PHILADELPHIA - The CDC says about 60 percent of the KN95 masks that they evaluated over the last two years were counterfeit and not working the way they are supposed to.
The good news is the CDC did compile a list of the counterfeit masks they came across and put it on their website with pictures and explanations.
One major thing to look out for is that N95 masks should be Niosh approved. If it doesn't list that or it's misspelled, the CDC say it's fake.
On the other hand, KN95 masks are not Niosh approved so if you see the Niosh marking on a KN95 mask then it's fake. These masks are also all business so the CDC says if they have sequins or a decorative fabric and they're marketed as a N95 or KN95 mask then they are not legitimate.
