Take a look at the 3M 8511 N95 (eBay has some great deals on them)

I wear one every single day in the shop except when spraying, then I wear a respirator with a charcoal filter.

Hope this helps!

I have been getting horrid headaches after using my sander. Being from the
old school of thought, a respirator was what was used for painting, solvents
etc... Is there a respirator out there that won't fog my glasses or be an
absolute pain in the face to wear? I am not thrilled about the thought in
the first place but it is better the the pain I get after a couple of hours
of sanding. Any thoughts or comments???
