I wonder if you might be interested in a resuable cloth facemask that filters out fine particles?

It comes in plain black, plain green, plain burgundy, and lots of pretty, non-medical patterns like space invaders; Islamic geometric art; and florals.

It's not a complete solution, but it does help a medium amount. (I've been using it recently for wood smoke haze, which has been really bad lately.)
