What's an N95 respirator?
An N95 respirator is a respiratory protective device 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. Surgical N95 Respirators are commonly used in healthcare settings and are a subset of N95 Filtering Facepiece Respirators (FFRs), often referred to as N95s.
What does NIOSH N95 classification of air filtration mean?
It filters out at least 95% of airborne particles including large and small particles.
N95 is an abbreviated name for an N95 filtering facepiece respirator, which is the most common particulate-filtering facepiece respirator. N95-rated filtering facepiece respirators have a filtration efficiency of at least 95% against airborne (non-oily) particles when tested using the NIOSH criteria.
How do I know a respirator is an authentic N95 NIOSH approved respirator?
An authentic N95 respirator is marked with the text "NIOSH" or the NIOSH logo, the filter class ("N95"), a "TC" approval number of the form XXX-XXXX, the approval number must be listed on the NIOSH Certified Equipment List (CEL) or the NIOSH Trusted-Source page, and it must have headbands instead of ear loops.
