Homemade air filter

Brent has been having some trouble with his allergies lately, so I rigged up a homemade air filter thingy to clean up the air a little.

Basically I took a box fan and duct taped a heater vent filter (the anti allergy kind) to the back of it. When the air gets sucked into the fan, it has to go through the filter first. I got the idea from some allergy website - hopefully it helps.

The box fan I borrowed from my parents, so it was free, and the filter was $15 at the hardware store.
