The 3M 53P71 comes assembled with P100 particulate filters that provide 99.97% filtration efficiency against airborne particles. These filters are the same P100 series used across 3M's half mask line. They protect against dust, mist, fumes, and fibers encountered in powder coating, painting, sanding, and grinding operations. Replacement filters are the 3M 2091 P100 cartridges available from Creative Coating Solutions.
