OSHA Issues New FAQ on Use of N95 Respirators Against Coronavirus

Washington, D.C. – On October 19, OSHA issued a new frequently asked question (FAQ) on “how N95 respirators effectively protect wearers from coronavirus exposure. The FAQ was issued in response to incorrect claims that the respirators do not adequately protect individuals from the virus.


OSHA explains that the masks use a combination of factors, including mechanical filtration and electrostatic charge, to ensure virus particles do not pass through to the wearer. “The N95 respirator filter, as is true for other NIOSH-approved respirators, is very effective at protecting people from the virus causing COVID-19. However, it is important for employers and workers to remember that the respirator only provides the expected protection when used correctly.”
