The masks are to stop the FLUID from leaving your lungs, not all gas.
The virus lives in the fluids and come out when you cough, sneeze, etc.
If it stopped all gases, you wouldn't be able to breath.
EDIT: I wear a mask STRICTLY because I saw Trump wearing one, you fucks do whatever you think is clever, im sure each and every one of you is a nobel winning scientist, if its all the same to you, im just gonna go with the POTUS, good luck.
