Even cloth filters out 70% of respiratory virus particles. The notion that only a properly fitted N95 mask is effective is ridiculous and is probably costing lives.

This. Also, nobody ever talks about double masking. You know, if you've got no N95, then put on two surgical masks (each facing the other way). If you don't have surgical marks, wear two cloth masks and wash them with antiseptic solution daily.
Sure, but if you inhale 30% of that from your hand into your mouth, and exhale 30% to your hand, it loses more than just not touching your face.
