Air pollution is a global problem, and the World Health Organization estimates that nearly 1 in 8 deaths worldwide can be attributed to it. The particulate matter in polluted air can implant itself in our lungs and enter our bloodstream, leading to serious lung or respiratory issues and even cancer. To protect yourself from particulate matter, sulfur dioxide, and carbon monoxide in the air, you should wear an anti-pollution mask. When choosing a mask, look for one with a rating of N90, N95, or N99, which stands for the percentage of fine particles the mask has been tested to block. If you have impaired lung function, check with your doctor before using a respirator, as they can make breathing more difficult.

What You'll Learn
Ensure a good fit: Check for a seal and if you have a beard
To ensure a good fit, you must check for a seal. A good seal will ensure that your mask is effective in reducing exposure to air pollution. There are two ways to check for a seal: the positive pressure method and the negative pressure method.
The positive pressure method involves closing off the exhalation valve and exhaling gently into the mask. If the mask has a good seal, you should be able to build up slight positive pressure inside the mask without any air leaking out.
The negative pressure method involves covering the inlet opening of the canister or cartridge(s) by using your palm or replacing the filter seal(s). Inhale gently so that the mask collapses slightly and hold your breath for ten seconds. If the mask has a good seal, it will be difficult to inhale. Alternatively, the respirator manufacturer may recommend their own procedures for performing a user seal check, which you can follow instead.
It is important to note that individuals with beards may not be able to achieve an adequately tight fit around the nose and mouth, which is necessary for the mask to be effective.

Choose the right mask: N95, KN95/FFP2, or N99?
When choosing a pollution mask, it's important to select one that is effective at filtering out pollutants and fits well to your face. The most common types of pollution masks are N95, KN95/FFP2, and N99. Here's a breakdown of each type to help you choose the right mask for your needs:
N95 masks are the US standard for respirator masks and are rated by the National Institute for Occupational Safety and Health (NIOSH). These masks are designed to filter out at least 95% of airborne particles larger than 0.3 microns, which includes fine particles such as PM2.5 air pollution. N95 masks provide effective protection against respiratory diseases and airborne particles. They are ideal for healthcare and industrial workers dealing with extremely contagious diseases, such as COVID-19. However, they can be uncomfortable due to their tight fit and may be more expensive than other options.
KN95 masks are the Chinese standard for masks and are widely considered equivalent to N95 masks in terms of filtration efficiency. They are required to filter at least 95% of particles and are tested for their filtration efficiency at capturing salt particles (NaCl). KN95 masks may offer better breathability than N95 masks due to slightly looser requirements for pressure drop during inhalation and exhalation. They are also often more affordable than N95 masks. However, it can be more difficult to verify the authenticity of KN95 masks, and they may not be as readily available in some regions.
FFP2 masks are the European standard for masks and are also considered equivalent to N95 and KN95 masks in terms of filtration efficiency. FFP2 masks must filter at least 94% of airborne particles and follow the European EN 149 standard. They often provide better breathability than NIOSH-certified masks and are designed for public use, making them a comfortable option. FFP2 masks may be more readily available in Europe and are a good choice if you're looking for a well-tested and certified mask.
N99 masks are a more sensitive version of the N95 masks, filtering more than 99% of airborne particles. They are ideal for individuals who want maximum protection against particle pollution. N99 masks may be more expensive and less readily available, but they offer the highest level of protection among commonly used masks.
When choosing between N95, KN95/FFP2, and N99 masks, consider factors such as availability, cost, comfort, and your specific protection needs. Remember, the key to any mask's effectiveness is a good seal that fits well to your face to prevent air leakage.

When to wear: Understand AQI scores and PM2.5 levels
When to wear a pollution mask depends on the air quality and your exposure to it. Air quality is often measured using the Air Quality Index (AQI), which is a metric that takes into account several types of air pollutants, including PM2.5 particulate matter. PM2.5 refers to tiny particles in the air that are 2.5 microns or less in width. Due to their minuscule size, these particles can be inhaled and lodge themselves deep in your lungs, potentially causing serious health issues.
The AQI provides a numerical value that indicates the level of air pollution at a given time and location. It is calculated based on the concentrations of various pollutants in the air, including PM2.5. Generally, an AQI value below 50 is considered good, indicating moderate air quality with a low health risk. Values between 50 and 100 are acceptable, but sensitive groups may experience minor respiratory issues. When the AQI climbs above 100, the air quality is considered unhealthy, and protective measures such as wearing masks are recommended.
In areas with consistently poor air quality, such as highly industrialized or urbanized regions, it is advisable to regularly check the AQI and PM2.5 levels. You can do this through local news sources, government websites, or mobile applications that provide real-time air quality data. By staying informed about the air quality, you can make informed decisions about when to wear a pollution mask.
It is essential to recognize that pollution masks are not a perfect solution. While they offer protection, they can be uncomfortable and may not completely block out all pollutants, especially if they do not fit tightly to your face. Nonetheless, in areas of hazardous air quality, wearing a mask can provide a significant level of protection, reducing the number of pollutants that enter your respiratory system.

Why wear: To protect against air pollution and infections
Air pollution is a serious issue that affects people globally. The World Health Organization (WHO) estimates that nearly 1 in 8 deaths worldwide can be attributed to air pollution. Long-term exposure to fine particulate matter, especially PM2.5, has been linked to an increased risk of severe health issues, including lung cancer, heart disease, and respiratory infections.
To protect yourself from air pollution and its associated health risks, wearing an effective pollution mask is highly recommended. Masks like the N95/KN95/FFP2 are highly effective in blocking fine particles and have been shown to reduce the risk of exposure to PM2.5 and other airborne pollutants. These masks are designed to filter out both big and small particulate matter, including liquids, and can significantly reduce the chances of respiratory issues and infections.
It is important to note that not all masks are created equal. While surgical, cloth, or bandana masks may provide some protection, they are not as effective as N95/KN95/FFP2 masks. Additionally, masks with poor facial fit can allow polluted air to leak in, reducing their overall effectiveness. When choosing a mask, ensure it fits snugly over your nose and mouth, with a good seal to prevent unfiltered air from leaking in.
Wearing a mask during airborne infectious disease outbreaks, such as COVID-19, is also crucial. Masks act as a barrier, blocking droplets and germs, and can help protect against the spread of viruses and bacteria. Public health agencies strongly recommend wearing masks in high-risk environments, such as shared offices, classrooms, and public places, to reduce exposure to harmful airborne infections.
In summary, wearing a well-fitted, high-quality pollution mask is an effective way to protect yourself from air pollution and infections. By following the recommendations of public health agencies and choosing the right type of mask, you can significantly reduce your exposure to harmful pollutants and infectious agents.
