The 3M 9004IN 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 80% of 0.3-micron particulate dusts. Scientific research has proven that for 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. 3M 9004IN mask comes with aluminium nose clip and neoprene elastic band for comfortable fitting on every face.
