Thanks for the tip. I just did a little research on masks and ordered a 3M N100 mask with the exhaust vent as a travel emergency item. Hopefully I don't have to use it, but will be glad I have it if the need arises. I think I can flat-pack it in my carryon without too much of a penalty on space.
Also, I'm not too worried about my eyes as I can sleep quite readily on any flight. Eyes shut= should be good. Right?
