The Durasafe DS130 is a dust mask composed of three layers of filters. The outermost layer filters out the largest dust particles, the innermost layer preserves the respirators shape and the middle layer is composed of electrostatic filter media. It has the ability of this respirator mask to filter above 90 percent 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.
