So now that I'm cutting and shaping/sanding G10, I'm thinking maybe I need to go beyond the basic white mask. I try to do all my heavy-duty flattening, thicknessing, and grinding on dangerous materials on a flat-bed grinder set up on a work-bench in the side door of my shop. I open the double barn doors, put a fan on high blowing out, and spray the belt with water to keep down the dust. I also vacum and sweep out after each of these sessions. Still, you can't be too careful. I'm also thinking of shaping some more wedges from malachite, and I just got in some beautiful red japser for the same purpose. Dangerous stuff from my reading of the lapidary boards!

There are a million choices on Amazon and Ebay; what do you guys recommend that will filter out that dangerous dust? I might even consider full-face to take care of eye protection too. Thanks in advance for any thoughts!
