• Description:
  This infographic describes the filter classes of respirators classified by the National Institute for Occupational Safety and Health (NIOSH). NIOSH classifies the filtering media in respirators based on its resistance to oil and its particle filtering efficiency. The resistance to oil is designated as “N” [Not Resistant to Oil], “R” [Somewhat Resistant to Oil], or “P” [Strongly Resistant to Oil/Oil Proof]. Particle filtering efficiency is designated “95”, “99”, or “99.97” [percentage of airborne particles filtered]. [Description translation provided by software, please excuse errors.]
