I have a Ikea bamboo tray that has been sitting on my porch (away from the rain) - it also molded up after a month or two. I think it might have something like raw linseed oil as a finish.

My personal version of this is keep your fingernails where you can see them - works especially with big machines like jointers. On dust extraction, at least Mirka has mesh-style sanding pads (Abranet) that are great at allowing dust removal. I think Bosch also sells similar stuff now. If circulating air inside the shop, you could run it through an indoor air purifier. These machines are sold for pollen allergies, but basically they are just blowers with A/C filter panels in them. Should be easy to DIY such a box. If you are working with paint or other substances with strong odors, get a proper spray painting mask. "A" in the filter code indicates protection against solvent vapors, "P" is particulates, higher number the better, so A1P3 is basic vapor protection with high dust protection, for example. These are not too expensive, 50 bucks should get you a good mask with removable filters.
