Filters 2.5

A PM2.5 filter is a disposable insert that improves a mask's filtration effectiveness, especially against the smallest aerosolized particles. A certified pm2.5 filter  used with a fitted cloth mask can block the vast majority of airborne particulates, including fine aerosols. When evaluating breathable, reusable solutions for everyday use, a pm2.5 filter + mask is one of the most protective options available.
