Cheap Dust Collector
For general construction dust, this homemade rig can help to keep your job site clean.
I came up with an inexpensive dust filter that works for my shop as well as for the interior remodeling that I do.
I bought a 20-in. box fan, a piece of 1-1/4-in. vinyl-siding J-channel and a 20-in. by 20-in. furnace filter. As shown in the drawing, I attached the J-channel in a U-configuration on the intake side of the fan and slid in the filter. It works great. I usually buy the better particle filters and use my compressor to clean them out periodically.
