A disposable particulate respirator—also known as an “air-purifying respirator” because it protects by filtering particles out of the air as the wearer breathes—is a personal protective device that is worn on the face, covers the nose and mouth, and is used to reduce the wearer’s risk of inhaling hazardous airborne particles. These respirators are designed to be worn once and thrown away. Disposable respirators are NIOSH-rated for particulate protection and do not protect against gas or vapors. Respirators that filter out at least 95% of airborne particles are given a 95 rating. Those that filter out at least 99% receive a “99” rating. And those that filter at least 99.97% (essentially 100%) receive a “100” rating. NIOSH-approved disposable respirators are marked with the manufacturer’s name, the part number, the protection provided by the filter (N95, N99, N100), and “NIOSH.” If a disposable respirator does not have these markings, it has not been certified by NIOSH.
