I ordered this product on 9/1 due to the comments saying they were labeled KN95 and they were! I was very happy, so I ordered another box on 9/8 for a family member on chemo. They arrived with slightly different packaging and no longer the KN95 designation. They now come stamped with FLTR95. When looking over the product qualification certificates I noticed the following changes in Primary Product Materials: - KN95 labeled: Melt-Blown Polypropylene Filter 42.8%, Hot Air Cotton 28.6%, Polyester Shell 28.6% - FLTR95 labeled: Polyester Shell 50%, Hot Air Cotton 16.7%, Melt-Blown Polypropylene Filter 33.3% There is an obvious change in materials that likely change the mask''s filtering properties. If you''re looking for KN95, this product is NOT for you.
