See why Dr. Stanely, a tireless advocate for systemic healthcare, invested in high performance air filtration for his world-renowned dental clinic.

","Dr. Miguel Stanley is the founder and clinical director of the White Clinic in Lisbon, Portugal (1). His patients travel to him from around the world; among his clients are famous athletes and celebrities. “I'm an old school dentist doing advanced integrative dentistry,” he said. “One of the fastest growing trends in dentistry is connecting the mouth to the rest of the body.” – Dr. Miguel Stanley When he’s not doing clinical work, Dr. Stanley advocates and educates both colleagues and the public on the crucial role oral health plays in our overall health, and has lectured in over 50 countries (2). As the co-founder the Slow Dentistry Global Network, Dr. Stanley is dedicated to bettering the safety and experience of patients around the globe. And as an adjunct professor at the University of Pennsylvania School of Dentistry, he’s noted hundreds of keynote lectures given over the course of 25 years. Around 2018, Dr. Stanley decided to transition his private practice towards integrative healthcare. “One of the fastest growing trends in dentistry is connecting the mouth to the rest of the body.” In line with this trend of comprehensive health care, Dr. Stanley incorporated many advanced technologies including IQAir’s advanced air filtration systems to enhance the overall wellness environment within his clinic. State-of-the-Art equipment for enhanced patient care The White Clinic boasts a wide array of equipment, ranging from hyperbaric oxygen therapy (HBOT) to Low-Level Laser Therapy (LLLT), and cryotherapy and hydrogen inhalation for wound-healing and pain relief. Yet there was one technology Dr. Stanley wanted to invest in to improve not only the well-being of his patients but also himself and his staff at the clinic. Dr. Stanley's commitment to advanced dental care extends beyond cosmetic enhancements; he sees oral health as a window to overall wellness. This perspective is why he eventually incorporated IQAir’s air filtration technologies—because clean air in the clinic does more than protect against immediate contaminants; it’s integral to holistic health outcomes. IQAir: An essential addition As the global COVID-19 pandemic sparked shutdowns and quarantines, Dr. Stanley’s clinic was the first dental clinic in Portugal to close its doors for safety. He understood that he’d need a practical solution for keeping his patients and staff safe. IQAir’s reputation for excellence stood out to him. “I trust Swiss tech a lot. I've always invested in quality, and I hold the belief that if it's something that is important to you, you have to buy the best.” Dr. Stanley purchased four IQAir CleanZone systems for his clinic. Armed with IQAir’s patented HyperHEPA filtration technology (far superior to standard HEPA filters and proven to trap more than 99.5% of particles down to 0.003 microns—a level of filtration crucial in dental clinics), the White Clinic would be well-protected from bacteria and viruses like SARS-CoV-2, the virus that causes COVID-19. “IQAir filtration became an essential part of our medical armamentarium.” “IQAir filtration became an essential part of our medical armamentarium throughout dental procedures and improved the air quality for everyone in the room. We use it for our laser surgery to filler aerosols as well as mercury amalgam removal under the SMART protocol,” Dr. Stanley said. Seeing the clean air difference In his medical advocacy, Dr. Stanley notes that it’s essential for dentists to always place safety first in their practices. This is foundational for Slow Dentistry. Doctors, surgeons, and dentists all generate aerosols in their practice. From chemical disinfectants to higher-than-average levels of inorganic mercury (Hg), there is demonstrable increased risk of poor health impacts from aerosolized pollutants. Extraoral suction and negative pressure equipment, which Dr. Stanley invested in during dental treatments, is a central component to safe, effective dentistry. But beyond his immediate practice needs, he wanted to elevate the air quality in his practice to the highest possible standard. Dr. Stanley runs his IQAir systems at the highest possible setting. And in his practice, he can actually see the systems working to keep him and his team safe. Aerosols that could impact his safety are visible. “I use and Er-Yag laser for surgery and because I also use Zeiss microscope magnification with LED light, I can see this cloud of aerosols magnified. I can really see it's being sucked into the IQAir tube. I can actually see it, so I'm not feeling it. That is worth gold to me.” Safe, effective air cleaning technology, Dr. Stanley feels, is essential for a wide variety of medical settings. “Adopting IQAir’s filtration technology has been a game-changer, ensuring that our practice not only meets but exceeds health and safety standards. This technology is pivotal and should become a standard in dental practices worldwide for its undeniable benefits in protecting both patients and staff.” “This technology is pivotal and should become a standard in dental practices worldwide for its undeniable benefits in protecting both patients and staff.” The future of dentistry Dr. Stanley’s advocacy and grounding in systemic healthcare, connecting all aspects of the body to better health outcomes and great longevity, is a fundamental aspect of his practice. \"I envision a future where everyone understands the true foundations of longevity—embracing simple, vital practices like healthy eating, sound sleep, and avoiding harmful habits.” Dr Stanley has also recently developed MissingLink, an AI platform that can scan dental X-rays and looking for hidden pathologies that patients can also use. As Dr. Stanley said, “Its a simple tool that connects doctors to dentists.” The takeaway By investing in IQAir’s advanced air purification systems, Dr. Stanley extends his holistic health philosophy into every aspect of his practice, thus safeguarding both patients and staff against airborne pollutants. He would love to see more patients take an active role in their own healthcare, and to better understand how systemic healthcare care improve longevity and healthful living. Part of that solution requires access to clean, healthy air. He encourages other dentists to investigate high performance air filtration for their practices as well. And he was satisfied with his own investment in IQAir filtration. “They're very robust, very trustworthy, and the price and quality are amazing.”","

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.

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.\" “Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan.” In October 2024, WWF-Pakistan warned that Lahore’s air quality posed a terrible threat to public health, recommending a number of changes to government policy including helping farmers manage crop waste, expanding mass transit, and improving zoning laws to reduce industrial pollution away from residents. It also noted that low-cost air quality monitoring systems could be used to uncover air pollution hotspots along traffic routes. Armed with that information, governments could restrict heavy transport vehicles or develop alternate routes to avoid congestion (1). Beyond their air quality monitoring project, the WWF-Pakistan team oversees more than 60 active environmental protection initiatives in FY 2025 across the country, ranging from clean water access and forest preservation to sustainable infrastructure development. These efforts, working in tandem with the air quality monitoring network, are all part of WWF's broader mission to protect the planet's natural environment and create a future where both people and nature can thrive in harmony. The Takeaway WWF-Pakistan's initiative is a testament to the transformative power of air quality data, technology, and collective will in addressing one of today’s most pressing challenges. And by increasing the footprint of air quality monitors across the country, innovative solutions to persistent pollution problems can be put into play. As this vital work advances, it invites everyone to contribute to the cause—because in the fight for clean air, every voice and every action matters. “This initiative,” Nazifa said, “lays the foundation for what we envision as Pakistan’s future air quality innovation hub. It will serve as a hub for developing strategies and methods to tackle air pollution, aligning efforts across governmental and non-governmental sectors, both locally and internationally, in the fight against climate change.”","

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

","“Every day, I witness the severe impact of poor air quality on my community,” Tedy Mwendwa explained. “Using my expertise in electrical engineering, I felt compelled to create change.” In the heart of Africa, amidst bustling cities and vibrant rural landscapes, Mwendwa is pioneering a movement for cleaner air in Kenya. With a professional foundation in electrical engineering and a passion for environmental stewardship, Mwendwa's deployment of a low-cost air quality sensor in Kenya’s capital city, Nairobi, marks a pivotal step in revealing and addressing pollution and bridging critical gaps in Africa’s air quality data. Nairobi's leap towards cleaner air In late 2021, Mwendwa established an air quality station. Set up along one of Nairobi’s busy thoroughfares, the station gathers data on pollutants from sources like vehicular exhaust and biomass burning. \"It's about leveraging technology to unveil the hidden dangers of pollution.” “It's about leveraging technology to unveil the hidden dangers of pollution,” Mwendwa said. “Empowering our community with this data is crucial for driving action and advocating for sustainable solutions. Without data, we remain in the dark.” Local expertise, global resources drive innovation Building on the foundation of community-driven air monitoring, the project has taken a step forward. It now hosts East Africa’s first Monster Aerosol System (a platform that houses advanced aerosol analyzers), featuring a Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM). This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—uncovering the chemical fingerprints of pollution with unprecedented precision. Paired with a black carbon monitor, the system offers a comprehensive view of airborne composition and sources. These reference-grade instruments build on the project’s original IQAir AirVisual Outdoor monitor—pairing community-level, real-time data with laboratory-grade chemical insight. The TOF-ACSM will help identify pollution sources—from mineral dust kicked up by unpaved roads and construction to organic aerosols tied to biomass burning and traffic emissions. It will also track seasonal and daily shifts in air quality, influenced by weather patterns and human activity. The initiative is expanding further with the deployment of GRIMM EDM 180 reference monitors across Nairobi, replacing older equipment to deliver faster, more accurate readings with minimal maintenance. In collaboration with the Kenya National Highways Authority (KENHA), these monitors will be placed along major highways and construction zones, ensuring data reflects the realities of urban life. These advancements are part of the NBO-CHEM Project (Nairobi Aerosol Chemistry and Monitoring Initiative), an effort funded by the U.S. National Science Foundation (NSF) and led by Prof. Daniel M. Westervelt, Dr. Godwin Opinde, and Tedy Mwendwa. By combining local expertise with state-of-the-art scientific resources, the project aims to transform how we understand air pollution in East Africa. The challenge of air quality monitoring in Africa The new additions to the project are heartening developments towards advancing air quality understanding in East Africa. Yet, despite the increasing efforts to monitor air quality globally, Africa remains one of the most underrepresented continents in terms of air quality data. According to the 2024 World Air Quality Report, there is only one monitoring station for every 3.7 million people. While coverage has expanded to include more African countries in recent years, there are still vast areas without sufficient data. For example, countries like Niger and Sudan remain without publicly available monitoring data.Air pollution is a major health threat, causing an estimated seven million premature deaths worldwide each year. Without accurate data, it is challenging to address the sources and impacts of air pollution effectively. Grassroots efforts like Mwendwa's are crucial in filling these data gaps, providing models for further projects and inspiring broader initiatives.

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

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

Nairobi's leap towards cleaner air

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

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

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

Local expertise, global resources drive innovation

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

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

The initiative is expanding further with the deployment of GRIMM EDM 180 reference monitors across Nairobi, replacing older equipment to deliver faster, more accurate readings with minimal maintenance. In collaboration with the Kenya National Highways Authority (KENHA), these monitors will be placed along major highways and construction zones, ensuring data reflects the realities of urban life.

These advancements are part of the NBO-CHEM Project (Nairobi Aerosol Chemistry and Monitoring Initiative), an effort funded by the U.S. National Science Foundation (NSF) and led by Prof. Daniel M. Westervelt, Dr. Godwin Opinde, and Tedy Mwendwa.

By combining local expertise with state-of-the-art scientific resources, the project aims to transform how we understand air pollution in East Africa.

The challenge of air quality monitoring in Africa

The new additions to the project are heartening developments towards advancing air quality understanding in East Africa. Yet, despite the increasing efforts to monitor air quality globally, Africa remains one of the most underrepresented continents in terms of air quality data. According to the 2024 World Air Quality Report, there is only one monitoring station for every 3.7 million people.

While coverage has expanded to include more African countries in recent years, there are still vast areas without sufficient data. For example, countries like Niger and Sudan remain without publicly available monitoring data.

Air pollution is a major health threat, causing an estimated seven million premature deaths worldwide each year. Without accurate data, it is challenging to address the sources and impacts of air pollution effectively. Grassroots efforts like Mwendwa's are crucial in filling these data gaps, providing models for further projects and inspiring broader initiatives.

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. Official Air Purifiers Guide: Learn why some air purifiers work and some don't → 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.

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

\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.

How wildfire smoke behaves Many factors affect wildfire smoke behavior, such as: weather geographical terrain the stage of the fire wind Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you. Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source.

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

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
\n
\n
Use an air quality monitoring app to keep track of pollutants in your environment. The AirVisual app displays real-time hyperlocal data from over 80,000 sensors around the world. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO₂, and NO₂, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health.

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

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

The takeaway

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

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

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

Air quality map of Lahore, Pakistan, as of May 29, 2026, at 4:00 PM (local time). Source: IQAir. When will the air quality improve in Lahore? Short-term improvements depend on weather, as wind, rain, and stronger atmospheric mixing can lower PM2.5 concentrations within days. In spring, as temperatures increase, hot air rises and cooler air sinks, which can ease pollution. However, stagnant air, low winds, and high heat can still trap pollutants near the surface. Full relief is expected with the monsoon season from June through September, which washes away pollutants. Lasting improvement will require sustained policy enforcement, reductions in crop burning, and accelerated adoption of cleaner energy and transport alternatives (1). Hourly air quality forecast for Lahore, Pakistan, as of May 29, 2026, at 4:00 PM (local time). Source: IQAir. What is causing poor air quality in Lahore? Vehicle emissions account for approximately 40 to 45% of Lahore's air pollution, while industrial emissions contribute around 30%, forming the backbone of the city's chronic smog crisis alongside crop burning in surrounding agricultural areas (2). Research shows that over the past decade, crop residue burning and motor vehicle emissions have greatly contributed to the increased frequency and intensity of severe pollution episodes, now so persistent they are referred to as \"the fifth season\" across cities in the Punjab region (3). Other contributing sources include unregulated brick kilns, biomass and waste burning, domestic fires, and construction dust from rapid urbanization. According to estimates by the Centre for Research on Energy and Clean Air, poor air quality is responsible for up to 235,000 premature deaths per year across Pakistan (4).

Full relief is expected with the monsoon season from June through September, which washes away pollutants. Lasting improvement will require sustained policy enforcement, reductions in crop burning, and accelerated adoption of cleaner energy and transport alternatives (1).

What is causing poor air quality in Lahore?

Vehicle emissions account for approximately 40 to 45% of Lahore's air pollution, while industrial emissions contribute around 30%, forming the backbone of the city's chronic smog crisis alongside crop burning in surrounding agricultural areas (2).

Research shows that over the past decade, crop residue burning and motor vehicle emissions have greatly contributed to the increased frequency and intensity of severe pollution episodes, now so persistent they are referred to as \"the fifth season\" across cities in the Punjab region (3).

Other contributing sources include unregulated brick kilns, biomass and waste burning, domestic fires, and construction dust from rapid urbanization. According to estimates by the Centre for Research on Energy and Clean Air, poor air quality is responsible for up to 235,000 premature deaths per year across Pakistan (4).

First, second, and thirdhand smoke doesn’t disappear when a cigarette is extinguished. Learn how it lingers in the air, spreads across surfaces, and affects indoor environments over time.

","Smoke does not disappear when a cigarette is extinguished. Particles and gases linger in the air and settle onto surfaces, continuing to affect indoor environments long after smoking stops. What many people don’t realize is that these particles don’t just linger—they continuously move between air and surfaces, re-circulating indoors over time. What is firsthand, secondhand, and thirdhand smoke? Traditionally, tobacco smoke is consumed directly through lighting a cigarette and inhaling the substance, also known as firsthand exposure. However, involuntary or indirect modes of consumption can happen daily without a person even realizing it. From secondary inhalation to residue build-up, all the different types of tobacco smoke exposures include (1): Firsthand: Direct inhalation of tobacco smoke chemicals by an individual, commonly resulting in elevated personal health risks from heart disease to lung cancer and respiratory complications. Secondhand: Also known as passive smoking, this is the involuntary or indirect inhalation of tobacco smoke by a non-smoking person. If exposed, individuals could encounter over 7,000 various chemicals, including over 70 carcinogens. Long-term secondhand exposure increases physical and mental health risks, especially when an individual is in ill-ventilated areas or indoor spaces. Thirdhand: Tobacco smoke residue that clings and gradually accumulates on top of commonly exposed surfaces such as furniture, walls, and clothing. The tobacco residue often contains toxins and poisonous compounds that are especially harmful to infants, toddlers, and animals who may encounter and ingest these particles. Unlike airborne smoke that dissipates, thirdhand smoke can persist on surfaces for weeks or even months, continuing to release harmful compounds back into the air long after smoking stops. How tobacco smoke affects indoor air quality When cigarettes are combusted, they release smoke containing high concentrations of PM2.5 and PM10 particulate matter that can linger and migrate. PM2.5 are airborne particles the size of 2.5 microns or less and PM10 encapsulate particles the size of 10 microns or less. When these pollutants are inhaled, they can cause systemic harm to the human body. In enclosed spaces, smoking can raise fine particle concentrations to levels up to 100 times higher than typical outdoor air—turning indoor environments into some of the most polluted spaces people encounter. Smoking also directly contributes to the production of harmful gases and chemical pollutants, commonly known as volatile organic compounds (VOCs). Tobacco smoke specifically has been found to be linked to benzene, a common carcinogen that is known to cause leukemia, bone marrow damage, and anemia through long-term exposure (2). These dynamics are especially pronounced in indoor environments, where airflow is limited and pollutants are more likely to accumulate over time. Indoor smoking leads to long-term exposure Smoking indoors introduces pollutants into a contained environment where they can accumulate, settle, and recirculate over time. Unlike outdoor environments, indoor spaces often lack sufficient airflow to disperse smoke quickly, allowing particles and gases to persist well beyond the act of smoking itself. For this reason, avoiding indoor smoking completely is the most effective way to reduce exposure to both airborne and surface-bound contaminants associated with smoking. Secondhand smoke doesn’t always dissipate outdoors This persistence is not limited to indoor environments. It is often assumed that secondhand smoke quickly disperses outdoors and poses little risk. However, research suggests that this is not always the case—particularly in partially enclosed spaces such as patios, outdoor dining areas, and building entrances. In these environments, secondhand smoke can reach concentrations comparable to indoor spaces where smoking is permitted. Exposure levels can vary depending on the number of smokers, proximity, and airflow conditions, with individuals downwind often experiencing the highest concentrations. Even at a distance, smoke particles can remain detectable and irritating. In some cases, outdoor smoke can drift into adjacent indoor areas or accumulate in semi-enclosed spaces, extending exposure beyond the immediate source (3). Studies have shown that secondhand smoke can be detected and cause irritation at distances of more than 10–20 feet from the source, particularly when individuals are positioned downwind. In outdoor settings with multiple smokers or partial enclosure, exposure levels can approach those found indoors—lasting for as long as smoking activity continues and, in some cases, persisting after the source is gone (4). These findings challenge the assumption that outdoor smoking eliminates risk, highlighting how secondhand smoke can persist and spread across both indoor and outdoor environments. Thirdhand smoke can further extend this exposure. Residual particles that settle onto clothing, skin, or surfaces outdoors can be carried back into indoor environments, where they continue to release harmful compounds over time. This means that even when smoking occurs outside, its effects can still persist indoors. How smoking regulations shape indoor air quality U.S. State and federal smoking laws have been in place since the 1960s to ensure public safety and limit indirect exposure. The Federal Cigarette Labeling and Advertising Act, enacted in July 1965, was one of the first anti-smoking laws, requiring transparent health warnings and restricting false advertising of cigarette products nationwide (5). Today, many policies extend into private spaces, as business owners take it upon themselves to limit tobacco exposure to ensure public safety. Tobacco and smoking regulations are becoming increasingly popular worldwide as well. In 2024, Canada was the first country in the world to mandate transparent health warnings on each cigarette individually, with bold black text printed on every stick (6). Also in the same year, the United Kingdom introduced a Tobacco and Vapes Bill, which would ban those under the age of 15 from purchasing tobacco beginning 2027 (7). In a separate ruling, the United Kingdom has also banned the sell and purchase of disposable vapes to address issues in underage smoking (8). For shared buildings and apartment complexes, anti-smoking regulations and designated smoking areas are the key to securing a healthy space for everyone, as cigarette smoke can be transported easily through open windows and air vents or stick to commonly used surfaces (9). Limiting tobacco smoke exposure doesn’t stop at smoking rules and regulations, it also depends on a building’s air filtration system. Because tobacco smoke includes both particles and gases, reducing exposure requires more than a single approach. How filtration can help reduce tobacco smoke exposure Source control—preventing smoke from entering the environment in the first place—is the most effective way to reduce exposure. HyperHEPA filtration is designed to capture 99.5% of airborne particulate as small as 0.003 microns, helping reduce tobacco smoke particles and odors. However, tobacco smoke is not made up of particles alone—it also contains a complex mix of gases and chemical pollutants. Gas-phase filtration, such as activated carbon, is designed to adsorb volatile organic compounds (VOCs), benzene, and other harmful chemicals present in smoke. By combining particle filtration with gas-phase filtration, air purification systems can address a broader range of pollutants found in tobacco smoke. When paired with proper ventilation and HVAC systems, these approaches can help reduce overall exposure to both particulate and chemical components of tobacco smoke. Reducing exposure to secondhand smoke indoors Reducing exposure to tobacco smoke often involves a combination of building-level policies and individual actions. In homes or shared spaces where smoking occurs, reducing exposure often depends on how air moves, how surfaces are managed, and how consistently these strategies are applied: Improving filtration and ventilation in shared indoor spaces. Limiting indoor smoking and separating smoking areas where possible. Using air filtration to reduce airborne smoke particles and odors Monitoring indoor air quality to better understand exposure levels. Addressing thirdhand smoke on surfaces Thirdhand smoke also plays a role in ongoing exposure. Because smoke residues can accumulate on surfaces and in materials like carpets, upholstery, and clothing, regular cleaning is an important part of reducing exposure. Vacuuming with HEPA filtration, washing fabrics, and wiping surfaces with low- or VOC-free cleaners can help limit the buildup of these lingering contaminants. The takeaway Secondhand and thirdhand smoke can affect indoor air quality long after smoking occurs—often in ways that are not immediately visible. Understanding how these exposures behave is key to reducing risk in indoor environments. Observed each year on May 31, World No Tobacco Day highlights the importance of reducing tobacco-related harms—including those linked to indoor air quality and lingering smoke exposure.","

When these pollutants are inhaled, they can cause systemic harm to the human body.

In enclosed spaces, smoking can raise fine particle concentrations to levels up to 100 times higher than typical outdoor air—turning indoor environments into some of the most polluted spaces people encounter.

Smoking also directly contributes to the production of harmful gases and chemical pollutants, commonly known as volatile organic compounds (VOCs). Tobacco smoke specifically has been found to be linked to benzene, a common carcinogen that is known to cause leukemia, bone marrow damage, and anemia through long-term exposure (2).

These dynamics are especially pronounced in indoor environments, where airflow is limited and pollutants are more likely to accumulate over time.

Indoor smoking leads to long-term exposure

Smoking indoors introduces pollutants into a contained environment where they can accumulate, settle, and recirculate over time. Unlike outdoor environments, indoor spaces often lack sufficient airflow to disperse smoke quickly, allowing particles and gases to persist well beyond the act of smoking itself.

For this reason, avoiding indoor smoking completely is the most effective way to reduce exposure to both airborne and surface-bound contaminants associated with smoking.

Secondhand smoke doesn’t always dissipate outdoors

This persistence is not limited to indoor environments. It is often assumed that secondhand smoke quickly disperses outdoors and poses little risk. However, research suggests that this is not always the case—particularly in partially enclosed spaces such as patios, outdoor dining areas, and building entrances.

In these environments, secondhand smoke can reach concentrations comparable to indoor spaces where smoking is permitted. Exposure levels can vary depending on the number of smokers, proximity, and airflow conditions, with individuals downwind often experiencing the highest concentrations.

Even at a distance, smoke particles can remain detectable and irritating. In some cases, outdoor smoke can drift into adjacent indoor areas or accumulate in semi-enclosed spaces, extending exposure beyond the immediate source (3).

Studies have shown that secondhand smoke can be detected and cause irritation at distances of more than 10–20 feet from the source, particularly when individuals are positioned downwind. In outdoor settings with multiple smokers or partial enclosure, exposure levels can approach those found indoors—lasting for as long as smoking activity continues and, in some cases, persisting after the source is gone (4).

These findings challenge the assumption that outdoor smoking eliminates risk, highlighting how secondhand smoke can persist and spread across both indoor and outdoor environments.

Thirdhand smoke can further extend this exposure. Residual particles that settle onto clothing, skin, or surfaces outdoors can be carried back into indoor environments, where they continue to release harmful compounds over time. This means that even when smoking occurs outside, its effects can still persist indoors.

How smoking regulations shape indoor air quality

U.S. State and federal smoking laws have been in place since the 1960s to ensure public safety and limit indirect exposure. The Federal Cigarette Labeling and Advertising Act, enacted in July 1965, was one of the first anti-smoking laws, requiring transparent health warnings and restricting false advertising of cigarette products nationwide (5). Today, many policies extend into private spaces, as business owners take it upon themselves to limit tobacco exposure to ensure public safety.

Tobacco and smoking regulations are becoming increasingly popular worldwide as well. In 2024, Canada was the first country in the world to mandate transparent health warnings on each cigarette individually, with bold black text printed on every stick (6). Also in the same year, the United Kingdom introduced a Tobacco and Vapes Bill, which would ban those under the age of 15 from purchasing tobacco beginning 2027 (7). In a separate ruling, the United Kingdom has also banned the sell and purchase of disposable vapes to address issues in underage smoking (8).

For shared buildings and apartment complexes, anti-smoking regulations and designated smoking areas are the key to securing a healthy space for everyone, as cigarette smoke can be transported easily through open windows and air vents or stick to commonly used surfaces (9). Limiting tobacco smoke exposure doesn’t stop at smoking rules and regulations, it also depends on a building’s air filtration system.

Because tobacco smoke includes both particles and gases, reducing exposure requires more than a single approach.

How filtration can help reduce tobacco smoke exposure

Source control—preventing smoke from entering the environment in the first place—is the most effective way to reduce exposure.

HyperHEPA filtration is designed to capture 99.5% of airborne particulate as small as 0.003 microns, helping reduce tobacco smoke particles and odors.

However, tobacco smoke is not made up of particles alone—it also contains a complex mix of gases and chemical pollutants. Gas-phase filtration, such as activated carbon, is designed to adsorb volatile organic compounds (VOCs), benzene, and other harmful chemicals present in smoke. By combining particle filtration with gas-phase filtration, air purification systems can address a broader range of pollutants found in tobacco smoke.

When paired with proper ventilation and HVAC systems, these approaches can help reduce overall exposure to both particulate and chemical components of tobacco smoke.

Reducing exposure to secondhand smoke indoors

Reducing exposure to tobacco smoke often involves a combination of building-level policies and individual actions.

In homes or shared spaces where smoking occurs, reducing exposure often depends on how air moves, how surfaces are managed, and how consistently these strategies are applied:

Improving filtration and ventilation in shared indoor spaces.
Limiting indoor smoking and separating smoking areas where possible.
Using air filtration to reduce airborne smoke particles and odors
Monitoring indoor air quality to better understand exposure levels.

Addressing thirdhand smoke on surfaces

Thirdhand smoke also plays a role in ongoing exposure. Because smoke residues can accumulate on surfaces and in materials like carpets, upholstery, and clothing, regular cleaning is an important part of reducing exposure. Vacuuming with HEPA filtration, washing fabrics, and wiping surfaces with low- or VOC-free cleaners can help limit the buildup of these lingering contaminants.

The takeaway

Secondhand and thirdhand smoke can affect indoor air quality long after smoking occurs—often in ways that are not immediately visible. Understanding how these exposures behave is key to reducing risk in indoor environments.

Observed each year on May 31, World No Tobacco Day highlights the importance of reducing tobacco-related harms—including those linked to indoor air quality and lingering smoke exposure.

Detailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements. Based on evaluation results, one or more of the following solutions may be proposed: HVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork. Localized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace. Individualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone. Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.6 However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs). MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways: increased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort ventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters. NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.7 Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements. The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements.

Uncover how airborne pathogens spread and what can be done to protect yourself against them.

","Many infectious diseases, from influenza to measles, can travel through the air in microscopic particles known as aerosols. These particles can linger, move through indoor spaces, and be inhaled by others—making them a critical factor in how infections spread. The risks from airborne pathogens are ever-present, and effective strategies are essential to mitigate their impact. How infectious agents become airborne Aerosols are microscopic solid or liquid particles in air or other gases (1). Aerosols range in size from extremely small particles to larger droplets, and many are small enough to remain suspended in the air for extended periods; research has revealed that the smaller sized aerosols can remain suspended in the air for hours, making them a highly efficient vehicle for infectious agents (2). Some of the smallest airborne particles, such as PM2.5, or particulate matter measuring 2.5 micrometers or smaller, can carry viruses, bacteria, or fungi, allowing them to spread beyond close contact and infect individuals who inhale them (3)(4). Pathogens become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. Pathogens – including viruses, bacteria, and fungi – become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. When an infected person exhales, tiny droplets containing the pathogen evaporate, leaving behind even smaller particles that remain airborne. This infection process is particularly effective in indoor settings, where poor ventilation can trap and concentrate these particles, increasing the risk of transmission (5). Several factors influence how effectively airborne pathogens are spread: Particle size determines how long they stay aloft—smaller particles travel farther and remain suspended longer. Humidity affects their stability; some viruses thrive in dry air, while others persist better in humid conditions (6). Ventilation plays a crucial role. Stagnant air allows aerosols to accumulate, while proper airflow dilutes and removes them. As a group of Montreal-based teachers, scientists, and doctors demonstrated in an unofficial study conducted in 2020, increased carbon dioxide (CO2) accumulated beyond acceptable levels in classrooms through poor ventilation, which may have in turn exposed students and staff to increased risk of exposure to SARS-CoV-2 (7). The duration of exposure also matters; more time spent in contaminated air increases the likelihood of infection. All these factors combined shape the dynamics of airborne transmission. Although airborne transmission is a primary pathway, pathogens can also settle onto surfaces, where they may be transferred through contact—making both air and surface hygiene important in limiting spread. Common airborne pathogens and their risks Among the most well-known airborne threats are viruses that exploit aerosol transmission to infect new individuals. These can include: Influenza: Influenza (or flu) is a contagious respiratory illness. It relies on airborne particles to move between people, often leading to outbreaks in schools, workplaces, and public gatherings (8). Measles: Measles, typically presented by a rash, fever, cough, runny nose, and watery eyes, are extremely contagious. Measles can linger in the air for up to two hours after an infected person leaves a room, infecting those who enter later (9). SARS-CoV-2: This respiratory virus spread COVID-19 globally, with aerosols playing a key role in its transmission (10). Chickenpox: Also known as varicella-zoster, chickenpox spreads through contact, through fluids, and is airborne. (11) Bacteria also pose a significant airborne risk. Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB), spreads when infected individuals cough or sneeze, releasing aerosols that can remain infectious for hours (12). Legionella, another bacterial pathogen, thrives in water systems but becomes airborne through contaminated mist or droplets, causing severe pneumonia when inhaled (13). Where and how aerosol transmission happens Aerosol transmission can flourish in spaces with limited airflow. Hospitals, schools, and public transit systems are notable high-risk settings, where infected individuals can unknowingly expose many others to airborne pathogens. In hospitals, medical procedures such as intubation or even routine patient care can generate infectious aerosols, affecting both patients and healthcare providers. Schools, with their densely populated classrooms and shared facilities, can become epicenters during outbreaks of diseases like measles or influenza. Public transit, where ventilation is frequently inadequate, increases the risk of infection as passengers inhale recirculated air over prolonged periods. In these environments, people may be exposed to airborne pathogens even without direct contact with an infected individual. Research has shown that certain public spaces provide ideal conditions for rapid transmission. Research has shown that certain public spaces provide ideal conditions for rapid transmission. For example, a study on measles transmission in a pediatric practice demonstrated that airborne transmission occurred in an office setting, with unvaccinated infants facing an attack rate of 80% (4/5), compared to 7% (2/27) for vaccinated children (14). A 2024 study conducted in Finland found that all but one participant in a senior choir rehearsal were infected with SARS-CoV-2 (15). Computational modeling confirmed aerosol transmission as the likely cause. Environmental factors may further increase risk infection. Poor ventilation traps aerosols, allowing them to accumulate and linger. High occupancy increases the likelihood of exposure, while activities that involve heavy breathing—singing, shouting, or exercise—produce more aerosols and project them farther. Together, these factors determine how far airborne pathogens travel and how long they remain a risk. Protecting yourself and your community Reducing the risk of airborne transmission typically involves multiple layers of protection, combining environmental controls with personal precautions. Source control: Handwashing helps reduce transmission after particles settle on surfaces, complementing strategies that address airborne exposure. Ventilation: Opening windows, using exhaust fans, or upgrading to high-efficiency HVAC systems can dilute and remove infectious particles from indoor air. Carbon dioxide monitoring: Monitoring carbon dioxide serves as a practical indicator of ventilation quality. By tracking CO2, building managers and individuals can identify when ventilation needs improvement, reducing the risk of aerosol buildup and transmission. Filtration: Using a high-efficiency air purifier with advanced filtration can help reduce exposure in homes, schools, and workplaces. Masks: While loose-fitting cloth masks provide minimal defense against aerosols, wearing well-fitted KN95/FFP2 mask can help filter out 95% of airborne particles measuring down to .03 microns when worn correctly. All of these strategies combined create a robust defense against airborne threats. The takeaway By improving ventilation, monitoring indoor conditions, and using layered protection strategies, individuals and communities can better manage exposure and create safer indoor environments. This layered approach reflects a broader principle in infection prevention: reducing risk depends on combining multiple strategies rather than relying on a single intervention.

CADR measures how quickly an air purifier cleans the air. Learn how it works—and why it should be considered alongside long-term performance metrics like CCM.

","When choosing an air purifier, one of the first numbers people encounter is CADR—but it is also one of the most misunderstood. CADR, or Clean Air Delivery Rate, measures how quickly an air purifier can clean the air in a space. It is often used to compare different models, but on its own it does not reflect how an air purifier performs in real-world conditions over time. CADR focuses on short-term performance—how quickly clean air is delivered under specific conditions—rather than how long that performance can be maintained. Understanding how CADR works—and how it differs from other metrics like CCM—can make it easier to choose a system that matches both the size of a space and how performance will hold over time. What CADR actually measures CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space. In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time. CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage. CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline. The limitation of CADR: Speed vs long-term performance While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time. As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture. Many air purifiers perform well when new but lose effectiveness as filters become saturated. As a result, CADR alone gives an incomplete—or even misleading—picture of how an air purifier will perform outside of controlled test conditions. CADR vs CCM: Speed vs endurance While CADR measures speed, CCM focuses on endurance. It tracks how much pollution an air purifier can remove over time before its performance begins to decline. CCM ratings are grouped into standardized tiers for particulate matter (P) and formaldehyde (F), which indicate how much pollution an air purifier can handle before its performance begins to decline. Higher tiers represent greater long-term filtration capacity and more stable performance over time. Particulate Matter Formaldehyde P1 3000 – 5000 mg F1 300 – 600 mg P2 5000 – 8000 mg F2 600 – 1000 mg P3 8000 – 12000 mg F3 1000 – 1500 mg P4 > 12,000 mg F4 > 1500 mg In practical terms, higher P and F values indicate that an air purifier can handle more pollution before its performance drops—making these tiers a useful way to compare long-term effectiveness. For example, a system rated at P4 can remove significantly more particulate matter before performance declines than one rated at P1. Compared to CADR, CCM reflects long-term filtration performance rather than short-term speed. In practice, CADR reflects how quickly an air purifier performs under initial test conditions, while CCM provides clearer insight into how that performance holds up over time. How to evaluate air purifier performance in real-world use Understanding how an air purifier is tested can help clarify how it will perform in real-world use. If a system is too small for a space, or if performance declines over time, airborne particles may remain present. Systems with higher CCM levels are more likely to maintain consistent performance over time, which can be especially relevant for sensitive or allergy-prone groups. CCM values reflect long-term filtration capacity. Some systems are designed to maintain performance over extended use, which is reflected in higher CCM values. Some air purifiers are designed to perform strongly across both metrics. For example, systems using high-efficiency filtration, such as IQAir systems using HyperHEPA filtration, are designed to capture ultrafine particles efficiently while maintaining long-term performance. Frequently Asked Questions What is the difference between CADR and CCM? CADR measures initial short-term performance quality, calculating the rate or speed of which airborne particulate matter is cleaned and recycled. CCM measures long-term performance longevity, calculating the sheer amount of pollutant particles that are collected by an air purifier before the device begins to lose efficiency. The key difference is the short-term versus long-term measurements. What is more important to consider, CADR or CCM? While both CADR and CCM are important to consider in general, CCM provides a clearer understanding of air purifier quality and filtration over time. When choosing an air purifier, CCM values give a direct ranking on which system is going to last the longest while maintaining powerful filtration. Do all air purifiers have CADR and/or CCM ratings? Most air purifiers should have either a CADR or CCM rating listed; however, at-home calculations and trial runs can be performed to calculate the values. How is CADR measured by room? A CADR rating should be 2/3 the value of the room’s square footage that the air purifier is housed in. For instance, if a room is 180 square feet, then an air purifier with a CADR of 120 should be used. The takeaway CADR and CCM measure different aspects of air purifier performance: speed and endurance. Looking beyond CADR to include metrics like CCM provides a clearer picture of how an air purifier will perform—not just when it is new, but over time.","

CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage.

CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline.

The limitation of CADR: Speed vs long-term performance

While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time.

As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture. Many air purifiers perform well when new but lose effectiveness as filters become saturated.

As a result, CADR alone gives an incomplete—or even misleading—picture of how an air purifier will perform outside of controlled test conditions.

CADR vs CCM: Speed vs endurance

While CADR measures speed, CCM focuses on endurance. It tracks how much pollution an air purifier can remove over time before its performance begins to decline.

CCM ratings are grouped into standardized tiers for particulate matter (P) and formaldehyde (F), which indicate how much pollution an air purifier can handle before its performance begins to decline. Higher tiers represent greater long-term filtration capacity and more stable performance over time.

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

Particulate Matter	Formaldehyde
P1	3000 – 5000 mg	F1	300 – 600 mg
P2	5000 – 8000 mg	F2	600 – 1000 mg
P3	8000 – 12000 mg	F3	1000 – 1500 mg
P4	> 12,000 mg	F4	> 1500 mg

In practical terms, higher P and F values indicate that an air purifier can handle more pollution before its performance drops—making these tiers a useful way to compare long-term effectiveness. For example, a system rated at P4 can remove significantly more particulate matter before performance declines than one rated at P1.

Compared to CADR, CCM reflects long-term filtration performance rather than short-term speed.

In practice, CADR reflects how quickly an air purifier performs under initial test conditions, while CCM provides clearer insight into how that performance holds up over time.

How to evaluate air purifier performance in real-world use

Understanding how an air purifier is tested can help clarify how it will perform in real-world use. If a system is too small for a space, or if performance declines over time, airborne particles may remain present. Systems with higher CCM levels are more likely to maintain consistent performance over time, which can be especially relevant for sensitive or allergy-prone groups.

CCM values reflect long-term filtration capacity. Some systems are designed to maintain performance over extended use, which is reflected in higher CCM values.

Some air purifiers are designed to perform strongly across both metrics. For example, systems using high-efficiency filtration, such as IQAir systems using HyperHEPA filtration, are designed to capture ultrafine particles efficiently while maintaining long-term performance.

Frequently Asked Questions

What is the difference between CADR and CCM?

CADR measures initial short-term performance quality, calculating the rate or speed of which airborne particulate matter is cleaned and recycled. CCM measures long-term performance longevity, calculating the sheer amount of pollutant particles that are collected by an air purifier before the device begins to lose efficiency. The key difference is the short-term versus long-term measurements.

What is more important to consider, CADR or CCM?

While both CADR and CCM are important to consider in general, CCM provides a clearer understanding of air purifier quality and filtration over time. When choosing an air purifier, CCM values give a direct ranking on which system is going to last the longest while maintaining powerful filtration.

Do all air purifiers have CADR and/or CCM ratings?

Most air purifiers should have either a CADR or CCM rating listed; however, at-home calculations and trial runs can be performed to calculate the values.

How is CADR measured by room?

A CADR rating should be 2/3 the value of the room’s square footage that the air purifier is housed in. For instance, if a room is 180 square feet, then an air purifier with a CADR of 120 should be used.

The takeaway

CADR and CCM measure different aspects of air purifier performance: speed and endurance. Looking beyond CADR to include metrics like CCM provides a clearer picture of how an air purifier will perform—not just when it is new, but over time.

Bees are experiencing a global decline due to multiple pressures. Find out how air pollutants are impacting bee populations and what can be done to turn the tide.

","One in three bites of food we eat depends on pollinators like bees. Yet bee populations are declining, in part due to exposure to airborne pollutants such as fine particulate matter, pesticides, and microplastics (1). These pollutants harm bees and disrupt their ability to navigate, forage, and reproduce. The impact extends beyond bee populations to the ecosystems and food systems that depend on them, making it increasingly important to reduce air pollution at its source and develop creative solutions for sustainable agriculture. Why bees are essential to people and the planet Bees are a critical component of the biodiversity that supports both ecosystems and human food systems. As pollinators, they enable plants—including many crops—to reproduce by transferring pollen between flowers. It is estimated that roughly one-third of global food production depends on pollinators such as bees, making their role central to food security and agricultural stability. Beyond agriculture, bees also support broader ecosystems by sustaining wild plant populations, which in turn provide food and habitat for countless other species. Their impact extends across food systems, biodiversity, and rural livelihoods, where beekeeping remains an important economic activity in many regions. Because of this, changes in bee populations often reflect wider environmental pressures—making their health an early signal of how ecosystems are responding to pollution and other stressors (2). What pollutants are bees facing? Bees are facing numerous modern environmental pollutants that threaten their colonies and the vital services they provide. Research has demonstrated that PM2.5 – fine particulate matter measuring 2.5 microns in diameter or smaller – and ground-level ozone, both byproducts of industrial and vehicular emissions, are particularly damaging to bees (3). These pollutants can increase honey bee mortality by impairing their sense of smell. Sense of smell is essential for locating flowers and navigating back to their hives. Air pollution can also reduce pollination success by masking the floral scents that guide bees to their food sources. According to research conducted on an English black mustard farm over the summers of 2018 and 2019, flowers located close to ozone and nitrogen oxide releasing pipes were visited 90% less often than areas that were less polluted (4). A study on Giant Asian honey bee activity in India also found that bees visited flowers less often in moderate to highly polluted sites (5). Those that did experienced an increased impact on their circulatory physiology and a reduced survival rate. Neonicotinoids and other pesticides, even at trace levels, pose another threat. These chemicals target the central nervous systems of insects, leading to impaired cognition, memory loss, and disrupted foraging behavior in bees (6). Chronic exposure to pesticides affects individual bees and destabilizes entire colonies by altering the gut microbiome, which is crucial for digestion and immune function. This weakening makes bees more susceptible to parasites like Varroa mites and a host of pathogens further compromising colony health and productivity (7). Microplastics, a more recently recognized hazard, are now known to infiltrate bee habitats and even their bodies (8). Bees ingest these tiny plastic particles from the air and contaminated food sources, leading to damage in their digestive systems, weakened immune responses, and altered behaviors. Microplastics have been found in the guts of bees and in the materials wild bees use to construct their nests, exposing entire colonies to the harmful effects of plastic pollution. In addition to these factors, climate change can complicate bee survival rates as spring arrives earlier than bees are ready to feed. Drought, fire, and flooding can destroy bee foraging ranges, and Varroa mites may flourish during longer foraging seasons, placing additional pressure on bee colonies during their dormant winter months (9). These overlapping pressures help explain why bees are especially sensitive to environmental change—and why shifts in their behavior can reflect broader ecological stress. How pollutants disrupt bee biology and behavior The impact of pollutants on bees extends beyond physical harm, seeping into the behaviors and biological processes that sustain their colonies and their role as pollinators. These effects can be observed across several key systems. Air pollution makes it harder for bees to breathe and disrupts their ability to detect and follow the scent trails that lead them to flowers. Respiration and foraging behaviorAir pollution makes it harder for bees to breathe and disrupts their ability to detect and follow the scent trails to flowers. When bees cannot locate food efficiently, foraging takes longer and becomes less productive, placing additional stress on colonies. Over time, this can lead to malnutrition, reduced honey production, and, in severe cases, colony collapse. Immune functionPollutants also weaken bees’ natural defenses, leaving them vulnerable to a host of secondary threats. Pesticides and microplastics, for example, compromise the immune systems of bees, making them more susceptible to diseases and infestations by parasites such as Varroa mites. Cognition and navigationBees rely on their memory and learning abilities to efficiently gather nectar and pollen. When these faculties are compromised through reduced cognition, the entire process of pollination is put at risk. Taken together, airborne pollution can result in a 30% reduction in pollinator performance through reduced insect reproduction, increased mortality, and loss of scent (10). As these biological effects accumulate, the impact extends beyond individual species. From bees to ecosystems Bee decline is not an isolated concern. Bees’ collective health forewarns communities about broader ecological and economic impacts. Bees’ collective health forewarns communities about broader ecological and economic impacts. Bees are indispensable pollinators for a vast array of crops, and their decreased numbers have already been linked to reduced yields in these and other essential food sources. A 2020 study of 131 U.S. and Canadian farms found that apples, blueberries, and some varieties of cherries were experiencing limited yields due to reduced pollination (11). Beyond agriculture, bees play a crucial role in maintaining the health of wild ecosystems. They pollinate a wide variety of wildflowers, which in turn support countless other species, from birds and mammals to insects and microorganisms. Without bees in a region, biodiversity loss can occur, disrupting food chains and altering habitats in unpredictable but far-reaching ways. The economic effects of declining bee populations are equally important. The annual global value of pollination services is estimated to be between $235 and $577 billion (12). Bee colony declines put crop productivity at risk, leading to higher food prices, reduced agricultural output, and increased pressure on farmers to compensate for lost pollination through costly and often less effective alternatives, like hand- or machine-pollination (13). Where bees thrive or survive Bee resiliency is significantly impacted by their environment. Managed bee populations are on the decline in Europe and North America while steadily growing in Asia, especially in China (14). Yet even in China there is a difference between strong growth in honeybee populations in contrast to falling wild bee populations. In industrial agricultural zones, where pesticide use is intensive and air pollution levels are high, bees face some of their greatest challenges. Urban areas can also be hostile territories, with traffic emissions and limited green spaces further stressing pollinator populations. However, there are efforts underway to reverse course and protect bee populations. Kumamoto Prefecture in Japan is working to turn bee shortages around with a 2026 budgetary boost of 502 million yen ($3.27 million) for beekeepers (15). The money will go towards developing refrigerated facilities to reduce mite infestations. Kumamoto is the country's second largest honey producing prefecture, but populations have been declining since 2023 due to heat waves and mites. In 2025, stingless Amazonian bees in two regions of Peru were granted legal rights, the first time any insect in the world has been given such rights (16). These rainforest pollinators are in competition with European honeybees, as well as deforestation, climate change, and pesticides. These protections mean that the bees have a right to exist and can be legally represented in court cases which could impact their survival. The European Union banned neonicotinoids in 2013, then banned imports of products containing those pesticides in 2026 (17). There are varying restrictions on neonicotinoid use in U.S. states and Canadian provinces, including (18): California Colorado Connecticut Illinois Maine Maryland Massachusetts Nevada New Jersey New York Ontario Quebec Rhode Island Vermont Washington State Another way to foster bee survival is by creating bee corridors, networks of native plants and reduced-pesticide zones that provide safe passage and foraging grounds for pollinators. The National Highways Authority of India outlined plans to create the country’s first dedicated bee corridors by planting native, nectar-rich mixes of trees and plants near highways (19). When completed, the bee corridors will mirror similar projects in New England following electrical transmission lines and “B-Lines,” insect superhighways actively being mapped across the United Kingdom (20)(21). Solutions to protect bees and pollination Efforts to protect bees and pollination are taking place at multiple levels, from local communities to national policy. What individuals and communities can do Planting native flowers, reducing plastic waste, and creating “bee corridors” can support local bee populations. Community science projects, such as monitoring bee health and air quality, empower citizens to drive change. Public advocacy and policy engagement can influence stronger air quality protections. Monitor outdoor air quality to arm researchers, farmers, and policymakers with data identifying pollution sources that could impact bee populations. What farmers and researchers can do Farmers can adopt Integrated Pest Management (IPM) strategies, using biological controls and crop rotation to reduce reliance on chemical pesticides (22). Scientists are developing nutritional supplements to help bees detoxify pesticides and exploring bee breeds resistant to Varroa mites and other stressors (23)(24). What governments can do Enacting and enforcing stricter standards for PM2.5, ozone, and diesel exhaust can directly improve bee health and pollination rates. Setting such policies could help bee colonies rebound. The takeaway Bees provide an early signal of how environmental pressures, like air pollution, affect ecosystems and food systems.
