N95 pollution masks are popularly used as a preventive measure against air pollution

Pollution masks are considered to be an effective way for protecting yourself from ill effects of air pollution. Research has shown that even minor exposure to air pollution can have negative impact on lungs, heart and even the brain. Many people opt for wearing pollution masks which claim to reduce ill effects of air pollution or the severity of it. There are a variety of pollution masks, ranging from simple paper dust masks to the ones which supply clean air and prevent exposure to minute particles in the air. N95 masks are the most commonly used masks – the ones which come somewhere between the aforementioned extremes.

How do pollution masks work?

The ability of face masks to reduce ill effects of air pollution depends on the type of pollutants, the kind of mask you are using and how the mask is used. Pollution masks are usually assigned a protection factor, which indicates the percentage of pollutants that the mask does not remove. A protection factor of 5 means that all but 5% of pollutants are filtered out by the mask. This is given the fact that the mask fits tightly on your face.
