Our FilterTech® liner is molded to connect into the outer mask and offers 5 layers of material while still being highly breathable:
Outside Non Woven Layer. Outside filter wrapping that offers a base level of filtration
Non Latex Cotton - Provides an initial barrier of 50% filtration
1st Electro Charged Meltblown Polypropylene Layer - Filters larger PM10, pollen and other allergens
2nd Electro Charged Meltblown Polypropylene Layer - Filters smaller PM2.5, dust and bacteria
Inner Non Woven Layer - Inside filter wrapping that offers a base level of filtration
Our filters come in two sizes (XS/S and M/L) for maximum filtration coverage and the best possible fit across our range of mask sizes.
