Identifying Counterfeit and Fake N95 Masks

/

Approximately 10 million fake 3M N95 masks have been distributed in at least five states, and federal, and state authorities are managing to seize and cease the counterfeit ring. The masks are designed to mimic 3M N95 masks, with details including raised marking and printed logos. As a response, 3M has issued a warning describing the model and lot numbers to look out for when purchasing masks. 

The National Institute of Occupational Safety and Health (NIOSH) has also released a guide on how to spot masks that are falsely claimed to be approved by the NIOSH. NIOSH-approved masks will have an official approval label on or within the packaging, and the filtering facepiece respirator (FFR) of the N95 masks should also have an abbreviated approval. 

The NIOSH Certified Equipment List (CEL) or the NIOSH Trusted-Source page can be used as a resource to verify and determine whether NIOSH has approved the respirator. The approved FFRs include N95, N99, N100, R95, R99, R100, P95, P99, and P100.  

Signs that a respirator may be counterfeit:

• No markings at all on the filtering facepiece respirator (FFR).

• No approval (TC) number on FFR or headband.

• No NIOSH markings.

• NIOSH spelled incorrectly.

• Presence of decorative fabric or other decorative add-ons (e.g., sequins).

• Claims of approval for children (NIOSH does not approve any type of respiratory protection for children).

• FFR has ear loops instead of headbands.

NIOSH also offers additional tips on how to identify counterfeit masks, including third-party marketplaces. Some things to consider include: 

• If a listing claims to be “legitimate” and “genuine,” it likely is not.

• Examine transactions history and feedback if possible

• Look for fluctuations of items traded over time (high or low transaction periods)

• Look for price deviations and fluctuations (Is it too good to be true?)

• Look at the quantity a buyer has in stock.

  • During a time of shortage, advertising “unlimited stock” could indicate that the respirator is not approved.

• Does the seller break marketplace policy and hide their contact information within images to circumvent filters.
