The white cheap nuisance dust masks did virtually nothing for me in stopping dust. I developed very serious breathing and sinus problems.
I always use P2 rated masks. I'm in Australia so I don't know if you USA guys have the same ratings. The P2 masks have a little filter/valve thingy at the front. They are disposable, but not single use. They will work until the elastic straps break(quite a while), then throw out.
If you can get a bandsaw blade with HSS tips they will last much longer on exotic hardwoods. Carbide tips are even better, but they usually are only suitable for large bandsaws, and are very expensive(worth the long term investment though).
