Learn about Permian Health's innovative approach to improving air quality in Gambia, using cutting-edge technology to reveal invisible pollutants and safeguard public health.

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

","In Pakistan, where vast horizons stretch beneath seemingly clear skies, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of data and awareness, the scale of the threat remains largely unseen. 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 15 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.” Pakistan's Air Quality Challenge 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. Rolling Out Pakistan’s Air Quality Network WWF-Pakistan’s initiative, which involves installing a total of air quality sensors in 15 key cities across the country, marks a critical step in Pakistan’s battle against air pollution. All 15 stations are currently up and running. 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. Air Quality Data in Action With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan. \"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.” Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives. Vision For the Future WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data. \"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution. The air quality data being gathered is more than just numbers—it’s a lifeline for communities struggling with the dangers of polluted air. “Our initiative is laying the foundation for a National Clean Air Research Centre,\" Huzaifa said. \"This will be a hub for research and data-driven policies, enabling us to tackle pollution with innovative strategies.\" “Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan.” Beyond their air quality monitoring project, the WWF-Pakistan team oversees more than 70 active environmental protection initiatives in FY 2024 across the country, ranging from clean water access and forest preservation to sustainable infrastructure development.

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. Harnessing technology for a healthier tomorrow Utilizing an AirVisual Outdoor air quality monitor, Mwendwa’s station gathers critical real-time data. “The AirVisual sensor was easy to deploy and requires little maintenance, even in our somewhat extreme conditions with limited resources,” he said.The project, though small, is already making a difference in the community. “By sharing a link to the AirVisual Platform and using the app, we can easily get our data to students nationwide, enabling them to conduct their own research on pollution,” he said. The data has also been used to inform parents with small children of the effects of poor air quality. \"They need to understand that this data can help give them a better life,\" Mwendwa said. Cultivating environmental consciousness Mwendwa envisions a future where air quality stations span Africa, fostering a culture of environmental awareness and proactive health management. “The data my station is gathering empowers students to conduct community research, highlighting pollution's impact and fostering greater understanding,” he said. “This awareness can significantly influence the general population.\"Mwendwa plans further collaborations with local governments, communities, and international bodies, with this initial project laying a foundation for sustainable environmental policies and practices. “Our goal is to illuminate the unseen threats of pollution through technology,” he said. “Providing our community, and beyond, with this data, equips them to advocate for sustainable solutions essential for a healthier future.

In what way can wax be harmful?According to a 2017 study in the International Journal of Tropical Disease and Health, paraffin candles emit pollutants that can threaten human health and shouldn’t be burned in enclosed areas (1).Most candles are made from paraffin, a petroleum byproduct. To create paraffin wax candles, petroleum waste is chemically bleached, deodorized, and made into wax. When burned, paraffin wax can release toxicvolatile organic compounds (VOCs) into the air, including known carcinogens like: alkenes acetone benzene toluene These are the same chemicals found in diesel fuel emissions and are known to cause allergies, asthma attacks, and skin problems.A 2005 study published by the University of South Florida showed that candles made of paraffin wax emit low levels of benzene even when they are not lit (2).Is burning candles bad for you?In addition to releasing toxic chemicals, burning paraffin wax produces soot composed of particulate matter such as, PM2.5 and ultrafine particles that can remain suspended in the air for hours. According to the University of South Florida study, ultrafine soot particles are similar to diesel exhaust in both their size and composition. They penetrate deeply into the lungs and are absorbed into the blood stream (3).A 2000 study conducted by the U.S. Environmental Protection Agency showed that soot emissions from candles are significantly higher after wax breakthrough occurs and when a candle is smoldering (4).Ultrafine particles are associated with severe health issues, including: allergies asthma COPD (5) respiratory tract infections heart attacks strokes cancer So, are candles bad for your health? Not all candles produce the same amount of air pollutants. A 2002 study published in theJournal of the American Oil Chemists’ Society found that soywax, much like beeswax candles, burned at a significantly lower rate and resulted in less soot than paraffin candles (6).Chemical fragrancesAnother problem with scented candles is that the chemicals they use to create a pleasing aroma are generally far from wholesome.Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature.Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature. Commonly emitted VOCs related to the scent in candles include (7): formaldehyde petroleum distillates limonene alcohol esters These harmful chemicals can cause health problems, such as: headaches dizziness allergy symptoms asthma attacks respiratory tract infections cancer Cored wicksMany candles have cored wicks made from cotton that are wrapped around a metal support. The design helps keep the wick from falling over into the wax. This is especially useful for scented candles because the fragrance oils soften the wax and allow non-cored wicks to go limp.Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). Zinc and tin have been used as a substitute since the ban.All metal-core wicks release trace amounts of heavy metals into the air when they are burned.However, all metal-core wicks release trace amounts of heavy metals into the air when they are burned. Wicks with zinc and tin cores can still release small amounts of lead particles (9,10).Safer alternativesTo limit soot stains and poor air quality in your home, you should avoid or restrict the use of candles (11).If you still crave the pleasant ambiance and aroma of scented candles, here are safer ways to scent the air: Use essential oils for fragrance.Essential oils can be placed in a diffuser or in bathwater to create a desired aroma. Simmer spices.Place spices such as cinnamon sticks, cloves, and nutmeg in a pot of water and let it simmer on the stove. Create potpourri.Dried items such as flowers, berries, fruit rinds, wood chips, and spices can be placed in bowls or fabric bags and placed around your home. The takeawayLighting scented candles may seem like a relaxing way to enjoy your home. But burning scented candles releases VOC pollutants and worsens your home’s indoor air quality. Although fragrances from safer alternatives like essential oils can be pleasant, trulyclean air smells like nothing at all.","

Are scented candles bad for you?

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

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

Paraffin wax

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

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

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

alkenes
acetone
benzene
toluene

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

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

Is burning candles bad for you?

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

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

Ultrafine particles are associated with severe health issues, including:

allergies

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

Chemical fragrances

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

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

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

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

headaches
dizziness
allergy symptoms
asthma attacks
respiratory tract infections
cancer

Cored wicks

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

Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). Zinc and tin have been used as a substitute since the ban.

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

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

Safer alternatives

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

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

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

The takeaway

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

Himalayan salt lamps DO NOT purify indoor air.

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

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

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

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

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

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

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

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

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

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

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

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

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

There are two main types of ozone:

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

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

A few hours or less after rush hour begins and the sun begins to rise, you’ll start to notice a visible layer of haze build up. This is ground-level ozone, and even though it’s a typical feature of modern life, extensive research shows that it causes a plethora of immediate symptoms, including:

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

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

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

So what’s so special about Himalayan salt?

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

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

Salt lamps have been proposed for use in treatments for conditions like chronic obstructive pulmonary disease (COPD) because of their purported therapeutic effects on your respiratory system.

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

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

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

The home air purifier market has undergone many shifts and starts in its decades-long history as an affordable solution for indoor air quality. Along with those shifts have been seemingly ground breaking advancements in filtration technologies that may seem like the next revolution in air purification.

But not all air purifiers safely clean the air.

Not all air purifiers safely clean the air.

Let's take an evidence-based approach to the industry and separate the fact from the fiction.

What should I look for in an air purifier?

Before we examine the various air purifiers on the market with a critical eye, it’s essential to have a solid understanding of what does make a good air purifier.

$\"Air$

1. HEPA filters are the standard for the industry.

What is a HEPA filter?

High-efficiency particulate air (HEPA) filters capture airborne particles from moving air using a dense, random arrangement of fibers. HEPA filters use the physics of particles moving through air to yank them out of the air flow. Their operation is simple but extremely effective, and HEPA filters are now standard issue for almost every air purifier on the market.

But it wasn’t always that way.

Air purifiers have been around for well over a century. The first air purification systems appeared in the 1850s in charcoal-based masks used by coal miners. They were designed to keep toxic dust out of their lungs. The technology was so successful that, less than twenty years later, respirators were added to these types of masks to protect firefighters from breathing in smoke chemicals and pollutants (1).

Beginning in the 1940s, the United States Atomic Energy Commission started experimenting with high-efficiency particulate arrestance, better known now as HEPA, as a method of shielding soldiers from atomic radiation on World War II battlefields (2).

HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants.

In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3).

Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns.

The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems.

Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size.

2. Not all air purifier designs are created equal.

All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA.

To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4).

The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5).

So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6).

Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less.

Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media.

3. Concerned about gas and odors? Go beyond HEPA.

While HyperHEPA filters are great at getting particles out of the air, they do NOT take gases and odors out of the air.

Unlike particles, the molecules that comprise gases, odors, and volatile organic compounds (VOCs) are not solid and will float through even the densest HyperHEPA filters. That’s where activated carbon filters come in.

How do these filters work? It’s simpler than you might think:

Chunks of carbon material (like charcoal) are exposed to high concentrations of oxygen.
Countless pores open on the carbon surface, increasing the carbon surface area enormously. At this point, a pound of activated carbon can have the same surface area as 100 football fields.
Several pounds of activated carbon are arranged in a flat “bed” and packaged in a proprietary filter design (such as IQAir’s V5 Cell gas and odor control filter).
Air passes through the activated carbon bed.
Gas, chemical, and VOC molecules are adsorbed into the carbon pores, meaning that they chemically bond to the extensive charcoal surface area.

Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes (7)(8).

Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes.

Some air purifiers are designed to maximize activated carbon in case you’re more concerned about, for example, gases from cooking or odors from pets than about particle pollution in your home. IQAir’s GC MultiGas is built for such a purpose—while carbon filters generally use a few pounds of carbon, the GC MultiGas contains 12 pounds of activated carbon as well as impregnated alumina, providing well over 1200 football fields worth of surface area for gas and VOC molecules to adsorb to.

The takeaway

Now you know that the elements of a good air purifier are:

\nHyperHEPA media for particle filtration
\nNo system leakage due to sealed filter and purifier housing
\nActivated carbon for gas and odor filtration

But we're not done yet. Just as important to know is what not to look for in an air purifier.

What should I avoid in an air purifier?

When considering air purifiers, some people wonder about their effectiveness and even potential risks. Question often arise, such as \"Do air purifiers work?\" or \"Are air purifiers effective?\" The answer is that while some air cleaning methods can remove particles and pollutants from the air, their capabilities are often limited.

But it's not just about effectiveness. People also ask, \"Are air purifiers bad for you?\" This concern arises from potential hidden costs to your health. It's important to be aware of inefficiencies and any potential risks associated with the air purifier you're considering before making a purchase.

So, if you're in the market for an air purifier, remember to ask yourself whether it will be effective at removing pollutants and particles from the air, and whether it poses any risks to your health.

Ionizer air purifiers

Ionizers are purported to purify air by sending out negatively charged ions (anions) that attract positively charged pollution particles (cations), causing them to leave the air and stick to surfaces like ceilings, walls, and furniture.

Many popular air purifiers use ionization technology, also called negative ionization, as a central component of their operation. Research suggests that ionizers can help stop potentially infectious molds and bacteria from spreading in sterile environments like dental clinics and hospitals (9)(10).

But there are two critical downsides to ionization (11)(12):

\nIonizer air purifiersdon’t get rid of pollutants. Particles charged by negative ions aren’t removed from the air—they merely stick to surfaces nearby. This includes surfaces inside your airways, such as your windpipe and alveoli, the sacs of air in your lungs. Pollutant build-up can cause heart, lung, and other respiratory conditions.
\nIonizer air purifierscan generate harmful ozone. Ionizers produce ozone (O3) that can build up to dangerous levels indoors. At even low levels, indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb (the organ that helps your brain process odors), and even be fatal at high concentrations. \n

Indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb, and even be fatal at high concentrations.

Verdict

Don't buy an ionizer air purifier.They don’t remove particles from the air, and the ozone they produce can have harmful side effects, even if the purifier claims that they only charge the particles “a little bit.”

Ozone Generators

It’s worth saying again: ozone is TERRIBLE for you, especially indoor ozone build-up. The health concerns are serious enough that in 2017, California banned the use of ozonehome air purifiers (13).

Ozone generators use a process called corona discharge to release ozone molecules into the air. When an ozone molecule intermingles with a particle or gas molecule, an ozone atom clings to the other molecule and blows it up in a process known as oxidation. Oxidation in the atmosphere after a lightning strike is also what makes the air smell so distinct after a thunderstorm.

However, ozone generators do little to clean air and are quite bad for you. Here’s just a short (and far from complete) list of reasons why (14)(15)(16)(17)(18):

\nOzone can take years to fully clear even a small room of gases.
\nOzone reactions can introduce ultrafine particles (UFPs) into the air.UFPs can get into your lungs and your bloodstream, causing heart disease and even stunting lung development in children.
\nIndoor ozone levels can rise five to ten times above recommended limits,which range from 0.05 to 0.1 parts per million (ppm), because of a lack of ventilation and in combination with outdoor ozone that seeps indoors.To put this in perspective, those who are sensitive to ozone, such as children, people with asthma, and pets, start experiencing health effects at only 0.01 ppm. Even a “safe” ozone generator that emits a small amount of ozone can quickly trigger potentially life-threatening ailments like asthma attacks.

Verdict

Don’t buy an ozone generator. They’re NOT air purifiers. Not only do they fail to clean your air, they hurt you and the most vulnerable in your home: your children and your pets.

UV Light Purifiers

Ultraviolet (UV) light is often used to disinfect equipment in hospitals and prevent the spread of harmful strains of bacteria and viruses (19)(20).

One of the most common UV purification methods is called ultraviolet germicidal irradiation, or UVGI.

In UVGI, intense UV lights are shined on bacteria and viruses, damaging their DNA beyond repair. Bacterial cells and viruses then shut themselves down because they can no longer function. This is called apoptosis, or programmed cell death, which effectively destroys their ability to cause infections (21).

But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26):

\nBacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful.
\nSome bacteria can come back to life and become infectious again even after being disinfected by UV light.
\nUV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5.
Many UV air purifiers produce ozone.
\nUV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer.

Air treated with UV light can still be full of harmful particulate matter.

Verdict

Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated.

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

Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. 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.

","Is the air quality good in Chile? As of June 15, 2026, air quality in central Chile remains poor, with major cities experiencing \"unhealthy\" levels and high PM2.5 concentrations, posing health risks to residents, especially children and the elderly. By 12:30 AM (Chile Standard Time, GMT-4), some urban centers recorded AQI readings above 150, prompting health warnings. Residents are advised to limit prolonged outdoor activity, wear masks outdoors, keep windows closed, and use air purifiers indoors. While conditions fluctuate throughout the day, central Chile regularly experiences seasonal pollution episodes during the colder months. Studies conducted in Santiago and Temuco have confirmed that for every 50 µg/m³ increase in PM10 levels in 24 hours, there is an average increase of about 3% in general mortality, with increases in PM10 also associated with higher respiratory and cardiovascular mortality (1).

Mean PM2.5 levels during the cold season from April through September are more than twice as high as those in the warm season from October through March.

Firewood smoke from residential heating is responsible for more than 90% of PM2.5 emissions in cities located between the O'Higgins and Aysén regions, where indiscriminate use of firewood for heating is the primary driver of seasonal air quality crises (4). In Santiago, the situation is compounded by the city's position between the Andes and the Cordillera de la Costa, which creates a pocket where stagnant air accumulates and disperses slowly, while vehicle exhaust, fossil fuel power generation, and construction dust add a persistent pollution base throughout the year.

A severe heatwave is affecting India, Pakistan and Afghanistan, with temperatures exceeding 100°F (38°C) across the region. Learn more about ongoing heat risks and alerts.

","Why is there a heatwave in South Asia? As of June 15, 2026, a prolonged heatwave is affecting South Asia, driven by strong high-pressure systems that trap hot air near the surface. Temperatures in India, Pakistan and Afghanistan have soared well above seasonal averages, with some areas approaching or exceeding 45-50 degrees Celsius (113-122 degrees Fahrenheit) (1). The heat arrived earlier than the typical May-June season. High-pressure systems dominate, trapping hot air near the surface like a dome, preventing it from rising and cooling, while sinking air compresses, warms, and blocks clouds, allowing relentless solar heating (2). Climate scientists say meteorological conditions are up to 4°C warmer than in the past, mostly ascribing the increased heat to human-driven climate change. Which cities or areas are affected by the heatwave? Several major cities across South Asia are experiencing extreme heat during this heatwave event, some of the affected include: India: Ahmedabad, Agra, Asansol, Barmer, Bikaner, Delhi, Ludhiana, Madurai, Nagpur, Nanded, Nellore, Prayagraj, Raipur and Sirsa. Pakistan: Bahawalpur, Dadu, Dalbandin, Dera Ismail Khan, Faisalabad, Gujranwala, Hyderabad, Layyah, Multan, Peshawar, Rahim Yar Khan, Sahiwal, Sibi, Sukkur and Turbat. Afghanistan: Farah, Jalalabad, Kandahar, Lashkar Gah, Mazar-i-Sharif and Mirabad. How long will the heatwave last? The heatwave began in early April 2026 and is expected to persist through the summer months across parts of South Asia. Forecasts for India and Pakistan indicate above-normal heatwave activity through the April–June period, while Afghanistan is also expected to experience prolonged extreme heat, particularly in southern regions where temperatures commonly reach 36–43°C (97–109°F) (3). Temperatures above 100°F (38°C) are likely to continue across much of the region until seasonal monsoon rainfall brings gradual relief later in the summer. The strong El Niño affecting the region this summer is contributing to more intense, longer-lasting heat waves and dry weather across South Asia (4). Are there any alerts in place? Multiple heat alerts are active across South Asia. Several regions in India were placed under orange alert for heatwave conditions, with authorities warning of increased heat-related illnesses and directing hospitals and livestock services to prepare accordingly (5). In Pakistan, the Pakistan Meteorological Department (PMD) warned that heatwave conditions are expected to persist and advised residents to avoid direct sunlight and stay hydrated. Both countries have Heat Action Plans coordinated through disaster management authorities (6). Afghanistan's extreme summer heat typically affects outdoor workers and vulnerable populations, though formal heat-specific alert systems are limited compared to neighboring countries. Residents are advised to stay in air-conditioned spaces, avoid direct sun exposure, drink fluids, and check on elderly individuals. Outdoor workers should reschedule activities to cooler hours.","

The earth’s changing climate is creating more desert, and with its accompanying dust, more health risks. Find out how desertification affects our health and environment.

","Desertification is transforming once-productive land into dry, degraded terrain at an accelerating rate. The process is increasing globally due to climate change and rising temperatures. Transforming soil to desert creates sand and dust which can then be carried over borders, continents, and oceans to impact ecosystems and affect human health far from its source. Dust lifted from one region can ultimately affect the air quality, ecosystems, and public health of another. Desertification is transforming once-productive land into dry, degraded terrain at an accelerating rate. The science and health impacts of dust Desertification is accelerating through climate change, over-farming, and water depletion. With these changes comes an increased risk to human health, economic upset, greater social injustice, and disrupted ecosystems. How climate change intensifies dustWith increased global temperatures associated with human-caused climate change, longer lasting and more intense droughts are an increasing reality. When drought parches the soil, winds sweep up particulate matter, creating dust storms that can traverse continents, blanketing cities and countries, and reddening skies. Large dust plumes can also affect the climate in unexpected ways. Plumes can reflect sunlight back into space, temporarily cooling the atmosphere; they also absorb heat, altering temperature and precipitation patterns (1). Meanwhile, dust deposited on snow and ice darkens their surfaces, accelerating melt rates and contributing to rising sea levels (2). Beyond affecting air quality and visibility, dust can also reshape the environments where it settles. Dust’s impact on ecosystemsDust plays a paradoxical role in ecosystems. While it fertilizes rainforests and oceans with nutrients like phosphorus, it can also smother coral reefs, alter soil composition, and change rainfall distribution (3)(4). In this way, dust can act as both a nutrient source and a pollutant, depending on where it travels and where it settles. In the Amazon, dust from the Sahara Desert helps sustain biodiversity, but in marine environments, it can fuel harmful algal blooms that devastate aquatic life (5)(6). On land, dust deposition can change soil chemistry, favoring some plant species over others and reshaping entire landscapes (7). It can also affect photosynthesis, respiration, transpiration, and even injure plants or make them more vulnerable to other pollutants. Dust and air qualityDust can affect air quality both locally and thousands of miles from its origin. The way it behaves depends partly on how it is generated, but also on atmospheric conditions and the winds that carry it. Dust can come from multiple local, human-caused sources, including construction, demolition, agricultural practices, industrial processes, landscaping, vehicle traffic from road surfaces, and even walking on unpaved paths (8). Some short, intense dust storms like haboobs may remain a localized anomaly appearing as a wall of dust engulfing cities. However, unlike larger plumes which may travel great distances, haboobs tend to last only about 10 to 30 minutes (9). Air quality measurements of airborne pollutants, especially PM2.5 and PM10, can sharply rise during a haboob. In very large, naturally occurring dust plumes, dust is lifted and carried high into the atmosphere by strong winds. Such plumes may gradually disperse and deposit dust, coating surfaces like homes, cars, fields, and vegetation. Arid and desert regions can generate some of the most significant dust plumes, and geographic features can work to magnify its impact. For example, the Bodélé Depression in the Sahara Desert is considered the most intense source of airborne dust on the planet. This is because strong winds blow dust through the basin and into what is effectively a wind tunnel formed by mountains and sand dunes. That dust can then cross North Africa and impact the air quality of millions of people living in West Africa or deep into Northern Europe (10). Dust and human healthDust storms can carry more than soil particles alone. Airborne dust may also contain biomaterials, heavy metals, and microplastics, all of which can affect human health in different ways (11)(12)(13). Fine particulate matter found in dust, PM2.5, poses the greatest concern for human health. PM2.5, or particulate matter measuring 2.5 microns or less, can be inhaled deeply into the lungs. From there, PM2.5 can trigger asthma, chronic obstructive pulmonary disease (COPD), and lung infections like Valley Fever, caused by Coccidioides spores in U.S. Southwest dust (14). These fine particles can enter the bloodstream, increasing the risk of heart attacks and strokes (15). Dust storms also often correlate with spikes in hospital visits for respiratory distress (16). Atmospheric scientists at NASA’s Goddard Space Flight Center estimated that 22% of premature deaths connected to PM2.5 in 2019 could be directly linked to dust (17). These impacts are often felt most strongly in regions already facing limited healthcare access and environmental stress. Many of those deaths occurred in regions impacted by deserts and dust spanning from West Africa to East Asia. Economic and social impacts of dustDesertification and dust’s long reach can strain economies and societies. Dust storms ground flights, reduce solar energy output, and damage crops. Estimated annual crop losses from dust can range in the millions for Mongolia or as high as $154 billion for the United States (18)(19). Healthcare systems face increased costs from treating dust-related illnesses. Communities may grapple with displaced livelihoods as farmland soil degrades and turns to desert. This desertification can also harm pastoral communities, as livestock are unable to graze or drink. Where desertification is accelerating Desertification is a global issue. For instance, thirteen European Union Member States have reported that parts of their nations were being affected by desertification (20). Bulgaria, Hungary, Spain, and Italy are among the countries most impacted. Desertification in the U.S. SouthwestIn the arid landscapes of Arizona, Southern California, Nevada, New Mexico, and Utah, dust storms and haboobs are a growing air quality concern. The combination of prolonged drought, overgrazing, and urban expansion has left the soil vulnerable to wind erosion (21). During dust events, hospitals in these states report increased admissions for asthma attacks, pneumonia, and motor vehicle accidents caused by reduced visibility (22). The situation is compounded by the presence of Coccidioides spores in the soil, which become airborne during storms and infect those who inhale them (23). The spores can lead to Valley fever, a fungal infection that can lead to cough, fever, exhaustion, and chest pain. Saharan dust plumesEvery year, massive plumes of dust from the El Djouf region of the western Sahara Desert travel over 5,000 miles across the Atlantic, reaching the Caribbean, the southeastern United States, and the Amazon rainforest (24). These plumes, often visible from space, carry millions of tons of fine particles. In affected areas, Saharan dust events lead to hazardous air quality, triggering asthma attacks and other respiratory issues. The Great Green Wall was launched in 2007 in response to North Africa’s increasing desertification (25). In the Sahel region bordering the Sahara Desert – a semi-arid, savannah region that transitions between desert and greener farmland and forested lands – drought and intense heat have disrupted food production and fueled conflict. The Great Green Wall project involves planting native, ecologically appropriate trees and plants. It’s also renewing degraded lands, creating new agricultural opportunities, and bringing life back to communities living on the periphery of food security. Arabian Peninsula stormsThe Arabian Desert, along with arid regions in Iraq and Syria, is a major source of naturally occurring dust storms in the Arabian Peninsula, especially in the summer months. But dust events can take place any time of year, even in winter. There are two main sources of dust in the region, including the Mesopotamian flood plain in southern Iraq and the “Rub al-Khali” (or Empty Quarter) in Saudi Arabia (26). Dust can also enter the region from neighboring deserts, like the Sahara. In the region, chronic exposure to dust is linked to higher rates of respiratory diseases and cardiovascular problems than most other regions of the world, with the exception of North Africa (27). Regional dust storms also reduce visibility, causing traffic accidents and grounding flights. Dust from this region often travels beyond national borders, affecting air quality in Western Asia and even parts of South Asia, creating a shared challenge for the entire region. Some countries are now investing heavily in long-term containment and restoration efforts. China's containment planDesertification impacts the dry North China Plain. 24.7% of China’s lands have transformed through desertification, affecting 400 million people (28). In response, China has implemented one of the world’s most ambitious desertification containment programs, combining large-scale afforestation, strict land-use policies, and technological innovation. Through initiatives like the Three-North Shelter Forest Program—often called the \"Great Green Wall of China\"—the government has planted billions of trees and shrubs to stabilize soil, reduce dust storms, and restore degraded land. China’s efforts to green the edges of the Taklamakan Desert in the country’s west has created a carbon sink, which is both reducing desertification’s spread and helping to reduce carbon dioxide in the atmosphere (29). China’s government has also worked to reduce desertification in the north through policies countering overcultivation and overgrazing, while turning to supportive technological innovations, like expanding solar panel coverage. Beyond generating clean energy, solar panels can provide shade for desert-adapted plants and shrubs that help stabilize the soil and slow desert expansion (30). Conclusion Reducing the impact of desertification and airborne dust requires coordinated action across land management, public health, and environmental policy. Dust knows no borders. Particles lifted by desertification and drought in one region can travel thousands of miles, affecting health, economies, and ecosystems far away. Because dust travels across borders and continents, reducing its impacts requires coordinated action that extends beyond any one region. Restoring degraded lands, investing in public health infrastructure, and early warning systems can all serve to mitigate the worst harm caused by desertification. As desertification expands, understanding how dust moves—and how it affects health, ecosystems, and infrastructure—is becoming an increasingly important part of adapting to a changing climate.","

Discover the most effective place to put your air purifier in the bedroom.

","The best place to put an air purifier in a bedroom is close enough to improve the air you breathe while sleeping, but positioned so clean air can circulate freely throughout the room (1). Because people spend long, uninterrupted hours in bedrooms, air purifier placement can influence how effectively airborne particles and allergens are removed from the sleeping environment. Clean air and the sleeping environment Bedrooms are where people typically spend the longest uninterrupted periods indoors, making them critical spaces for clean air—especially for those with allergies, asthma, or sensitivities to dust, pet dander, or outdoor pollutants. Because people spend extended periods breathing the same indoor air while sleeping, air purifier placement can influence how effectively these particles are removed from the sleeping environment overnight. Reducing indoor pollution sources, improving airflow and ventilation by opening windows when outdoor air quality allows, and using high-efficiency filtration can all influence how particles accumulate indoors. For example, reducing the use of heavily scented products, improving ventilation when outdoor air quality is good, and limiting indoor smoke or dust sources can help reduce the amount of airborne particles circulating through a bedroom. Why airflow matters in a bedroom Air purifiers work by pulling polluted air through a filtration system and recirculating cleaned air back into the room. When airflow is blocked by walls, furniture, or bedding, particles can remain concentrated in parts of the room instead of circulating toward the purifier. Because airflow influences how particles move through a bedroom, purifier placement can affect how efficiently airborne particles are removed from the sleeping environment. Common mistakes to avoid in bedroom purifier placement Many people unknowingly reduce their air purifier’s effectiveness by making these placement errors: In a corner or behind furniture: This blocks airflow and limits the purifier’s reach. Keep it in an open area where air can circulate freely. Too close to electronics or heat sources: Avoid placing it near TVs, lamps, or heating vents, as heat can affect performance or pose a safety risk. Near open windows during high-pollution times: While ventilation is good, outdoor allergens or smog can enter and overwhelm the purifier. Close windows during allergy season, wildfires, or peak traffic hours. Ignoring filter maintenance: A clogged filter reduces airflow and efficiency. Check and replace filters as recommended, especially in high-dust environments. If your bedroom is large or irregularly shaped, consider a purifier with strong airflow or use a second unit to ensure even coverage. For children’s rooms, place the purifier out of reach but where it can still circulate air effectively. Frequently Asked Questions Should I run my air purifier all night in the bedroom? Yes. Running it continuously on a low or night mode ensures clean air throughout your sleep, which is especially beneficial for allergy or asthma sufferers. Most modern purifiers are quiet enough not to disrupt rest. Can I place the air purifier on the floor next to my bed? Yes. Placing an air purifier on the floor near the bed can be effective, provided airflow is not blocked by furniture or bedding. Keep enough space around the purifier for air to circulate freely. How far from the bed should the air purifier be? Aim for 3–6 feet away, positioned so clean air flows toward your breathing zone without blowing directly on you. This balances effectiveness and comfort. Does the air purifier need to be centered in the room? Not necessarily. Prioritize placing it near your bed but with unobstructed airflow. For larger bedrooms, a central location can help, but proximity to your sleeping area is most important. Can I use an air purifier in a small bedroom? Yes. Choose a model sized for your room and place it where airflow isn’t blocked. Even in smaller bedrooms, compact air purifiers can help improve air quality when positioned with unobstructed airflow. Conclusion Air purifier placement can influence how effectively fine particles and allergens are removed from the air you breathe while sleeping. Positioning the purifier where airflow remains unobstructed helps improve circulation and reduce indoor particle buildup over time. Indoor air quality is often managed through a combination of source control, ventilation, and filtration. Combined with regular cleaning and reduced indoor pollution sources, proper air purifier placement can help create a cleaner sleeping environment and improve the air circulating through your breathing zone overnight.","

Can I use an air purifier in a small bedroom?

Yes. Choose a model sized for your room and place it where airflow isn’t blocked. Even in smaller bedrooms, compact air purifiers can help improve air quality when positioned with unobstructed airflow.

Conclusion

Air purifier placement can influence how effectively fine particles and allergens are removed from the air you breathe while sleeping. Positioning the purifier where airflow remains unobstructed helps improve circulation and reduce indoor particle buildup over time.

Indoor air quality is often managed through a combination of source control, ventilation, and filtration. Combined with regular cleaning and reduced indoor pollution sources, proper air purifier placement can help create a cleaner sleeping environment and improve the air circulating through your breathing zone overnight.

Get to know the science behind air cleaning technology, and how a high-performance air purifier can capture PM2.5.

","Yes, air purifiers can significantly reduce indoor PM2.5 levels. Studies have shown that high-efficiency filtration can lower concentrations of fine particulate matter indoors (1). What is PM2.5? PM2.5 refers to fine airborne particles measuring 2.5 microns or smaller—small enough to penetrate deep into the lungs and even enter the bloodstream. These particles come from sources like vehicle emissions, wildfire smoke, industrial pollution, and cooking. Air purifiers with high-efficiency filtration, particularly HyperHEPA filtration, are designed to capture and remove PM2.5, improving indoor air quality and reducing health risks associated with long-term exposure, such as respiratory issues, cardiovascular disease, and aggravated allergies or asthma. How PM2.5 builds up indoors PM2.5 does not need to originate indoors to affect indoor air quality. Fine particles from outdoor pollution can enter through doors, windows, ventilation systems, and small gaps in buildings. Indoor activities such as cooking, candles, smoking, and cleaning can also generate PM2.5. Because these particles are extremely small and lightweight, they can remain suspended in the air and continue circulating long after they are produced. How air purifiers reduce indoor PM2.5 Air purifiers combat PM2.5 using advanced filtration technologies. The primary filtration layer is typically a HEPA filter, which physically traps fine particles as air passes through. HyperHEPA filters are even more effective, capturing ultrafine particles down to 0.003 microns—far smaller than PM2.5—with an efficiency of at least 99.5%. This makes them effective at reducing not just PM2.5, but also ultrafine particles from sources like wildfires or vehicle exhaust. Many air purifiers also include a pre-filter to capture larger particles, extending the life of the main filter, and an activated carbon filter to address gases and odors that often accompany PM2.5 pollution. Smart purifiers with real-time air quality sensors can automatically adjust fan speeds to respond to spikes in PM2.5, helping respond to changing indoor conditions during high-pollution events like wildfires or heavy traffic periods. The health impact of reducing indoor PM2.5 Long-term exposure to PM2.5 has been linked to respiratory disease, cardiovascular disease, and other chronic health conditions. By lowering indoor PM2.5 levels, air purifiers help mitigate these risks, especially for vulnerable groups like children, the elderly, and those with pre-existing conditions. For maximum protection, place the purifier in rooms where you spend the most time, such as bedrooms or living areas, and run it continuously. Sealing windows and doors during high-pollution events further enhances the purifier’s effectiveness by preventing outdoor PM2.5 from entering your home. Frequently Asked Questions Can an air purifier remove all PM2.5 from indoor air?While no purifier can eliminate 100% of PM2.5, models with HyperHEPA filtration capture up to 99.5% of PM2.5 and can significantly improve indoor air quality. How quickly can an air purifier lower PM2.5 levels?Most purifiers begin reducing PM2.5 within minutes, but it may take a few hours to achieve maximum reduction, depending on room size, purifier strength, and initial pollution levels. Should I run my air purifier 24/7 to combat PM2.5?Yes. Continuous operation ensures PM2.5 levels stay low, especially in high-pollution areas or during events like wildfires. Use auto mode to balance energy use and purification. Can air purifiers help with wildfire smoke?Yes. Wildfire smoke is rich in PM2.5, and HyperHEPA air purifiers are effective at removing these particles. Close windows and run the purifier on high during smoke events for best results. Conclusion PM2.5 does not need to originate indoors to affect indoor air quality.

Managing the flooding remains challenging as heavy rainfall continues across affected regions. Rescue operations are ongoing, with Japanese authorities monitoring river levels and issuing updated weather advisories. Tropical Storm Jangmi was moving northeast with maximum sustained winds of 90 kph (55 mph) as of Wednesday morning. Heavy rain paralyzes street traffic, suspended train services, and knocked out power to more than 5,000 homes in the Tokyo region (2). Are there any evacuation orders or alerts in place? Japan has issued highest-level flood warnings across central and eastern regions, urging residents to move to higher ground for safety. Authorities urged approximately 370,000 people across swaths of the country from Shikoku island in western Japan to Tokyo to evacuate. Residents near rivers and in vulnerable mountainous areas were strongly advised to take shelter. Schools in Tokyo and surrounding areas have closed, while train services remain suspended or delayed. Authorities continue monitoring conditions and rolling updates as rainfall persists through June 4. How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration. Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly. If you experience persistent mold-related health issues or have concerns about extensive mold growth, consult with a medical professional or a mold remediation specialist.","

Learn where Code Orange air quality alerts are in effect across the United States and when ozone levels are expected to improve.

","Is the air quality good in the affected locations? On June 5, 2026, air quality is not considered good across multiple regions of the United States due to elevated ground-level ozone concentrations (1). Code Orange Air Quality Alerts and Air Quality Action Days have been issued for parts of North Carolina, South Carolina, Maryland, Virginia, Georgia, Delaware, New Jersey, Pennsylvania, New York, Connecticut, Indiana, Ohio, and Kentucky. These alerts indicate that air pollution levels may become unhealthy for sensitive groups, including children, older adults, and people with asthma, heart disease, or other respiratory conditions. Areas under alert include: Charlotte, Concord, and Kannapolis, North Carolina Winston-Salem, Greensboro, and High Point, North Carolina Greenville and Spartanburg, South Carolina Atlanta, Georgia Northern Virginia District of Columbia Baltimore and Annapolis, Maryland Philadelphia metropolitan area New York City metropolitan area Parts of Connecticut, Delaware, New Jersey, Indiana, Ohio, and Kentucky The air quality alerts are being issued from numerous state-level and county-level environmental departments, like the North Carolina Department of Environmental Quality and the Forsyth County Office of Environmental Assistance and Protection in Winson Salem, North Carolina (2). Residents in these areas should monitor local air quality conditions and limit prolonged or strenuous outdoor activity during the afternoon and early evening hours, when ozone concentrations are typically highest. When will air quality improve in the affected locations? Air quality is expected to improve after the current alerts expire, most of which end during the evening hours of June 5, 2026, or by midnight local time. Ground-level ozone concentrations generally decrease after sunset as temperatures cool and the sunlight needed for ozone formation diminishes. Improved atmospheric mixing and changing weather conditions may also help disperse pollutants. However, additional alerts may be issued if similar weather patterns persist. Residents should continue monitoring local forecasts and air quality advisories from state environmental agencies. What is causing poor air quality in the affected locations? The primary cause of poor air quality across these regions is elevated ground-level ozone formation. Several atmospheric conditions are contributing to ozone accumulation: Strong sunshine that accelerates ozone-producing chemical reactions High pressure systems creating stagnant air conditions Light winds that limit pollutant dispersion Existing emissions from vehicles, industrial activities, and other pollution sources Warm temperatures that enhance ozone formation In South Carolina, officials specifically cited dominant high pressure, minimal cloud cover, low atmospheric moisture, light winds, and poor pollutant dispersion as key factors contributing to elevated ozone levels.

The air quality alerts are being issued from numerous state-level and county-level environmental departments, like the North Carolina Department of Environmental Quality and the Forsyth County Office of Environmental Assistance and Protection in Winson Salem, North Carolina (2).

Residents in these areas should monitor local air quality conditions and limit prolonged or strenuous outdoor activity during the afternoon and early evening hours, when ozone concentrations are typically highest.

When will air quality improve in the affected locations?

Air quality is expected to improve after the current alerts expire, most of which end during the evening hours of June 5, 2026, or by midnight local time.

Ground-level ozone concentrations generally decrease after sunset as temperatures cool and the sunlight needed for ozone formation diminishes. Improved atmospheric mixing and changing weather conditions may also help disperse pollutants.

However, additional alerts may be issued if similar weather patterns persist. Residents should continue monitoring local forecasts and air quality advisories from state environmental agencies.

What is causing poor air quality in the affected locations?

The primary cause of poor air quality across these regions is elevated ground-level ozone formation.

Several atmospheric conditions are contributing to ozone accumulation:

Strong sunshine that accelerates ozone-producing chemical reactions
High pressure systems creating stagnant air conditions
Light winds that limit pollutant dispersion
Existing emissions from vehicles, industrial activities, and other pollution sources
Warm temperatures that enhance ozone formation

In South Carolina, officials specifically cited dominant high pressure, minimal cloud cover, low atmospheric moisture, light winds, and poor pollutant dispersion as key factors contributing to elevated ozone levels.

Home to millions of residents, five cities stood out as the most polluted major cities in the world for 2025 – find out which ones and why.

","The 2025 World Air Quality Report reveals the persistent global challenge posed by high concentrations of air pollution. Unhealthy air remains a daily reality for residents in some of the world’s most polluted urban centers. Tens of millions of people live in these cities and are exposed to elevated risks of respiratory and cardiovascular conditions over time (1). Many residents in these cities also face economic and social challenges that can compound the effects of long-term exposure to air pollution, challenges that are further compounded by exposure to industrial emissions, vehicular pollution, agricultural burning, and inadequate regulatory enforcement. Air pollution is an unequal burden for these residents, and for particularly vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions, like asthma. 5. Kinshasa, Democratic Republic of the Congo Kinshasa, the capital of the Democratic Republic of the Congo (DRC), ranked fifth among the world’s most polluted major cities in 2025. With an average annual PM2.5 concentration of 50.2 µg/m3, the city’s air quality remains in the hazardous air quality range as it has in prior years, continuing to pose serious health risks to city residents.Air quality in Kinshasa, DRC on April 20, 2026. Source: IQAir. Air pollution in Kinshasa can come from both indoor and outdoor sources. Indoor cooking with wood and charcoal, a common practice in many households, contributes significantly to airborne particulate matter. Forest fires, often linked to agricultural clearing and land management, release clouds of smoke into the atmosphere. Industrial activities and regional agricultural burning also contribute to poor air quality, compounded by limited regulatory oversight and enforcement. One of the biggest challenges to mitigating pollution is the lack of reliable air quality monitoring infrastructure in the DRC. While some monitoring stations exist, the DRC—like much of Africa—lacks the comprehensive networks needed to accurately track pollution levels and inform public health responses. 4. Kolkata, India Kolkata, India, was one of the world’s most polluted urban centers in 2025. With an average annual PM2.5 concentration of 51 µg/m3, it’s the city’s worst average since 2021’s annual average of 59 µg/m3.This change reflects regional trends, where rapid industrialization, vehicular emissions, and seasonal agricultural burning frequently create a haze that lingers over the city for much of the year. Air quality in Kolkata, India on April 21, 2026. Source: IQAir. Kolkata’s air pollution sources are deeply rooted in both local and regional activities. Vehicle emissions, industrial activity, construction dust, and unregulated waste burning add to the burden (2). During the winter months, crop residue burning in neighboring states and across the Indo-Gangetic Plain compounds the problem. 3. Dhaka, Bangladesh Dhaka, the capital of Bangladesh, returned as the world’s third most polluted major city in 2025, with an average annual PM2.5 concentration of 68 µg/m3. While Dhaka has experienced an improvement in average annual PM2.5 over 2024 and 2023 (measuring annual average concentrations of 78 and 80.2 µg/m3 respectively), its air quality remains far above safe levels. Persistent air quality challenges continue to affect residents’ health. Exposure to PM2.5, particulate matter measuring 2.5 microns in diameter or smaller, has been linked to respiratory diseases, heart conditions, stroke, and cancer (3). Air quality in Dhaka, Bangladesh on April 22, 2026. Source: IQAir. Informal brick kilns, which number in the thousands across Bangladesh, contributes an estimated 11% of the nation’s PM2.5 emissions and an additional 17% of its carbon dioxide (4). An estimated 6,000 premature deaths can be attributed to brick kiln air pollutants despite government efforts to shut down illegal operations and promote cleaner technologies like zigzag kilns. Industrial activity and diesel generators further impact air quality, while seasonal crop burning in rural areas adds to the city’s winter smog (5). Vehicle emissions, driven by a growing number of cars and buses on Dhaka’s streets, are also a major source of airborne pollutants. 2. Lahore, Pakistan Pakistan’s cultural and economic hub, Lahore, is again ranked the world’s second most polluted major city, with an average annual PM2.5 concentration of 88.9 µg/m3. While the PM2.5 concentration is an improvement over 2024’s average annual PM2.5 concentration of 102.1 µg/m3, the city’s high average contributed to Pakistan ranking as the most polluted country in 2025. The health impact from exposure to high concentrations of PM2.5 is significant; 70% of Pakistanis report smog-related health issues (6). Air quality in Lahore, Pakistan on April 20, 2026. Source: IQAir. Seasonal crop burning in Punjab Province blankets Lahore in thick smog. Vehicular emissions, exacerbated by an aging fleet and weak enforcement of emission standards, contribute significantly to the problem. Industrial activity, dust from construction and brick kilns, many of which operate without pollution controls, further degrade air quality (7)(8). 1. Delhi, India Delhi, India’s sprawling capital and one of the most populous cities in the world, has again topped the list of the most polluted major cities. With an average annual PM2.5 concentration of 99.6 µg/m3, its residents are exposed to to high levels of pollution on a near-daily basis. The city’s 2025 average is a modest improvement over both 2024 and 2023 whose average annual PM2.5 concentrations were 108.3 and 102.16 µg/m3 respectively. However, it’s still an average that is well into the hazardous air quality range. Air quality in Delhi, India on April 20, 2026. Source: IQAir. Delhi’s air pollution is caused by a combination of factors. Regional crop burning, particularly in the neighboring states of Punjab and Haryana, sends plumes of smoke into Delhi’s atmosphere every winter, creating a thick haze (9). Vehicular emissions, driven by millions of cars, trucks, and motorcycles—many of which operate on outdated technology—continue to serve as a major contributor (10). Coal-fired power plants, industrial emissions, and landfill fires further degrade air quality, while construction dust and unmanaged waste burning add to the burden. Same cities, too few changes Despite Kolkata, India replacing Karachi, Pakistan among the top five most polluted major cities in 2024, the other four major cities were all listed in 2024. Though they demonstrated some small air quality improvements over the prior year, Delhi, Lahore, and Dhaka all mirrored their top three positions in the 2024 listing. Their return as the three most polluted cities reflects the struggle residents and activists face in improving air quality outcomes. Because of the nearly year-round intensity of air pollution in all five cities, it is common to see them ranking among the most polluted major cities daily. Air quality in Delhi, India on April 20, 2026. Source: IQAir. Pathways to cleaner air Air pollution poses elevated health risks, but there are practical ways to reduce exposure and improve air quality in major cities. Here’s how air quality can be improved: What governments can do Strengthen air quality standards and enforce pollution control measures to create healthier urban environments. Invest in public transportation and promote renewable energy sources to reduce emissions. Implement stricter regulations on industrial and vehicular emissions. Expand air quality monitoring networks to inform policy decisions and public health strategies. What communities can do Support programs, such as Schools4Earth, to create healthier environments for vulnerable populations. Participate in community-driven data collection efforts to raise awareness and address pollution sources. What individuals can do Opt for sustainable transportation options like walking, biking, or public transit to lower emissions. Use energy-efficient appliances and indoor air purification systems to reduce personal exposure. Monitor air quality to help improve community air quality awareness. Access real-time air quality information to make informed decisions, especially on high-pollution days. Run an air purifier when air quality is poor. Wear a snug-fitting face mask outdoors on days when air pollution is severe. Conclusion Understanding and tackling urban air pollution starts with reliable, accessible data. Yet, in many parts of the world, comprehensive air quality monitoring remains limited or non-existent. Communities with access to real-time air quality information are better equipped to make informed decisions to protect their health, advocate for stronger policies and enforcement, and address pollution at its source. By expanding monitoring networks globally, individuals are empowered to improve public health and create cleaner, safer cities for everyone.","

Industrial activity and diesel generators further impact air quality, while seasonal crop burning in rural areas adds to the city’s winter smog (5). Vehicle emissions, driven by a growing number of cars and buses on Dhaka’s streets, are also a major source of airborne pollutants.

2. Lahore, Pakistan

Pakistan’s cultural and economic hub, Lahore, is again ranked the world’s second most polluted major city, with an average annual PM2.5 concentration of 88.9 µg/m3.

While the PM2.5 concentration is an improvement over 2024’s average annual PM2.5 concentration of 102.1 µg/m3, the city’s high average contributed to Pakistan ranking as the most polluted country in 2025. The health impact from exposure to high concentrations of PM2.5 is significant; 70% of Pakistanis report smog-related health issues (6).

Seasonal crop burning in Punjab Province blankets Lahore in thick smog. Vehicular emissions, exacerbated by an aging fleet and weak enforcement of emission standards, contribute significantly to the problem. Industrial activity, dust from construction and brick kilns, many of which operate without pollution controls, further degrade air quality (7)(8).

1. Delhi, India

Delhi, India’s sprawling capital and one of the most populous cities in the world, has again topped the list of the most polluted major cities. With an average annual PM2.5 concentration of 99.6 µg/m3, its residents are exposed to to high levels of pollution on a near-daily basis.

The city’s 2025 average is a modest improvement over both 2024 and 2023 whose average annual PM2.5 concentrations were 108.3 and 102.16 µg/m3 respectively. However, it’s still an average that is well into the hazardous air quality range.

Delhi’s air pollution is caused by a combination of factors. Regional crop burning, particularly in the neighboring states of Punjab and Haryana, sends plumes of smoke into Delhi’s atmosphere every winter, creating a thick haze (9). Vehicular emissions, driven by millions of cars, trucks, and motorcycles—many of which operate on outdated technology—continue to serve as a major contributor (10). Coal-fired power plants, industrial emissions, and landfill fires further degrade air quality, while construction dust and unmanaged waste burning add to the burden.

Same cities, too few changes

Despite Kolkata, India replacing Karachi, Pakistan among the top five most polluted major cities in 2024, the other four major cities were all listed in 2024. Though they demonstrated some small air quality improvements over the prior year, Delhi, Lahore, and Dhaka all mirrored their top three positions in the 2024 listing. Their return as the three most polluted cities reflects the struggle residents and activists face in improving air quality outcomes.

Because of the nearly year-round intensity of air pollution in all five cities, it is common to see them ranking among the most polluted major cities daily.

\nPathways to cleaner air

Air pollution poses elevated health risks, but there are practical ways to reduce exposure and improve air quality in major cities. Here’s how air quality can be improved:

What governments can do

Strengthen air quality standards and enforce pollution control measures to create healthier urban environments.
Invest in public transportation and promote renewable energy sources to reduce emissions.
Implement stricter regulations on industrial and vehicular emissions.
Expand air quality monitoring networks to inform policy decisions and public health strategies.

What communities can do

Support programs, such as Schools4Earth, to create healthier environments for vulnerable populations.
Participate in community-driven data collection efforts to raise awareness and address pollution sources.

What individuals can do

Opt for sustainable transportation options like walking, biking, or public transit to lower emissions.
Use energy-efficient appliances and indoor air purification systems to reduce personal exposure.
\nMonitor air quality to help improve community air quality awareness.
\nAccess real-time air quality information to make informed decisions, especially on high-pollution days.
Run an air purifier when air quality is poor.
\nWear a snug-fitting face mask outdoors on days when air pollution is severe.

Conclusion

Understanding and tackling urban air pollution starts with reliable, accessible data. Yet, in many parts of the world, comprehensive air quality monitoring remains limited or non-existent.

Communities with access to real-time air quality information are better equipped to make informed decisions to protect their health, advocate for stronger policies and enforcement, and address pollution at its source. By expanding monitoring networks globally, individuals are empowered to improve public health and create cleaner, safer cities for everyone.
