Full-face elastomeric respirators generally seal better. [2] For substances hazardous to the eyes, a respirator equipped with a full facepiece, helmet, or hood is recommended. [35] Eyeglasses can clash with elastomeric masks. Conventionally, full-face masks are modified, with prescription lenses inserted into the mask.
The shortages led to the U.S. government asking 3M to stop exporting US-made N95 respirator masks to Canada and to Latin American countries, [116] and President Donald Trump invoked the Defense Production Act to require 3M to prioritize orders from the federal government. [117]

An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.

] The corresponding face mask used in the European Union is the FFP2 respirator. [55] [56] Hard electret-filter masks like N95 and FFP masks must fit the face to provide full protection. Untrained users often get a reasonable fit, but fewer than one in four gets a perfect fit. Fit testing is thus standard, though debated.
