An N95 respirator is a disposable filtering facepiece respirator or reusable elastomeric respirator filter that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84, effective July 10, 1995.
A World War I British P Helmet, c. 1915 Zelinsky–Kummant protivogaz, designed in 1915, was one of the first modern-type full-head protection gas masks with a detachable filter and eyelet glasses, shown here worn by U.S. Army soldier (USAWC photo) Indian muleteers and mule wearing gas masks, France, February 21, 1940 A Polish SzM-41M KF gas mask, used from the 1950s through to the 1980s
half-mask, from below the eyes to below the chin; fullface mask, from above the eyes to below the chin; Some elastomeric masks include one-way valves to let exhaled air out unfiltered. This reduces the resistance when the user is breathing out, and some find it makes the mask more comfortable. [2] It may also reduce inwards leakage. [10]
The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. [1] Nasal cannula and simple face masks are described as low flow delivery systems. [2] [3] Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.
