An N95 respirator is a commonly-used, abbreviated name for an N95 filtering facepiece respirator,[1] which is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration, meaning that it filters at least 95% of airborne particles. This standard does not require that the respirator be resistant to oil; another standard, P95, adds that requirement. The N95 type is the most common particulate-filtering facepiece respirator.[2] It is an example of a mechanical filter respirator, which provides protection against particulates but not against gases or vapors.
