Watch out, it is a “I saw it on the Internet, it must be true” kinda site: a quick search shows “SOTT” is highly suspect...the research author the website quoted has no paper related to masks/respirators at the the quoted site “Researchgate.net”. And at least one of the research papers quoted near the bottom says nothing about “masks vs. no mask” but refers to “N95” masks vs. surgical masks. Enough for me to ignore. Buyer beware.

One study quoted as “proof” (not!):

One of the research papers mentioned on the site “sorta” supports their position: https://www.cambridge.org/core/journals/epidemiology-and-infection/article/face-masks-to-prevent-transmission-of-influenza-virus-a-systematic-review/64D368496EBDE0AFCC6639CCC9D8BC05

I don't understand the point of your comment.

All three of the articles cited in your post pretty clearly conclude that both surgical masks and N95 respirators fail to protect from virus infection.

Did you even read them?

Both of y'all might find my post 124 above to have some useful information.

It didn't get into the mask vs no-mask, unless you count filtration efficiency of 0% to be equivalent to no-mask, which it basically is. BUT, the big thing that applies to most people these days is the gap/no-gap difference. NO ONE wears a properly sealed mask, which drops their filtration efficiency from ~95% down to 30-40%. So yes, masks do help some (basic physics tells us this), but not very much, and likely not enough to prevent infection vs no mask. And the negatives of wearing masks constantly, I think, definitely outweigh the little benefits.

Irrelevant to the medical/physics of it, I personally HATE breathing in warm, damp, exhaled air, I've never even been able to lie face-to-face with a girlfriend for more than a minute. Or wear a mouth/nose-covering face mask for winter weather.
