Low-Cost Filter Cleans Shop Air
When Noah Hubbard picked up some surplus wall cabinets, he had a brainstorm that he could use one to pull dust from his shop/garage.
  “When I parked my car in the shop, it would get covered with a film of dust,” recalls Hubbard. “Some of it was probably ash from the wood burning stove. Now I can park it in there for days, and it stays clean.”
  Hubbard cut out the back side of a cabinet. He then framed the front and back so each would accept two 16 by 25-in. furnace filters. At one end, he installed a small squirrel cage fan. The 1/20 hp motor can run steady for hours, pulling shop air through the filters.
  “It pulls a lot of air through,” says Hubbard. “I angle the discharge on it at the ceiling to help circulate air.”
  Hubbard says he changes the filters with the seasons.
