Do you guys ever use a recirculating air cleaner? Not something that you would probably use while actually sanding as it does increase air currents but it is great when cleaning up or doing things where a little bit if air movement is not a big problem.
Woodworkers often have these in their shops to improve air quality and I made mine out of an old furnace fan and motor with a series of filters - the last one being a micropore filter.
It makes a hell of a difference when sanding wood work.

My dad has something similar he made in the shop. He uses furnace filters and fans to suck the dust and fumes out.
