Poster's comments:

1) I have used bandanas as a breathing filter during hard times in Kuwait when having to breathe sooty oil contaminated air. The air would sometimes get so dark that you could not see your own hand at 1400 during the afternoon.

2)  When blowing tarry black boogers out of our nostrils, bandanas worked well for that purpose, too.

3) They can be used for do-rags, too.  ( http://en.wikipedia.org/wiki/Do-rag )
