What size is the Covid virus?
)
July 25th, 2020
I wonder how effective these masks I see people wearing really are.
Back in college, we were told to wear a respirator , not a paper or cloth mask, to keep from inhaling heavy metal particulates and silica.
In the studio, one could literally see airborne silica particulates floating in the air. especially with the lights dimmed and a flashlight.
If we could see this stuff in the air and needed to wear a respirator, how effective are cloth,paper, old underpants or whatever material people piece them together with, in keeping out a virus that is much smaller than clay particulates?
Using Fluther
