In the summer of 1995, the National Institute for Occupational Safety and Health (NIOSH) published new public health regulations and upgraded test requirements for the certification of particulate filters. Nine classes of filters were defined - three series (N, R and P) and three efficiencies (95, 99 and 99.97%).
P100 particulate respirators are oil-proof (suitable for use in environments where oil aerosols may be present) and 99.97% efficient. When a hazard requires the use of a respirator with HEPA filtration, the appropriate class is Type 100 (N100, R100, or P100) P100).
