Passenger compartment filter

[TrueBlue]

First off, I love my truck. Plenty of power, looks great, and so far no issues that a lot of people have experienced.

 

That said, I have noticed that of all my new vehicles this one seems to have the least effective cabin filter of any of them, and there have been many, from Subarus, Toyotas, and yes Chevy's. Anyone notice this? The smell of other vehicles exhaust gets to the point where I'm not even sure there's a filter installed. I haven't checked it yet, thought I'd try this instead. Assuming it is there, and not still wrapped in celophane, has anyone heard of or found an aftermarket filter that does better at keeping outside odors at bay. Of course I'm talking about when the button is pushed to recirculate the cabin air.

GM has a carbon cabin filter available. I forget the number off the top of my head. It works well on road kill skunks.

Thank you!

I think I've read somewhere before that the recirc feature doesn't seal off all of the air from the outside. In other words it still draws in a little fresh air. I don't think a better filter is going to help much.

We'll see. Mine is due to arrive Saturday. Any improvement would be welcome though.

It will help for sure!

Received the filter, it was a perfect fit size-wise. Haven't driven the truck yet but given that it was twice the weight of the stock filter as well as being much more substantial in apparent filtration material I have no doubt it's going to be a big improvement. The stock filter was little more than pleated paper. Might have blocked dust but I don't see how it could filter any odors or even pollen.

Thank you for the tip!

A normal paper filter won't do anything to capture smells, just pollen and similar particles. You need to switch to a carbon filter.

Well, I did That's what this thread is about. Haven't driven the truck since I did the swap but I have little doubt it will block out other vehicles' exhaust smell much better now.
