So this is likely a dumb idea, but if things got truly desperate I wonder if a snorkel mask would be a decent improvised protection. Your eyes and nose would be completely covered and your mouth is getting air from a direction/location that is unlikely to be in the "line of fire" from someone coughing or sneezing.

But if you have to breathe in infected air, doing so with your nose is far better than your mouth, since your nasal cavity has thicker membranes and a lot of mucus and hairs to catch particles, whereas through your mouth the particles are going straight into your lungs.

In fact, that effect might be so significant evolutionationary that it is the reason we have a seperate nose and mouth, rather than combining the two.

A nose lets you breathe while you eat.

Put a peg on your nose... You won't have any trouble eating after a few minutes practice. You just breathe between chewing.

The biggest problem is actually eating hot food - it seems the mouth can withstand hotter foods than the lungs, which get painful if you breathe in the steam from the half chewed food in your mouth.

Definitely. A snorkel/scuba mask is going to be better protection than most masks, though relatively expensive to produce and clean and can't be treated as disposable.
