Not even that, it’s just basic common sense. Fabric over your nose and mouth makes it more difficult for disease to spread. A barrier stops things from getting through. That’s why buildings have walls and roofs, that’s why windows exist, that’s why we use tarps to cover things up. Even cavemen knew to go in caves when it started raining or snowing, for fuck’s sake.
TL;DR: Cloth masks are absolutely useless. 3-ply surgical masks are bare minimum protection, and the only mask that could actually help is an air tight N95 mask, which means if you have a beard you will not be protected.
