iron. As IQAir CEO Frank Hammes said: “Traffic is one of the major pollution sources and tailpipe emissions are among the worst.” How far and how much pollution travels Pollution concentrations are strongest right next to the road, but still measurable hundreds of meters away. Steep gradients: UFPs, black carbon, NO₂ and CO typically fall sharply within 50–200 meters. Leveling out: By 300–500 meters, levels approach background, though weather and topography matter. PM2.5: Less variable but still elevated in near-road neighborhoods. Why traffic-related pollutants enter homes If outdoor air is polluted, why does it end up inside? In short: buildings breathe. Pressure differences from wind and temperature (the “stack effect”) pull outdoor air through the building envelope—around window frames and door seals, through vents and gaps in construction, and via any HVAC system that brings in outside air for ventilation. Even when windows are closed, this slow, continuous exchange can carry roadway pollution indoors (3). Ultrafine particles are especially tricky. Because they’re smaller than 0.1 µm, they slip through tiny cracks and stay suspended in indoor air for hours, drifting from room to room and settling into fabrics and dust (4). Gases like NO₂ and VOCs can also infiltrate and spread quickly through shared ducts or open floor plans. Indoor sources can compound the problem. Cooking (especially on gas stoves), smoking, burning candles or incense, and some cleaning products add their own particles and VOCs to the air. When indoor sources stack on top of outdoor infiltration, overall exposure rises—making indoor air quality highly dependent on both the conditions outside and the way a building is sealed, ventilated, and used. The role of monitoring You can’t fix what you don’t measure. Air quality monitoring — both indoors and outdoors — is essential to understanding exposure to pollution. Indoor air quality monitors reveal how much pollution is entering your home. Outdoor monitors show real-time changes in outdoor air quality, allowing users to better understand shifts in local traffic emissions, weather, or smog events. IQAir’s AirVisual platform and app provide hyperlocal air quality data worldwide. Open windows when outdoor air is good; keep them shut during rush hour or poor air days. Together, indoor and outdoor data empower households to take timely action, such as: Closing windows during high-traffic hours. Switching HVAC systems to recirculation. Running air purifiers when outdoor air quality worsens. Monitoring creates awareness — it’s the first step toward protection. How to reduce exposure when indoors The good news: practical actions make a real difference. Minimize indoor sources: Limit smoking, burning candles, and unvented cooking. Vent smart: Open windows when outdoor air is good; keep them shut during rush hour or poor air days. Upgrade filtration: Use high-efficiency HVAC filters (MERV-13+ where possible); whole-house air purification can also provide high-performance protection. Run portable purifiers with true HEPA or HyperHEPA filters, like IQAir’s Atem Earth, to capture ultrafine particles ideally in bedrooms and living rooms. Activated carbon filtration, like that in the GC MultiGas XE air purifier, can also help filter NO₂ and VOCs. Research shows these strategies can cut particle exposure by 50–70% or more (5). Conclusion Living near a freeway means more than traffic noise — it means daily exposure to harmful pollutants. But with awareness and action, you can protect yourself. The formula is simple: Awareness (monitoring) + Action (filtration + behavior) = Better protection. Start by monitoring your air indoors and out. Use the data to guide smart choices like closing windows at peak traffic, adjusting ventilation, and running air purifiers. These steps, repeated consistently, can significantly reduce the health risks of road pollution.","

Studies show that homes, schools, and apartments within a few hundred meters of major roadways are exposed to elevated traffic pollution (1,2). And those pollutants don’t stay outside: many seep into indoor spaces, quietly affecting health, comfort, and cognitive performance.

From ultrafine particles to toxic gases, traffic emissions release a dangerous mix of pollutants. Here’s what’s entering homes near busy roads.

What pollutants come from road traffic

Traffic emissions are a complex cocktail of gases and particles. Some are emitted directly from engines, while others come from the wear and tear of driving itself. The most concerning include:

\nUltrafine particles (UFPs): Smaller than 0.1 µm, these can penetrate deep into the lungs and even enter the bloodstream.
\n
Black carbon: A marker of diesel and gasoline combustion, strongly elevated near highways.
\n
Fine particulate matter (PM2.5): Less localized than UFPs but still harmful indoors.
\n
Nitrogen oxides (NO₂/NOₓ): Emitted by engines; linked to respiratory illness.
\n
Carbon monoxide (CO): Highest near dense traffic corridors.
\n
\nVolatile organic compounds (VOCs): Carcinogens like benzene and PAHs from fuel.
\n
Brake, tire and road-wear particles: Release metals like copper, zinc and iron.
\n

As IQAir CEO Frank Hammes said: “Traffic is one of the major pollution sources and tailpipe emissions are among the worst.”

How far and how much pollution travels

Pollution concentrations are strongest right next to the road, but still measurable hundreds of meters away.

Steep gradients: UFPs, black carbon, NO₂ and CO typically fall sharply within 50–200 meters.
\n
Leveling out: By 300–500 meters, levels approach background, though weather and topography matter.
\n
PM2.5: Less variable but still elevated in near-road neighborhoods.

If outdoor air is polluted, why does it end up inside? In short: buildings breathe. Pressure differences from wind and temperature (the “stack effect”) pull outdoor air through the building envelope—around window frames and door seals, through vents and gaps in construction, and via any HVAC system that brings in outside air for ventilation. Even when windows are closed, this slow, continuous exchange can carry roadway pollution indoors (3).

Ultrafine particles are especially tricky. Because they’re smaller than 0.1 µm, they slip through tiny cracks and stay suspended in indoor air for hours, drifting from room to room and settling into fabrics and dust (4). Gases like NO₂ and VOCs can also infiltrate and spread quickly through shared ducts or open floor plans.

Indoor sources can compound the problem. Cooking (especially on gas stoves), smoking, burning candles or incense, and some cleaning products add their own particles and VOCs to the air.

When indoor sources stack on top of outdoor infiltration, overall exposure rises—making indoor air quality highly dependent on both the conditions outside and the way a building is sealed, ventilated, and used.

The role of monitoring

You can’t fix what you don’t measure. Air quality monitoring — both indoors and outdoors — is essential to understanding exposure to pollution.

\nIndoor air quality monitors reveal how much pollution is entering your home.
\nOutdoor monitors show real-time changes in outdoor air quality, allowing users to better understand shifts in local traffic emissions, weather, or smog events.
\nIQAir’s AirVisual platform and app provide hyperlocal air quality data worldwide.

Open windows when outdoor air is good; keep them shut during rush hour or poor air days.

Together, indoor and outdoor data empower households to take timely action, such as:

Closing windows during high-traffic hours.
Switching HVAC systems to recirculation.
Running air purifiers when outdoor air quality worsens.
\n

Monitoring creates awareness — it’s the first step toward protection.

How to reduce exposure when indoors

The good news: practical actions make a real difference.

Minimize indoor sources: Limit smoking, burning candles, and unvented cooking.
Vent smart: Open windows when outdoor air is good; keep them shut during rush hour or poor air days.
\n
Upgrade filtration:
\n
- Use high-efficiency HVAC filters (MERV-13+ where possible); whole-house air purification can also provide high-performance protection.
  \n
- Run portable purifiers with true HEPA or HyperHEPA filters, like IQAir’s Atem Earth, to capture ultrafine particles ideally in bedrooms and living rooms.
  \n
- Activated carbon filtration, like that in the GC MultiGas XE air purifier, can also help filter NO₂ and VOCs.
\n

Research shows these strategies can cut particle exposure by 50–70% or more (5).

Conclusion

Living near a freeway means more than traffic noise — it means daily exposure to harmful pollutants. But with awareness and action, you can protect yourself.

The formula is simple: Awareness (monitoring) + Action (filtration + behavior) = Better protection.

Start by monitoring your air indoors and out. Use the data to guide smart choices like closing windows at peak traffic, adjusting ventilation, and running air purifiers. These steps, repeated consistently, can significantly reduce the health risks of road pollution.

Millions burn biomass for heating, cooking, and crop waste removal. Find out why the cost in health and lives is too high to continue.

","Every day, nearly 3 billion people light fires to cook, heat their homes, or clear land. These fires fill the air with a toxic cocktail of pollutants. Black plumes of smoke rise from woodstoves, crop fields, and wildfires to form a long-term public health crisis. These practices are collectively known as biomass burning—the combustion of organic materials like wood, crop waste, and dung. Biomass burning pumps out PM2.5 (particulate matter measuring 2.5 microns in diameter or smaller), carbon monoxide, and other pollutants linked to millions of premature deaths each year from stroke, heart disease, and respiratory illnesses. Biomass is sometimes deemed “renewable,” but its smoke is anything but harmless. Although biomass burning occurs worldwide, its impacts extend far beyond the communities where the smoke is produced; black carbon from incomplete combustion accelerates glacier melt, disrupts rainfall, and crosses oceans. What is biomass burning? People have used biomass for energy since the earliest humans first lit wood fires for cooking and warmth. Biomass is organic material from living—or recently living—organisms, such as wood, crop residues, and animal waste. Examples of organic materials may include: Charcoal Crop waste Dung Wood Today, biomass is widely burned for cooking and heating, and, in some places, it is also used to generate electricity and power industrial systems (1). While some biomass burning results from natural processes like lightning-sparked wildfires, it is generally derived from human activity. Because biomass burning is so widespread and often happens close to where people live, its health impacts are felt most by those exposed to the smoke every day. Who breathes biomass smoke? Because biomass burning often occurs indoors or near homes, exposure falls hardest on those who spend the most time nearby. In rural homes across sub-Saharan Africa, Central and South Asia, and Latin America, women and girls spend hours each day gathered around open fires or rudimentary stoves. The consequences are devastating; the World Health Organization estimates that household air pollution from biomass kills over 3 million people annually (2). The World Health Organization estimates that household air pollution from biomass kills over 3 million people annually. Those most affected by biomass burning are also often the most vulnerable: elders, women, and children. Children under five are particularly at risk for pneumonia—the leading infectious killer of children worldwide. Even before they take their first breath, babies born to mothers exposed to biomass smoke face higher risks of low birth weight (3). For families already stretched thin by poverty, the cycle is brutal; time spent collecting firewood is time lost to education or work, and medical bills for smoke-related illnesses push millions deeper into debt. Though the impacts are most acute in less affluent regions, biomass smoke affects everyone, regardless of geography or income. In wealthier nations, wildfires are growing more intense and long-lasting due to climate change. Wildfire smoke can drift for miles and blanket cities for weeks at a time. Wood pellet burning, fireplaces, and backyard fire pits can all contribute to poor air quality as well. Where biomass is produced for energy Biomass is used very differently around the world. In some countries, it is produced at industrial scale and treated as an energy commodity—often to generate electricity, produce liquid biofuels, or supply heating fuel. Industrial biomass fuel production is greatest in the United States, which converts corn to ethanol for gasoline and electrical production. In 2024, the U.S. produced equal to about 856,000 barrels of oil (BOE) in biomass per day (4). Brazil is the second largest producer at 510,000 BOEs per day, primarily sourced from sugarcane. Indonesia produces 205,000 BOEs each day mostly from palm oil, but also from crop waste, wood, and coconut shells. China, India, and Germany follow as the next largest biofuel producers. Where biomass is burned for daily survival In contrast to industrial bioenergy production, many countries rely on biomass burning not by choice, but out of necessity. In these countries there is an overwhelming dependence on biomass burning for household cooking and heating. While biomass accounts for only about 5% of total energy use in the United States, Sub-Saharan African countries depend overwhelmingly on biomass burning for home fuel use (5): Ethiopia: 92.5% of energy comes from biomass Democratic Republic of the Congo: 92.2% Tanzania: 85% Nigeria: 81.5 Outside of Sub-Saharan Africa, other countries also heavily rely on biomass as their primary source for home heating and cooking fuel, placing entire households at daily risk of harmful smoke exposure: Haiti: 81% Nepal: 80.6% Cambodia: 66.9% Myanmar: 65.3% Guatemala: 62.8% In these regions, biomass burning isn’t an occasional source of pollution—it is a daily, unavoidable exposure that shapes health outcomes across entire communities. Why biomass burning remains widespread Biomass burning endures because for billions, wood, dung, or charcoal are either the only heating and cooking fuels they can afford—or the only fuels available. In rural villages, propane or electricity may be physically inaccessible; in crowded cities, they may be too expensive. Even when cleaner options exist, deeply rooted traditions and distrust of new technologies can slow the pace of change (6). Families often spend a high proportion of their income on fuel and healthcare costs tied to biomass yet lack the upfront cash to switch to cleaner options. Subsidies for wood pellets and lax regulation enforcement on wood burning stoves and heaters also keep the practice alive, even though wood burning smoke is linked to heart and lung diseases (7)(8).

Air pollution impacts the most at-risk, marginalized communities in the world – find out why, and what can be done to right this environmental wrong.

","Yes, air pollution is a social justice issue. Every year, 7 million people die prematurely due to air pollution, which disproportionately impacts the world’s most vulnerable populations. Low- and middle-income countries shoulder nearly 90% of these deaths, with marginalized communities—particularly women, children, and Indigenous peoples—facing the highest exposure to air pollution (1). Yet the true scale of the problem often remains hidden. Underserved urban areas and industrial zones frequently lack adequate air quality monitoring, leaving residents unaware of the pollutants they breathe each day. Without reliable local data, health risks go unrecognized, policy responses lag, and communities are left without the tools needed to advocate for cleaner air. Air pollution becomes a social justice issue not only because of who is exposed, but because exposure, measurement, and protection are distributed unevenly by design. Who breathes the dirtiest air? Patterns of air pollution exposure closely mirror patterns of race, income, and political power—both within countries and across regions. A large body of research shows that racial minorities and low-income populations—across both urban and rural settings—are disproportionately exposed to fine particulate matter (PM2.5) and industrial emissions, even within the same cities and neighborhoods. According to the landmark 1987 Toxic Wastes and Race in the United States report by the United Church of Christ, race was the strongest predictor of proximity to hazardous waste sites nationwide—stronger than income, home value, or urbanization. The study’s national findings revealed a clear and consistent pattern: Communities with no commercial hazardous waste facilities averaged 12% minority populations (the national average at the time). Communities with one facility averaged 24% minority populations—double the national average. Communities with multiple facilities or one of the nation’s largest landfills averaged 38% minority populations, more than three times the national average. Three out of five Black and Hispanic Americans lived in communities with uncontrolled toxic waste sites. These results were statistically significant at 99.99% confidence, making chance an implausible explanation. Decades of subsequent research have reinforced these findings, showing that such disparities persist through modern infrastructure development, zoning decisions, and transportation planning (2)(3). In the United States, for example, regulatory air quality monitors are used to enforce the Clean Air Act. However, a study published in The Journal of the American Medical Association found that many communities—particularly non-white and low-income neighborhoods—are routinely underserved by these monitoring networks, especially for pollutants such as lead and sulfur dioxide (4). As a result, harmful exposures can remain undetected and unaddressed. Without measurement, pollution remains invisible—and what isn’t measured is rarely prioritized. In the United States, this invisibility has real regulatory consequences. Clean Air Act protections are enforced using data from U.S. EPA regulatory air quality monitors, which determine whether areas meet national health standards and trigger enforcement actions. When monitors are missing from predominantly non-white or low-income neighborhoods—as multiple studies have shown—those communities are less likely to be counted in attainment decisions, mitigation plans, or regulatory responses. In practice, uneven monitoring can mean uneven protection under the law (5). These disparities are not unique to the United States—they reflect a broader global pattern. In Australia, rural Indigenous populations are more likely to experience elevated exposure to PM2.5 and PM10 due to dust, bushfire smoke, and woodfire cooking practices (6). Across regions, communities with fewer resources are more likely to live closer to pollution sources—and less likely to benefit from monitoring, mitigation, or enforcement. Health gaps caused by air pollution The health consequences of unequal air pollution exposure are significant and long-lasting, particularly for children and other vulnerable groups. Children growing up in polluted neighborhoods—especially those near highways, industrial facilities, or waste sites—face higher rates of asthma and respiratory illness. Elevated asthma prevalence linked to both indoor and outdoor air pollution has been documented across continents (7). In California’s Inland Empire, for example, pediatric asthma emergency department visits reached 60.5% in San Bernardino County and 59.3% in Riverside County, compared to a statewide average of 56.7% (8). These regions are characterized by basin-like geography that traps vehicle and industrial emissions, leading to sustained periods of poor air quality (9). The impacts extend beyond childhood. Long-term exposure to PM2.5 has been associated with reduced life expectancy—by as much as one to two years in highly polluted areas—particularly where pollution levels exceed World Health Organization guidelines (10). Globally, nearly 2 million new pediatric asthma cases each year are attributed to traffic-related nitrogen dioxide (NO2) exposure alone (11). When preventable health burdens follow the same social and economic lines as pollution exposure, the issue moves beyond public health and into the realm of equity. Systemic barriers to clean air Unequal exposure to air pollution is rarely accidental. It is often the result of policy decisions, planning practices, and enforcement gaps that accumulate over time. Weak enforcement of environmental regulations, limited access to clean technologies, and exclusionary urban planning practices contribute to a cycle of vulnerability that affects marginalized communities worldwide. One well-documented example occurred in Flint, Michigan, where a 2014 switch to a contaminated water source exposed predominantly Black residents to lead for years. The Michigan Civil Rights Commission later concluded that “historical, structural, and systemic racism” played a critical role in the harm experienced by the community (12). Similar patterns appear internationally: Jakarta, Indonesia: lower-income neighborhoods experience higher pollution levels due to waste burning and cooking fires (13). South Africa: Black and low-income communities located near coal plants and mining operations face some of the country’s highest pollution levels, while wealthier areas benefit from stricter regulation and more green space (14). India: Dalit communities are disproportionately located near industrial zones and coal mines, reflecting long-standing caste-based and economic inequities (15) (16). Across these contexts, communities with the least political and economic leverage are consistently those most exposed to environmental harm. Exposure is often reinforced not just by pollution sources, but by how cities and communities are designed. These environmental burdens are often compounded by exclusion from planning and decision-making processes. Neighborhoods with fewer trees, more paved surfaces, and limited green infrastructure experience higher heat stress, reduced air circulation, and greater vulnerability as climate change intensifies existing disparities. Fighting environmental injustice, protecting community health Efforts to address air pollution inequities increasingly involve a combination of grassroots advocacy, policy reform, and expanded access to data. Some governments have begun to act, though progress remains uneven. India’s National Clean Air Programme, launched in 2019, aims to reduce PM2.5 levels in the country’s most polluted cities, while citizen-led court cases in countries such as Pakistan and Indonesia have established government responsibility for protecting public health through improved air quality management (17). While these efforts represent important progress, they also highlight how much opportunity remains to reduce inequities more systematically.

Will an air purifier help protect your baby's nursery from pollutants? Discover what to look for and what to avoid.

","Air purifiers can significantly improve air quality in babies’ nurseries, helping protect their developing lungs and reducing exposure to harmful pollutants, allergens, and airborne germs. Cleaner indoor air may help reduce exposure to airborne germs and irritants that contribute to congestion or frequent respiratory discomfort, supporting more consistent sleep and feeding routines during infancy. When used correctly, and in tandem with a layered approach to optimizing the air in their nursery, air purifiers create a safer, healthier environment for infants. Why babies and newborns are especially vulnerable to poor air quality Babies breathe faster than adults and have smaller, developing airways, making them more susceptible to respiratory irritation, infections, and long-term health issues (1). Indoor air in nurseries often contains invisible threats like fine particles (PM2.5), volatile organic compounds (VOCs) from furniture or cleaning products, allergens, and even bacteria or viruses. Because babies breathe more rapidly and spend much of their time sleeping, it's important to maintain cleaner air that can help support a calmer breathing environment. Common indoor air pollutants in baby nurseries Nurseries can harbor a mix of pollutants that are particularly harmful to babies. These include: Fine particles (PM2.5 and ultrafine): From dust, pet dander, or outdoor pollution seeping indoors, these particles can penetrate deep into developing lungs. VOCs and chemicals: Released by new furniture, flooring, paints, and cleaning supplies, these can irritate airways and contribute to long-term health risks. Allergens: Dust mites, mold spores, and pollen can trigger allergies or asthma symptoms. Airborne germs: Bacteria and viruses linger in the air, increasing the risk of infections. Ozone and ionizer byproducts: Some air purifiers generate ozone, a known lung irritant that can worsen respiratory issues—these should always be avoided in nurseries. Is an air purifier good for a baby or newborn? For babies and newborns, the primary benefit of an air purifier is reducing continuous exposure to fine particles and chemical irritants during critical periods of lung and immune system development. High-quality air purifiers with HyperHEPA filtration and activated carbon are most effective for nurseries. HyperHEPA filters capture 99.95% of airborne particles, including the smallest and most harmful ultrafine particles. Activated carbon filters help remove odors and VOCs. What to look for in an air purifier for a baby’s nursery Not all air purifiers are safe for nurseries. Parents should prioritize: HyperHEPA filtration: Ensures removal of fine particles without producing ozone. Ozone-free: Ionizers and ozone-generating purifiers should be avoided, as ozone can harm developing lungs. Low noise levels: Babies are sensitive to sound; look for models offering soft, low decibel, ultra-quiet performance. Smart sensors: Real-time monitoring helps maintain optimal air quality, especially during sleep. Best practices for using an air purifier in a baby’s nursery Small setup and usage choices can make a meaningful difference in how effectively an air purifier supports a baby’s nursery environment. To maximize benefits: Run the air purifier continuously, especially during sleep, when babies are most vulnerable to airborne irritants. Ensure proper ventilation when outdoor air quality is good. Clean or replace filters when your air purifier notifies you that it is time. Air purifiers aren’t enough: How to improve air quality in a baby’s room While air purifiers are powerful tools, a layered approach ensures the best protection: Reduce sources of pollution: Choose low-VOC furniture, non-toxic cleaning products, and fragrance-free detergents. Regular cleaning: Dust surfaces, vacuum with a HEPA-filtered vacuum, and wash bedding weekly to minimize allergens. Monitor air quality: Use an indoor air quality monitor to track PM2.5, CO2, temperature, and humidity levels. Limit soft furnishings: Carpets, stuffed animals, and heavy drapes trap dust and allergens; opt for washable, hypoallergenic materials.

","Is the air quality good in Incheon? On February 20, 2026, at 8:00 AM PT, air quality in Incheon, South Korea is in the unhealth for sensitive groups range. Most of South Korea is experiencing air quality in the unhealthy for sensitive groups to unhealthy range due to a combination of factors. Poor air quality is partially a result of dust from outside Korea, in addition to stagnant winter weather, industrial pollution and vehicle emissions, nighttime biomass burning, and possibly sea salt (1)(2)(3).

Seoul was the 11th most polluted major city and Busan was the 23rd. Click here for a real-time air quality map of Incheon. While the air quality today is poor, it should be noted that the average PM2.5 concentration in 2024 for Incheon was 19.1 µg/m³, corresponding to an AQI of 65 (“moderate”), and was 3.8 times the WHO annual guideline of 5 µg/m³.

China grapples with poor air pollution, affecting major cities and public health. Learn more about the impacted regions, underlying causes, and expected improvements.

","Is the air quality good in China? As of February 19, 2026, air quality in China remains poor, with major cities experiencing air quality in the \"unhealthy\" to \"very unhealthy\" range and high PM2.5 concentrations, posing serious health risks to residents, especially children and the elderly. By 9:00 PM (Pacific Standard Time), several urban centers have recorded AQI readings above 200, prompting health warnings. Residents are advised to limit outdoor activity, keep windows closed, wear masks when outside, and use air purifiers indoors. While conditions remain poor, China’s average PM2.5 concentration in 2024 was 31 µg/m3, equivalent to an AQI of 90, classified as \"moderate\". This level is nearly 6.2 times higher than the WHO annual guideline of 5 µg/m3, placing China among the world’s 25 most polluted countries in 2024.

As of February 19, 2026, several major cities across China are reporting poor air quality. Some of the affected cities include: Baoding Beijing Chengdu Chongqing Fuxin Jinzhou Karamay Kashgar Ordos City Qingdao Shihezi Shuozhou Tangshan Tianjin Wuhan Air quality conditions can change rapidly throughout the day. For a complete, real-time overview of pollution levels nationwide, see China's air quality map. Chengdu, Chongqing, Wuhan, Beijing and Shenzhen, ranked among the most polluted major cities globally, as of 9:00 PM (PST) on February 19, 2026, according to IQAir. When will the air quality improve in China? Short-term improvements in air quality depend on favorable weather, as winds and rainfall can disperse pollutants within days. However, stagnant conditions and winter temperature inversions often trap smog from October through February, prolonging poor air quality. Long-term relief will require stricter emission controls, cleaner energy adoption, and effective seasonal policies to prevent recurring winter pollution episodes. What is causing poor air quality in China? Winter air pollution in China mainly stems from increased emissions during the heating season and unfavorable weather conditions. Coal- and biomass-fired residential heating in northern regions release large amounts of particulate matter and sulfur dioxide (SO₂) (1). Industrial sectors such as power plants, steel, cement, and chemical facilities contribute additional pollutants, while open biomass and straw burning in rural areas further worsen air quality (2). During winter, temperature inversions, shallow boundary layers, weak winds, and high humidity trap pollutants close to the ground and enhance secondary aerosol formation from SO₂, NOₓ, NH₃, and VOCs (3). Despite progress through clean-air policies, inconsistent enforcement and industrial relocation continue to pose challenges. Consequently, winter haze results from a combination of emissions, atmospheric chemistry, and regional transport (4). How can I protect myself from poor air quality?

Wildfire smoke inhalation puts pregnant women and their unborn children at a higher risk than the general population. Older adults. This population is at-risk due to an increased rate of pre-existing heart and lung disease. Anyone with a respiratory disease. Individuals with emphysema, chronic bronchitis, COPD, asthma, or another respiratory disease are at-risk. Individuals with heart disease. Circulatory diseases include high blood pressure, vascular diseases, heart failure, and cerebrovascular conditions. These conditions make sufferers susceptible to heart attacks, transient chest pain, heart failure, stroke, and sudden death from cardiac arrhythmia. Young children, pregnant women, older adults, and people with respiratory and cardiovascular pre-existing conditions may find that they experience more severe symptoms and find it harder to breathe.3 The full impact of wildfire smoke is not yet fully understood.

How wildfire smoke behaves Many factors affect wildfire smoke behavior, such as: weather geographical terrain the stage of the fire wind Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you. Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the Western United States drifted for nearly 5,000 miles, eventually being detected in Europe. Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the western United States drifted for nearly 5,000 miles, eventually being detected in Europe.6 Wildfire safety tips Wildfire smoke events can occur seemingly without warning. But there are steps you can take to prepare yourself using appropriate safety precautions for wildfires. Keep the air clean in your home. Keep windows and doors closed closed and seal off any openings to the outside, including vents, to help prevent outdoor smoke from getting in. When using an air conditioner, be sure to set it to re-circulate and close the fresh-air intake. Filter the air when ventilating the space. An air purifier for wildfire smoke, will help remove smoke particles of all sizes down to 0.003 microns from the indoor air and help control ozone levels. This is critical if you live in an urban area downwind (even remotely) from wildfires. Stay indoors as much as possible. This tactic is most useful in buildings that effectively stop outdoor air from getting inside. If you need to travel by car to leave or evacuate an area affected by wildfire smoke, use a car air purifier to help keep your vehicle interior air clean as you pass through smoky or polluted areas. You can also use a portable, personal air purifier to access clean air where other air filtration systems are not available. Wear a mask outdoors. Only use an air pollution mask with an N95, KN95, N100, or FFP2 rating to help. Avoid activities that further pollute the indoor air. Avoid burning candles, using the fireplace, or even vacuuming unless you own a high-performance HEPA vacuum cleaner. All of these activities can otherwise become additional sources of indoor air pollutants. Monitor your indoor air quality. Use an air quality monitor to track levels of indoor pollutants like PM2.5 and CO2 from smoke and other indoor pollution sources. Take action if indoor air pollutants rise to dangerous levels by running an air purifier, circulating fresh air through your HVAC system, or leaving your home temporarily if indoor air becomes unsafe to breathe or your home is threatened by wildfire. Use an air quality monitoring app to keep track of pollutants in your environment. The AirVisual app displays real-time hyperlocal data from over 80,000 sensors around the world. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO2, and NO2, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health. Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. Learn to protect the health of yourself and your family, and rest assured that you’ve taken the necessary precautions. During a wildfire, it’s also important to monitor your local air quality to see how wildfire smoke will affect your outdoor air. The takeaway Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. And while wildfire smoke may be a warning sign of imminent fires, smoke also delivers its own set of risks for people living miles beyond the source. Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks. By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.","

Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. Learn to protect the health of yourself and your family, and rest assured that you’ve taken the necessary precautions.

During a wildfire, it’s also important to monitor your local air quality to see how wildfire smoke will affect your outdoor air.

The takeaway

Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. And while wildfire smoke may be a warning sign of imminent fires, smoke also delivers its own set of risks for people living miles beyond the source.

Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks.

By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.

Let's look more critically at air purification.","The home air purifier market has undergone many shifts and starts in its decades-long history as an affordable solution for indoor air quality. Along with those shifts have been seemingly ground breaking advancements in filtration technologies that may seem like the next revolution in air purification. But not all air purifiers safely clean the air. Not all air purifiers safely clean the air. Let's take an evidence-based approach to the industry and separate the fact from the fiction. What should I look for in an air purifier? Before we examine the various air purifiers on the market with a critical eye, it’s essential to have a solid understanding of what does make a good air purifier. 1. HEPA filters are the standard for the industry. What is a HEPA filter? High-efficiency particulate air (HEPA) filters capture airborne particles from moving air using a dense, random arrangement of fibers. HEPA filters use the physics of particles moving through air to yank them out of the air flow. Their operation is simple but extremely effective, and HEPA filters are now standard issue for almost every air purifier on the market. But it wasn’t always that way. Air purifiers have been around for well over a century. The first air purification systems appeared in the 1850s in charcoal-based masks used by coal miners. They were designed to keep toxic dust out of their lungs. The technology was so successful that, less than twenty years later, respirators were added to these types of masks to protect firefighters from breathing in smoke chemicals and pollutants (1). Beginning in the 1940s, the United States Atomic Energy Commission started experimenting with high-efficiency particulate arrestance, better known now as HEPA, as a method of shielding soldiers from atomic radiation on World War II battlefields (2). HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants. In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3). Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns. The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems. Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size. 2. Not all air purifier designs are created equal. All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA. To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4). The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5). So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6). Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less. Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media. 3. Concerned about gas and odors? Go beyond HEPA. While HyperHEPA filters are great at getting particles out of the air, they do NOT take gases and odors out of the air. Unlike particles, the molecules that comprise gases, odors, and volatile organic compounds (VOCs) are not solid and will float through even the densest HyperHEPA filters. That’s where activated carbon filters come in. How do these filters work? It’s simpler than you might think: Chunks of carbon material (like charcoal) are exposed to high concentrations of oxygen. Countless pores open on the carbon surface, increasing the carbon surface area enormously. At this point, a pound of activated carbon can have the same surface area as 100 football fields. Several pounds of activated carbon are arranged in a flat “bed” and packaged in a proprietary filter design (such as IQAir’s V5 Cell gas and odor control filter). Air passes through the activated carbon bed. Gas, chemical, and VOC molecules are adsorbed into the carbon pores, meaning that they chemically bond to the extensive charcoal surface area. Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes (7)(8). Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes. Some air purifiers are designed to maximize activated carbon in case you’re more concerned about, for example, gases from cooking or odors from pets than about particle pollution in your home. IQAir’s GC MultiGas is built for such a purpose—while carbon filters generally use a few pounds of carbon, the GC MultiGas contains 12 pounds of activated carbon as well as impregnated alumina, providing well over 1200 football fields worth of surface area for gas and VOC molecules to adsorb to. The takeaway Now you know that the elements of a good air purifier are: HyperHEPA media for particle filtration No system leakage due to sealed filter and purifier housing Activated carbon for gas and odor filtration But we're not done yet. Just as important to know is what not to look for in an air purifier. What should I avoid in an air purifier? When considering air purifiers, some people wonder about their effectiveness and even potential risks. Question often arise, such as \"Do air purifiers work?\" or \"Are air purifiers effective?\" The answer is that while some air cleaning methods can remove particles and pollutants from the air, their capabilities are often limited. But it's not just about effectiveness. People also ask, \"Are air purifiers bad for you?\" This concern arises from potential hidden costs to your health. It's important to be aware of inefficiencies and any potential risks associated with the air purifier you're considering before making a purchase. So, if you're in the market for an air purifier, remember to ask yourself whether it will be effective at removing pollutants and particles from the air, and whether it poses any risks to your health. Ionizer air purifiers Ionizers are purported to purify air by sending out negatively charged ions (anions) that attract positively charged pollution particles (cations), causing them to leave the air and stick to surfaces like ceilings, walls, and furniture. Many popular air purifiers use ionization technology, also called negative ionization, as a central component of their operation. Research suggests that ionizers can help stop potentially infectious molds and bacteria from spreading in sterile environments like dental clinics and hospitals (9)(10). But there are two critical downsides to ionization (11)(12): Ionizer air purifiersdon’t get rid of pollutants. Particles charged by negative ions aren’t removed from the air—they merely stick to surfaces nearby. This includes surfaces inside your airways, such as your windpipe and alveoli, the sacs of air in your lungs. Pollutant build-up can cause heart, lung, and other respiratory conditions. Ionizer air purifierscan generate harmful ozone. Ionizers produce ozone (O3) that can build up to dangerous levels indoors. At even low levels, indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb (the organ that helps your brain process odors), and even be fatal at high concentrations. Indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb, and even be fatal at high concentrations. Verdict Don't buy an ionizer air purifier.They don’t remove particles from the air, and the ozone they produce can have harmful side effects, even if the purifier claims that they only charge the particles “a little bit.” Ozone Generators It’s worth saying again: ozone is TERRIBLE for you, especially indoor ozone build-up. The health concerns are serious enough that in 2017, California banned the use of ozonehome air purifiers (13). Ozone generators use a process called corona discharge to release ozone molecules into the air. When an ozone molecule intermingles with a particle or gas molecule, an ozone atom clings to the other molecule and blows it up in a process known as oxidation. Oxidation in the atmosphere after a lightning strike is also what makes the air smell so distinct after a thunderstorm. However, ozone generators do little to clean air and are quite bad for you. Here’s just a short (and far from complete) list of reasons why (14)(15)(16)(17)(18): Ozone can take years to fully clear even a small room of gases. Ozone reactions can introduce ultrafine particles (UFPs) into the air.UFPs can get into your lungs and your bloodstream, causing heart disease and even stunting lung development in children. Indoor ozone levels can rise five to ten times above recommended limits,which range from 0.05 to 0.1 parts per million (ppm), because of a lack of ventilation and in combination with outdoor ozone that seeps indoors.To put this in perspective, those who are sensitive to ozone, such as children, people with asthma, and pets, start experiencing health effects at only 0.01 ppm. Even a “safe” ozone generator that emits a small amount of ozone can quickly trigger potentially life-threatening ailments like asthma attacks. Verdict Don’t buy an ozone generator. They’re NOT air purifiers. Not only do they fail to clean your air, they hurt you and the most vulnerable in your home: your children and your pets. UV Light Purifiers Ultraviolet (UV) light is often used to disinfect equipment in hospitals and prevent the spread of harmful strains of bacteria and viruses (19)(20). One of the most common UV purification methods is called ultraviolet germicidal irradiation, or UVGI. In UVGI, intense UV lights are shined on bacteria and viruses, damaging their DNA beyond repair. Bacterial cells and viruses then shut themselves down because they can no longer function. This is called apoptosis, or programmed cell death, which effectively destroys their ability to cause infections (21). But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26): Bacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful. Some bacteria can come back to life and become infectious again even after being disinfected by UV light. UV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5. Many UV air purifiers produce ozone. UV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer. Air treated with UV light can still be full of harmful particulate matter. Verdict Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated. What do I do now? At this point, you should feel like you have a good sense of what’s fact and what’s fiction when it comes to a truly effective air purification system.

Himalayan salt lamps DO NOT purify indoor air.

These trendy little lamps consist of a light bulb placed inside a chunk of pink Himalayan salt. They’re easily recognized by their hand-carved, often stylized shapes and dim, pinkish glow they emit when light shines through them.

They’ve been gaining popularity for years, mostly because their distinct color and unique appearance make them attractive objects for interior decoration, and their glow can add a pleasing atmosphere to a room.

But their recent rise in popularity as “natural” air purifiers should trouble you.

A host of (often misleading) studies supporting the use of salt in treating respiratory conditions have escalated demand for these little pink things, especially within the well-primed alternative medicine market, full of people who may already be seeking home remedies for all sorts of health conditions and indoor environmental issues when modern medicine hasn’t seemed to help.

And you shouldn’t buy a Himalayan salt lamp to purify your air for one major reason: they’re negative ionizers, and negative ionization is one of the most absurd air purification myths ever devised.

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

If you ever hear the words “ionization” (in one form or another) and “air purification” in the same sentence, you should run in the opposite direction.

In the context of air purification, negative ionization happens when negatively charged particles attach themselves, or “charge,” pollutant particles in the air, effectively removing them from ambient air by causing them to stick to nearby surfaces.

This phenomenon also occurs in nature – know that distinct smell in the air after a thunderstorm? That’s the result of “atmospheric space charge” as air ions are generated by the electric fields of storms.¹ Many air purifiers and purification devices sold in stores, including Himalayan salt lamps and a variety of “air ionizers,” artificially produce high voltage to achieve this same effect.

The problem with negative ionization, though, is that it doesn’t actually remove pollutants from your indoor air – it just causes the particles to adhere themselves to nearby surfaces, where they’re easily stirred up by indoor activities like dusting, vacuuming, and ventilation.

Charged particles can also stick to your respiratory tract, where charged particles can settle in your windpipe and lungs and cause even more harm that if they’d just remained in the air. Studies show that these particles can penetrate deep into your respiratory system and cause both heart and lung conditions.²

The average, nightstand-sized Himalayan salt lamp generates only a small number of negative ions into the air, so you may not notice any tangible change in your air quality or health, at least immediately. But these lamps can be huge: you can buy salt lamps that weight up to 300 pounds for thousands of dollars, and their ionization effects may have a more noticeable effect on your air, especially if you live in an airtight, energy-efficient home in which indoor pollutants have a much harder time getting out.

And negative ionizers have another dark secret: they can also create indoor ozone (O₃).

There are two main types of ozone:

\nStratospheric ozone: Alayer of ozone occurs naturally several miles up in the atmosphere, where it protects the surface of the earth (and people’s skin) from ultraviolet (UV) radiation from the sun.
\nTropospheric ozone: Also called ground-level ozone or smog, ground-level ozone tends to develop when heat from sunlight reacts with chemicals near the ground, many of which are produced by emissions from vehicle exhaust and factory smoke.

Negative ionization can generate tropospheric ozone indoors. While stratospheric ozone has no interaction with us in the lower atmosphere, ground-level ozone is far more harmful when it builds up to high levels. And perhaps one of the starkest examples of ground-level ozone is one that millions of us know very well – the smog that forms in major cities during rush hour.

If you live near a freeway, dense urban center, or even at a high elevation where you can see the area around an urban area. A few hours or less after rush hour begins and the sun begins to rise, you’ll start to notice a visible layer of haze build up. This is ground-level ozone, and even though it’s a typical feature of modern life, extensive research shows that it causes a plethora of immediate symptoms, including:

Coughing
Wheezing
Trouble breathing
Stuffy nose
Dizziness
Tingling in arms and legs
Fever^3,4\n

Further research suggests that ozone is also responsible for long-term health problems, such as asthma, heart disease, and lung disease. Emerging studies on rats also suggest that ozone could cause seizures and blindness.

So even though you may not get rush-hour levels of ozone in your home from a salt lamp, indoor ozone buildup can indeed cause some disruptive health effects if you don’t follow best practices for good Indoor Air Quality.

So what’s so special about Himalayan salt?

So how did someone come up with the idea that Himalayan salt lamps have any health effects at all?

The story stretches back millennia. Truly authentic Himalayan salt comes from the Khewra salt reserves in the Punjab region of Pakistan. Salt mined here is thought to be millions of years old and contain numerous minerals.

Salt lamps have been proposed for use in treatments for conditions like chronic obstructive pulmonary disease (COPD) because of their purported therapeutic effects on your respiratory system. This treatment even has a clinical term: halotherapy, based on an ages-old respiratory treatment technique known as speleotherapy. First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:⁵

Stable air temperature
Moderate to high humidity
Presence of aerosol elements, such as sodium, potassium, and magnesium
Lack of airborne pollutants

Halotherapy takes the notion that salt cave environments are good for respiratory health by having people inhale small amounts of salt particles that are released into the ambient air of a controlled room to “reproduce” a salt cave’s microclimate. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.⁶

Take the claims with a grain of...well, salt

So here’s the takeaway: We’re not saying you shouldn’t get a Himalayan salt lamp. Their dim glow can be quite soothing at night when you’re trying to fall asleep.

But they don’t purify air. And “air purifiers” that emits ions and ozone may make your indoor air quality worse, introduce new health problems, and exacerbate existing ones.

Are scented candles bad for you?

Burning a scented candle is a popular way to create a pleasant ambiance at home. Scents such aslavender, jasmine, and sandalwood can be relaxing and invigorating. During the holidays, many people find the warm glow and aroma of pine, gingerbread, or cinnamon makes a room feel more festive.

Unfortunately, most mass-produced scented candles can have a negative impact on indoor air quality. From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

So while you and your family may enjoy the fragrance of scented candles in your home, they may be harmful to your health. Read on to learn why some candles are bad for you.

Paraffin wax

Are paraffin wax candles safe? In what way can wax be harmful?

According to a 2017 study in the International Journal of Tropical Disease and Health, paraffin candles emit pollutants that can threaten human health and shouldn’t be burned in enclosed areas (1).

Most candles are made from paraffin, a petroleum byproduct. To create paraffin wax candles, petroleum waste is chemically bleached, deodorized, and made into wax. When burned, paraffin wax can release toxicvolatile organic compounds (VOCs) into the air, including known carcinogens like:

alkenes
acetone
benzene
toluene

These are the same chemicals found in diesel fuel emissions and are known to cause allergies, asthma attacks, and skin problems.

A 2005 study published by the University of South Florida showed that candles made of paraffin wax emit low levels of benzene even when they are not lit (2).

Is burning candles bad for you?

In addition to releasing toxic chemicals, burning paraffin wax produces soot composed of particulate matter such as, PM2.5 and ultrafine particles that can remain suspended in the air for hours. According to the University of South Florida study, ultrafine soot particles are similar to diesel exhaust in both their size and composition. They penetrate deeply into the lungs and are absorbed into the blood stream (3).

A 2000 study conducted by the U.S. Environmental Protection Agency showed that soot emissions from candles are significantly higher after wax breakthrough occurs and when a candle is smoldering (4).

Ultrafine particles are associated with severe health issues, including:

allergies
asthma
COPD (5)
respiratory tract infections
heart attacks
strokes
cancer

So, are candles bad for your health? Not all candles produce the same amount of air pollutants. A 2002 study published in theJournal of the American Oil Chemists’ Society found that soywax, much like beeswax candles, burned at a significantly lower rate and resulted in less soot than paraffin candles (6).

Chemical fragrances

Another problem with scented candles is that the chemicals they use to create a pleasing aroma are generally far from wholesome.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature. Commonly emitted VOCs related to the scent in candles include (7):

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

headaches
dizziness
allergy symptoms
asthma attacks
respiratory tract infections
cancer
\n\n\t

Cored wicks

Many candles have cored wicks made from cotton that are wrapped around a metal support. The design helps keep the wick from falling over into the wax. This is especially useful for scented candles because the fragrance oils soften the wax and allow non-cored wicks to go limp.

Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas.

Zinc and tin have been used as a substitute since the ban.

All metal-core wicks release trace amounts of heavy metals into the air when they are burned.

However, all metal-core wicks release trace amounts of heavy metals into the air when they are burned. Wicks with zinc and tin cores can still release small amounts of lead particles (9,10).

Safer alternatives

To limit soot stains and poor air quality in your home, you should avoid or restrict the use of candles (11).

If you still crave the pleasant ambiance and aroma of scented candles, here are safer ways to scent the air:

\nUse essential oils for fragrance.Essential oils can be placed in a diffuser or in bathwater to create a desired aroma.
\nSimmer spices.Place spices such as cinnamon sticks, cloves, and nutmeg in a pot of water and let it simmer on the stove.
\nCreate potpourri.Dried items such as flowers, berries, fruit rinds, wood chips, and spices can be placed in bowls or fabric bags and placed around your home.

The takeaway

Lighting scented candles may seem like a relaxing way to enjoy your home. But burning scented candles releases VOC pollutants and worsens your home’s indoor air quality. Although fragrances from safer alternatives like essential oils can be pleasant, trulyclean air smells like nothing at all.

Discover how Tedy Mwendwa's air quality monitoring project in Nairobi is bridging critical gaps in Africa's air quality data. Learn more.

","“Every day, I witness the severe impact of poor air quality on my community,” Tedy Mwendwa explained. “Using my expertise in electrical engineering, I felt compelled to create change.” In the heart of Africa, amidst bustling cities and vibrant rural landscapes, Mwendwa is pioneering a movement for cleaner air in Kenya. With a professional foundation in electrical engineering and a passion for environmental stewardship, Mwendwa's deployment of a low-cost air quality sensor in Kenya’s capital city, Nairobi, marks a pivotal step in revealing and addressing pollution and bridging critical gaps in Africa’s air quality data. Nairobi's leap towards cleaner air In late 2021, Mwendwa established an air quality station. Set up along one of Nairobi’s busy thoroughfares, the station gathers data on pollutants from sources like vehicular exhaust and biomass burning. \"It's about leveraging technology to unveil the hidden dangers of pollution.” “It's about leveraging technology to unveil the hidden dangers of pollution,” Mwendwa said. “Empowering our community with this data is crucial for driving action and advocating for sustainable solutions. Without data, we remain in the dark.” Local expertise, global resources drive innovation Building on the foundation of community-driven air monitoring, the project has taken a step forward. It now hosts East Africa’s first Monster Aerosol System (a platform that houses advanced aerosol analyzers), featuring a Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM). This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—uncovering the chemical fingerprints of pollution with unprecedented precision. Paired with a black carbon monitor, the system offers a comprehensive view of airborne composition and sources. These reference-grade instruments build on the project’s original IQAir AirVisual Outdoor monitor—pairing community-level, real-time data with laboratory-grade chemical insight. The TOF-ACSM will help identify pollution sources—from mineral dust kicked up by unpaved roads and construction to organic aerosols tied to biomass burning and traffic emissions. It will also track seasonal and daily shifts in air quality, influenced by weather patterns and human activity.

“Every day, I witness the severe impact of poor air quality on my community,” Tedy Mwendwa explained. “Using my expertise in electrical engineering, I felt compelled to create change.”

In the heart of Africa, amidst bustling cities and vibrant rural landscapes, Mwendwa is pioneering a movement for cleaner air in Kenya. With a professional foundation in electrical engineering and a passion for environmental stewardship, Mwendwa's deployment of a low-cost air quality sensor in Kenya’s capital city, Nairobi, marks a pivotal step in revealing and addressing pollution and bridging critical gaps in Africa’s air quality data.

Nairobi's leap towards cleaner air

In late 2021, Mwendwa established an air quality station. Set up along one of Nairobi’s busy thoroughfares, the station gathers data on pollutants from sources like vehicular exhaust and biomass burning.

\"It's about leveraging technology to unveil the hidden dangers of pollution.”

“It's about leveraging technology to unveil the hidden dangers of pollution,” Mwendwa said. “Empowering our community with this data is crucial for driving action and advocating for sustainable solutions. Without data, we remain in the dark.”

Local expertise, global resources drive innovation

Building on the foundation of community-driven air monitoring, the project has taken a step forward. It now hosts East Africa’s first Monster Aerosol System (a platform that houses advanced aerosol analyzers), featuring a Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM). This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—uncovering the chemical fingerprints of pollution with unprecedented precision. Paired with a black carbon monitor, the system offers a comprehensive view of airborne composition and sources. These reference-grade instruments build on the project’s original IQAir AirVisual Outdoor monitor—pairing community-level, real-time data with laboratory-grade chemical insight.

The TOF-ACSM will help identify pollution sources—from mineral dust kicked up by unpaved roads and construction to organic aerosols tied to biomass burning and traffic emissions. It will also track seasonal and daily shifts in air quality, influenced by weather patterns and human activity.

WWF Pakistan is tackling air pollution with IQAir. Learn how real-time data is driving change across the country.

","In Pakistan, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of air quality data, air quality monitors, and public awareness, the scale of the threat remains largely unseen. In 2024, Pakistan was the third most polluted country in the world, with an average PM2.5 concentration of 73.7 μg/m3 and exceeding the World Health Organization’s recommended annual guideline of 5 μg/m3 by 14.7 times. Numerous cities experienced poor air quality, with high average PM2.5 concentrations measured for Islamabad (52.4 μg/m3), Rawalpindi (65.8 μg/m3), Faisalabad (88.8 μg/m3), Peshawar (91.0 μg/m3), and Lahore (102.1 μg/m3) – all exceeding the WHO recommended guideline by ten times or more. Recognizing the urgency of this crisis, WWF-Pakistan has taken significant steps to address air pollution using IQAir’s air quality monitoring technology. WWF-Pakistan has successfully deployed stations across Pakistan and published data to IQAir’s AirVisual platform, establishing the country’s largest air quality monitoring network. With this initiative, WWF-Pakistan is transforming how the country understands and confronts this invisible threat. \"We have successfully reached the goal of installing AirVisual Outdoor sensors in 15 of our offices across Pakistan,\" said WWF-Pakistan’s Research Officer, Muhammad Huzaifa who led this initiative in Pakistan. As of now, WWF-Pakistan has air monitoring stations located in key regions like Karachi, Lahore, Quetta, Multan, and Peshawar. They provide real-time data that is accessible to both policymakers and the public. \"We are excited to say that we’ve published the data from these stations to IQAir’s platform, where communities can see their local air quality in real-time.” Why Pakistan Needs Reliable Air Quality Data Pakistan's urban centers, such as Lahore, Peshawar and Karachi, frequently grapple with thick layers of smog. While this is a visible reminder of air pollution, the more dangerous pollutants often remain unseen and unmonitored. One of the greatest challenges in Pakistan has been the need for more reliable, public air quality data. \"Our air quality network provides crucial air quality data in some of Pakistan’s most polluted regions and are often ranked among the top 10 most polluted cities in the world\" Huzaifa explained. WWF-Pakistan, the nation’s largest environmental organization, has been addressing critical environmental issues since 1970. Originally focused on protecting wildlife and ecosystems, the organization’s scope has broadened to include tackling climate change, protecting vulnerable habitats, and securing vital resources like freshwater. Now, through their air quality monitoring initiative, they are addressing one of the most pressing health and environmental crises facing Pakistan. “Unfortunately, there is little public air quality data available,” Huzaifa noted. “This information vacuum has left policymakers and citizens unprepared to tackle the pollution crisis.” WWF-Pakistan’s initiative helps fill this gap, ensuring the public has access to real-time, localized air quality data. With real-time data now available, citizens, governments, and policymakers can work together to implement solutions, reduce pollution and improve health outcomes across the country. Building Pakistan's National Air Quality Network WWF-Pakistan’s initiative, which involves installing air quality sensors in key cities across the country, marks a critical step in Pakistan’s battle against air pollution.

A vision born from necessity Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted. Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air. “There’s a significant data gap in Africa when it comes to understanding our air.” –Dr. Sunkaru Touray, Founder, Permian Health The journey of Permian Health Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside. \"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\" Highlighting areas of concern: Brikama’s air quality Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions. Dr. Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.” “The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.” Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March. Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data. Pioneering work on the ground To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia. \"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\" This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said. However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues. ‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained. Uniting minds and garnering accolades To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project. A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data. \"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray. This national conversation is already making a policy impact. The Ministry of Health has issued public health advisories several times since the air quality sensors were deployed, raising air quality awareness in communities around the country. Dr. Touray emphasizes the importance of partnering with the Gambian government to leverage their data for national air quality standards and planning. \"Working closely with governmental bodies is crucial for our success,\" Dr. Touray notes, highlighting his strong connections within the National Environment Agency, which have been supportive of their endeavors. With the NEA, Permian Health was able to release their first air quality report based on initial installations. This sets the table for future updates from newly installed sensors. Additionally, the project's recent recognition by the Energy Policy Institute of the University of Chicago with an Air Quality Award underscores the global acknowledgment of their impactful work. This prestigious award will enable Permian Health to scale their network further. Currently, there are 22 low-cost sensors deployed, and Gambia will, for the first time ever, have a reference monitor to assist in enhancing air quality monitoring and assessment. Hopes for the Future Thanks to their recent Air Quality award, Permian Health acquired an additional 10 sensors, bringing the total to 26 sensors across The Gambia. Six new sensors have been deployed to NEA headquarters, two major health centers with support from the Ministry of Health, and in housing developments in partnership with Gambia’s largest real estate company, TAF Africa Global. The remaining sensors will be deployed to the National Stadium, Gambia International Airport, the Seaport in Banjul, and a major intersection as soon as final government approvals are processed. Dr. Touray envisions a future where every Gambian has access to air quality information, enabling them to protect themselves and their families from air pollution.

In the slender West African nation of Gambia, Dr. Sunkaru Touray of Permian Health Lung Institute is leading an unprecedented initiative to illuminate the invisible dangers of air pollution through the strategic deployment of low-cost air quality monitors.

A vision born from necessity

Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted.

Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air.

The journey of Permian Health

Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside.

\"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\"

Highlighting areas of concern: Brikama’s air quality

Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions.

$\"\"$

Dr. Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.”

\n
“The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.”
\n

Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March.

Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data.

Pioneering work on the ground

To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia. \"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\"

This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said.

However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues.

‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained.

Uniting minds and garnering accolades

To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project.

A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data.

\"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray.

This national conversation is already making a policy impact. The Ministry of Health has issued public health advisories several times since the air quality sensors were deployed, raising air quality awareness in communities around the country.

Dr. Touray emphasizes the importance of partnering with the Gambian government to leverage their data for national air quality standards and planning. \"Working closely with governmental bodies is crucial for our success,\" Dr. Touray notes, highlighting his strong connections within the National Environment Agency, which have been supportive of their endeavors.

With the NEA, Permian Health was able to release their first air quality report based on initial installations. This sets the table for future updates from newly installed sensors.

Additionally, the project's recent recognition by the Energy Policy Institute of the University of Chicago with an Air Quality Award underscores the global acknowledgment of their impactful work. This prestigious award will enable Permian Health to scale their network further.

Currently, there are 22 low-cost sensors deployed, and Gambia will, for the first time ever, have a reference monitor to assist in enhancing air quality monitoring and assessment.

Hopes for the Future

Thanks to their recent Air Quality award, Permian Health acquired an additional 10 sensors, bringing the total to 26 sensors across The Gambia.

$\"\"$

Six new sensors have been deployed to NEA headquarters, two major health centers with support from the Ministry of Health, and in housing developments in partnership with Gambia’s largest real estate company, TAF Africa Global. The remaining sensors will be deployed to the National Stadium, Gambia International Airport, the Seaport in Banjul, and a major intersection as soon as final government approvals are processed.

Dr. Touray envisions a future where every Gambian has access to air quality information, enabling them to protect themselves and their families from air pollution. Furthermore, he hopes to leverage the data collected to advocate for stronger environmental policies and regulations in Gambia.
