I was worried about buying counterfeit (ineffective) KN95 masks so I researched this manufacturer once the masks arrived and they were listed on the FDA and CDC government websites.
These are very comfortable and work great by themselves or with a second cloth mask over top. I like that they stay in place so there no need for constant adjusting. These are also comfortable to breath in because they don’t cling to your nose and mouth.
