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
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?
