I have a large Powermatic dust collector in its own air tight room with ductwork running to all my shop tools. The air pressure from that room is vented through a 2 foot square box filter back into the shop. The result is a very fine dust that is re-introduced to the shop that I'd like to contain. I've thought about hanging a sheet or piece of plastic in front of the filter but would like to do a better job of capturing that dust. Has anyone else dealt with this issue?
Thanks,
Robin
