NIOSH

NIOSH is an acronym for The National Institute for Occupational Safety and Health. It is a federal agency in the United States tasked with collecting information and carrying out scientific research. Based on the research outcome, NIOSH makes recommendations regarding the prevention work-related injury, disability, illness and death.

A NIOSH N95 respirator is a disposable facepiece respirator that that covers the nose and mouth approved by NIOSH. The respirator is a particulate-filtering mask that meets the N95 air filtration classification of the U.S. National Institute for Occupational Safety and Health (NIOSH). An N95 respirator filters a minimum of 95% of airborne particles protecting the wearer from inhaling hazardous material.

The N in N95 stands for Not resistant to oil, unlike the P95, the N95 classification does not require a respirator to be resistant to oil. Masks can be used for up to three times provided they are decontaminated after every use session using UV light or vaporized hydrogen peroxide (VHP). N95 masks can be folded. The flat-fold respirator has a significantly greater protection rat.

An authentic NIOSH approved N95, will have the text marking “NIOSH” or it will have the NIOSH logo printed on it. The filter class, N95, a TC approval number following the format XXX-XXXX and it will have headbands not ear loops. The approval number on the mask must be documented on the NIOSH Trusted-Source page or the NIOSH Certified Equipment List (CEL).
