Air pollution consists of a variety of harmful airborne particulates like soot, smoke, gases, chemical vapor, and residue. The primary sources are vehicle emissions and industrial processes.
The most commonly used equipment to combat air pollution is an anti pollution mask.
However, you shouldn’t assume that an anti-pollution mask will filter out all harmful pollutants. None of the standard pollution masks on the market were effective against pollution gases such as the nitrogen dioxide emitted from vehicle exhaust or cigarette smoke. There are many types of respirators on the market. You need to be clear about how and when you intend to use your mask.
Masks made and sold for a particular job in the workplace are different. They must meet rigorous standards and usually are very efficient. These controls and regulations do not apply too much cheaper masks intended for general use by the consumer.
The purpose of an anti-pollution mask is to filter out harmful particulates in the ambient air. Following multiple tests, it seems that the tightness of the fit is crucial. Facial hair prevents a good seal, and the fit also depends on the shape of the wearer’s face. Then again, if the fit or seal is too tight, then breathing through a mask is not easy, and wearing a mask can, therefore, pose problems for people who have breathing difficulties or heart problems. The advice to these wearers is to wear a mask for short periods and only when you feel it is essential.
Research shows that exposure to air pollution can have negative impacts on our lungs and heart. The latest estimate that outdoor air pollution causes 4.6 million deaths each year.
Experimental studies in China
In two of the studies carried out in China, where facemasks are very popular when wearing an N95 facemask while walking in the center of Beijing, blood pressure was lower than when not wearing a facemask. In the participants with heart disease, blood flow, and oxygen delivery to the heart was seen to be better when wearing the N95 facemask. In another study in Shanghai, healthy participants also had lower blood pressure when earing a facemask. These studies suggest that wearing a particle-filtering mask can reduce the short-term exposure effects on the heart and blood vessels of exposure to urban air pollution.
How efficient are anti-pollution masks
Cheap masks can prove quite useful to filter out fine particles in a polluted city atmosphere but no so good at filtering out vehicle exhaust emissions. Common sense would lead you to buy a more expensive mask to filter out most modern-day pollutants.
Several factors can limit efficiency:
- The type of filter
- The use of a valve
- Leaks between the filters and the mask
- Leaks between the mask and the face
- A good or bad fit on the wearer’s face
- Quality of filter
Cloth masks are only marginally effective in protecting against harmful pollutants. Studies have shown that they only remove between 15% and 57% of particles emitted from diesel engines. They also give a false sense of security, allowing the wearer to go out in dense pollution even they are poorly protected.
Masks with filters such as the N95 only work well when worn correctly, which is often not the case.
Of course, the best solution is not to use masks at all but to reduce pollution, but this could be a long way off.
Problems with multiple uses
Anti-pollution mask wearers have reported several issues during recent years. These include:
- Heating of the breathing air
- Shortness of breath
- Breathing difficulties
- Condensation inside the mask
- Unforeseen costs of replacement of masks or filters
The N95 is generally accepted to be the most effective. It is a more advanced version of the inexpensive cloth masks. However, they are either not available or too expensive in many places where pollution is most severe. Made of paper – not washable and reused like cheap cloth face masks.
Regarding the problem with poor fitting, which reduces the effectiveness of a facemask, solved it with a mask that can be customized to fit any face, young or old.
Reusability also offsets the cost.
There are substantial health benefits to wearing an anti-pollution mask, but the pollution mask must fit well, be customizable, and be reusable.
