Homeland Securities Investigations (HSI) and 3M have identified counterfeit products bearing the following Lot Codes. The Lot Code may be found on individual masks and the boxes in which they were shipped. Note that there may be counterfeit N95 respirators with Lot Codes not listed here.
Even though these are counterfeit lot numbers; they are pulled from ‘real lot numbers’. AHRMM suggests that if an organization finds one of the lot numbers they contact 3M directly to review the specifications and the N95 respirator for validity.
