Air Pollution Masks: A Recent History Of Respiratory Protection

The use of air pollution masks has become increasingly common in recent years, particularly in countries with high levels of air pollution such as China and India. While the practice of wearing masks to protect against air pollution may have originated in these countries, it has since spread to other parts of the world, including the United States and Europe. The COVID-19 pandemic has also played a role in normalizing the wearing of masks, with many people now wearing masks to protect themselves and others from the virus. However, the effectiveness of masks in reducing the absorption of ultra-fine particles has been debated, with some experts claiming that they are more useful for protecting against odours than harmful particles. Nonetheless, as air pollution continues to worsen in many parts of the world, it is likely that the use of air pollution masks will become even more prevalent in the future.

Air pollution masks in Beijing

The use of air pollution masks has become increasingly common in Beijing, China, due to the city's poor air quality and high levels of pollution. Beijing's air quality is often ranked above 150 on the Air Quality Index (AQI), with extremely smoggy days reaching up to ten times the safe levels recommended by the World Health Organization (WHO).

The Chinese government has faced mounting pressure to address the issue, and while some efforts have been made to improve air quality, the problem persists. In 2015, authorities in Beijing took 2.5 million cars off the roads in preparation for the China Victory Day Parade, resulting in clear skies and an AQI of 17 for two weeks. However, this was a temporary measure, and the city's air pollution soon returned.

The use of pollution masks has become a daily necessity for many Beijing residents. One resident, Chen, shared that wearing a pollution mask has become as routine as wearing glasses when going outdoors. Similarly, Wang Wei, a street vendor in Beijing, considers his mask essential to working outdoors, as he experienced coughing fits and breathing difficulties without it.

The effectiveness of commercially available masks in protecting against air pollution has been called into question. A study examining the penetration of diesel exhaust particles through dust half-masks found that many masks may not provide adequate protection due to a poor facial fit. This highlights the need for improved mask design and evidence-based guidance for consumers.

While the war on pollution has shown some progress, with a 33% average fall in PM2.5 concentrations across 74 cities, Beijing's air pollution remains a significant concern. The reduction in PM2.5 concentrations was largely due to a shift from coal to gas for energy, but experts warn that coal will continue to be a major energy source for China in the coming years. As a result, residents of Beijing continue to rely on pollution masks as a daily accessory to protect themselves from the harmful effects of air pollution.

Effectiveness of masks in reducing ultra-fine particles

The use of face masks to protect against air pollution has been a topic of discussion and debate. While some people argue that masks can provide a level of protection against pollutants, there is also evidence that suggests their effectiveness in reducing ultra-fine particles may be limited.

The masks worn by the US Olympic cyclist team at the 2008 Beijing Games, for example, could not prove the efficiency of mouth masks in reducing the absorption of ultra-fine particles. Gilles Faravel of the mask production company Res-Pro stated that anti-pollution masks "protect more from odours than from diesel microparticles." This sentiment is echoed by Luc Goffinet, director of the GRACQ cyclists' association, who believes that the focus should be on improving air quality rather than relying solely on masks as a solution.

The effectiveness of masks in reducing ultra-fine particles may depend on the type of mask and the context in which it is used. For example, reusable fabric masks are not designed to block ultra-fine particles like a higher-grade medical respirator mask. However, they can still provide some level of protection by capturing larger respiratory droplets and aerosols. Similarly, while face masks may not completely sterilize incoming air, they can reduce the risk of transferring viruses to your hands and other surfaces.

The quality of the filter and the number of layers in a mask can also impact its effectiveness. Masks with multiple layers have been found to be much more effective at filtering particles, but they can also make it more difficult to breathe. The electrostatic charge on the fibres of a mask can boost its performance, but this charge may degrade over time. Additionally, the fit of the mask is important, as improving the face seal can enhance the performance of cloth masks.

In certain countries, such as Japan, wearing surgical masks is a common practice, especially during winter or when experiencing allergies. In Western countries, however, wearing masks outside of medical settings was less common before the COVID-19 pandemic. The pandemic has led to an increase in the variety of face coverings available, including FFP2 masks, which can be safely decontaminated by heating them in an oven or boiling them.

Air pollution masks as a fashion statement

Face masks have been used to protect against air pollution for many years, particularly in East Asian countries such as China, Japan, and India, where air pollution is a serious problem. In Western countries, however, the wearing of masks to protect against air pollution is a more recent phenomenon, and it has sparked some debate. While some people argue that masks can help protect against certain allergens, pollutants, and unpleasant odours, others claim that they are ineffective against the most dangerous particles and can even make it harder to breathe.

Despite this debate, air pollution masks have started to become a fashion statement in recent years. As the problem of air pollution has become more pressing, with cities like Beijing, Tehran, and New Delhi experiencing dangerous levels of air pollution, the demand for face masks has grown. This has led to the emergence of luxury or "luxe" masks that appear on catwalks at fashion weeks in Beijing and Paris. Chinese designer Wang Zhijun, for example, made headlines for upcycling old Adidas Yeezy Boosts, designed by Kanye West, into masks. Vogmask, a respiratory mask company, has also partnered with designers for Hong Kong and Paris Fashion Weeks, successfully incorporating masks into high fashion contexts.

The fashion industry has recognised the potential for masks to be more than just a protective measure against air pollution, but also a way to make a statement. In the same way that white bandanas have been used to protest Trump and safety pins to declare an alignment with minorities, neon camo masks can raise awareness of air pollution and its impact on human health and ecosystems. As Wendover Brown of Vogmask stated, masks can be "a tool that addresses the challenge now while raising consciousness of the issues".

While some may view the fashionability of air pollution masks as a positive development, encouraging more people to wear masks and raising awareness of air pollution, others may see it as trivialising a serious issue. Regardless of the varying opinions, it is clear that air pollution masks are becoming increasingly mainstream, with more and more people turning to them as a way to protect themselves against harmful pollutants in the air.

Political divide surrounding mask-wearing

The use of face masks to protect against air pollution has been a topic of debate for some time, with early examples of masks being used to protect against air pollution including the US Olympic cycling team at the 2008 Beijing Games. However, the COVID-19 pandemic brought about a new dimension to the discussion, with masks being recommended to slow the spread of the virus. This development led to a notable political divide surrounding mask-wearing, particularly in the United States.

In the US, the issue of mask-wearing became highly politicized during the COVID-19 pandemic, with a sharp divide emerging between those who supported and opposed mask mandates. While nearly all public health experts agreed that masks were an effective tool to curb the spread of the virus, especially in crowded places, some Americans viewed mask requirements as an infringement on their personal freedoms. This resistance to mask-wearing was exacerbated by the stance of former President Trump and his supporters, who often refused to wear masks in public and associated mask-wearing with anti-Trump sentiment.

Polls conducted during the pandemic revealed a stark partisan divide in mask-wearing behaviour, with 98% of Democrats reporting wearing masks in public compared to only 66% of Republicans and 85% of Independents. This divide was further influenced by conflicting actions and statements from government officials, such as the refusal of Texas Governor Greg Abbott to fine residents who refused to wear masks, despite recommendations from public health officials.

The politicization of mask-wearing extended beyond partisan lines, with some individuals and groups protesting mask mandates on the basis of personal freedom and government overreach. In Montgomery, Alabama, for example, the City Council initially voted down a face mask requirement despite testimony from medical professionals about the surge in COVID hospitalizations. Additionally, the effectiveness of masks in curbing the spread of the virus was questioned, with some claiming that masks were useless against COVID-19 and even detrimental to health, contributing to respiratory issues and cognitive decline.

The political divide over mask-wearing also intersected with other social and cultural issues. For instance, New York's push to restrict masks during pro-Palestinian demonstrations divided Democrats, with civil rights advocates and Black lawmakers expressing concerns about race-based enforcement and hostile conditions for protesters. Furthermore, mask-wearing became associated with anti-Trump sentiment, further complicating the political landscape surrounding the issue.

Air pollution masks for cyclists

The use of air pollution masks has become increasingly common, especially in light of the COVID-19 pandemic. While the practice of wearing masks to protect against air pollution may be relatively new to some cultures, it has been a common practice in countries like Japan, where masks are worn as a courtesy by people with coughs to prevent the spread of their illness.

For cyclists, the question of whether to wear an air pollution mask is a topic of debate. On the one hand, cyclists are more exposed to air pollution and absorb more fine dust particles than people in cars, making them more susceptible to respiratory and cardiovascular risks. Belgian Science Policy's 2011 findings support this, showing that people on bikes absorb four to nine times more fine dust particles than those in vehicles.

To counteract these risks, some cyclists opt to wear air pollution masks made of activated charcoal or electrostatic filters, which protect against certain allergens, pollutants, and unpleasant odours. However, there are conflicting opinions on the effectiveness of these masks in reducing the absorption of ultra-fine particles. While masks can provide a sense of protection, they may also restrict airflow and make breathing more difficult, especially during strenuous activities like cycling.

Despite the uncertainty, the market for anti-pollution masks for cyclists is growing. Companies like Respro, Totobobo, BioLogic, Cambridge Masks, and Vogmask offer a range of mask options for cyclists. These masks often feature adjustable straps, sub-micron filters, and dual "inhale ports" to improve comfort and breathability while filtering out pollutants.

When considering wearing an air pollution mask while cycling, it is essential to prioritize proper fit and comfort to ensure adequate protection and breathability. Additionally, exploring alternative cycling routes along back roads or dedicated bike lanes can help reduce exposure to air pollutants.
