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.

Indoor cooking smoke is a major source of household air pollution that disproportionately affects women’s health. Learn why—and what solutions can reduce exposure.

","Indoor cooking smoke is a leading source of household air pollution, affecting billions of people worldwide. In many parts of the world, women are most often responsible for preparing meals, placing them at the center of this exposure and at the greatest risk from prolonged contact with smoke produced by solid fuels and inefficient stoves. Every day, more than 2.1 billion people—primarily in low- and middle-income countries—rely on open fires or rudimentary stoves to cook their food (1). The smoke generated during cooking does not simply dissipate when the meal is finished; it often lingers in enclosed spaces, extending exposure beyond the cooking period itself. As a result, women and children experience the heaviest health burden from household air pollution. Many spend hours each day in poorly ventilated kitchens, breathing in high concentrations of smoke that contribute to respiratory disease, pregnancy complications, and long-term health risks. While the burden is greatest in regions that rely heavily on solid fuels, research increasingly shows that cooking-related air pollution can also affect women in higher-income countries—particularly in homes and workplaces where combustion or high-temperature cooking is common. The health risks of cooking smoke exposure Cooking smoke is not a single pollutant, but a concentrated mix of fine particles and harmful gases produced when solid fuels are burned indoors. When exposure occurs daily and over long periods—as it does for many women—the health consequences can be severe and cumulative. Exposure to PM2.5 and carbon monoxide greatly increases the risk of chronic obstructive pulmonary disease (COPD), lung cancer, and asthma (1). According to a study published in BMJ Open Respiratory Research, women in households using biomass fuels are 1.38 times more likely to develop COPD than those using cleaner energy sources (2). Indoor air pollution is also a major contributor to heart disease and stroke, as inhaling toxic fumes accelerates atherosclerosis and raises blood pressure. Research indicates that cooking smoke exposure may also affect mental health. A survey of women who were the main household cooks in Kenya, Cameroon, and Ghana found higher rates of depression among those using charcoal or wood, as well as poorer mental well-being among women who spent more time cooking each week. (3). Pregnant women are especially vulnerable, as air pollution has been linked to maternal hypertensive disorders, placental abruption, preterm birth, low birth weight, infant mortality, adverse lung and respiratory effects, and postpartum depression (5). And because women are typically responsible for cooking even when other household members are present, this exposure often continues daily and across life stages—reinforcing a pattern of risk that can span generations (4). This persistent exposure raises an important question: why are women more likely to experience cooking smoke in the first place? Why women face higher exposure to cooking smoke Women face the greatest health impacts from indoor cooking smoke due to deeply rooted gender roles and, in some cases, differences in biological susceptibility. Some studies suggest women may experience different biological responses to air pollution, increasing vulnerability to chronic respiratory disease (5). In many cultures, women are responsible for cooking, spending hours each day in cramped, poorly ventilated spaces. This prolonged exposure elevates their intake of fine particulate matter, or PM2.5 — particulate matter measuring 2.5 microns in diameter or smaller. Exposure is especially high in households that rely on biomass or kerosene, where cooking often takes longer and produces heavier smoke, increasing both the duration and intensity of daily exposure. Is cooking smoke bad for pregnancy? Exposure to cooking smoke has been linked to low birth weight, as pollutants cross the placental barrier and impair fetal development (6). Emerging research also suggests a connection between indoor air pollution and cervical cancer (7). Cooking smoke may contribute to serious pregnancy-related complications. A multi-country study led by researchers at King’s College London found a significant association between household exposure to smoke from solid-fuel cooking and increased rates of eclampsia—a life-threatening condition characterized by severe hypertension and seizures during pregnancy. The risk was highest in households using wood or charcoal and where kitchen ventilation was poor, underscoring how both fuel type and airflow influence maternal health outcomes (8). Evidence also points to impacts beyond physical health. A large population-based study in China found that maternal exposure to cooking smoke during pregnancy was associated with a markedly higher risk of hyperactivity behaviors in children by age three. The risk increased with more frequent cooking and was higher in households using coal or gas compared to electricity, particularly where kitchen ventilation was poor. These findings suggest that indoor cooking smoke may affect early neurodevelopment, extending the health burden across generations (9). Where indoor cooking smoke remains most common The health impacts of indoor cooking smoke are most severe in regions where solid fuels remain the primary source of household energy. Cooking smoke has a disproportionate impact on women in rural and low-income communities across sub-Saharan Africa, South Asia, and parts of Latin America, where reliance on solid fuels like wood, charcoal, and dung remains widespread. Sub-Saharan AfricaIn sub-Saharan Africa, women in rural areas often cook over open fires in enclosed spaces, leading to chronic exposure that contributes to an estimated half a million premature deaths each year (10). In Ethiopia, biomass fuel makes up 95% of total primary energy consumption; household air pollution in Ethiopia has also been tied to 67,830 annual deaths (11). Over 175 million Nigerians burn biomass for cooking; over 128,000 preventable deaths in 2019 have been ascribed to indoor air pollution and biomass burning (12). South AsiaSouth Asia faces similar challenges, particularly in India, Bangladesh, and Nepal (13) (14). According to a study conducted in Southern Nepal, the median daily average PM2.5 concentration for people cooking with traditional cookstoves was 66.7 times higher than the 2021 WHO guideline for daily exposure of 15 μg/m3 (15). India’s Ujjwala Yojana program has provided millions of rural households with LPG connections while reducing dependence on firewood, cow-dung, coal, crop residue, and kerosene as cooking solutions (16). Latin AmericaIn Latin America, where clean energy adoption has improved, rural communities in Brazil, Mexico, and Central America continue to struggle with indoor air pollution. Open fires and traditional fuels are relied upon daily by 12% of the population of Latin America (17). However, residential firewood use has declined in the past two decades. Firewood accounted for 43% of household energy fuel in 2004 and dropped to 31% by 2024. North America and EuropeIn the United States, a large cohort study found that frequent indoor wood burning from fireplaces and stoves was associated with a higher risk of lung cancer among women, even among never-smokers (18). Importantly, this increased risk was observed in both urban and rural settings, highlighting that indoor combustion sources can pose health risks regardless of geography. Broader evidence from Western countries reinforces these findings. A systematic review of studies conducted across Europe, Canada, the United States, Australia, and New Zealand identified a strong association between indoor solid fuel exposure and chronic obstructive pulmonary disease (COPD) (19). The review also noted elevated risks of respiratory issues linked to residential coal and wood burning. Cooking smoke exposure beyond its most common settings Although indoor cooking smoke is most often discussed in the context of solid-fuel use, similar exposure pathways exist in many modern environments—where enclosed kitchens, combustion sources, and high-temperature cooking can still generate harmful air pollutants. Occupational exposure in professional kitchens Women working in professional kitchens face additional risks due to prolonged exposure to cooking fumes. High-temperature frying and grilling release carcinogenic and mutagenic compounds, including polycyclic aromatic hydrocarbons. Studies from Norway have shown that cooks and kitchen workers experience higher rates of respiratory distress, reduced lung function, and increased mortality from airway diseases (20). Similar concerns have been documented elsewhere. Research in South Korea found that female school cooks and kitchen clerks were at elevated risk for lung cancer associated with cooking fume exposure. (21). A meta-analysis of case-control studies spanning Europe, Canada, New Zealand, and China further concluded that women working as cooks may face a higher lung cancer risk independent of tobacco use. (22).Together, these findings show that cooking-related air pollution is not confined to traditional or biomass-fueled settings. Across homes and professional kitchens alike, prolonged exposure to cooking smoke—especially in enclosed spaces—can pose significant health risks for women worldwide. Mitigation and protection strategies The most effective way to reduce women’s exposure to indoor cooking smoke is by transitioning to cleaner fuels and improved stove designs, supported by adequate ventilation—principles that apply across both household and professional cooking environments. Cleaner energy sources—such as electricity or solar—dramatically reduce the amount of harmful particulate matter and toxic gases released during cooking. Modern, efficient cookstoves further limit emissions while improving safety and fuel efficiency. However, because access to clean fuels and modern stoves remains uneven, interim measures can still help lower exposure. Improving ventilation—through chimneys, strategically opened windows, exhaust hoods—can help direct smoke away from living spaces. Where feasible, wearing a properly-fitted KN95/FFP2 mask during cooking can reduce inhalation of biofuel pollutants. Cooking outdoors when weather permits can also significantly reduce indoor air pollution. Encouragingly, large-scale interventions show that progress is possible. In Rwanda, the government launched the Energy Access and Quality Improvement Project to reduce reliance on firewood and charcoal in favor of cleaner cooking fuels and improved cookstoves. Beyond health benefits, the program has helped reduce pressure on forests, cut the time women spend gathering fuel, and create local jobs through the distribution and installation of cleaner cooking solutions across the country (23). Conclusion Indoor cooking smoke is a preventable health risk that harms women worldwide, contributing to millions of premature deaths each year. The solution lies in scalable interventions: cleaner fuels, improved stove designs, and better ventilation. With so many people still reliant on inefficient stoves and open fires, challenges will remain. Bridging this gap will depend on sustained policy action, investment, and global cooperation to expand access to clean cooking solutions.","

Indoor cooking smoke is a leading source of household air pollution, affecting billions of people worldwide. In many parts of the world, women are most often responsible for preparing meals, placing them at the center of this exposure and at the greatest risk from prolonged contact with smoke produced by solid fuels and inefficient stoves.

Every day, more than 2.1 billion people—primarily in low- and middle-income countries—rely on open fires or rudimentary stoves to cook their food (1). The smoke generated during cooking does not simply dissipate when the meal is finished; it often lingers in enclosed spaces, extending exposure beyond the cooking period itself.

As a result, women and children experience the heaviest health burden from household air pollution. Many spend hours each day in poorly ventilated kitchens, breathing in high concentrations of smoke that contribute to respiratory disease, pregnancy complications, and long-term health risks.

While the burden is greatest in regions that rely heavily on solid fuels, research increasingly shows that cooking-related air pollution can also affect women in higher-income countries—particularly in homes and workplaces where combustion or high-temperature cooking is common.

Learn about University of Cape Coast’s wide-reaching air quality network in Ghana

","Across Ghana, everyday activities—gold mining, grain milling, open-air work in mechanic yards, and congested transport hubs—regularly elevate pollution. Yet the communities closest to these pollution sources often lack consistent, site-level monitoring that can inform and help them understand their exposure. Physicist and lecturer Dr. Christiana Odumah is addressing this gap with her University of Cape Coast team, using IQAir AirVisual Outdoor monitors to track pollution levels and communicating the results to change daily practices on the ground. Choosing a path forward Dr. Odumah’s journey began in physics, researching contaminant transport in the atmosphere, especially mercury. Now at the University of Cape Coast, she teaches Air Pollution & Emission Control and Air Quality Management, and leads a field program that measures exposure, sharing practical guidance with communities and policymakers. “Air pollution is a serious issue, and we all need to work on it,” Dr. Odumah said. “When the air is polluted, before you can even say where it came from, it has already traveled to other people.” Building a monitoring network The team needed monitors that could handle harsh conditions and require minimal maintenance. They selected IQAir AirVisual Outdoor monitors as the backbone of the network. “They’re rugged enough for heat and dust, straightforward to deploy, and it’s easy to share our data publicly,” Dr. Odumah said. The University of Cape Coast’s network covers high-exposure settings across Ghana and publishes live to IQAir’s air quality platform. Stations include: Gold-mining communities — valley towns near active mining operations, where cooler, still air can trap pollution overnight. Mechanic workshops — open-air spray painting, welding, and grinding that impact daytime pollution spikes. Campus & transport hubs — taxi stands and arterial roads with predictable rush-hour peaks. Neighborhood milling centers — locally built grain and cassava mills that vent outdoors. Each site acts as both a data point and a conversation starter—not only coming together to paint a fuller picture of the air quality across Ghana but helping communities see, in the data, the pollution they experience—so they can act on it. Turning data into decisions Real-time, new-found visibility into the air quality is changing routines. The team analyzes pollution trends across the station locations, using the AirVisual Platform, to recommend low-cost, high-impact habits—from establishing simple personal protective equipment (PPE) norms and guidelines to regular road wetting near mine haul routes. “The platform includes particle pollution, temperature, pressure, humidity, and downloading the data is straightforward,” says Dr. Odumah, noting too that the platform makes trend analysis easier, enabling the team to provide practical guidance. “When the air is polluted, before you can even say where it came from, it has already traveled to other people.”—Dr. Christiana Odumah, University of Cape Coast Education and empowerment The air quality monitors double as teaching tools. In lectures and informal workshops, Dr. Odumah’s team walks through what PM2.5 is, why some places experience worse elevated levels at certain times, and how small choices—mask use, ventilation, timing—compound into real protection and health benefits. Students help maintain stations and interpret patterns, building local capacity for work that will last beyond this specific project. Looking ahead The path forward combines academic rigor and reach. Dr. Odumah explained that two publications are fully drafted and a third is almost complete. “We’re hoping to submit three papers by year-end,” she said. Next, the team plans to broaden the network and provide actionable playbooks for millers, mechanics, schools, and local authorities. Trials with secondary-pollutant sensors are planned to complement the insights already gathered. And in Tarkwa, a station will be kept in place to serve the community long-term. Dr. Odumah said: “They need constant monitoring, even if it means I can’t redeploy that unit for research.” Conclusion Air pollution is often invisible—but its effects are not. By putting monitors where people live and work, Dr. Christiana Odumah’s team is helping communities turn numbers into know-how—and know-how into healthier habits. The model is simple and scalable: measure what matters, share it widely, and act together to bring clean air to the community. As Dr. Odumah said, “If people realize their health is at risk, they’ll find ways to cut emissions. That’s why we need this monitoring—so the community can act.”","

Dr. Odumah’s journey began in physics, researching contaminant transport in the atmosphere, especially mercury. Now at the University of Cape Coast, she teaches Air Pollution & Emission Control and Air Quality Management, and leads a field program that measures exposure, sharing practical guidance with communities and policymakers.

“Air pollution is a serious issue, and we all need to work on it,” Dr. Odumah said. “When the air is polluted, before you can even say where it came from, it has already traveled to other people.”

Building a monitoring network

The team needed monitors that could handle harsh conditions and require minimal maintenance. They selected IQAir AirVisual Outdoor monitors as the backbone of the network. “They’re rugged enough for heat and dust, straightforward to deploy, and it’s easy to share our data publicly,” Dr. Odumah said.

The University of Cape Coast’s network covers high-exposure settings across Ghana and publishes live to IQAir’s air quality platform. Stations include:

\nGold-mining communities — valley towns near active mining operations, where cooler, still air can trap pollution overnight.
\nMechanic workshops — open-air spray painting, welding, and grinding that impact daytime pollution spikes.
\nCampus & transport hubs — taxi stands and arterial roads with predictable rush-hour peaks.
\nNeighborhood milling centers — locally built grain and cassava mills that vent outdoors.

Each site acts as both a data point and a conversation starter—not only coming together to paint a fuller picture of the air quality across Ghana but helping communities see, in the data, the pollution they experience—so they can act on it.

Turning data into decisions

Real-time, new-found visibility into the air quality is changing routines. The team analyzes pollution trends across the station locations, using the AirVisual Platform, to recommend low-cost, high-impact habits—from establishing simple personal protective equipment (PPE) norms and guidelines to regular road wetting near mine haul routes.

“The platform includes particle pollution, temperature, pressure, humidity, and downloading the data is straightforward,” says Dr. Odumah, noting too that the platform makes trend analysis easier, enabling the team to provide practical guidance.

“When the air is polluted, before you can even say where it came from, it has already traveled to other people.”—Dr. Christiana Odumah, University of Cape Coast

Education and empowerment

The air quality monitors double as teaching tools. In lectures and informal workshops, Dr. Odumah’s team walks through what PM2.5 is, why some places experience worse elevated levels at certain times, and how small choices—mask use, ventilation, timing—compound into real protection and health benefits. Students help maintain stations and interpret patterns, building local capacity for work that will last beyond this specific project.

Looking ahead

The path forward combines academic rigor and reach. Dr. Odumah explained that two publications are fully drafted and a third is almost complete. “We’re hoping to submit three papers by year-end,” she said.

Next, the team plans to broaden the network and provide actionable playbooks for millers, mechanics, schools, and local authorities. Trials with secondary-pollutant sensors are planned to complement the insights already gathered. And in Tarkwa, a station will be kept in place to serve the community long-term. Dr. Odumah said: “They need constant monitoring, even if it means I can’t redeploy that unit for research.”

Conclusion

Air pollution is often invisible—but its effects are not. By putting monitors where people live and work, Dr. Christiana Odumah’s team is helping communities turn numbers into know-how—and know-how into healthier habits.

The model is simple and scalable: measure what matters, share it widely, and act together to bring clean air to the community. As Dr. Odumah said, “If people realize their health is at risk, they’ll find ways to cut emissions. That’s why we need this monitoring—so the community can act.”

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. By coordinating 15 monitoring stations under one national initiative, WWF-Pakistan now operates the country’s largest organized air quality monitoring network, making real-time data accessible to both citizens and policymakers. Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change. Using Air Quality Data to Combat Pollution in Pakistan With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan. \"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.” Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives. With 18,800 followers across its national network, WWF-Pakistan is sharing that data every day with citizens who urgently need real-time air quality information to help protect themselves from pollution. Pakistan's Long-Term Pollution Solutions WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data. \"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution.

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. By coordinating 15 monitoring stations under one national initiative, WWF-Pakistan now operates the country’s largest organized air quality monitoring network, making real-time data accessible to both citizens and policymakers.

Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change.

Using Air Quality Data to Combat Pollution in Pakistan

With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan.

\"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.”

Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives.

With 18,800 followers across its national network, WWF-Pakistan is sharing that data every day with citizens who urgently need real-time air quality information to help protect themselves from pollution.

Pakistan's Long-Term Pollution Solutions

WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data.

\"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution.

The air quality data being gathered is more than just numbers—it’s a lifeline for communities struggling with the dangers of polluted air. “Our initiative is laying the foundation for a National Clean Air Research Centre,\" Huzaifa said. \"This will be a hub for research and data-driven policies, enabling us to tackle pollution with innovative strategies.\"

How one Bangkok school uses IQAir air quality monitoring technology and student flag systems to safeguard learning.

","A Bangkok school tackling air pollution with technology At Panyarat High School (PHS) in Bangkok, students don’t just learn science—they live it. Widely recognized as one of Thailand’s leading schools for math, science, and technology, PHS has woven air quality education into the fabric of student life. Bangkok is a city where air pollution is a persistent health concern; their innovative use of an IQAir AirVisual Monitor shows that protecting students’ health is just as important as their academic performance. An educational environment built around clean air awareness Rooted in the legacy of the Rattanapian family—renowned Thai educators and former Ministry of Education leaders—PHS was founded to develop capable, compassionate citizens ready to lead in the 21st century. The school’s curriculum blends Thai cultural values with global readiness, emphasizing critical thinking, STEM skills, and environmental responsibility. Orrawee Rattanapian, School Manager at PHS, oversees operations and many of the school’s programs. “We want our students to graduate not just with knowledge, but with the curiosity and responsibility to improve their world—including the air they breathe,” Orrawee says. “We want our students to graduate not just with knowledge, but curiosity and responsibility to improve their world—including the air they breathe.”—Orrawee Rattanapian, School Manager, Panyarat High School How air quality data drives school safety decisions PHS utilizes the AirVisual monitor to collect air quality data—this data in turn drives daily decision-making. Each day, students and staff can check the current AQI (Air Quality Index) on the device’s digital readout, while a large, color-coded flag in the center of campus visually signals the day’s air quality level. These colors are backed by a detailed response policy that changes based on PM2.5 levels: Moderate: Monitor students with health conditions. Unhealthy: Cancel outdoor P.E. classes, close windows and doors. Hazardous: All outdoor activities stopped, masks advised; potential school closure.

A Bangkok school tackling air pollution with technology

At Panyarat High School (PHS) in Bangkok, students don’t just learn science—they live it. Widely recognized as one of Thailand’s leading schools for math, science, and technology, PHS has woven air quality education into the fabric of student life.

Bangkok is a city where air pollution is a persistent health concern; their innovative use of an IQAir AirVisual Monitor shows that protecting students’ health is just as important as their academic performance.

An educational environment built around clean air awareness

Rooted in the legacy of the Rattanapian family—renowned Thai educators and former Ministry of Education leaders—PHS was founded to develop capable, compassionate citizens ready to lead in the 21st century. The school’s curriculum blends Thai cultural values with global readiness, emphasizing critical thinking, STEM skills, and environmental responsibility.

Orrawee Rattanapian, School Manager at PHS, oversees operations and many of the school’s programs. “We want our students to graduate not just with knowledge, but with the curiosity and responsibility to improve their world—including the air they breathe,” Orrawee says.

“We want our students to graduate not just with knowledge, but curiosity and responsibility to improve their world—including the air they breathe.”—Orrawee Rattanapian, School Manager, Panyarat High School

How air quality data drives school safety decisions

PHS utilizes the AirVisual monitor to collect air quality data—this data in turn drives daily decision-making. Each day, students and staff can check the current AQI (Air Quality Index) on the device’s digital readout, while a large, color-coded flag in the center of campus visually signals the day’s air quality level. These colors are backed by a detailed response policy that changes based on PM2.5 levels:

\n
Moderate: Monitor students with health conditions.
\n
\n
Unhealthy: Cancel outdoor P.E. classes, close windows and doors.
\n
\n
Hazardous: All outdoor activities stopped, masks advised; potential school closure.
\n

These clear, data-driven responses make invisible air pollution risks tangible and understandable for students. “The flag system is simple, visible, and creates a shared sense of responsibility,” Orrawee explains. “It turns air quality awareness into something every student can act on, every single day.”

Schoolwide Impact—and Global Reach

PHS students are not just learning about air quality; they’re part of the solution for cleaner, safer air. Classroom discussions, science projects, and even cross-curricular initiatives often incorporate the real-time AQI data gathered by their AirVisual monitor.

Publishing their data on the IQAir AirVisual platform has been simple and intuitive, allowing the school to reach a wider community with minimal technical barriers.

“The platform makes it easy for us to share our air quality data with the public,” said Orrawee. “We can focus on education and student safety, knowing the data is reaching people who need it.”

Abbie Brockman, an educator and Valley Watch board member, has assumed much of the responsibility for the group’s air quality monitoring program.

While the OVSA stated that coal power plant pollution is the most significant source of local air pollution, Blair and Brockman noted several additional sources of regional air pollution. These can include pollutants from mines, VOC off-gassing from furniture production, metal smelters, raw plastics manufacturing and extrusion, turkey farm manure, and controlled burns and wildfire smoke from as far away as the West Coast.

However, Blair expressed distrust in the state government’s commitment to environmental pollution. “IDEM has a bad culture of thinking of itself as an economic development agency instead of environmental protection.” Blair asserted. “They don’t want to accept the data from the monitors.” Valley Watch has observed that government air quality monitors seem to “fail” on poor air quality days – exactly when access to air quality data can help inform the public. When many poor readings aren’t factored into calculating AQI averages, the published data can be skewed and makes an area’s air quality look better than it is. By contrast, low-cost air quality monitoring stations owned by individuals and activists maintain access throughout the year and provide more complete, validated data accessible by anyone via an app. Coal-to-liquid (CTL) controversy In one significant development for community health, a proposed coal-to-diesel plant in Dale lost its construction and operations permit in 2023 (6). “The refinery is no longer an issue, thanks to John, Valley Watch, Southwestern Indiana Citizens for Quality of Life, and Earth justice,” said Mary Hess, the President of SWICQL. Coal liquefaction is marketed as “clean coal” or “clean diesel” when liquefaction creates diesel. But the process isn’t as clean as advertised. There have been at least ten proposed projects to build a coal-to-liquid (CTL) plant in the area. Coal liquefaction, the process of converting coal into a liquid hydrocarbon used for fuel, is marketed as “clean coal” or “clean diesel” when liquefaction creates diesel. But the process isn’t as clean as advertised. The coal-to-diesel conversion process releases carbon into the atmosphere, a greenhouse gas. The liquefaction process is energy intensive and furthers dependency on coal mining (7,8). There are currently no coal-to-diesel plants in the United States. Despite the fact no such project has gone ahead elsewhere, the community is conflicted over the project. A region divided Valley Watch has succeeded in opposing all previously proposed area “synfuel” facilities which would convert coal to liquids, gases, and other burnable solids. That doesn’t mean new proposals will never be submitted again, though. A billboard opposing a proposed coal to diesel refinery in Dale, Indiana. Source: BlairPhotoEVV. Billboard designed by Matt Brockman. Valley Watch and SWICQL believe that providing validated, calibrated air quality data to the Ohio Valley will help better inform views and combat air pollution. There are misconceptions in the community over other sources of air pollution as well – especially given the widespread myth that country air is always cleaner than city air. Air quality in rural Dubois County can be poor in part due to the practice of spreading manure and animal by-products in fields. “Some days, it’s so foul you can barely breathe,” Brockman noted. When poor air quality from wildfires, preventative burns, VOC releases from numerous furniture factories, and coal burning converge in the valley, there can be days when the resulting poor air quality harms residents’ respiratory health – and that too can impact quality of life. As Hess recalled, a real estate agent looking at properties in the valley found that out first-hand as he drove and approached the Dale exit, his eyes began watering. “The closer he got while driving down 231, the worse it got,” she attested. While Dale and the greater community may be divided on the issues, Valley Watch and SWICQL believe that providing validated, calibrated air quality data to the community will help better inform views and combat air pollution. Conclusion Southern Indiana continues to have an air quality problem. But at least light has been shed on the problem thanks to the dedicated efforts of activist groups like Valley Watch and SWICQL. Air quality monitoring creates data that can inform decision-makers and change lives. When people are empowered through data-driven information, this is how communities can take back their health and tackle air pollution at its source.","

Valley Watch has observed that government air quality monitors seem to “fail” on poor air quality days – exactly when access to air quality data can help inform the public. When many poor readings aren’t factored into calculating AQI averages, the published data can be skewed and makes an area’s air quality look better than it is. By contrast, low-cost air quality monitoring stations owned by individuals and activists maintain access throughout the year and provide more complete, validated data accessible by anyone via an app.

Coal-to-liquid (CTL) controversy

In one significant development for community health, a proposed coal-to-diesel plant in Dale lost its construction and operations permit in 2023 (6).

“The refinery is no longer an issue, thanks to John, Valley Watch, Southwestern Indiana Citizens for Quality of Life, and Earth justice,” said Mary Hess, the President of SWICQL.

Coal liquefaction is marketed as “clean coal” or “clean diesel” when liquefaction creates diesel. But the process isn’t as clean as advertised.

There have been at least ten proposed projects to build a coal-to-liquid (CTL) plant in the area. Coal liquefaction, the process of converting coal into a liquid hydrocarbon used for fuel, is marketed as “clean coal” or “clean diesel” when liquefaction creates diesel. But the process isn’t as clean as advertised.

The coal-to-diesel conversion process releases carbon into the atmosphere, a greenhouse gas. The liquefaction process is energy intensive and furthers dependency on coal mining (7,8).

There are currently no coal-to-diesel plants in the United States. Despite the fact no such project has gone ahead elsewhere, the community is conflicted over the project.

A region divided

Valley Watch has succeeded in opposing all previously proposed area “synfuel” facilities which would convert coal to liquids, gases, and other burnable solids. That doesn’t mean new proposals will never be submitted again, though.

Valley Watch and SWICQL believe that providing validated, calibrated air quality data to the Ohio Valley will help better inform views and combat air pollution.

There are misconceptions in the community over other sources of air pollution as well – especially given the widespread myth that country air is always cleaner than city air. Air quality in rural Dubois County can be poor in part due to the practice of spreading manure and animal by-products in fields.

“Some days, it’s so foul you can barely breathe,” Brockman noted.

When poor air quality from wildfires, preventative burns, VOC releases from numerous furniture factories, and coal burning converge in the valley, there can be days when the resulting poor air quality harms residents’ respiratory health – and that too can impact quality of life. As Hess recalled, a real estate agent looking at properties in the valley found that out first-hand as he drove and approached the Dale exit, his eyes began watering.

“The closer he got while driving down 231, the worse it got,” she attested.

While Dale and the greater community may be divided on the issues, Valley Watch and SWICQL believe that providing validated, calibrated air quality data to the community will help better inform views and combat air pollution.

Conclusion

Southern Indiana continues to have an air quality problem. But at least light has been shed on the problem thanks to the dedicated efforts of activist groups like Valley Watch and SWICQL.

Air quality monitoring creates data that can inform decision-makers and change lives. When people are empowered through data-driven information, this is how communities can take back their health and tackle air pollution at its source.

Learn how air purifiers reduce smoke particles, where they help most, and how to protect indoor air during wildfire events.

","Yes—air purifiers can help reduce wildfire smoke indoors, but only when they are used correctly and paired with other protective measures. Wildfire smoke introduces a harmful mix of fine particles and gases that interact with indoor spaces differently than typical, short-lived household air pollutants. Understanding how it enters homes—and how it affects health—is essential to using air filtration effectively. Why wildfire smoke presents unique indoor air challenges When people think about wildfires, flames and evacuations often come to mind. In reality, smoke inhalation is the greatest health risk from wildfires, even for people living far from the fire itself. Wildfire smoke can travel long distances, infiltrate buildings, and linger indoors long after outdoor air appears to improve. Importantly, staying indoors alone is not enough to protect against wildfire smoke. Wildfire smoke can travel far Wildfire smoke does not stay close to where a fire burns. Research has shown that smoke plumes can rise to high altitudes and travel hundreds or even thousands of miles, affecting communities far removed from the fire itself. In recent wildfire seasons, smoke from large fires has been detected across continents, contributing to degraded air quality and elevated ozone levels in distant urban areas. While wildfire smoke is often associated with coughing or breathing difficulty, studies increasingly show that its health impacts go beyond the lungs. Fine particulate matter (PM2.5)— particles 2.5 microns or smaller—from wildfire smoke has been linked to increased risk of cardiovascular events, including heart attacks and cardiac arrest, particularly among older adults and people with pre-existing heart disease. These findings help explain why wildfire smoke can be dangerous even when flames are nowhere nearby, and why protecting indoor air quality during smoke events is critical for a wide range of health risks—not just respiratory symptoms. Urban wildfire smoke Wildfires are no longer confined to remote forests. Increasingly, fires are burning in urban and suburban areas, where homes, vehicles, plastics, and infrastructure become part of the fuel. When these materials burn, wildfire smoke contains far more than soot from vegetation—it carries a complex mix of toxic chemicals and particles, many among them the 10 most harmful pollutants most people breathe every day. Research has shown that PM2.5 from urban wildfires can be significantly more harmful to human health than fine particles from other pollution sources. In addition to fine and ultrafine particles, urban wildfire smoke may contain elevated levels of volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals released from burned buildings, vehicles, and consumer materials. This added chemical burden helps explain why urban wildfire smoke can pose greater risks to both respiratory and cardiovascular health, and why indoor air protection becomes especially important during fires near populated areas. Who is most at risk from wildfire smoke? While anyone can be affected by wildfire smoke, certain groups are more vulnerable: Young children Pregnant individuals Older adults People with asthma, COPD, or other respiratory conditions Individuals with cardiovascular disease Symptoms may not appear immediately—health effects can be delayed by 24–48 hours, even after exposure has ended. What’s in wildfire smoke? Wildfire smoke isn’t a single pollutant—it’s a complex mixture of particles and gases that behave differently once inhaled. The most harmful include: Fine particulate matter (PM2.5)—particles 2.5 microns or smaller Ultrafine particles (PM1 and smaller)—capable of entering the bloodstream Carbon monoxide (CO) and other combustion gases Nitrogen oxides and ozone-forming compounds VOCs such as formaldehyde and acrolein Among these, fine and ultrafine particles pose the greatest immediate health risk because they penetrate deep into the lungs. Ultrafine particles are particularly concerning because, once inhaled, they can pass from the lungs into the bloodstream and reach organs throughout the body. How wildfire smoke gets indoors Many people assume that closing doors and windows keeps smoke outside. Unlike many household pollutants that originate indoors and dissipate quickly, wildfire smoke can be continuously driven indoors by outdoor conditions. Smoke enters buildings through: Cracks and gaps around doors and windows Building materials that are not fully airtight HVAC systems drawing in outside air Frequent opening of doors during daily activity Once inside, smoke particles can become trapped, settle on surfaces, and be re-suspended into the air with normal movement, allowing smoke pollution to persist indoors even after the original source has passed. All of these factors point to the same reality: during wildfire smoke events, reducing indoor exposure becomes the most practical way to protect health. How air purifiers help reduce smoke exposure indoors Air purifiers help primarily by removing airborne particulate matter, which is the most dangerous component of wildfire smoke. High-performance air purifiers are effective at capturing: PM2.5 particles Ultrafine particles, including those smaller than 0.1 microns By continuously filtering indoor air, these systems can significantly reduce smoke particle concentrations in enclosed spaces—especially when windows and doors remain closed. However, it’s important to recognize that air purifiers do not stop smoke from entering a home. They reduce exposure after infiltration has occurred. Why homes can still feel smoky—even with filtration Even with an air purifier running, people may still notice smoke indoors.

Short-term improvements depend on weather. Wind, rain and stronger mixing can lower concentrations within days, but calm, cool conditions and winter temperature inversions will trap pollutants and prolong smog episodes through the October–February smog season. Lasting improvement requires policy action and seasonal controls. Without those, severe episodes are likely to recur each winter (1). What is causing poor air quality in Pakistan? The root causes of air pollution in Pakistan include industrial emissions, vehicular exhausts, agricultural practices like overuse of fertilizers and crop residue burning, biomass and waste burning, domestic fires, and urbanization (2).

Is the air quality good in Pakistan?

As of February 12, 2026, air quality in Pakistan remains poor, with major cities experiencing \"unhealthy\" to \"very unhealthy\" levels and high PM2.5 concentrations, posing serious health risks to residents, especially children and the elderly.

By 10:00 AM (Pakistan Standard Time), many 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, Pakistan’s average PM2.5 concentration in 2024 was 73.7 µg/m³, equivalent to an AQI of 160, classified as “unhealthy.” This level is nearly 15 times higher than the WHO annual guideline of 5 µg/m³, placing Pakistan third globally in the 2024 World Air Quality Report.

When will the air quality improve in Pakistan?

Short-term improvements depend on weather. Wind, rain and stronger mixing can lower concentrations within days, but calm, cool conditions and winter temperature inversions will trap pollutants and prolong smog episodes through the October–February smog season. Lasting improvement requires policy action and seasonal controls. Without those, severe episodes are likely to recur each winter (1).

What is causing poor air quality in Pakistan?

The root causes of air pollution in Pakistan include industrial emissions, vehicular exhausts, agricultural practices like overuse of fertilizers and crop residue burning, biomass and waste burning, domestic fires, and urbanization (2).

In the winter season, pollution intensifies due to widespread stubble burning after rice harvests, which releases PM2.5, NOx, and ozone precursors, combined with temperature inversions, low winds, cold temperatures, and reduced rainfall that trap pollutants, forming dense smog in cities.

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.

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?

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.

$\"Air$

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:

\nHyperHEPA media for particle filtration
\nNo system leakage due to sealed filter and purifier housing
\nActivated 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):

\nIonizer 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.
\nIonizer 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. \n

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):

\nOzone can take years to fully clear even a small room of gases.
\nOzone 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.
\nIndoor 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):

\nBacteria 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.
\nSome bacteria can come back to life and become infectious again even after being disinfected by UV light.
\nUV 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.
\nUV 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.

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.2The 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: Stratospheric 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. Tropospheric 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 Fever3,4 Further research suggests that ozone is also responsible for long-term health problems, such as asthma, heart disease, and lung disease.

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.6Take the claims with a grain of...well, saltSo 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.You can take many precautions to monitorand keep your indoor air clean, but buying a salt lamp isn’t one of them. Try these proven methods instead: Be aware of your indoor air quality. The AirVisual Series consists of portable air quality monitors that use cutting-edge laser technology to give you real-time measurements of key pollutants, including particulate matter. AirVisual Series also provides 72-hour historical and forecast data so that you can know exactly when and why your indoor air quality changes. Control sources of poor indoor air quality. If you’re thinking about buying a salt lamp to purify your air, chances are that you do have air quality issues that you may be able to do something about. The first step to improving your indoor indoor air quality is source control.This means eliminating individual sources of pollution or reducing their emissions. Regularly clean your HVAC system ducts. Install a whole-house air purifier into your HVAC system to reduce indoor pollutants by up to 95%. Replace water-damaged areas of your home to prevent mold and dust mites. Keep paints, solvents, and other chemicals in well-ventilated areas. Ventilate your home. Let in fresh air regularly to lower the concentrations of indoor air pollutants. This is especially important if you live in an airtight, energy-efficient home in which indoor pollutants have nowhere to go and thus build up to dangerous levels. Open doors and windows when outdoor air quality is good. Use a range hood for your stove to capture gases and volatile organic compounds (VOCs) from cooking. Use an air purifier with HyperHEPA technology. The IQAir HealthPro Plusis the best air purifier for even the smallest pollutant particles, removing up to 99.5% of particulates down to 0.003 microns, like viruses and ultrafine particles from vehicle exhaust.

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.

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.

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

There are two main types of ozone:

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.

You can take many precautions to monitorand keep your indoor air clean, but buying a salt lamp isn’t one of them. Try these proven methods instead:

\nBe aware of your indoor air quality. The AirVisual Series consists of portable air quality monitors that use cutting-edge laser technology to give you real-time measurements of key pollutants, including particulate matter. AirVisual Series also provides 72-hour historical and forecast data so that you can know exactly when and why your indoor air quality changes.
\nControl sources of poor indoor air quality. If you’re thinking about buying a salt lamp to purify your air, chances are that you do have air quality issues that you may be able to do something about. The first step to improving your indoor indoor air quality is source control.This means eliminating individual sources of pollution or reducing their emissions.\n\n\t
- Regularly clean your HVAC system ducts. Install a whole-house air purifier into your HVAC system to reduce indoor pollutants by up to 95%.
- Replace water-damaged areas of your home to prevent mold and dust mites.
- Keep paints, solvents, and other chemicals in well-ventilated areas.
\n\n\t
\nVentilate your home. Let in fresh air regularly to lower the concentrations of indoor air pollutants. This is especially important if you live in an airtight, energy-efficient home in which indoor pollutants have nowhere to go and thus build up to dangerous levels.\n\n\t
- Open doors and windows when outdoor air quality is good.
- Use a range hood for your stove to capture gases and volatile organic compounds (VOCs) from cooking.
\n\n\t
\nUse an air purifier with HyperHEPA technology. The IQAir HealthPro Plusis the best air purifier for even the smallest pollutant particles, removing up to 99.5% of particulates down to 0.003 microns, like viruses and ultrafine particles from vehicle exhaust. The Atempersonal air purifier can also provide pure, pollutant-free air directly into your personal breathing zone.

Sure, a salt lamp can be a nice accessory and bring some calm into your home. But there’s plenty you can do to actually keep your indoor air clean and bring yourself some peace of mind knowing that your home is a clean air sanctuary.

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. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). 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.

According to Dr. Touray, Permian Health is conducting an inventory assessment to determine the key sources of pollution, such as waste burning, reliance on charcoal and firewood for cooking, and transport-related emissions. \"Looking ahead, we aim to strengthen our collaboration with the NEA and the Ministry of Health, to expand and maintain our sensor network.\"

\"We plan to enhance public awareness campaigns, especially during high-risk periods, to better inform the community about air quality concerns. We would also like to engage more with local TV stations for them to display air quality and weather information from our network.

Conclusion

Dr. Sunkaru Touray's work with Permian Health exemplifies innovative activism. The project not only addresses air quality data gaps but also empowers communities to tackle air pollution—an issue that transcends borders.

Dr. Touray's mission goes beyond air quality monitoring; it's about transforming the quality of public health around the world.

A kitten rescue in Ontario needed a powerful clean air solution fast – and found it. Learn more about the essential role of clean air in shelters.

","Nestled in a small town near Cornwall, Canada, Tiny but Mighty Kitten Rescue serves as a lifeline for abandoned and vulnerable kittens (1). For nearly eight years, rescue founder Mellissa has worked tirelessly to save and nurture the most fragile feline lives in the region. Yet despite Mellissa’s dedication to maintaining a clean environment for those in her care, animal rescues must always contend with a formidable health challenge. Poor air quality impacts both kittens and the humans who care for them. Thanks to advanced air purification technology, the rescue now breathes easier—literally and figuratively. Mission built on compassion Mellissa’s journey to creating Tiny but Mighty began with heartbreak. As a volunteer at her local animal shelter, she learned of the euthanasia of kittens deemed too young to care for. Unwilling to accept this outcome, she founded her own kitten-focused rescue in 2017. “I had so many dreams about saving these kittens. Something told me to just do it myself—start my own rescue.” “I had so many dreams about saving these kittens. They wouldn’t let up,” Mellissa shared. “Something told me to just do it myself—start my own rescue.” Mellissa provides a safe space for kittens to grow and thrive until they find their carefully screened forever homes. Today, the rescue operates solely on donations and community support. “It’s such an incredible community. People do come through to support what I’m doing, so it’s incredible.” But running a rescue isn’t without its challenges, and one significant one she uncovered was air quality. Nova the kitten enjoying toys at the Tiny but Mighty Kitten Rescue. Good air quality: Essential in animal rescues Caring for kittens in any enclosed environment presents unique challenges. Despite her meticulous cleaning habits, Mellissa found air quality to be a problem. “The dust is crazy. The kittens will go in their litter box and sneeze.” There would still be dust, odors, and allergens in the space “even though I use 99% dust-free litter.” Mellissa explained. “It’s great compared to some I’ve tried, but the dust is crazy. The kittens will go in their litter box and make little sneezes.” This poor air quality not only affected visitors but also had potential health implications for the kittens and Mellissa herself. Dust mites, microscopic creatures that feed on animal’s dead skin, can cause year-round allergic reactions in both cats and humans, including sneezing, runny and itchy noses, watery eyes, and even rashes. Components of pet dander can also act as an allergen, triggering similar reactions. Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs. Life changing air cleaning solution Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively. Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’” That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable. The HealthPro Plus XE is equipped with HyperHEPA filtration, capable of capturing particles as small as 0.003 microns—100 times smaller than most air purifiers can filter. This efficiency, proven to remove particles far smaller than bacteria or viruses, combined with gas-phase filtration to eliminate odors, made it an ideal solution for the rescue’s air quality challenges. “The kittens aren’t sneezing anymore. The air purifier has had a huge impact,” Mellissa shared. The HealthPro Plus XE at work next to Leia the cat. Not only did she see a dramatic improvement in the air quality for the kittens, but visitors also noticed the difference. The previously lingering food and litter odors were gone. “I definitely don’t smell that anymore,” Mellissa said. “I’m really impressed.” “The kittens aren’t sneezing anymore. The air purifier has had a huge impact.” When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night. Looking ahead For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes. The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens. Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.” Conclusion Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal. For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable. By addressing the often-overlooked issue of air quality, she has set a powerful example for other rescues, shelters, and even individual pet owners facing similar challenges.","
