There is no evidence that cloth masks are better at filtering out than they are at filtering in. They are not designed to be one way valves. They are pretty bad at both due to the massive amount of space between threads which virus droplets can just sail right through. No one should be wearing cloth masks if surgical masks are available and no one should be wearing surgical masks when N95 or equiv masks are available. This cannot be repeated enough. |
