A BREATH OF FRESH AIR
Here's a portable air filtration unit you can build at home.
SHOP OWNER: Chuck Lenz
LOCATION: Bismarck, ND
I had a used furnace blower sitting around that I removed from the old furnace we replaced a couple years ago. This past winter I decided it was a good time to work on making a portable air filtration unit. Portability would make it useful in the shop or for any possible remodeling jobs in the future.
For the frame of the unit, I used angle iron that I bolted together much like you would find in any tool stand. The front and back panels are 3/8-inch Masonite that I later painted. It uses two 1" X 16" X 20" furnace filters; one on each side of the blower. It weighs in at 86 pounds but is easily moved by the locking casters I used.
The blower has four speeds and is controlled with an electronic timer switch. For the top, I decided to use ¾ -inch solid surface material.
