They do make masks that can significantly filter an airborne virus out of the air you breathe, but they aren't cloth, and they have to be fitted tightly to your face so air cannot leak in and out around the sides of the mask. >Studies that have been done show that if an individual might get infected within 15 minutes in a room, by time and concentration of the virus in the room, add a face cloth covering you only get about five more minutes of protection. On the other hand if you use the n95 respirators and fit them tight to your face, you can actually spend 25 hours in that same room and still be protected. https://www.pbs.org/wnet/amanpour-and-company/video/do-masks-provide-much-protection-we-think-bglhwy/ https://www.pbs.org/wnet/amanpour-and-company/video/do-masks...
