In my horn shop, I found that a LOT of dust was created with my belt sander (2 x 72). That was the major source of problems, although the wood lathe did generate a lot of wood on the floor.
I built a containment box around the sanding belt and hooked it up to the shop vac, which worked really good, but I found I had to clean the filter at lease daily, if not more often. I then hooked up a little Cyclone between the vac and the sander and life is really good. About once a month, I clean the filter as part of monthly maintenance and dump the junk out of the Cyclone tank. That's it. Personally, I think it is a lot better than any other dust control that I have used.
In my shop in Idaho, I had two sheds placed about 4' apart, the shed on the left was the "clean" shed and the one on the right was where I did all the sanding. I built a manifold system between the two shed and had a 750 cfm fan drawing dust out of various areas of the shops. Then I also had a Shopsmith dust collector in the sanding room hooked up to the belt sanders. It was ducted to the dust collection system and vented outside as well. I think the shop vac with the Cyclone worked better than that. No doubt.
