3M 8710IN Mask (Pack of 5)

The 3M is a dust 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 3m mask is used as a disposable face mask for respiratory protection against fine dust particles.
