Does this work? My spouse recently purchased some 3M N-95 masks directly from 3M’s Amazon store. They’re supposed to arrive in a box that has a code on it which you can enter into 3M’s website to verify it’s real and not a counterfeit. Instead they arrived in a clear plastic bag with no printing on it. There’s no code so I can only assume they’re either fakes or were pull from a larger box (which means potentially handled inappropriately). Given my spouse’s immune condition, that’s not a chance we really want to take so we’re going to throw them out.
