So covid droplets can pass through the mask on one side, and not pass through the other side?
The mask is there to block your orifices from pumping out covid particles, especially the big ones. The small ones are still passing. But the guy with no mask on is still bombarding you with all his particles and you're absorbing a lot of them.
You don't wear your mask on your entire face. Your eyes are still absorbing that stuffs.
That's why the mask needs to be used by everyone in a closed environment.
