Cabin Air Filter aftermarket for 2000 Impreza RS?

I have a 2003 Forester and they charge about $40 for those too. But I also wanted better air filtration than the standard filters because the air quality here in the Washington D.C. Metro area gets pretty nasty in the summer.

Anyhow, I made my own three-phase electrostatic filter from scratch. It works *really* well--maybe too well; it actually took out the "new car" smell. :-)

As a side benefit, it is a 'permanent' filter -- it is *designed* to be washed and reused. That is, a person only buys one per car, ever.

If you tell me the dimensions of the Impreza filter and send me a picture of the thing I could make one for you.
