How do I know if my N95 mask is genuine?

The labeling on a mask is key to identifying NIOSH-approved N95 masks. A NIOSH approved N95 mask will have the NIOSH approval number (beginning with “TC” and following by the NIOSH number) printed on the front of the mask along with lot and model numbers. You can verify that your mask is NIOSH approved by checking this NIOSH website.

NIOSH does allow private labeling of N95 mask packaging. Therefore, an approved N95 mask may be in packaging that reflect a different “manufacturer” than the actual manufacturer of the mask. In these cases, the actual manufacturer’s TC-number and identity needs to be detailed on the packaging and on the printing on the mask.

When NIOSH becomes aware of counterfeit respirators or those misrepresenting NIOSH approval on the market, these respirators are posted on the Counterfeit Respirators / Misrepresentation of NIOSH-Approval webpage to alert users, purchasers, and manufacturers.
