Setting up shop, I wanted something that would filter dust from the air. This is of course a supplement to a face mask and dust collector. As many others have done, I started with an old furnace fan and motor. I just built a box from 3/4” Birch plywood, made a Douglas Fir frame for the far to sit on and enclosed it all. I installed a switch and cord for convenience. Initially I had three filters in series but that proved to be far too restrictive and I was getting very poor air flow. Also, the whole unit ended up being just a huge “in the way” box that was hard to move around. I reworked the filters so there are now three filters in parallel and I put some wheels and adjustable feet on the box, installed a top and a cleat system so it will now serve as a work table and outfeed support for the table saw.
