Got a nebulizer in the mail today and ran this procedure. Both N95 (3M Aura 9205+) KN95 (Powecom, earloops) failed. This was not surprising because of my beard. What was surprising was that the N95 failed worse than the KN95. I’ll try again with a much shorter beard soon-ish. __philipn__/1523517311415513090

Perhaps I shouldn’t be so surprised since my understanding is that KN95 is harder to breathe _through_ but is more forgiving of leaks around, whereas N95 is easier to breathe through but has less tolerance for the seal.
