||This leaflet summarizes the main points of NIOSH policy for respiratory protection against exposures to airborne crystalline silica. NIOSH recommends the use of half-facepiece particulate respirators with N95 or better filters for exposures to airborne crystalline silica at concentrations less than or equal to 0.5mg/m3. The Occupational Safety and Health Administration (OSHA) also specifies the use of at least a 95-rated filter efficiency. The recommendation for a 95-rated filter efficiency reflects the improved filter efficiency of N95 filters over the earlier dust and mist filters.
