Product Description

Pure-Msk's nanofiber physically blocks these particles with impossibly small nanofiber pores. As illustrated, pollen is **0x larger than the pores, ultrafine dust is more than *0x larger and cigarette smoke is more than 3x larger so the filter effectively blocks these particles. Filters greater than *5% of particle matter including: aerosolized particles, bacteria, allergens, mold, pollutants, fire, dust, cigarette smoke and fumes. Offers a very high air permeability due to vonsistent pore size which results in a very high ratio of pores to surface area.
