Hm, I think I changed my mind, Microcovid gives me 630 microcovids wearing the sealed P3/P100, and 1,600 microcovids with the sealed N95. (It’s guessing at 3.5% prevalence near me, which is really high.)
Also I wore the P3 for a few more hours and it’s mostly fine, except around the ears.
A possibly-useful semi test for fit with N95s and the like is sharp inhalation and exhalation, observing whether the mask sucks in and puffs out.
Also, if you wear glasses then I think a well-fitting mask shouldn’t steam them up.
And yes, I was told being reasonably clean-shaven is important for a good fit.
Thanks, v helpful. I now plan to use N95 plus tape for the planes.

The 1⁄6 for planes seems way too high.
When I count microcovids for airplanes, I assume people are silent. That makes a big difference.
Good point.
