Somebody trying to tell me masks don’t work and they say they’ve seen studies blah blah . I’m pretty sure they’re wrong but what’s the best most convincing evidence to change somebody’s mind?

i think you meant um instead of nm for brownian motion also brownian motion isn't at play in flow, so it doesn't apply to the movement of particles through a filter. there is no electrostatic layer specified by the n95 standard, it's just a cheap way to get away with looser weaves and still pass the spec. there are no procedure masks that meet the n95 standard (idk what you mean by n95 surgical masks).
there are viruses that either form a spore or otherwise can float freely in air and due to some either bad reporting or scaremongering we had a few months back in '21 where people believed covid-19 was one of em. afaik its not but i didn't wanna make an already long post even longer and that's a bear to write on mobile.
i'm with you that masks slow down the process of getting infected with covid. this last few years have tested our literacy in a crazy way.
