Filtering out dumb mask ideas.

====================

So I'm picturing an N95 mask with the exhalation valve(s) pointing downward or off to the side(s), and instead of venting into room air those valves direct exhaled air into a fine-mesh exhalation bag, whose surface area is perhaps several times that of the mask, but not so large as to be in any way cumbersome. Since the wearer is no longer forcing exhaled air out through a relatively small mesh area, that should make for easy exhalation. Thoughts?

Admittedly, a ski mask is better than nothing when it comes to protect yourself; but there is nothing like an ABC mask when it comes to protect others, or not?

Surgical mask; loose fit, considerable leakage, protects against sizable droplets, splash/spit. N95: tight fit, seals, very broad particle range effectiveness including 95% or better against virus-sized particles. https://upload.wikimedia.org/wikiped...espirators.pdf

I heard about a factory that had its workers wearing spray socks because masks were in such short supply.
