There is quite a large range of pollution masks on the market. Many have been proven to filter out more than 80% of PM2.5 particles. However, many masks simply block large dust particles or the sun.
There are many different types of masks. For a daily commuter, the most important things to look for include: the size, fit, and seal on their face, as well as the filtration rates printed on the packaging or info slips, backed up by certification agencies.
Next, the mask should be adjustable so that it can be made looser or tighter to fit the individual. Although many brands don’t allow a person to test before they buy, it is important to try a mask on to see if it is comfortable, and if there is a good seal. Brands like AryMask allow customers to try the mask on before they buy in order to make sure there is a full seal.
As a more active outdoors person, a pollution mask that is stretchy and adjustable, that stays on the face as you move is the best choice. For someone who uses a mask to commute by motorbike, elasticity is less of an issue. If a person is outside for more than an hour a day, and the air pollution levels are over 100 PM2.5, they should protect themselves with a pollution mask. If they walk around polluted areas with lots of vehicles, or If they use a bicycle, they will be breathing in about 7 times more air than if sitting on a motorbike.
In the hot weather, it is important that a user can wear a mask even when it’s extremely hot. Only a few models of masks are made from mesh materials, while other materials such as neoprene tend to be very hot. For a humid climate, it’s best to use a light colored mask that will let the air flow around the filter.
