Bests & Worsts Reviews from Amazon

Buyer beware. The masks I received were in Powecom packaging but the masks inside were not Powecom's. They were fakes. Powecom masks have specific designations stamped on the mask. This proves authenticity, and classification certification. Important: According to OSHA (Occupational Safety and Health Administration) you should NOT buy a KN95 mask that does not have its GB2626-2006 or GB2626-2019 imprinted on it. Only KN95 with these designations stamped on the mask, have proven to filter almost as well as N95. If you get a mask with nothing stamped on the mask, return it, it's a fake.
