I was putting an amplifier and sub last night and decided that while I had my dash apart I would go ahead and pop out my cabin air filter like I've read about on here and clean it.
...This ISN'T a washable filter as mentioned on the various write-ups. I feel as if I would know this- I'm an HVAC Service tech! It's a throw-away, and it supposed to be replaced with another of the same part number.
Considering that my truck is only about a year old and I don't smoke, I was pretty surprised to see how dirty this filter actually was. I would recommend, that if you plan to CLEAN it instead of replace it, use compressed air- not water!
What I decided to do is call the company that produces a lot of our custom-sized filter applications and ordered a replacement as a FARR 30/30, the industry's leading pleated filter. I ordered several of them- I'm going to pop one in my truck and see how it goes, show you guys some pictures and see if anyone would like to order a few- they'll only be a few dollars a piece and are FAR superior quality than these cheap factory ones-
...Granted, I'm not replacing this with a washable filter, but a high quality filter in an application like this will not need to be replaced very often at all, I would say YEARLY- and this one would certainly be worth more to blow out and put back in than the shotty one that comes with your truck.
Let me know what you guys think, and I'll post some pictures of the product when my order comes in.
