FAQ

What is NIOSH?

In the U.S., respirators are tested and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH). NIOSH tests and certifies respirators based on their physical and performance characteristics, including filtration efficiency.

What does NIOSH approved mean?

NIOSH approval is issued only to a specific and complete respirator assembly after the respirator has been evaluated in the laboratory and found to comply with all of the requirements of Title 42, Code of Federal Regulations , Part 84, and after the manufacturer's quality plan is determined to be satisfactory. It also means, CDC approved.

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.
