That's a real trove of information!

I see there are no cloth masks tested. I'd love to know how useful they are (or can be) as I much prefer being able to reuse my masks.

Edit: just realised that both Type and Style can be cloth and the cloth ones are presumably all under Style. All of them failed :(

Cloth is pretty useless... here's a neck gaiter compared to a surgical mask: https://www.youtube.com/watch?v=40gAXGOlEmI

Also tested my kids minion pillow case which beat the gaiter :) https://www.youtube.com/watch?v=EK_WryN-Y40

That's what I suspected... it would be instructive to include the cloth mask on the chart, just as a comparison to show the difference.

you can reuse n95s, nurses do it all the time. let them sit near a sunny window, off-smells will dissipate in a day. each mask is good for around 8 hours of continuous usage, but it's likely that the mask becomes too soiled before the electrostatic charge is neutralized.

In a non-healthcare setting the lifespan of an N95 is way longer than 8 hours perhaps 30-40.

Generally the idea is to get a new one when it becomes noticeably harder to breath.

Generally for COVID use, as opposed to say, construction, I find the mask will physically fail (e.g strap breaks or stretches too much, nose foam detaches) before the filter media is close to being used up.
