If you have more time than money you can build one. Be aware that diy dust control requires some effort to produce a good system. Oneida Air will design a system for you I believe. Their stuff is not cheap but works better than anything else I tried. I have about $2000 in my system currently but will be adding to it shortly.

(snip) In regard to human health, I once had a conversation with one of the   maintenance guys who asked if we could reduce the moisture   requirement during the the winter.  On some of the coldest days the   water pumped into the building to keep the humidity at 40% made the   filters damp.  There was a concern about mold in the filters.   I   always wondered how effective the filters were because it was always   difficult to keep dust off the pianos.  Then I realized I probably   was the biggest contributer to the problem in that my shop generated   saw dust that was probably circulated around the building.  I never   purchased a saw dust control system/filter for my shop but probably   should have. I looked at some filtering units that hang from the   ceiling, but never got farther than looking.  Does anyone have   suggestions that Paul might consider both for the health of the   building and for a healthy shop environment? (big snip) Hey Richard, My suggestion is full dust control- dust collector, air filter, personal protection. I have an Oneida 2 hp commercial dust collector, a Delta air filter and a Trend Air Shield and life is much better in my shop. DP Dale E. Probst, RPT Ward & Probst, Inc.
