User Notice – Notices are provided to inform users of a condition or risk that may exist with a NIOSH-approved respirator.
NIOSH has reviewed and concurs with the facts in the user notice as of the date indicated on the NIOSH website.
Disclaimer: Links to non-Federal organizations do not constitute an endorsement of these organizations, their products, or programs by NIOSH and none should be inferred. NIOSH is not responsible for the content of the individual organization web pages found at these links. They are provided solely as a service to our users. A NIOSH certificate of approval is not an endorsement of the respirator by NIOSH. Such endorsements are not to be stated or implied by manufacturers in advertisements or other publicity. NIOSH certification represents that the equipment has met the requirements of Title 42, Code of Federal Regulations (CFR) Part 84.
With all rescissions, the approval number is no longer listed in the Certified Equipment List (CEL), or on any of the NIOSH web pages that list approved respirators.

When NIOSH becomes aware of counterfeit respirators or those misrepresenting NIOSH approval on the market, we will post them here to alert users, purchasers, and manufacturers.
April 28, 2017 – Counterfeit Respirators or Misrepresentation of NIOSH Approval
Figure 1 is an example of a counterfeit N95 Respirator that was brought to NIOSH’s attention. While the TC number and private label holder are valid, this unapproved unit can be identified by the misspelling of NIOSH on the front of the respirator.
Figures 2 and 3 are examples of counterfeit respirators. These respirators are being sold as if they are NIOSH-approved even though the manufacturer, Zubi-Ola, is not listed as a NIOSH approval holder or a private label holder.
Figure 4 is an example of misrepresentation of the NIOSH-approval. All approvals for Wein Products (WPI) were rescinded in 2011. However, the manufacturer’s website continues to state the ViraMask N99ESC is certified by NIOSH. View the user notice announcing the rescission.
Figure 5 is an example of a counterfeit respirator. The NT-V2 Nano Bi-Directional respirator is being advertised as if it is NIOSH-approved, including a NIOSH approval number. While the TC number (TC 84A-0427) is valid, it does not belong to Pasture Pharma. Instead, TC 84A-0427, is an approval number for a 3M full facepiece respirator with cartridges.
Figure 6 is an example of a counterfeit respirator. Pacifico Salud SAC is selling units using the Suzhou Sanical Protection (SSP) approval number (TC-84A-6766) and label without SSP’s permission. Additionally, there are two errors on the respirator package. The first error is that they claim the N95 respirator is 96% efficient. The second error is located in the bottom right corner of the package where is states the respirator is manufactured by Benehal China, who is not a NIOSH approval holder. (1/4/2019)
Check the respirator approval markings (graphic below) or the Certified Equipment List to verify your respirator is NIOSH-approved. Additional information is available on the NIOSH Trusted Source page.
