I have severe OCD, so the pandemic has been especially difficult for my mental health. I did a boat load of research on masks before investing in a particular type, and I was so impressed with the independent studies on the Good Manner masks. I ordered them immediately and never turned back. I have been using them for a very long time now and feel 100 percent confident in them. They are comfortable, and they don't have an unpleasant odor like so many other masks that cause my allergies to flare up. I can wear lipstick without worrying about it getting smudged, and I can breathe freely, which is great since I'm asthmatic. I won't wear any other brand. I have been on several flights, to concerts, and various other events, and I would not have felt comfortable doing that if I didn't have so much faith in these masks!
