Bullshit! The CO2 passes out just as easily as you breath it in. Why are you such a dumbass? Never took chemistry in school?
asbestos is captured by a .3 micron mask, a virus is .0125 microns, no mask made will stop it except a full face gas mask. These cloth masks accomplish nothing except recycling your CO2 and limiting your oxygen.
I start cardiac rehab next week. Guess what is the first requirement before exercise? A mask!
