The size range for asbestos particles that I found was from 0.7 microns up to 90 microns, covid is quoted as about 0.1 microns..
I looked up a site selling asbestos masks, and you won't see anything like those useless blue things people are now wearing or those even more useless cloth masks.
Look at the specs of the masks they sell to protect against much bigger particles than covid, look at the prices of them.
All in all I would say that this renders your smart arze post pretty irrelevant, except as a good demonstration of the utter uselessness of the masks that people are being told that they must wear.
