Good mask helps only so much. You must also wear it properly.

Cheap surgical mask is just as good as N95 respirator if you don't wear them properly. It much seal around your skin. For example, if you don't trim your beard so that mask touches skin all around, better mask does not help.

In fact, increased humidity under the mask may be one of the main reasons why wearing mask protects their user.

Was funny today at the post office this old guy took his mask off, cleared both nostrils like blowing with his fingers and put his mask back on like wtf... Oh well. Then he touches the pad that you pay with oh man...
