I finished this air cleaner back in November 2011 and have enjoyed using it for the last 3 months. The basic design came from a book/magazine called The Complete Small Shop that was put out by the same people who publish Shop Notes. I had to modify the size to accommodate the squirrel cage blower (~$25) that I was able to find along with easily available filter sizes.
It holds three 20×20 furnace filters: 2 before the fan and 1 after the fan. The filters are held in place with oak frames and the bottom panel slides back and forth to provide access.
I was a little nervous about the wiring, but the pull switch was pretty easy to install and the guy at Home Depot was actually pretty helpful. He gave me enough information to get it all done.
Awhile ago I picked up some dark blue paint from the reject shelf at Walmart that matches the current shade of blue used by my alma mater, Brigham Young University. Since I was in the mood, I taped up the lid and sides to add the “Y” and stripes with white spray paint. I pretty pleased with how it turned out.
It is mounted to the joists in the ceiling above my shop and secured with turnbuckles and eye hooks.
It was a fun project and makes a noticible difference in the dust level in the rest of the garage.
