Two Companies Voluntarily Rescind NIOSH Approvals for Certain N95s

NIOSH announced that it has honored the requests of the companies Innonix Technologies Limited and United States Mask LLC to voluntarily rescind some of their respirator approvals. This means that as of Sept. 18, one United States Mask respirator, the N95 Model 1812, is no longer approved by NIOSH and may no longer be used, manufactured, assembled, sold, or distributed. The voluntary recission also affects two of Innonix Technologies’ approvals for N95 filtering facepiece respirators with an effective date of Sept. 19. Respirator users and others are encouraged to review the notices related to Innonix Technologies and United States Mask for further details as well as information regarding the affected approval numbers.

NIOSH’s certified equipment list can be used to confirm testing and certification approval numbers, which are printed on NIOSH-approved respirators. The website of the agency’s National Personal Protective Technology Laboratory provides a list of additional guidance documents intended to inform users of respiratory protective devices.
