This 3ply face mask composed of three layers of filters. The outermost layer filters out the largest dust particles, the innermost layer preserves the respirator’s shape and the middle layer is composed of electrostatic filter media. It has the ability of this respirator mask to filter above 90% of 0.3-micron particulate dusts. (Scientific research has proven thatfor all dust particles sizes, 0.3 micron dust are the most difficult to filter effectively).This mask is used as a disposable face mask for respiratory protection against fine dust particles. It is a bestselling Safety mask in 3m Safety products line. elastic band for comfortable fitting on every face is not a mask and it is not a breathing mask used in acid/alkaline/gas particles.
