Dr. Huayue KN95 Filtration Masks are effective at filtering PM 2.5 particles that could be harmful to inhale. These KN95 masks help keep you from breathing in pollen, soot, asbestos, mold, metal particles, and bacteria and virus particles. If you live or work in an area that contains potentially harmful airborne material, a protective face mask is a must. Dr. Huayue face masks are made with two layers of melt-blown fabric and three layers of woven fabric.
