P95
P95 has multiple meanings depending on the context. In occupational safety, P95 refers to a class of particulate-filtering respirators approved by the National Institute for Occupational Safety and Health (NIOSH). The letter P indicates oil-proof filtration, while the number 95 signifies a minimum filtration efficiency of 95% for airborne particles. P95 respirators are designed to provide protection against both oil-based and non-oil-based aerosols and are commonly used in industries such as painting, woodworking, metalworking, and chemical processing. They are available in various designs, including tight-fitting models and loose-fitting hoods, and may require user seal checks; tight-fitting models typically require fit testing. The performance of P95 respirators can depend on particle size, circulation, and the presence of oil aerosols, with P-series offering more oil resistance than N-series but generally less than P100.
In statistics, P95 refers to the 95th percentile of a dataset: the value below which 95% of
Other uses of the term P95 are context-dependent and may refer to product names or project designations.
