Air pollution is a growing concern for people around the world, with many donning face masks to protect themselves from poor air quality. The most common face masks worn are surgical masks, which are designed to prevent the spread of bodily fluids and block microbes. However, these masks are ineffective against haze, smog, or general air pollution and do not offer an airtight fit. Respiratory pollution masks, such as the N95 filtering facepiece respirator, are designed to filter out 95% of airborne particles and form a tight seal over the mouth and nose. While these masks can provide protection against particulate matter, they are ineffective against chemicals, gases, or vapors, and can be uncomfortable in hot weather. Cloth masks have also been used for protection, but their effectiveness is generally lower than that of medical masks and respirators. Overall, while respiratory pollution masks can provide some protection, they are not a perfect solution, and the uncontrolled rise in vehicular emissions and other sources of air pollution remains a serious problem.

N95 masks are proven to reduce inhaled exposure by 95%
N95 masks, if officially certified by the National Institute for Occupational Safety and Health (NIOSH) in the USA, have passed the fit-test results on a human face. During this test, a person wears the mask for about 15 minutes, moving around in many positions, with the mask attached to special machines that record the concentration inside and outside the mask. If the air inside the mask is more than 95% reduced in particles, that mask passes the N95 test.
N95 masks are widely available and relatively comfortable. They can be useful in environments with poor air quality or pollution, such as in public places, under smoke conditions from a wildfire, when cleaning a mouldy area, doing dusty or pollen-heavy yard work, or during messy renovation work at home.
However, it is important to note that N95 masks do not protect against chemicals, gases, or vapours, and are intended only for low hazard levels. They also do not provide "absorbent capability", and leakage can occur, even if the mask is properly fitted. People with impaired lung function should check with their doctor before using any respirator, including N95 masks, as they can make breathing slightly more difficult.

Cloth masks may provide some protection if well-designed and used correctly
Cloth masks have been used in healthcare and community settings for protection against respiratory infections. Their use during the COVID-19 pandemic has been a topic of debate, as the filtration effectiveness of cloth masks is generally lower than that of medical masks and respirators. However, cloth masks may offer some protection if they are well-designed and used correctly.
The effectiveness of cloth masks can be enhanced by certain design features. For instance, multilayer cloth masks that are designed to fit snugly around the face and are made of water-resistant fabric with a high thread count and fine weave may provide reasonable protection. Historically, cloth masks have been used during various epidemics and observational studies have found them to be effective. For example, during the severe acute respiratory syndrome outbreak in China, cotton masks were widely used, and healthcare workers and the general public observed positive outcomes.
It is important to note that the primary function of masks is to filter out certain particles from the air. While cloth masks can provide some level of protection, they may not block all toxic substances in the air. They are effective against particulate matter but may not protect against nitrates, sulphur dioxide, carbon monoxide, lead, and other gaseous pollutants. Therefore, it is recommended to choose the most protective mask available and ensure a proper fit to maximize the benefits.
Additionally, it is worth mentioning that respirator masks, such as the N95 or KN95, offer higher levels of protection than cloth masks. These respirators are designed to filter out at least 95% of airborne particles and are commonly used in hospitals to protect against infectious agents. However, they do not provide protection against chemicals, gases, or vapors and are intended for low-hazard environments. People with impaired lung function should consult a doctor before using respirators, as they can make breathing slightly more challenging.

Surgical masks are ineffective against haze, smog, or general air pollution
Face masks, including the popular 3-ply surgical mask, are designed to prevent the user from transferring bodily fluids to other people when they sneeze or cough and to prevent the user from touching their mouth or nose with contaminated hands. They have a central filter layer designed to trap microbes, not air pollutants. Surgical masks are ineffective against haze, smog, or general air pollution because they do not offer an airtight fit around the nose and mouth, allowing air to come in from the sides when inhaling.
The Health Ministry advisory on the usage of personal protection during the haze confirms that surgical masks will not prevent one from inhaling small airborne particles. These masks are only useful for protection against larger particles that irritate, and so may be useful for some exposure outdoors, such as when riding a bike. Surgical masks are also ineffective once damp or wet, or after coughing or sneezing into them, and they need to be changed frequently.
To protect against haze, smog, or general air pollution, N95 respirators are recommended. N95 respirators are available in surgical and industrial versions, and both work equally well to filter out air pollutants. N95 respirators are capable of filtering out PM2.5 particles, which are smaller than 2.5 microns in size and are especially dangerous because they can be breathed deep into the lungs, causing long-term health effects. N95 masks, if officially certified by the National Institute for Occupational Safety and Health (NIOSH) in the USA, have been proven by independent labs to reduce inhaled exposure by at least 95%.
KN95 and FFP2 masks are equivalent to the N95 standard for particles down to 0.3 microns. These masks have also been proven effective in reducing the transmission of airborne COVID-19.

Respirator masks protect against air pollution, smoke, dust, and fumes
Respirator masks are designed to protect against air pollution, smoke, dust, and fumes. The N95 respirator, for example, filters out 95% of airborne particles, including smoke, dust, and fumes. It is important to note that respirators only work effectively when worn correctly, forming a tight seal over the mouth and nose so that inhaled air passes through the filter.
The N95 respirator is widely recognised as a reliable protection against air pollution. It is capable of filtering out PM2.5 particles, which are smaller than 2.5 microns and are known to cause major inflammatory damage, leading to heart disease, lung disease, and cancers. By reducing exposure to these harmful particles, N95 respirators offer a tangible health benefit to users.
In addition to the N95 respirator, there are other effective options available. The 3M 6502QL/49489 Rugged Comfort Quick Latch Half Facepiece Reusable Respirator, for instance, is a comfortable and adjustable model that provides over 99% filtration of airborne particles. It also protects against paint fumes and certain volatile gases.
Another notable option is the 3M 2097 filter, a P100-rated filter capable of capturing at least 99.97% of airborne particles, including smoke, petrochemical fumes, and some caustic vapors. This filter offers protection equivalent to hard-plastic cartridge filters, providing effective defence against air pollutants.
While respirator masks offer significant protection, it is important to follow proper usage instructions. For instance, it is crucial to ensure the mask is worn correctly, creating a tight seal to prevent air leakage. Additionally, in hot weather, sweat and spittle can accumulate inside the mask, creating a health risk. Thus, proper care and maintenance of the respirator mask are essential for optimal protection.

Masks don't protect against all toxins, like nitrates, sulphur dioxide, and carbon monoxide
While respiratory masks are an effective way to protect against harmful pollutants, they do not guard against all toxins. Notably, masks are ineffective against gases like nitrates, sulphur dioxide, and carbon monoxide.
The PMO.3 mask, for example, is a popular anti-pollution mask due to its robust filtration system and comfort. It is designed to protect against airborne particles and uses advanced filtration technology to block out pollutants as small as 0.3 microns in diameter. However, its focus is on particulate matter, allergens, and microorganisms, rather than gaseous toxins.
The N95 respirator is another commonly used mask that offers significant protection from exposure to carbon monoxide but does not work against gases. It is effective at filtering out dust, fumes, mists, aerosols, and smoke particulates, and biological particles. However, it is not a foolproof solution for gaseous toxins.
It is important to recognize that masks were initially designed to safeguard industrial and health workers against specific occupational hazards and are not a comprehensive solution to air pollution. The rise in vehicular emissions, smoke from open burning, and industrial processes means that even with masks, we may still be exposed to harmful toxins.
Therefore, while respiratory masks offer a level of protection against particulate pollutants, they do not provide complete protection against all toxins in the air, especially gaseous compounds like nitrates, sulphur dioxide, and carbon monoxide.
