Widespread flooding continues across multiple regions of Southeast Australia after a slow-moving low-pressure system brought heavy rainfall.

","content","What is the location of the flooding? As of March 3, 2026, the Southeast Australia Flooding is impacting large parts of Victoria, South Australia, New South Wales and Queensland. The flooding is fueled by a record-breaking inland rainfall event, with some towns receiving a full year’s rain in just one week. The Bureau of Meteorology described the event as ‘once in a generation’ and compared the sudden shift from extreme heat (up to 50°C weeks earlier) to intense rainfall as ‘weather whiplash’ (1). Key rivers and catchments involved include the Lower Murrumbidgee River, Darling River, Cooper Creek, Warburton River, and multiple Victorian catchments such as the Avoca, Loddon, Campaspe and Wimmera systems (2). Which cities or areas are affected by the flooding? The following areas have been directly or indirectly impacted by flooding: South Australia: Adelaide, Eurelia (where a fatal flash-flooding incident occurred), Yunta (126.8mm in a single day), Ceduna (75mm), Marree (136mm), Innamincka New South Wales: Balranald, Broken Hill, Deniliquin, Hay, Menindee, Wentworth Victoria: Bendigo, Cohuna, Horsham (126mm in 48 hours), Mildura (nearly 150mm in one week) Queensland: Birdsville, Camoola Park, Jundah, Longreach, Retreat, Stonehenge, Windorah Meteorologists describe the system as a ‘once-in-a-generation’ rainfall event, delivering the heaviest inland rain since 2011. Several desert towns experienced rainfall usually only seen in tropical cities like Darwin or Cairns (3). What is the current containment status of the flooding? As of March 3, 2026, the rainfall has intensified, with severe weather warnings expanded across SA, NSW, and Victoria (4). Flash flooding has become more widespread due to saturated soil and 40–100mm six-hour rainfall bursts. Multiple regions are now experiencing their wettest days on record, pushing several river systems toward major flood levels (5). Victoria continues to experience minor to moderate flooding, with rainfall maintaining elevated river levels across central, northwest and southwest catchments (6). Far western New South Wales is facing localized flooding, with wet catchments responding rapidly to new rainfall and some communities at risk of isolation (7). South Australia is seeing easing conditions around Innamincka, but renewed river level increases are occurring along the Warburton River and across eastern districts where heavy rainfall continues (8). Queensland is experiencing moderate to major flooding along the Thomson River, Barcoo River and Cooper Creek, with peak flows moving downstream through affected areas. Authorities continue to refine flood forecasts and closely monitor river gauges across all impacted regions. Are there any evacuation orders or alerts in place? Although mandatory evacuations remain limited, emergency services are seeing a sharp increase in flood-related incidents. Victoria has recorded 392 SES requests, mostly for flooding, fallen trees and property damage. 176 of these callouts occurred in the past 24 hours. Several vehicles have been trapped in rising water, including a truck stranded on the Barrier Highway. South Australia and New South Wales warn that flash flooding may become life-threatening, especially in outback areas where water can rise quickly (9). SA continues to issue flood watches and severe weather warnings for heavy rain, flash flooding and dangerous road conditions. Communities in far-western NSW are under advisories due to the risk of isolation and limited road access. Queensland authorities urge residents near Longreach, Jundah, Stonehenge and Windorah to avoid flooded roads as river levels continue to rise (10). Victoria also maintains riverine flood watches across central, northwest and southwest regions, advising the public to stay informed and avoid floodwaters (11). Across all affected states, residents are urged to stay alert, avoid entering floodwater and follow official emergency instructions. 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.","contentHtml","

Abandoned and orphan oil and gas wells can leak methane and co-pollutants. Learn what’s hard to detect, what to watch for, and how to reduce exposure.

","Across the oil and gas producing regions around the world, millions of wells have been drilled, pumped, and eventually shut down. Some were sealed properly. Others were left idle, forgotten, or tied up in bankruptcies. Many sit quietly in farm fields, forests, suburbs, and even near growing towns—out of sight and largely out of mind. Even decades after production ends, abandoned and orphan oil and gas wells can release methane and other co-pollutants into surrounding air and soil. These releases can be localized and episodic—quiet for long stretches, then noticeable during shifts in pressure, weather, or ground conditions. They rarely show up on standard air dashboards. And because monitoring is uneven, the impacts can extend into nearby homes and communities—sometimes in places where few people realize a well is even present. What are abandoned, orphan, and “legacy” wells? Ideally, when a well reaches the end of its productive life, it is plugged and abandoned—sealed with cement and other barriers to prevent oil, gas, or fluids from migrating to the surface. Wells are described using a few common terms that reflect whether they are producing, sealed, or still someone’s responsibility: Inactive or idle wells: Not currently producing but not permanently sealed. Abandoned wells: No longer in use; may or may not have been properly plugged. Orphan wells: Abandoned wells with no financially viable owner responsible for cleanup. Legacy wells: A broad term for older wells drilled under past standards. Why does that matter? Plugging standards have changed significantly over time. Older wells may lack the multiple cement barriers and monitoring protocols required today. And as decades pass, steel casings can corrode and cement can degrade, increasing the potential for leaks. Where are these wells—and who lives near them? Abandoned and orphan wells aren’t limited to one kind of landscape. They can be found in rural farm fields and forests, along historic production corridors, and in some places within or near growing towns. Globally, estimates vary because countries track wells differently, and many older wells were drilled before modern recordkeeping. A 2022 National Science Review study estimated approximately 4.5 million abandoned oil and gas wells across 127 countries, drawing on national and regional datasets, with detailed well-level data available for around 420,000 wells. The authors estimated nearly 0.4 million tons of methane emitted in 2022, with emissions concentrated in a small set of countries (including the United States, as well as Canada, Romania, the UK, and Brazil) — and noted that uncertainty is highest where registries are incomplete or outdated (1) (2) Other estimates are much higher (some reaching up to 29 million wells), reflecting broader definitions and larger historical data gaps (3) (4). Where wells are located—and how close they are to homes, schools, and workplaces—often determines whether abandoned wells feel like a distant climate problem or a local exposure concern. In the United States, documented orphan wells are especially concentrated in parts of Appalachia and the industrial Midwest, with additional dense clusters across the Southern Plains and into the western Gulf Coast. California also has thousands of documented wells, including in and around parts of the Los Angeles basin. The pattern is easiest to see where records are strongest: documented wells tend to cluster along older production corridors, with smaller pockets appearing as towns expanded around historic sites. A 2022 analysis identified 123,318 documented orphan wells in the United States. Four states account for about 56% of documented orphan wells: Ohio: 17% Pennsylvania: 15% Oklahoma: 13% Kentucky: 12% The remaining wells are distributed across many other states, from New York to Wyoming (5). Documented wells are only part of the picture. Researchers note that undocumented wells—often older and harder to locate—may exist in the hundreds of thousands to several million, meaning some communities may have nearby wells that aren’t yet mapped in public databases (6). Proximity also matters. One national mapping effort estimated that millions of people in the U.S. live within about a mile of a documented orphan well, making this an “invisible infrastructure” issue that intersects with housing, land use, and public health—not just energy history (7).The U.S. is a major hotspot — but abandoned wells are a global legacy issue with uneven tracking. What can these wells release—and why is it hard to detect? The primary gas associated with abandoned wells is methane. Methane is colorless and odorless. It is not toxic at typical environmental concentrations, but it is a potent greenhouse gas. Importantly, for nearby communities, methane releases can occur alongside other substances. Co-pollutants include: Volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene, and xylene. Some VOCs can irritate the eyes, nose, and throat and contribute to headaches or dizziness at higher exposures; benzene is a well-established carcinogen. Hydrogen sulfide (H₂S): often associated with a “rotten egg” odor at low levels; it can irritate eyes and airways and cause symptoms like headaches or nausea, and high concentrations can be dangerous and require immediate safety response. Nitrogen oxides and other ozone precursors: in sunlight they can contribute to ground-level ozone, which is linked to respiratory irritation and worsening asthma symptoms. One reason well-related emissions are often described as “invisible” is that they typically do not appear in the daily Air Quality Index (AQI). The AQI primarily reflects fine particulate matter (PM2.5), ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Methane is not included in the index, and routine VOC monitoring is limited in many rural and semi-rural areas where legacy wells are common. That means a “good AQI day” doesn’t automatically rule out localized gas or VOC issues near a site—especially if the concern is episodic leakage rather than regional smog. Monitoring tools are improving. Optical gas imaging (OGI) cameras can visualize some plumes, and aircraft or satellite platforms can flag methane emissions over broader areas. Field teams can also sample methane and VOCs near specific sites. But these methods aren’t deployed consistently—especially in rural areas—so leaks can persist without being quickly confirmed or reflected in public-facing dashboards. Why might leaks or blowouts occur? Think of a well as a deep borehole that once carried fluids and gas to the surface. When it’s properly plugged, it’s sealed like a capped pipe—designed to stay closed for the long term. But as wells age—and as conditions underground change—small failures can create a route for gas or fluids to move where they shouldn’t. Researchers and regulators point to several possible contributors: Aging materials: Steel casing can corrode and the cement designed to seal the well can crack or degrade over time. Even small gaps can allow gas to migrate upward. Changes in underground pressure: Some studies suggest that wastewater injection associated with oil and gas operations can raise subsurface pressures in certain areas. Higher pressure may push fluids and gas toward weak points—especially in older wells. Regulators emphasize that impacts vary by geology, injection practices, and local conditions. Natural geology: Fractures, faults, and porous rock layers can provide pathways for gas migration, particularly when they intersect older wells. Scientists and regulators also caution that proving direct cause-and-effect requires site-specific investigation, and that conditions differ widely from one basin to another. Why cleanup is complex—and expensive Plugging a well properly is labor-intensive and costly. Depending on depth and condition, costs can range from $20,000 to over $150,000 per well, with complex sites costing more. In 2021, the Bipartisan Infrastructure Law allocated $4.7 billion for orphan well plugging across the United States. States have since launched expanded programs to inventory and seal wells. Yet the number of wells far exceeds current funding levels (8). Bonding requirements—financial assurances that operators post to cover cleanup—have been widely criticized as insufficient in many states. When companies go bankrupt, liabilities can shift to taxpayers. Cleanup is rarely a single step—it’s a multi-stage process that starts with finding the well and ends with verifying that it stays sealed over time. What makes this challenging is that the work is part engineering, part detection, and part verification—especially for older or undocumented sites. In practice, cleanup often involves: Locating and mapping wells (including undocumented sites). Testing for emissions and assessing site conditions. Installing multiple cement plugs and a surface cap to prevent migration. Monitoring after closure to confirm long-term integrity. Each step takes time, specialized crews, and coordination with landowners and regulators—so even when funding expands, the pace of work can be limited by capacity. That’s why progress is real, but the backlog remains large—and why practical day-to-day protection matters while cleanup capacity scales. Advocate for cleanup The only durable solution to emissions from abandoned and orphan wells is proper plugging and site remediation—so the well no longer provides a pathway for gas or fluids to migrate. Cleanup is technical, but the logic is simple: Close the pathway (seal the well) Remove the infrastructure (surface equipment and hazards) Restore the surface (reclaim the land) For communities, the most effective advocacy usually centers on prioritization and accountability: getting the highest-risk wells addressed first, ensuring responsible parties fund cleanup where possible, and making sure closures are verified (9) (10). Public funding has accelerated progress, but the backlog remains large. Under the U.S. Department of the Interior’s Orphaned Wells Program (authorized through the Infrastructure Investment and Jobs Act), states can apply for multiple grant types through 2030—and as of the end of federal fiscal year 2025, more than $1 billion in Formula funds and $1.3 billion in Performance grant funds remained available for states to apply for. These programs can support not only plugging, but also remediation, reclamation, and—in some cases—measurement and tracking of methane and other emissions (11). The remaining challenge is scale and prevention. Even as historic orphan wells are addressed, policies still matter for reducing future liabilities—especially around financial assurance (bonding), idle well management timelines, and restrictions on transferring aging wells to undercapitalized operators.The most effective advocacy tends to focus on a few concrete asks: Accelerate plugging and remediation timelines for idle and orphan wells in high-exposure areas. Strengthen bonding requirements so cleanup is funded by responsible operators—not taxpayers. Improve mapping and transparency so communities and landowners know where wells and related infrastructure are located. Support monitoring where it changes outcomes for verification of emissions, prioritization, and post-closure integrity checks. In states like Illinois, investigative reporting and legal analysis have highlighted how weak bonding, limited data, and slow enforcement can shift cleanup costs toward the public—an example of why strong cleanup policy matters as much as the technical work itself (12). Ultimately, advocating for cleanup is about moving from awareness to accountability. Monitoring helps identify problems, and household strategies can reduce exposure in the meantime—but plugging and restoration is what ends emissions at the source. The more consistently communities push for funded, enforceable cleanup, the faster “invisible” pollution becomes measurable, manageable, and preventable. Conclusion Abandoned and orphan oil and gas wells represent a form of pollution that is often unseen and under-tracked. Methane and co-pollutants may not appear on standard air dashboards, yet they can influence local air quality and climate over time. Progress is real: awareness is rising, detection tools are improving, and cleanup programs are expanding. The near-term goal is to find and prioritize the highest-risk wells, while helping households and communities reduce exposure where monitoring is limited. The long-term goal is straightforward: plug, verify, and restore—so “invisible” pollution becomes measurable, manageable, and preventable.","

Record rainfall has unleashed deadly floods and landslides across southeastern Brazil, killing dozens and displacing communities. Learn about affected areas, response efforts, and ongoing alerts.

","What is the location of the flooding? As of February 25, 2026, persistent torrential rainfall has impacted southeastern Brazil, particularly the states of Minas Gerais, Espírito Santo, and Rio de Janeiro. Intense rainfall over several days caused rivers to overflow and hillsides to collapse, triggering widespread flooding and deadly landslides. The worst impacts are concentrated in mountainous and riverside areas where rain totals shattered previous records, overwhelming infrastructure and drainage systems (1). Which cities or areas are affected by the flooding? Flooding and landslides have devastated multiple cities and towns in the region: Minas Gerais: Particularly in mountainous municipalities near river basins. Espírito Santo: Coastal and inland communities submerged by swollen rivers. Rio de Janeiro: Mountainous regions and hillside neighborhoods hit by landslides. In these areas, saturated slopes and fast-rising floodwaters have destroyed homes, blocked roads, and isolated communities. Emergency crews are navigating impassable highways and debris-strewn neighborhoods as rescue operations continue. What is the current containment status of the flooding? Rescue and response efforts are ongoing as floodwaters remain elevated in many river basins. Civil defense authorities have plucked survivors from rooftops and washed-out roads, while helicopters search for missing residents amid flooded valleys (2). Water levels in several rivers are still high, slowing recovery and containment efforts. Officials warn that additional rainfall may compound existing flood damage and hamper relief operations (3). Are there any evacuation orders or alerts in place? Authorities have issued widespread flood and landslide warnings across southeastern Brazil as rain continues to fall intermittently. Evacuation orders have been enforced in the most dangerous flood zones, and shelters are operating to house displaced families (4). Residents are urged to stay away from swollen rivers, avoid unstable slopes, and follow guidance from Brazil’s civil defense agencies as updated advisories are issued. 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.

What is the location of the flooding?

As of February 25, 2026, persistent torrential rainfall has impacted southeastern Brazil, particularly the states of Minas Gerais, Espírito Santo, and Rio de Janeiro. Intense rainfall over several days caused rivers to overflow and hillsides to collapse, triggering widespread flooding and deadly landslides.

The worst impacts are concentrated in mountainous and riverside areas where rain totals shattered previous records, overwhelming infrastructure and drainage systems (1).

Which cities or areas are affected by the flooding?

Flooding and landslides have devastated multiple cities and towns in the region:

\nMinas Gerais: Particularly in mountainous municipalities near river basins.
\nEspírito Santo: Coastal and inland communities submerged by swollen rivers.
\nRio de Janeiro: Mountainous regions and hillside neighborhoods hit by landslides.

In these areas, saturated slopes and fast-rising floodwaters have destroyed homes, blocked roads, and isolated communities. Emergency crews are navigating impassable highways and debris-strewn neighborhoods as rescue operations continue.

What is the current containment status of the flooding?

Rescue and response efforts are ongoing as floodwaters remain elevated in many river basins. Civil defense authorities have plucked survivors from rooftops and washed-out roads, while helicopters search for missing residents amid flooded valleys (2).

Water levels in several rivers are still high, slowing recovery and containment efforts. Officials warn that additional rainfall may compound existing flood damage and hamper relief operations (3).

Are there any evacuation orders or alerts in place?

Authorities have issued widespread flood and landslide warnings across southeastern Brazil as rain continues to fall intermittently. Evacuation orders have been enforced in the most dangerous flood zones, and shelters are operating to house displaced families (4).

Residents are urged to stay away from swollen rivers, avoid unstable slopes, and follow guidance from Brazil’s civil defense agencies as updated advisories are issued.

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.
\nRun 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.

New research highlights how air pollution can quietly disrupt sleep — and treatments that can help restore your sleep.

","We all know air pollution harms the heart, lungs, and brain — but new evidence shows it can also steal our sleep.A comprehensive study out of Johns Hopkins University School of Nursing analyzed data from more than 1.2 million adults across six countries. The results are striking: people exposed to higher levels of air pollution, including fine particulate matter (PM2.5), nitrogen dioxide (NO₂), and carbon dioxide (CO₂), consistently reported shorter or poorer-quality sleep (1).Sleep is foundational to immune function, cognitive performance, and emotional regulation — making air quality a powerful factor in how well we rest.What makes this connection especially important is that sleep isn’t just a nightly routine — it’s a biological reset that pollution can quietly disrupt without us noticing.From early childhood through older adulthood, disrupted sleep compounds health risks — making air quality a quiet but consistent influence on sleep health. The hidden link between air pollution and sleep Sleep is shaped by far more than light, noise, or bedtime habits. The air we breathe—hour after hour, night after night—plays a subtle but powerful role in how deeply we sleep, how often we wake, and how well the body recovers overnight. According to the study, even modest pollution increases were linked with restless nights, insomnia, and shorter sleep duration — more impactful effects than scientists expected. “Air quality – both outdoors and inside the home – is an underrecognized contributor to sleep problems,” said Dr. Junxin Li, lead researcher for the study. “Cleaner air not only safeguards lungs and hearts, it also helps people sleep, supporting cognition, mood, and overall resilience.” These findings point to a broader pattern: air pollution doesn’t just affect sleep in extreme conditions, but subtly influences sleep quality across populations, environments, and everyday exposure levels. Cleaner air…helps people sleep, supporting cognition, mood, and overall resilience.”—Dr. Junxin Li, Johns Hopkins University What the research show The review combined findings from 25 high-quality studies conducted since 2015, covering adults over 45 years old in China, India, the U.S., Germany, and other nations. It was found that cutting average PM2.5 concentrations in half—from the levels typically found on busy city streets down to the World Health Organization (WHO) guideline—could reduce the likelihood of poor sleep by about 10 percent among middle-aged and older adults. In other words, cleaner air could help millions of people gain roughly an extra hour of rest each night. That insight helps explain why sleep disruption shows up not only in polluted cities, but also in everyday indoor spaces where people spend much of their lives. Indoor air matters, too While outdoor air pollution often gets the most attention, indoor air quality plays a critical role in sleep health—especially because people spend nearly a third of their lives asleep indoors. For many adults, nighttime exposure inside the home may represent their longest and most consistent contact with air pollution. Dr. Li’s team found that indoor pollution can be just as harmful — especially for older adults, who often spend most of their time indoors. Only six high-quality studies examined indoor sources, but their conclusions were clear: households using solid fuels such as coal or wood for cooking or heating reported far worse sleep outcomes than those using clean energy. And homes that used ventilation fans or opened windows during cooking saw notable improvements in sleep quality — evidence that even small steps to improve indoor air can matter. Sleep quality isn’t shaped only by what happens during the day, but by the air we’re exposed to night after night—making it important to understand how air pollution disrupts sleep in the first place. How air pollution disrupts sleep quality Air pollution can interfere with sleep quality through inflammation, nervous-system stimulation, and reduced oxygen exchange during the night. Prolonged exposure to even low-level pollutants can interfere with the body’s natural recovery processes.Unlike daytime exposure — which is intermittent — sleep creates a long, uninterrupted window where the body is continuously affected by the air it breathes. That makes nighttime air quality especially influential, even when pollution levels are relatively low.Scientists are still uncovering the mechanisms linking pollution to sleep problems, but several pathways are already well-understood: Inflammation and oxidative stress: Fine particles penetrate deep into the lungs and bloodstream, triggering systemic inflammation that can disturb normal sleep cycles. Nervous-system stimulation: Nitrogen dioxide and other gases can activate stress responses that increase heart rate and restlessness. Reduced oxygen exchange: Elevated CO₂ levels in bedrooms can lower oxygen availability, fragmenting deep sleep and REM phases. Noise and thermal effects: Polluted urban environments often coincide with traffic noise and higher nighttime temperatures — both known sleep disruptors. The outcome? More tossing, turning, and waking — and fewer restorative hours of rest. How clean air supports deeper, more restorative sleep When the air you breathe is free of pollutants, your body can maintain balanced oxygen and carbon-dioxide levels. Your heart rate stays steady, airways remain open, and inflammation decreases. That supports slow-wave (deep) sleep, the stage critical for physical repair and immune recovery. Nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. In studies of adults with asthma or cardiovascular disease, nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. Over time, better sleep quality is linked to lower cardiovascular risk, stronger immune response, improved memory, and better mental health — amplifying the health benefits of cleaner air beyond the bedroom. Indoor air quality while you sleep During sleep, we spend several uninterrupted hours breathing the air in a single enclosed space. Unlike daytime hours—when doors open, windows are used, and air is constantly exchanged—bedrooms often become more sealed at night, allowing pollutants to accumulate. Research shows that indoor air pollution can exceed outdoor levels by two to five times, especially overnight when ventilation is reduced. For people living near busy roads, dense urban corridors, or industrial areas, nighttime exposure may remain elevated—even when outdoor air quality appears good during the day. The encouraging news is that many of the most common bedroom pollutants are well understood—and highly controllable once identified. Understanding where these pollutants come from makes it easier to reduce exposure and create a sleep environment that supports the body’s natural overnight recovery. Common bedroom pollutants include: PM2.5 and ultrafine particles — from traffic exhaust, cooking, and candles.Impact: Can increase inflammation and interfere with deep, restorative sleep. Nitrogen dioxide (NO₂) — from gas stoves and heaters.Impact: May trigger airway irritation, wheezing, and nighttime restlessness. Volatile organic compounds (VOCs) — from cleaning products, paints, and new furniture.Impact: Can contribute to headaches, dizziness, and difficulty falling asleep. Carbon dioxide (CO₂) — from human exhalation in sealed rooms.Impact: Higher levels are associated with drowsiness and fragmented sleep. With the right combination of ventilation, monitoring, and filtration, these exposures can be significantly reduced—helping create a calmer, more supportive environment for sleep. Clean air solutions for better rest Improving sleep through cleaner air isn’t about perfection — it’s about reducing exposure where it matters most, during the hours your body is working hardest to recover. Sleep is a prolonged, uninterrupted activity, so small improvements in air quality can have an outsized impact overnight. Protecting sleep quality requires a layered approach to improving indoor air quality: Monitor indoor and outdoor air quality: Tracking conditions with an air quality monitor helps identify patterns—such as elevated PM2.5 or CO₂ levels at night—and informs when ventilation or filtration is most beneficial. Real-time data makes it easier to respond proactively rather than guessing. Downloading an air quality app can also provide outdoor air quality in the palm of your hand. Ventilate strategically: When outdoor air quality is good, opening windows or using extractor fans during cooking and cleaning helps prevent pollutants from building up indoors. Even brief ventilation before bedtime can lower overnight exposure. Use high-performance filtration where you sleep: Because the smallest particles are most likely to penetrate deep into the lungs and disrupt sleep, filtration that captures ultrafine particles is especially important in bedrooms. Air purifiers with HyperHEPA filtration are designed to remove particles far smaller than the limits of standard HEPA. Together, these steps help create an indoor environment that works with the body’s natural sleep processes, making cleaner air an enabler of deeper, more restorative rest. Studies suggest that improvements in bedroom air quality can influence sleep quality within days or weeks, not just over months or years. Conclusion Sleep is one of the body’s most powerful recovery tools — and the air you breathe plays a meaningful role in how well it works. By reducing exposure to particulate pollution indoors and out, you can support healthier sleep, protect your lungs, heart, and brain, and give your body the restorative rest it needs—especially over the long term.","

During sleep, we spend several uninterrupted hours breathing the air in a single enclosed space. Unlike daytime hours—when doors open, windows are used, and air is constantly exchanged—bedrooms often become more sealed at night, allowing pollutants to accumulate.

Research shows that indoor air pollution can exceed outdoor levels by two to five times, especially overnight when ventilation is reduced. For people living near busy roads, dense urban corridors, or industrial areas, nighttime exposure may remain elevated—even when outdoor air quality appears good during the day.

The encouraging news is that many of the most common bedroom pollutants are well understood—and highly controllable once identified. Understanding where these pollutants come from makes it easier to reduce exposure and create a sleep environment that supports the body’s natural overnight recovery.

Common bedroom pollutants include:

\nPM2.5 and ultrafine particles — from traffic exhaust, cooking, and candles.
Impact: Can increase inflammation and interfere with deep, restorative sleep.
\nNitrogen dioxide (NO₂) — from gas stoves and heaters.
Impact: May trigger airway irritation, wheezing, and nighttime restlessness.
\nVolatile organic compounds (VOCs) — from cleaning products, paints, and new furniture.
Impact: Can contribute to headaches, dizziness, and difficulty falling asleep.
\nCarbon dioxide (CO₂) — from human exhalation in sealed rooms.
Impact: Higher levels are associated with drowsiness and fragmented sleep.

With the right combination of ventilation, monitoring, and filtration, these exposures can be significantly reduced—helping create a calmer, more supportive environment for sleep.

Clean air solutions for better rest

Improving sleep through cleaner air isn’t about perfection — it’s about reducing exposure where it matters most, during the hours your body is working hardest to recover. Sleep is a prolonged, uninterrupted activity, so small improvements in air quality can have an outsized impact overnight.

Protecting sleep quality requires a layered approach to improving indoor air quality:

\nMonitor indoor and outdoor air quality: Tracking conditions with an air quality monitor helps identify patterns—such as elevated PM2.5 or CO₂ levels at night—and informs when ventilation or filtration is most beneficial. Real-time data makes it easier to respond proactively rather than guessing. Downloading an air quality app can also provide outdoor air quality in the palm of your hand.
\nVentilate strategically: When outdoor air quality is good, opening windows or using extractor fans during cooking and cleaning helps prevent pollutants from building up indoors. Even brief ventilation before bedtime can lower overnight exposure.
\nUse high-performance filtration where you sleep: Because the smallest particles are most likely to penetrate deep into the lungs and disrupt sleep, filtration that captures ultrafine particles is especially important in bedrooms. Air purifiers with HyperHEPA filtration are designed to remove particles far smaller than the limits of standard HEPA.

Together, these steps help create an indoor environment that works with the body’s natural sleep processes, making cleaner air an enabler of deeper, more restorative rest. Studies suggest that improvements in bedroom air quality can influence sleep quality within days or weeks, not just over months or years.

Conclusion

Sleep is one of the body’s most powerful recovery tools — and the air you breathe plays a meaningful role in how well it works.

By reducing exposure to particulate pollution indoors and out, you can support healthier sleep, protect your lungs, heart, and brain, and give your body the restorative rest it needs—especially over the long term.

","Is the air quality good in Incheon? On February 20, 2026, at 8:00 AM PT, air quality in Incheon, South Korea is in the unhealth for sensitive groups range. Most of South Korea is experiencing air quality in the unhealthy for sensitive groups to unhealthy range due to a combination of factors. Poor air quality is partially a result of dust from outside Korea, in addition to stagnant winter weather, industrial pollution and vehicle emissions, nighttime biomass burning, and possibly sea salt (1)(2)(3). Air quality is dynamic and, like the weather, can change frequently. Incheon ranked 10th among the most polluted major cities in the world on Friday. Seoul was the 11th most polluted major city and Busan was the 23rd. Click here for a real-time air quality map of Incheon. While the air quality today is poor, it should be noted that the average PM2.5 concentration in 2024 for Incheon was 19.1 µg/m³, corresponding to an AQI of 65 (“moderate”), and was 3.8 times the WHO annual guideline of 5 µg/m³.

Air quality map of South Korea on Feb 20, 2026. Source: IQAir. What is causing poor air quality in Incheon? Research from both regional and international sources confirms that transboundary pollution from China significantly affects fine dust concentrations in South Korea. Studies suggest that approximately 19 percent of Korea’s particulate matter originates from outside its borders, with certain months seeing up to 55 percent of ultrafine dust linked to emissions from China (3). Westerly winds carry pollutants from industrial zones in eastern China, while seasonal stagnant air conditions trap these particles over the Korean Peninsula. Meanwhile, local sources—such as industrial operations and vehicle emissions in Incheon—exacerbate pollution levels in the region.

Is the air quality good in Incheon?

On February 20, 2026, at 8:00 AM PT, air quality in Incheon, South Korea is in the unhealth for sensitive groups range. Most of South Korea is experiencing air quality in the unhealthy for sensitive groups to unhealthy range due to a combination of factors.

Poor air quality is partially a result of dust from outside Korea, in addition to stagnant winter weather, industrial pollution and vehicle emissions, nighttime biomass burning, and possibly sea salt (1)(2)(3).

Air quality is dynamic and, like the weather, can change frequently. Incheon ranked 10th among the most polluted major cities in the world on Friday. Seoul was the 11th most polluted major city and Busan was the 23rd.

What is causing poor air quality in Incheon?

Research from both regional and international sources confirms that transboundary pollution from China significantly affects fine dust concentrations in South Korea. Studies suggest that approximately 19 percent of Korea’s particulate matter originates from outside its borders, with certain months seeing up to 55 percent of ultrafine dust linked to emissions from China (3).

Westerly winds carry pollutants from industrial zones in eastern China, while seasonal stagnant air conditions trap these particles over the Korean Peninsula. Meanwhile, local sources—such as industrial operations and vehicle emissions in Incheon—exacerbate pollution levels in the region.

As winds are also being driven north from the sea, sea salt can contribute to the mix of industrial pollutants.

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

","When choosing an air purifier, one of the first numbers people encounter is CADR—but it is also one of the most misunderstood. CADR, or Clean Air Delivery Rate, measures how quickly an air purifier can clean the air in a space. It is often used to compare different models, but on its own it does not reflect how an air purifier performs in real-world conditions over time. CADR focuses on short-term performance—how quickly clean air is delivered under specific conditions—rather than how long that performance can be maintained. Understanding how CADR works—and how it differs from other metrics like CCM—can make it easier to choose a system that matches both the size of a space and how performance will hold over time. What CADR actually measures CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space. In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time. CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage. CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline. The limitation of CADR: Speed vs long-term performance While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time. As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture. Many air purifiers perform well when new but lose effectiveness as filters become saturated. As a result, CADR alone gives an incomplete—or even misleading—picture of how an air purifier will perform outside of controlled test conditions. CADR vs CCM: Speed vs endurance While CADR measures speed, CCM focuses on endurance. It tracks how much pollution an air purifier can remove over time before its performance begins to decline. CCM ratings are grouped into standardized tiers for particulate matter (P) and formaldehyde (F), which indicate how much pollution an air purifier can handle before its performance begins to decline. Higher tiers represent greater long-term filtration capacity and more stable performance over time.

For example, a system rated at P4 can remove significantly more particulate matter before performance declines than one rated at P1. Compared to CADR, CCM reflects long-term filtration performance rather than short-term speed. In practice, CADR reflects how quickly an air purifier performs under initial test conditions, while CCM provides clearer insight into how that performance holds up over time. How to evaluate air purifier performance in real-world use Understanding how an air purifier is tested can help clarify how it will perform in real-world use. If a system is too small for a space, or if performance declines over time, airborne particles may remain present. Systems with higher CCM levels are more likely to maintain consistent performance over time, which can be especially relevant for sensitive or allergy-prone groups.

For example, systems using high-efficiency filtration, such as IQAir systems using HyperHEPA filtration, are designed to capture ultrafine particles efficiently while maintaining long-term performance. Frequently Asked Questions What is the difference between CADR and CCM? CADR measures initial short-term performance quality, calculating the rate or speed of which airborne particulate matter is cleaned and recycled.

Rather than focusing on a single location or data contributor, the program is designed to connect many, linking classrooms through a common learning framework and shared data.

Learning that starts with context

Developed with educators and subject experts, the Air We Breathe program is designed for students ages 7 to 14. It’s free for schools worldwide and built to fit into existing curricula.

The program moves between history, science, and present-day air quality. Lessons explore how air pollution has developed over time, from early human activity through the industrial period and into the present. They also look at how air quality connects to health, climate, and the way communities function, with an opportunity to think about local innovation and action.

That foundation becomes more meaningful once students begin working with real-world data.

Working with data from their own environment

Each school uses an IQAir AirVisual Outdoor monitor to measure local air quality. Those readings feed into the IQAir platform, where they can be accessed through the AirVisual app, desktop dashboard, and global air quality map.

Students aren’t just checking the numbers. They follow how readings change over time, compare patterns across different days, and begin asking why those changes happen.

Owen described it simply: students are “playing with the data, looking at the data, comparing their data with others.”

For EarthMuseum Learn, the appeal of the system was not just the data itself, but how easily it could be used across different classrooms globally. Once tested, Owen said, “it was pretty straightforward to set up,” and “very communicative in terms of the data.”

The platform also places those readings alongside a much wider network of stations, contributed by governments, organizations, and individuals around the world. That context makes it easier to see how local conditions fit into a broader picture. In practice, each school becomes one point within a much larger network of observations.

Comparing across locations

Students have the ability to look at their own data alongside readings from partner schools in other regions, from nearby cities to entirely different countries.

Seeing those differences tends to raise immediate questions. Owen said students begin to ask, “Why are levels higher in one place than another? What local factors might be involved? How do infrastructure, geography, or policy play a role?” For the program, that exchange is central. It’s about “that ability to compare and contrast, to talk, to discuss, and to understand what’s happening in different places.”

What starts as a local exercise becomes something shared, and something that allows students to see their community in a global context.

Understanding how air quality data is created

Alongside real-time monitoring, students take manual readings at set intervals, recording and sharing those observations through EarthMuseum Learn’s developing collaborative platform.

For many, this is their first experience working with environmental data in a structured way. It makes them more comfortable reading the numbers and talking about what those numbers mean.

Because those observations are shared across schools, they don’t stay local—they contribute to a broader, collective view.

From observation to response

Students are encouraged to consider what their observations mean in practical terms—for themselves, for their school, and for the wider community. Sometimes that may lead to small changes in the school environment. In other cases, it can develop into campaigns or presentations shared with local decision-makers. Owen said, “Students see that data isn’t just something on a screen, or something collected in a vacuum. They see how it’s interpreted—and how it can help make an impact in their world.”

That thinking is shaped not only by their own data, but by what they see happening in other schools.

“There’s a real appetite… to have those conversations—not just with each other, but with teachers and with parents,” Owen said.

Building a connected model

Work with schools in the UK now includes international partners, with classrooms in Europe, the Middle East, and Asia beginning to take part. Additional school networks are in discussion.

As more schools install monitors and publish data, the project is gradually forming a distributed network of classrooms, each contributing its own data and perspective.

Because the same monitoring and platform infrastructure can be used across regions, schools are able to participate in a shared system without needing to adapt the technical setup each time. Over time, individual data points begin to form a connected system across schools.

For EarthMuseum Learn, the goal is not simply to grow, but to build something that keeps those classrooms connected rather than operating in isolation.

EarthMuseum Learn offers one way to bring environmental learning closer to students’ daily experience.

By combining real-time monitoring with classroom teaching and global data sharing, the program gives students a way to follow air quality through observation, comparison, and discussion. It also suggests a different way of teaching these topics—one where classrooms are connected through shared data and analysis instead of working in isolation.

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? 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). 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 (1). 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: Aheri, Ahmedabad, Agra, Delhi, Dhanbad, Indore, Jaisalmer, Jodhpur, Kota, Macherla, Nagpur, Nanded, Prayagraj, Raipur, Sambalpur and Solapur. Pakistan: Bahawalpur, Dadu, Hyderabad, Lahore, Multan, Rahim Yar Khan, Sahiwal, Sibi, Sukkur and Turbat. Afghanistan: Lashkar Gah and Mirabad. How long will the heatwave last? The heatwave began in early April 2026 and is expected to persist through the summer months. In India, forecasts indicate above-normal heatwave days throughout the April-June period. The India Meteorological Department chief stated there will be an increased number of heatwave conditions along the east coast states and Gujarat by about four to five days into the month of May (2). Pakistan's meteorological department (PMD) has warned of continued heatwave conditions across central and upper Sindh for several days to weeks. This long-term pattern means temperatures will likely remain above 100°F (38°C) throughout the summer season across much of the region, until the monsoon season provides relief (3). In Afghanistan, summer heat typically lasts from May through September, with temperatures in southern regions like Kandahar reaching 36-43°C (97-109°F). It is possible that a strong El Niño projected for this summer may also contribute to more intense, longer-lasting heat waves and dry weather in South Asia (4). Are there any alerts in place? Multiple heat alerts are active across South Asia. In India, several regions in Gujarat were placed under orange alert status, indicating heatwave conditions and heightened probability of heat-related illnesses (5). The Uttar Pradesh Government issued directives for hospitals to prepare for increased cases of heat-related illnesses and alerted veterinarian teams to ensure adequate shelter and water for livestock. The India Meteorological Department continues issuing warnings for severe heatwave conditions in western regions and along the coast. In Pakistan, the PMD forecast continued heatwave conditions and urged citizens to avoid exposure to direct sunlight during daytime and remain 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.","

Santiago records AQI above 160, ranking among the world's most polluted cities. Stagnant air, firewood burning, and valley topography are driving this rare spike. Learn more.

","Is the air quality good in Santiago? As of May 14, 2026, at 1:30 AM (local time, GMT-4), air quality in Santiago, Chile, has worsened sharply over the past several hours due to a build-up of fine particulate matter combined with poor atmospheric dispersion. The AQI is above 160, classified as \"unhealthy,\" with PM2.5 as the dominant pollutant. These conditions pose serious health risks, particularly for children, the elderly, and those with respiratory or cardiovascular conditions. For a complete, real-time view of current pollution levels, see Santiago’s air quality map. While air quality in Santiago is typically moderate, today’s conditions are very poor, with PM2.5 levels reaching 13 times the WHO annual guideline of 5 µg/m³. By comparison, Santiago’s 2025 annual average PM2.5 concentration was 18.9 µg/m³, equivalent to an AQI of 65.

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

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.

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

Himalayan salt lamps DO NOT purify indoor air.

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

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

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

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

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

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

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

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

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

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

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

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

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

There are two main types of ozone:

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

Negative ionization can generate tropospheric ozone indoors. While stratospheric ozone has no interaction with us in the lower atmosphere, ground-level ozone is far more harmful when it builds up to high levels.

This is ground-level ozone, and even though it’s a typical feature of modern life, extensive research shows that it causes a plethora of immediate symptoms, including:

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

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

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

So what’s so special about Himalayan salt?

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

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

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

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

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

Are scented candles bad for you?

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

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

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

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

Paraffin wax

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

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

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

alkenes
acetone
benzene
toluene

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

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

Is burning candles bad for you?

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

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

Ultrafine particles are associated with severe health issues, including:

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

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

Chemical fragrances

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

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

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

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

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

Cored wicks

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

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

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

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

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

Safer alternatives

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

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

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

The takeaway

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

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

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

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

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

Nairobi's leap towards cleaner air

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

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

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

Local expertise, global resources drive innovation

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

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

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

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

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

The challenge of air quality monitoring in Africa

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

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

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

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.","

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.
