For optimum protection against airborne particles, we offer a 5-layer PM2.5 filter made of activated carbon and non-woven melt-blown filter cloth.
PM2.5 filters are made from the same advanced materials used for respirators like the N95 and KN95, in addition to activated carbon fabric. The non-woven top layer blocks large particles, while the melt-blown cotton mid-layer catches and absorbs dust and stray particles, and activated carbon traps particulates via a process called adsorption, and serves as an antibacterial. When used as intended, the replaceable filter inside the Filter+ face mask provides 7 layers of protection for maximum filtration against dust, dander, pollen, and microscopic air contaminants.
Maintenance & Care
Filters should be replaced once a week if using the face mask regularly. Filters are not machine washable.
