Pollution Masks For Cyclists: Do They Work?

Cycling is a great way to get around, but it comes with the inevitable downside of exposure to air pollution. With thousands dying each year from poor air quality, it is important to consider the potential health risks of commuting through pollution. While cloth masks do not effectively keep pollutants out, anti-pollution cycling masks are designed to filter out harmful urban pollution and protect against respiratory issues. This article will explore whether these masks work and how they can improve the cycling experience for commuters.

The effectiveness of cycling pollution masks

Air pollution is a serious issue, with thousands dying annually from poor air quality. A study by Kings College London found that close to 9500 people die prematurely every year in London due to long-term exposure to air pollution. As such, it is important to consider the effectiveness of cycling pollution masks, which are designed to protect cyclists from the harmful effects of air pollution.

Cycling pollution masks are designed to filter out pollutants such as nitrogen dioxide, carbon monoxide, ozone, and particulate matter (PM). These pollutants are emitted by vehicles and can have negative health effects, including respiratory problems, reduced lung function, and an increased risk of developing asthma. While cloth masks may provide some protection, they are not as effective as specialised pollution masks, which are designed to securely fit the wearer's face and have filters that can block microscopic particles and noxious gases.

Specialised cycling pollution masks, such as those by Respro and Totobobo, are designed to fit securely and have filters that can block microscopic particles. The Totobobo mask, for example, is made from clear and flexible plastic and can be cut down to fit the exact size of the wearer's face. It features a white filter pad that makes it easy to monitor the particulates caught. However, it does not have an exhale valve, which can lead to moisture build-up during longer rides. The Respro mask, on the other hand, is marketed as "heavy-duty pollution protection" and features industrial-grade rubber and plastic construction, replaceable carbon filters, and dual "inhale ports" for easier breathing.

While these specialised masks offer better protection than cloth masks, they can still have drawbacks. Some users report struggling to breathe while wearing the masks, especially when riding at speed. The masks can also be uncomfortable, with some users experiencing sweating and marks on their faces. Additionally, the masks may not completely seal, allowing for air leakage, and they cannot filter out the very smallest particles, such as PM10s.

Despite these limitations, cycling pollution masks can provide a layer of protection for commuters, especially in heavily polluted areas. They can shield users from diesel fumes and provide protection during harsh winters. Public health organisations should consider encouraging the use of face masks as a strategy to mitigate the negative health effects of air pollution, especially in urban areas.

Drawbacks of cycling pollution masks

While cycling pollution masks do offer a layer of protection against harmful pollutants, there are several drawbacks to consider before making a purchase.

One of the main drawbacks of cycling pollution masks is the restriction of airflow, which can make breathing more difficult. This is a significant concern, especially for cyclists who are commuting at speed and require a steady supply of oxygen. The struggle to breathe can be frustrating and slow cyclists down, impacting their performance and overall experience.

Another drawback is the discomfort and inconvenience associated with wearing a mask. Some masks can feel restrictive and cause excessive sweating, which is not ideal for commuters. The tight straps and snug fit required for effective pollution filtration can also cause discomfort and leave marks on the face. Additionally, the pressure on the bridge of the nose from the tight straps can be uncomfortable and affect visibility, especially when wearing a helmet.

Some cycling pollution masks can also be bulky and aesthetically unappealing. The "Darth Vader on two wheels" look, as described by some cyclists, can draw unwanted attention and odd looks from pedestrians. This may deter cyclists from wearing the masks regularly, reducing their effectiveness in protecting against pollution.

Furthermore, the effectiveness of cycling pollution masks in filtering out ultra-fine particles has been questioned. While masks can protect against odours and larger pollutants, they may not be as efficient in filtering out diesel microparticles and other dangerous particles. This inefficiency could give users a false sense of security, as they may believe they are protected from all pollutants when they are not.

Lastly, the cost of purchasing specialised cycling pollution masks can be a drawback for some individuals. The more expensive masks tend to have better filtration systems, but this may not be accessible to everyone.

Different types of cycling pollution masks

When it comes to cycling pollution masks, there are a variety of options available, each with its own unique features and benefits. Here are some of the different types of cycling pollution masks that you may consider:

Respro Masks

Respro is a well-known brand in the UK for cycling pollution masks. Their masks, such as the Respro City mask and the Respro Ultralight Mask, are commonly seen among cyclists. The Ultralight Mask features N99-rated filtering technology and replaceable Hepa Sport 2.5 PM filters, blocking out pollutants, allergens, and bad smells. It is designed to be lightweight and comfortable, with a stretchy mesh-like fabric to prevent overheating. However, some users have noted that the mask can be pretty big and may cause skin chafing, especially on smaller faces.

Totobobo Masks

Totobobo offers a lightweight and reusable respiratory mask made from clear and flexible plastic. It can be easily customised to fit the exact size and shape of your face using a template. The transparent plastic avoids the "Darth Vader" look associated with some masks. Totobobo masks are effective at filtering out pollutants, as evident by the white filter pads turning grey or black after use. However, the full-face mask that covers the mouth and nose may collect moisture due to the lack of an exhale valve.

Vogmask

Vogmask is a popular brand in the US, offering colourful and patterned masks that stand out from the typical black wraparound face coverings. Their anti-pollution masks are N99-certified and have received approvals from various health organisations worldwide. Vogmask offers both single-valve and double-valve masks, with the double-valve option providing maximum airflow, comfort, and secure placement.

BioLogic Mask

The BioLogic mask is marketed as "heavy-duty pollution protection" for serious urban commuters. It is made from industrial-grade rubber and plastic, featuring two replaceable carbon filters and dual "inhale ports" for easier breathing during physical activity. While it provides effective filtration, some users may find it restrictive and sweaty due to the lack of valves.

Cambridge Mask

The Cambridge Mask, founded by a Cambridge University graduate, uses carbon cloth invented by the Ministry of Defence to protect against smells and particulates. It features an adjustable drawstring strap for a comfortable fit and comes in a range of bright colours and patterns.

When choosing a cycling pollution mask, it is essential to consider factors such as fit, comfort, filtration efficiency, and breathability. While masks can provide a layer of protection against pollutants, they may also restrict breathing and cause discomfort. Therefore, finding a mask that suits your individual needs and preferences is crucial.

How to choose a cycling pollution mask

When choosing a cycling pollution mask, there are several factors to consider to ensure you get an effective and comfortable mask.

Firstly, it is vital to select a mask that fits correctly and sits snugly on your face. Each mask will fit slightly differently, so consider the size and shape of your face when making your choice. Some masks, like the Cambridge Mask, offer adjustable drawstring straps to ensure a secure fit, while others can be customised by cutting them down to size, like the Totobobo mask.

The type of filter and valves included in the mask is another key consideration. Filters should be effective at blocking microscopic particles and noxious gases, with some masks offering HepA-type filters to screen out respirable dust and pollens. Valves are important for easier exhalation and releasing heat, water vapour, and carbon dioxide. The number of valves can vary, with most masks offering two, one on either side of the mouth.

The material of the mask is also important. While some masks are made from flexible materials like cloth or neoprene, others are made from industrial-grade rubber and plastic, like the BioLogic mask. Lighter masks may be more comfortable, but ensure they still offer effective filtration.

Finally, consider the look of the mask. Some masks, like the Totobobo, are made from transparent plastic to avoid the "Darth Vader" look, while others offer a range of colours and patterns, like the Cambridge Mask and Vogmask.

Overall, when choosing a cycling pollution mask, prioritise a secure and comfortable fit, effective filtration and valves, and a design that suits your preferences.

Alternative ways to avoid pollution when cycling

While pollution masks can offer a layer of protection against harmful pollutants, there are several other ways to avoid pollution when cycling. Here are some alternative approaches:

Choose Less Polluted Routes

When possible, opt for cycling routes that take you along back roads or quieter streets with lower traffic volume. This simple change can significantly reduce your exposure to vehicle emissions and heavy traffic, which are major sources of air pollution.

Time Your Rides Strategically

Try to cycle during off-peak hours when there is less traffic on the roads. This could mean adjusting your commute times to avoid cycling during rush hour, when the number of vehicles on the road is typically at its highest.

Maintain a Safe Distance from Vehicles

When cycling near vehicles, maintain as much distance as possible, especially when they are idling or accelerating. This helps to minimize your direct inhalation of exhaust fumes, which contain harmful pollutants and particulate matter.

Opt for Greener Transport Options

In addition to cycling, consider incorporating other sustainable transport options into your routine, such as walking. Walking for 30 minutes or cycling for 20 minutes on most days can reduce mortality risk by at least 10%. By leaving your car at home and embracing active travel, you not only improve your health but also contribute to reducing air pollution and mitigating climate change.

Advocate for Cycling-Friendly Policies

Support and advocate for policies that promote safe cycling and reduce air pollution. This includes measures such as implementing charging mechanisms to discourage excessive vehicle use, investing in cycling infrastructure, and redesigning urban spaces to prioritize active mobility and public transport. These systemic changes can have a significant impact on reducing air pollution and creating healthier, more sustainable cities.
