Not covid, but another great reason to keep masks on hand: Fine particulate matter increases all sorts of other health issues like asthma, high blood pressure, some cancers, and even strokes. Pollution is just as bad for you as covid in some senses.

By Alden Woods and Kiyomi Taguchi

As Baby Boomers hit retirement, about 1 in 6 Americans is now over the age of 65. The number of Americans living with dementia is projected to skyrocket — but the proportion of older Americans who develop dementia has actually decreased. The exact reason why is uncertain, but various lifestyle and environmental factors can influence a person’s risk of cognitive decline.

One recently discovered risk is air pollution. Studies have linked exposure to a type of air pollution called fine particulate matter, or PM2.5, with an increased risk of developing dementia, and researchers suspect that some sources of PM2.5 may pose a greater risk than others.

New research led by the University of Washington found that wildfire smoke is especially hazardous. An analysis of the health care records of 1.2 million Southern California residents found that higher long-term smoke exposure was associated with a significant increase in the odds that a person would be diagnosed with dementia.

The researchers presented their findings at the Alzheimer’s Association International Conference in July and published the full study Nov. 25 in JAMA Neurology.

“There have been studies that have found total PM2.5 is related to people developing dementia, but no one had looked specifically at wildfire PM2.5,” said lead author Joan Casey, a UW associate professor of environmental & occupational health sciences. “Wildfire smoke is a different animal, in that it’s much spikier. There are many days where there’s no wildfire smoke, and there are some days where exposure is really, really extreme.”

Researchers analyzed the health records of 1.2 million members aged 60 and older of Kaiser Permanente Southern California between 2008 and 2019, all of whom were free from dementia at the start of the study period. They estimated each person’s long-term exposure to both wildfire and non-wildfire PM2.5 as a three-year rolling average, and then identified people who received a dementia diagnosis.

Researchers found that for every 1 microgram per cubic meter (µg/m3) increase in three-year average wildfire PM2.5 concentration, the odds of a dementia diagnosis increased by 18%. Exposure to non-wildfire PM2.5 also increased a person’s risk of dementia, but to a much lesser degree.

“One microgram per meter cubed might sound fairly small, but we have to think about how people are exposed to wildfire smoke,” Casey said. “Most days they aren’t exposed at all, so this might represent a few days of exposure at a concentration of something like 300 µg/m3, where the AQI is over 200 in someone’s community. When you think about it, it’s actually a few really severe wildfire smoke days that might translate into increased risk.”

That risk further increased among racialized people and those living in high-poverty census tracts, following long-term trends in which vulnerable populations often experience disproportionate effects of environmental hazards. The authors suggested that disparities might be related to lower-quality housing, which can increase the amount of smoke that enters people’s homes, or lower-income families’ inability to afford air filtration systems.

The study period does not include the summers of 2020 and 2021, which produced the most extreme wildfire seasons recorded in California. The climate crisis has drastically increased the frequency and severity of wildfires across the American West, introducing “smoke season” in many West Coast regions The influx of smoke has chipped away at air quality improvements made over the last century.

“The main culprit here is climate change,” Casey said. “It’s a global problem. While individuals can protect themselves with air filters and masks, we need a global solution to climate change. It’s going to have to be many-pronged — many people have to be involved to solve this highly complex problem.”

🔍 The Reality Check: How Bad Is It?

According to multiple air quality index (AQI) reports, Kathmandu frequently ranks among the most polluted cities in the world. During winter months, the AQI often crosses 200–300, which is categorized as "Very Unhealthy."

Main Pollutants:

PM2.5 and PM10 particles

Vehicle emissions

Construction dust

Industrial smoke

Open garbage burning

These fine particles are small enough to enter your lungs and even your bloodstream, causing respiratory issues, heart disease, and even premature death.

🚗 What’s Causing This Pollution?

1. Traffic Congestion Old and unregulated vehicles release massive amounts of smoke and carbon emissions. Kathmandu’s narrow roads and increasing number of vehicles only add to the chaos.

2. Urban Construction With the city expanding rapidly, construction activities release high levels of dust and particulate matter into the air.

3. Industrial Growth Factories located on the outskirts of the valley emit toxic gases without proper filtration or regulation.

4. Waste Management Issues Open burning of garbage, plastics, and other household waste continues to pollute the air, especially in densely populated areas.

😷 Health Effects on the Public

The consequences are more than just occasional coughs.

Increased cases of asthma and bronchitis

Eye irritation and headaches

Higher risk of lung cancer and cardiovascular diseases

Reduced immunity, especially in children and the elderly

According to health experts, long-term exposure to polluted air is equivalent to smoking multiple cigarettes a day.

💡 What Can Be Done?

1. Promote Public Transport: More buses, electric vehicles, and better routes can reduce the number of private vehicles.

2. Plant More Trees: Urban greenery can act as a natural filter and improve air quality over time.

3. Enforce Emission Standards: Regulate older vehicles and force industries to follow emission guidelines.

4. Raise Awareness: Educating the public on waste disposal, vehicle maintenance, and the importance of masks can go a long way.

5. Government Action: Policies need to be stricter, better implemented, and transparent. It’s time to prioritize people’s health over unchecked urbanization.

🏁 Final Thoughts

Air pollution in Kathmandu is no longer just an environmental issue—it’s a public health crisis. While progress and development are important, they should not come at the cost of the air we breathe.

Let’s not wait until it’s too late. Every small action—whether it’s choosing to walk, planting a tree, or speaking up—can contribute to a cleaner Kathmandu.

if anyone is looking for something to make their air a little more breathable and has the money for things, here are the tools i wish i’d had before wildfire smoke ruined my lungs:

You want a mask. Respro remains my go-to. Note that this is the specific type of filter you want for whatever mask shell you purchase—charcoal filter + hepa.

Why HEPA? Because you want things rated PM2.5 (that’s rated for particulate matter 2.5 microns or less in diameter. That’s small enough to get into your bloodstream after you inhale it and cause the kind of damage that gave me, a person with no family history of asthma, absolutely shitty asthma and chronic pain on top of it.

Any amount of work you’ll be doing outside? Wear a mask. Wear a mask, wear a mask, wear a mask. I don’t know if KN-95s for viruses will work as well for smoke as things like a respro, but if it’s what you’ve got, wear it, because that’s better than nothing.

You might also be able to find PM2.5-rated masks at hardware stores, in the US.

You want the Coway Airmega AP-1512HH Mighty. Packs a hell of a punch cleaning up your air. Keep it in whatever room of your house you happen to be in, but especially the room you sleep in. Sleeping in smoke will fuck you up, and irritated lungs will keep you from sleeping, which will make everything worse and less comfortable, which is a vicious cycle.

Always have to mention Corsi-Rosenthal boxes. They’re basically DIY HEPA filters. While they often cost less than manufactured air filters like the Coway, the cost of the RIGHT materials is in total not a ton less expensive than the Coway (although it still was less expensive last I checked) and the Coway allows you to clean, maintain, change filters w/o building a new one etc. However, CR boxes are verified to work against viruses and smoke and have caught on in a big way as DIY air filtration to protect yourself from covid:

In all, the key words are “HEPA” and “PM2.5”

Respirators vs. Pollution Masks: Which Offers Better Protection?

As air quality continues to decline in many parts of the world, protecting yourself from harmful pollutants has become a priority. With rising AQI levels, the demand for protective gear like pollution masks and respirators has surged. However, choosing the right option can be confusing, especially when terms like anti pollution mask and respirator are often used interchangeably. In reality, these are distinct products with different purposes and levels of protection. In this blog, we’ll break down the differences between pollution masks and respirators, helping you decide which offers better protection for your needs, with insights from Nirvana Being, a trusted name in air quality solutions.

Understanding Pollution Masks

A pollution mask is designed to shield you from everyday environmental pollutants, such as dust, smog, and particulate matter (PM) like PM2.5, which are tiny particles harmful when inhaled over time. These masks are particularly popular in urban areas where traffic emissions and industrial activities contribute to poor air quality. Pollution masks are lightweight, affordable, and easy to wear, making them a practical choice for daily commutes or outdoor activities.

Most pollution masks are certified as N95 or N99, indicating their ability to filter out 95% or 99% of PM2.5 particles, respectively. They often feature air valves to channel exhaled air outward, preventing moisture buildup and reducing fogging around the nose or glasses. For instance, Nirvana Being offers high-quality pollution masks that prioritize comfort and filtration efficiency, ensuring you can breathe easier in polluted environments. These masks are ideal for individuals exposed to moderate levels of air pollution, such as city dwellers or cyclists.

However, pollution masks have limitations. They primarily filter particulate matter and are less effective against chemical gases, vapors, or biological contaminants. If you’re in an area with heavy industrial pollution or chemical exposure, a pollution mask may not provide sufficient protection.

Exploring Respirators

Respirators, on the other hand, are engineered for more hazardous environments. They are designed to protect against a broader range of airborne contaminants, including particulate matter, chemical fumes, gases, vapors, and even certain pathogens. Respirators are commonly used in occupational settings—think construction sites, chemical plants, or healthcare facilities—where workers face prolonged exposure to dangerous substances.

Respirators come in two main types: Air-Purifying Respirators (APRs) and Supplied-Air Respirators (SARs). APRs pass contaminated air through a filtering element to remove harmful particles or gases, while SARs provide a separate source of clean air. Depending on the model, respirators may offer advanced filtration systems, such as activated carbon layers, to neutralize chemical odors or toxic gases. They are typically certified with ratings like N95, N99, or even higher standards like P100, which block 99.97% of airborne particles.

While respirators provide superior protection, they are often bulkier, less comfortable for extended wear, and more expensive than pollution masks. They also require proper fitting to ensure an airtight seal, which can be a drawback for casual users.

Key Differences Between Pollution Masks and Respirators

Purpose and Protection Pollution masks focus on filtering particulate matter like dust and PM2.5, making them suitable for general outdoor use in polluted cities. Respirators, however, are built for high-risk environments, offering protection against a wider array of contaminants, including chemical gases and biological agents.

Comfort and Usability Pollution masks are lightweight and designed for daily wear, with features like adjustable straps and breathable materials. Respirators, due to their robust construction, may feel restrictive and require training for proper use.

Cost and Accessibility Pollution masks are widely available and budget-friendly, making them accessible to the average consumer. Respirators, especially advanced models, are pricier and often used in professional settings.

Certification and Standards Both may carry N95 or N99 certifications, but respirators often meet stricter occupational safety standards, ensuring reliability in extreme conditions.

Which Should You Choose?

The choice between a pollution mask and a respirator depends on your environment and exposure level. For most people navigating urban pollution—say, commuting through a smoggy city—a high-quality air pollution mask like those offered by Nirvana Being is sufficient. These masks effectively block harmful PM2.5 particles while remaining comfortable for daily use. Look for N95 or N99 certifications to ensure adequate filtration.

If you work in or frequently visit areas with chemical fumes, heavy industrial pollutants, or biohazards, a respirator is the better choice. It provides comprehensive protection but requires careful selection and fitting to be effective.

Final Thoughts

Both pollution masks and respirators play critical roles in safeguarding your health, but they serve different purposes. A pollution mask is your go-to for everyday protection against urban air quality challenges, while a respirator is essential for high-risk, hazardous environments. By understanding your needs and the level of exposure you face, you can make an informed decision. Brands like Nirvana Being offer reliable solutions to help you breathe cleaner air, whether you opt for a pollution mask or explore advanced protective gear. Prioritize your health, assess your surroundings, and choose wisely to stay protected in today’s polluted world.

Are Electrostatic Precipitators Effective for Dust Removal?

Electrostatic precipitators effective for dust removal, they are among the most efficient technologies available today. Electrostatic precipitators can remove up to 99% of dust particles from flue gases before they are released into the atmosphere. Their effectiveness depends on several factors, including particle size, gas composition, and proper maintenance.

How Electrostatic Precipitators Work

Electrostatic precipitators use electrical forces to remove dust and particulate matter from a gas stream. When polluted air passes through the ESP, dust particles are electrically charged by discharge electrodes. These charged particles then migrate to oppositely charged collection plates, where they are held until removed. This non-mechanical filtration process makes ESPs especially efficient in handling fine dust.

Benefits That Prove Their Effectiveness

Still wondering, are electrostatic precipitators effective for dust removal? Consider these advantages:

High efficiency for fine particles, including PM2.5 and smaller

Low-pressure drop, meaning minimal energy loss during operation

Continuous operation with minimal manual intervention

Suitable for high-temperature and high-pressure environments

These features make electrostatic precipitators a top choice for industries needing reliable dust removal, including cement plants, power stations, steel mills, and waste incinerators.

Comparison to Other Dust Collection Systems

It’s helpful to compare them to other methods. Compared to bag filters or wet scrubbers, ESPs offer a lower operational cost over time due to minimal maintenance and lower energy usage. They are also better suited for handling very small particles, making them ideal in settings where air purity is critical.

Limitations to Consider

While ESPs are highly effective, they may not perform optimally without proper maintenance or if the gas stream lacks sufficient particle loading. Also, their initial installation costs can be higher than other systems. Despite this, their long-term performance and durability make them a worthwhile investment.

Understanding Invisible Particles and Their Impact on Our World

In a world dominated by the visible, the unseen often holds more power than we realize. Invisible particles play a crucial role in various scientific, environmental, and technological applications. From the air we breathe to the cutting-edge advancements in nanotechnology, these microscopic entities impact our daily lives in more ways than we can imagine. At InvisibleParticles, we are committed to exploring the significance of these tiny but mighty components and how they shape our reality.

What Are Invisible Particles?

The term invisible particles refers to minuscule entities that are too small to be seen by the naked eye. These particles can exist in different forms, such as aerosols, nanoparticles, microscopic dust, and even quantum particles. While some are naturally occurring, others are man-made, playing significant roles in various industries, from medicine to environmental science.

The Role of Invisible Particles in Science and Technology

1. Air Quality and Pollution Control

One of the most common ways invisible particles impact our lives is through air quality. Particulate matter (PM) comprises tiny solid or liquid droplets suspended in the air, contributing to air pollution. PM2.5 and PM10 are two significant categories of airborne invisible particles that affect human health. At InvisibleParticles, we emphasize the importance of understanding and mitigating these pollutants to promote a healthier environment.

2. Nanotechnology and Medicine

Nanoparticles, a subset of invisible particles, have revolutionized modern medicine. These microscopic entities enable targeted drug delivery, improving treatment efficiency for diseases such as cancer. Scientists are also developing nanoscale biosensors that can detect diseases at an early stage, significantly enhancing diagnostic capabilities.

3. Environmental Science and Climate Change

Invisible particles play a crucial role in climate change. Aerosols, for example, influence global temperatures by reflecting or absorbing sunlight. Sulfate aerosols cool the Earth’s surface, while black carbon particles contribute to warming. At InvisibleParticles, we support research initiatives that study these effects and seek sustainable solutions to mitigate climate change.

4. Space Exploration

Beyond Earth, invisible particles hold great significance in space exploration. Cosmic dust, composed of minute particles, provides insights into the universe’s origins. Additionally, scientists study microgravity environments to understand how nanoparticles behave in space, influencing future interstellar travel and habitation.

The Hidden Dangers of Invisible Particles

While invisible particles contribute positively to scientific advancements, some pose serious risks. Exposure to harmful nanoparticles, particularly from industrial processes, can lead to respiratory issues, cardiovascular diseases, and even neurological disorders. Understanding these risks is crucial in developing safety regulations and protective measures.

At InvisibleParticles, we prioritize awareness and education about the potential hazards associated with airborne particles and other microscopic pollutants. We advocate for stringent air quality controls and workplace safety measures to ensure public health and well-being.

Innovations and Solutions by InvisibleParticles

Recognizing the impact of invisible particles, we at InvisibleParticles are dedicated to providing solutions that enhance our understanding and control of these microscopic entities. Our initiatives include:

Advanced Air Filtration Systems: We develop state-of-the-art filtration solutions that effectively capture harmful particulate matter, improving indoor and outdoor air quality.

Nanotechnology Research: Our team is engaged in cutting-edge research to harness the power of nanoparticles for medical and industrial applications.

Environmental Monitoring: We provide innovative sensor technology that detects invisible particles in the atmosphere, allowing for real-time pollution tracking and mitigation.

The Future of Invisible Particles

The study of invisible particles is still in its infancy, yet it holds immense potential for the future. With advancements in quantum physics, artificial intelligence, and nanotechnology, scientists are uncovering new ways to utilize and control these microscopic forces. InvisibleParticles is at the forefront of this journey, pushing the boundaries of what is possible and contributing to a more sustainable and technologically advanced world.

As Los Angeles battles recent wildfires, air quality across the region has plummeted to hazardous levels. Based on authoritative recommendations, many have turned to air filters and purifiers as a defense against smoke pollution. But what if these solutions are not as protective as suggested? It turns out there are widespread misconceptions about wildfire smoke and its hazards, as well as the effectiveness of air filtration in protecting human health against wildfire smoke because this has been an understudied and consequently overlooked area of research. A scientific paper by Metalmark researchers uncovers critical flaws in current filter technologies and their assessment when it comes to capturing dangerous wildfire smoke particles. "There are a number of misconceptions about the size and behavior of particles generated by wildfires," explains Sissi Liu, CEO and co-founder of Metalmark Innovations. "This leads to a false sense of security when recommending filters tested using methods that don't account for the unique properties of smoke." The recent fires in Los Angeles have blanketed the region in thick smoke. The South Coast Air Quality Management District has reported PM2.5 levels up to 5 times the federal standard, prompting warnings to stay indoors. Understanding Wildfire Smoke and PM2.5 Wildfire smoke consists of fine particulate matter (PM) known as PM2.5, which includes particles smaller than 2.5 microns in diameter — approximately 1/30 the diameter of a human hair and smaller. While PM2.5 is a regulatory benchmark, this characterization fails to convey the size distribution of smoke particles. Practically all wildfire smoke particles are much smaller, averaging about 0.1-0.3 microns — roughly 1/350 the diameter of a human hair and smaller. This distinction is critical because smaller particles carrying toxic chemicals are more harmful, penetrating deep into the lungs and more capable of entering the bloodstream. Key Misconceptions About Wildfire Smoke Misconception #1. Smoke Particles Are Larger Than 1 Micron Wildfire smoke particles are predominantly submicron in size, forming as ultrafine particles (UFPs) immediately during combustion. Over tens of minutes, these particles stabilize between 0.1-0.3 microns, allowing them to travel vast distances without significant size changes. This stability means that harmful smoke particles from fires in Los Angeles can affect air quality across the US West Coast and the rest of the US. Misconception #2. Wildfire Smoke Is Just Like Any Other PM2.5 Unlike urban PM2.5, which often originates from traffic and industrial emissions, wildfire smoke is composed mainly of organic carbon compounds. Fires in the wildland-urban interface (WUI) include the combustion of biomass, building materials, vehicles, electronics, batteries, and more. They introduce additional toxins, including hydrogen cyanide, hydrogen fluoride, hydrogen chloride, isocyanates, dioxins, furans, chlorine, various toxic organic compounds (e.g., benzene, toluene, xylenes, styrene, formaldehyde), heavy metals (e.g., lead, chromium, cadmium, arsenic), and polycyclic aromatic hydrocarbons (PAHs). While some toxins, such as highly volatile formaldehyde, are transported in gaseous form, many of these toxic substances hitch a ride on smoke particles, often reported at diameters 200-300 nm or below, making them hazardous over long distances. Moreover, wildfire smoke aerosols are dynamic, containing semi-volatile organic compounds that can evaporate and react to form secondary pollutants, further degrading air quality and posing ongoing health threats. Smoke is even known to spread pathogens, contributing to rising cases of Valley Fever, for example. Misconception #3. Smoke Is Harmless If You’re Far from the Fire Smoke’s impact from large-scale extends far beyond the immediate vicinity of the fire. During the 2023 Canadian wildfires, for example, smoke traveled thousands of miles and caused hazardous air quality as far away as New York City and Atlanta. Despite the distance, the particle size and toxicity remain largely unchanged, leading to increased respiratory and cardiovascular health issues in affected regions. Research shows that faraway smoke increases cardiopulmonary disease and is associated with up to 1000-fold the premature deaths of the fires themselves. Misconception #4. Staying Indoors Provides Adequate Protection Many believe that staying indoors is a sufficient safeguard against wildfire smoke. However, smoke particles infiltrate buildings through gaps, ventilation systems, and even closed windows. Additionally, indoor air quality can degrade due to formaldehyde, ozone, and other chemicals — common byproducts of wildfires that penetrate indoors. Misconception #5. Current MERV-13 and HEPA Filters Provide Sufficient Protection While MERV-13 and HEPA filters are touted as effective solutions, they have limitations: Suboptimal Performance for Submicron Particles: Most HVAC filters, including MERV 13 and higher grades, are the least effective at capturing particles in the 0.1-0.3 micron range — precisely the size of wildfire smoke particles.
