Box contains 20 Masks
This protective mask effectively filters non-oily particles to serve as a barrier to potential air pollutants that can be harmful. The face mask’s filtration efficiency of five layers will help block out PM2.5 air pollutants like allergens, virus, bacteria, dust, droplets, and other harmful non-oil-based particles in the air, at least up to 95 percent.
It also features an adjustable nose wire to provide proper and comfortable fit to the face contour. Ideal for those at higher risk due to age or pre-existing conditions as well as those in high contact situations like custodial staff and nurses
