Our premium PM 2.5 filters will ensure maximum protection when wearing your mask. This 5 layer design can effectively reduce the number of germs, pollution, allergens, and dust in the air you breathe. 

This technology protects against particulate matter 2.5, the smallest and most dangerous form of airborne particulates, which are 40 times smaller than the size of a human hair. 

We recommend changing your PM 2.5 filter after 3 days of usage to ensure maximum protection.
