I watched Dr. Judy Mikovits on the Brandon Howse show Wednesday night on LindellTV and she said the masks do the opposite of working. They actually HELP the virus - the air you breath out is higher moisture from building up behind the mask - the warmer air - so the virus has a better carrier of water vapor droplets than if you just didn’t wear a mask and breathed into open air. Makes perfect sense - virus needs a carrier. Just think of the mold in a damp room.
I agree with that statement for the majority of masks.
