I believe these are Authentic, High Quality Respirators
Reviewed in the United States on August 3, 2020
1) The Anit-Counterfeit label was vetted via the Guanzhou Powercom Chinese website, and was found to be authentic. I have developed products with anti-Counterfeit labels, and this label looked authentic and was similar to others I have used in the past. I made up a dozen random numbers and none came up as authentic except for the one on the package label.
2) I also cut one of the 10 masks up, and it is in fact constructed they way they describe with the right number of layers, the right number and type of melting attachment points, and the right type of fabric / material at each layer.
3) And it is on the FDA list, and is not on the FDA removed list.
So for the above 3 reasons, I have high confidence that this is an authentic KN95 Respirator. (I'm no professional...)
