Here's a REALLY simple exercise anyone can do right now, to demonstrate the basic value of face covering.
Put one hand over your mouth and the other in front of it about a foot away. Blow out of your mouth as hard as you can. You'll feel nothing on the hand not covering your mouth as the exhaust is suppressed and leaks slowly through your fingers. Now don't cover your mouth and do the same thing. You absolutely feel the exhaust.
There is no credible argument against face coverings reducing spread of what comes out of the mouth and nose. Sure if you are in close quarters with lots of people in the same room wearing masks, for an extended period of time, the particle and droplet build up will ensure inhaling them through most face coverings. But in fluid situations in the most common social interactions, it will be very difficult for enough infectious material to build up and actually cause infection if everyone wears a face covering.
