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.
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 All approvals for Wein Products (WPI) were rescinded in 2011.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 .
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 .
