AF N95 respirators are respiratory protective devices designed to achieve a very close facial fit and very efficient filtration of airborne particles. Note that the edges of the respirator are designed to form a seal around the nose and mouth.

N95 respirators and surgical masks are examples of personal protective equipment that are used to protect the wearer from airborne particles and from liquid contaminating the face. The Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH), and the Occupational Safety and Health Administration (OSHA) also regulate N95 respirators. AF N95 respirators are NIOSH approved.
