Air pollution is a serious issue, causing a range of health issues, including lung and heart problems, and even potentially leading to neurological issues and peripheral neuropathy. Face masks are one way to protect yourself from the negative health impacts of air pollution. The effectiveness of a mask depends on the type of pollutants, the mask type, and how it is used. N95 masks are a popular choice, as they are affordable and can filter out 95% of airborne particles larger than 0.3 microns. However, N95 masks do not filter out harmful gases, so combining them with additional features like activated charcoal can further reduce exposure to gases. Other masks on the market include the Respro® Masks, which are suitable for urban sports environments, and the Vogmask™, which uses microfiber filtration fabric to provide an N99 rating.

N95 masks are the most popular and affordable option for protection against air pollution
Air pollution has a detrimental impact on human health, causing serious complications including lung cancer, heart disease, and stroke. Even minor exposure to air pollution can have a negative impact on the lungs, heart, and brain. As a result, pollution masks have become increasingly popular as a way to protect oneself from the harmful effects of air pollution.
The effectiveness of N95 masks in filtering out particles smaller than 0.3 microns is reduced. Additionally, N95 masks do not filter out harmful gases present in air pollution. To combat this, N95 masks can be combined with additional features such as activated charcoal, which helps reduce exposure to gases. However, these masks are more expensive.
It is important to note that the effectiveness of N95 masks depends on the type of pollutants, the quality of the filter, the number of filter layers, and how well the mask fits an individual's face. Evidence suggests that even with N95 masks, there could be leakage between the edge of the mask and a person's face, depending on factors such as face shape and whether the person has facial hair.
Overall, N95 masks are a popular and affordable option for protection against air pollution, offering a good balance between performance and cost.

Face masks with N99 ratings are more effective at blocking out smaller particles
Face masks are considered an effective way to protect oneself from the harmful effects of air pollution. According to research, even minor exposure to air pollution can negatively impact the lungs, heart, and brain. Face masks with N95 ratings are the most commonly used masks to protect against pollution particles. N95 masks are designed to filter out at least 95% of airborne particles larger than 0.3 microns, including large respiratory droplets and smaller aerosols. They are also effective against wildfire smoke.
However, face masks with N99 ratings are more effective at blocking out smaller particles. N99 masks should block 99% of particles larger than 0.3 microns. Vogmask™, for example, uses microfiber filtration fabric to provide an N99 rating. In Europe, N99 masks are classified as FFP3, which are equivalent to FFP2 masks in the performance of their functions. FFP2 masks filter 94% of particles down to 0.3 microns, which is similar to N95 masks.
The effectiveness of any face mask depends on various factors, including particle size and source, mask type, face shape, and a person's breathing rate. Evidence suggests that even short-term exposure to ultrafine particles can lead to lung inflammation and cardiovascular changes. Therefore, it is crucial to select a face mask that considers the quality of the filter, the number of different filter layers, and how well it fits. A real person may be exposed to more pollution than a dummy head used in studies due to leakage between the edge of the mask and the person's face.

The effectiveness of a face mask depends on the type of pollutants, the mask, and how it's used
Face masks are considered an effective way to protect oneself from the ill effects of air pollution. Research has shown that even minor exposure to air pollution can negatively impact the lungs, heart, and even the brain. Air pollution is made up of particles and gases. Gases include ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and volatile organic compounds. While gases can be harmful, research indicates that we should be more concerned about the negative health impacts of fine particles—those under 2.5 microns in size.
The effectiveness of any face mask is difficult to measure, as many factors can influence how well a mask works. These factors include particle size and source, mask type, face shape, and a person's breathing rate. For example, a person with a larger face or facial hair may experience leakage between the edge of the mask and their face, reducing the mask's effectiveness.
When selecting a face mask, it's important to consider the quality of the filter, the number of different filter layers, and how well it fits. Masks with a rating of N95 or N99 will best protect against pollution particles. These ratings indicate that the mask can block 95% or 99% of particles, respectively. In Europe, these masks are classified as FFP1, FFP2, and FFP3, with FFP1 being equivalent to N95, FFP2 between N95 and N99, and FFP3 the same as N99.
While face masks can offer protection against air pollution, it's important to take other steps to reduce exposure, such as spending less time outdoors when air quality is poor and using indoor air purifiers.

Face masks with activated charcoal can help reduce exposure to gases
Face masks are designed to protect against harmful particles and gases in the air, which can have negative health effects on the lungs, heart, and brain. While N95 masks are commonly used to filter out particles, they do not remove harmful gases. This is where masks with activated charcoal come in—they can help reduce exposure to gases and are more effective than N95 masks in this regard.
Activated charcoal is a form of carbon that has been treated to increase its absorbency. It is often used in air and water filters due to its ability to attract and trap particles and gases. When incorporated into face masks, activated charcoal can help reduce exposure to harmful gases such as carbon monoxide, sulfur dioxide, ozone, nitrogen dioxide, and volatile organic compounds (VOCs).
The effectiveness of a face mask depends on various factors, including the type of pollutant, the mask type, face shape, and a person's breathing rate. It's important to ensure that the mask has a good seal around the face to minimize leakage. Masks with activated charcoal are generally more expensive than N95 masks, and it's important to identify which gases they are designed to filter and their effectiveness in doing so.
Some studies have shown that wearing N95 masks can have positive effects on blood pressure and oxygen delivery to the heart, indicating that masks can help reduce the short-term exposure effects of air pollution. However, there have been limited studies on the effectiveness of masks with activated charcoal, and more research is needed to fully understand their impact on health.
Overall, face masks with activated charcoal can be a useful tool to reduce exposure to harmful gases in polluted air, but they should be used in conjunction with other measures to ensure comprehensive protection.

Face masks are especially useful in urban sports environments, like biking in the city
When selecting a face mask, it is important to consider the quality of the filter, the number of different filter layers, and how well it fits. Dr Gary Fuller from KCL recommends using a mask with sub-micron filters to filter out small particles, and ensuring a snug fit on the face. Masks with an N95 or N99 rating are considered to offer the best protection against pollution particles. N95 masks filter out at least 95% of airborne particles larger than 0.3 microns, while N99 masks should block 99% of particles.
Respro and Totobobo are two companies that produce masks with sub-micron filters, and their products are commonly used by cyclists in the UK. The Respro City mask is the most popular, but some users have reported struggling to breathe while wearing it. The Totobobo mask is also designed with two valves for easier breathing, and its filter lifespan is said to be 69 hours. Another option is the BioLogic mask, which is made from industrial-grade rubber and plastic and features two replaceable carbon filters and dual "inhale ports" for easier breathing.
While face masks can offer some protection against pollution, it is important to consider other factors such as taking alternative routes along back roads where pollution levels tend to be lower.
