>Why didn't they test N95 masks? The difference between a cloth mask and an n95 mask when dealing with an airborne virus has been tested. >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...
