Cabin air filter retro fit

[pwtr02ss]

I seen the other threads that people have done the retro fit on the 03-07 NBS and was curious if anyone had done it on a NNBS? I would like to put one in my avalanche because I have terrible allergies.

First of all I have NOT done this!!!
but others have from what I can tell and apparently the 04 and 08 have the same setup in the hvac unit except no door and added "ribs" inside. from what I understand you need to remove the initial hvac cover get two 02 filters, use a dremel and cut out the original door bottom dimensions, cram the two filters up there and then seal it up air tight (maybe with foil tape) - the guy who originally made the kits stopped for money reasons
I'll wait for others to chime in as I'm not going to start hacking under the dash just yet...

I did it on my 2010 Tahoe. It works great. Tony's links are what I used. It's a simple mod. I used my fein multitool for the cut. Just make sure you don't cut too far back. It should be a little wider than one filter. So you push one filter in and slide it back then slide the second filter in. Use cardboard from the box or a vinyl blind from a trashed shade to slide the second one in. The filters have a fabric on them that makes it hard to slide against each other.

I did it to get rid of the musty cabin smell. Use the Frame filter with the carbon in it - works great. I got flat stock aluminum at the Depot.

So it did clean up the smell of the interior? I get a musty smell from time to time.

Awesome. I had read the threads with others doing on 03-07 just hadn't seen it on any nnbs. Chrisalecia do you have any pics of yours? And thanks for info and links

It helped the musty smell a lot but didn't get rid of it totally. I want to get one of those cans on spray to clean it out. I also read someplace you can install a relay that makes the blower stay on for a t time after you turn the vehicle off to dry everything out.

What is the part number of the cabin filters we need? I think I am going to try this in my '13 Denali.

I didn't take a pictures but the 2 photos that Tony posted is exactly what mine looks like. I do remember seeing other photos online - if you search you may find them. It's an easy mod. It took me probably 2 hrs total and I took my time (measure twice cut once!!!!).

I'm glad I did it I think it has helped my allergies. Pollen is off the charts by me right now and the filters do make a difference.
