I ordered these to replace the ones that I was using for work that made me unable to breathe. These ones do not touch my nose or mouth which is super helpful because I can talk to my customers even though I have a mask on. Unlike cloth masks that allow your breath to go through the cloth, I tried to blow away some dust with my mask on and was unable to but with the exhale ports I can still exhale without risking my germs getting on someone in front of me when I cough or sneeze. I would say number one covd19 mask!
