I could have swore I read it on here but can't seem to find it searching, but did anyone see posted a how to on making your own filter out of a 3M home A/C filter? seems like I could get 4 filters out of one home filter if you cut them right but just wasn't sure which one would work. Yeah it's the cheap way out but the chepest i could find the filters online were around 10.50 Per. I just checked mine (2005 Civic) it's only got 42,000 miles on it and they are pretty full of junk. I tapped out most of the bigger stuff but they are still pretty yucked up.

Anyhow just wondering if anyone knows where the how to is. Thanks in advance.
