Sometimes casually referred to as an “N95 mask,” this PPE is worn on providers’ faces, forming a tight seal around the nose and mouth. Though it looks like a surgical mask, an N95 is actually a respirator that filters out at least 95% of particles in the air. What’s more, it requires a 20-minute “fit test” to ensure proper fitting—and it does not provide adequate protection for people with facial hair. The CDC does not recommend N95 respirators for public use.
