What You'll Learn
Effectiveness of anti-pollution masks
The effectiveness of anti-pollution masks depends on several factors, including the design, the quality of the filter, and how well it fits the user's face.
The best anti-pollution masks can filter up to 95% of airborne particles down to 0.3 microns. For example, an N95 pollution mask blocks 95% of fine particles, while an N90 blocks 90%. Other common standards include KN95 and FFP2, which are equivalent to the N95 standard for particles down to 0.3 microns. These masks are highly effective in environments with a high risk of exposure to harmful airborne particles or infections, such as shared office spaces, classrooms, and public places.
However, it is important to note that the effectiveness of a mask also depends on its seal. A good seal ensures that the mask is suctioned to your face during inhalation, preventing particles from leaking in or out. The seal should be comfortable and made with high-quality fabric or silicone that allows the mask to fit the contour of your face.
While masks can provide protection against airborne particles and infections, there is limited data to demonstrate their health benefits in real-world conditions. For example, a French agency assessed the potential health benefits of wearing "anti-pollution" masks and found insufficient data to support their effectiveness for the general public. Additionally, most of the masks on the French market are designed to protect against particles in the air and not against gaseous substances.
Furthermore, the use of masks may provide a false sense of security, leading to behaviour that could result in overexposure to air pollutants. It is also important to consider that masks may not be effective for individuals with beards, as the hair can interfere with the seal.
Overall, while anti-pollution masks can provide some level of protection, their effectiveness depends on various factors, and there is limited data to support their health benefits in real-world conditions.

Health benefits of wearing masks
There are several health benefits to wearing masks, especially in a city like London, which has high levels of air pollution linked to heart disease, strokes, and lung cancer.
Firstly, masks can protect you from harmful pollutants and toxic particles in the air, such as dust, metal, skin, and clothing fibres, and car exhaust fumes. This is especially important for individuals with pre-existing health conditions, such as cystic fibrosis, or those with pollen or other allergies, as masks can help filter out allergens and irritants, reducing allergy symptoms.
Secondly, masks have been shown to be effective in slowing the spread of infectious illnesses, such as COVID-19. They act as a barrier, trapping respiratory droplets released through coughing, sneezing, or talking, and preventing them from reaching others. This is beneficial for both the wearer and those around them, as it reduces the likelihood of inhaling germs and becoming infected.
Additionally, masks can provide a level of protection against poor air quality, which can include pollutants such as carbon monoxide, nitrogen dioxide, and sulfur dioxide. This is particularly relevant in highly populated cities like London, where air pollution can have detrimental health effects.
It is worth noting that not all masks are created equal. Some commercially available masks may be less effective in filtering out small particles. However, masks such as the N95, KN95, and NIOSH-approved masks are recommended for their high filtration rates and strong protection against various particles and droplets.
While wearing a mask can provide health benefits, it should not be the only solution. It is crucial to combine mask-wearing with other preventive measures, such as social distancing, handwashing, and addressing the root causes of air pollution.

Comfort and ease of wearing masks
The comfort and ease of wearing anti-pollution masks are essential factors to consider when deciding whether to wear one in London.
There is a wide range of anti-pollution masks available in the market, offering various features and benefits. Some masks are designed for specific activities, such as urban sports or running, while others are more general-purpose. The price range is also quite varied, with basic masks starting from £6.95 and more advanced options costing up to £88.36.
When it comes to comfort, a good mask should have a secure seal that fits well on your face. A tight seal is critical for the mask's effectiveness, as it prevents particles from leaking in or out. Adjustable straps, wire strips, and malleable nose bridges are features that contribute to a comfortable and customisable fit. Additionally, some masks have valves that improve breathing and reduce fogging up of glasses, enhancing overall comfort.
The ease of use of a mask is another important consideration. Disposable masks are generally considered more convenient than reusable options, as they require less maintenance. The 3M 8511 N95 mask, for example, is widely recommended for its comfort, effectiveness, and ease of use. It has stretchy fabric straps and an exhalation valve, making it a popular choice for long-term wear.
While comfort and ease of use are essential, it is also worth noting that the effectiveness of masks can vary. Some sources question the ability of masks to filter out tiny particles, and the presence of beards can significantly reduce their effectiveness. Therefore, it is crucial to consider the specific mask's features, fit, and your individual needs when deciding whether to wear an anti-pollution mask in London.

Normalising the use of masks
The use of pollution masks has been a topic of discussion in London, especially when considering the city's high levels of air pollution. While some individuals choose to wear masks, particularly on the London Underground, others may feel hesitant due to concerns about their effectiveness and potential embarrassment. However, normalising the use of masks could bring about several benefits.
Firstly, masks can provide health advantages to individuals. The London Underground, with its high levels of air pollution, has been linked to an increased risk of heart disease, strokes, and lung cancer. By wearing masks, commuters can reduce their exposure to these health risks. Additionally, masks can help protect against contagious diseases, as highlighted by individuals like Natalie Goodchild, who wears a mask while travelling on the Tube and running.
Secondly, normalising mask-wearing can raise awareness about air quality issues. As Harry Cole, managing director of Respro, mentions, addressing poor air quality requires more than just individual efforts. It involves implementing measures such as reducing the number of cars in cities and restricting vehicle movement. By seeing more people wear masks, there could be increased pressure on authorities to take more substantial steps towards improving air quality.
Moreover, normalising mask-wearing can help remove the stigma associated with it. Some individuals feel uncomfortable or embarrassed about wearing masks in public due to potential stares or judgements from others. However, by making it a common practice, mask-wearing can become socially accepted, similar to wearing a coat or carrying a bag during a commute.
To achieve this normalisation, several factors need to be considered. Firstly, it is essential to address the concerns about the effectiveness of masks. While some sources question their ability to filter out tiny particles, others recommend specific types, such as the inexpensive 3M 9332, which can block 95% of particulates. Additionally, ensuring a proper fit and choosing masks with multiple valves can improve airflow and reduce condensation.
Lastly, making masks more accessible and affordable can encourage their use. Masks are available in various colours, patterns, shapes, and sizes, allowing individuals to choose options that suit their preferences and needs. By addressing effectiveness, accessibility, and social acceptance, we can move towards normalising mask-wearing and, consequently, improving the health and well-being of Londoners.

Alternatives to wearing masks
While masks can help protect against air pollution, they are not the only solution. Here are some alternatives to wearing masks to reduce exposure to air pollution in London:
Avoid Polluted Areas
Avoiding areas with high levels of air pollution can help reduce your exposure. For example, the London Underground is known for having dangerously high levels of air pollution due to the build-up of fine particles of dust, metal, skin, and clothing fibre in the tunnels. By opting for alternative modes of transportation or less polluted routes, you can reduce your exposure to these pollutants.
Adjust Your Commute
If possible, adjust your commute to minimise the time spent in busy zones or near major roads. This can help reduce your overall exposure to air pollutants, especially if combined with the use of masks during unavoidable exposure.
Indoor Air Cleaners
Since a significant portion of our time is spent indoors, investing in indoor air cleaners with particle- and gas-filtering capabilities can help protect against indoor air pollutants. This is especially beneficial if you live or work in an area with high levels of outdoor air pollution, as pollutants can still make their way indoors.
Congestion Charging and Bike Sharing
London has introduced congestion charging as a policy aimed at reducing urban air pollution. By utilising this system and opting for shared bikes or public transportation, you can contribute to and benefit from reduced air pollution levels.
Advocate for Policy Changes
While individual actions are important, addressing the root cause of air pollution is crucial. Advocate for and support policies that aim to improve air quality, such as implementing congestion charges, encouraging the use of electric vehicles, and regulating industrial emissions. By treating the cause rather than solely relying on masks as a solution, we can create more sustainable and long-lasting change.
