@jbf1755 the 3M Aura I’ve gotten with the foam nosebridge doesn’t conform well to my chin - I have a rounder face. I like the duckbill kind with a larger breathing chamber to make it easier to breathe - Gerson 3230 duckbill is what I got. My 18 year old with a full beard found the Harley N95 L188 worked well for him as a more vertically oriented mask. The aura is pretty gappy at his beard and hard to conform around his small nose.
