@hilltopsierra: Placement of an air filter in your workshop is critical. A common place is above the tools that make the most amount of dust. However, you should place your air filter on the longest wall, approximately 1/3 up on the wall and 12-24 inches away from the wall. This will create a circular air flow that will efficiently collect the dust. ##woodtok##airfilter##dustfilter##woodworkingtools##workshop
