Even so, you should check that your N95 mask is of commercial quality, that it bears the NIOSH approval mark, and that it fits your face comfortably and securely. There are a variety of N95 masks available, but all of them provide at least 95% filtration against airborne particles and are NIOSH-approved. The N95 protective mask, which is sometimes referred to as a N95 respirator, should not be confused with KN95 masks, which have the similar designation but are held to different standards. KN95 masks were designed to provide a level of protection superior to that of a N95 respirator, which is administered by the Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health (NIOSH).
