Still tics me off that the wk2 recirc button will not stay on! This is my first car where I could not turn recirc on and have it stay on forever. Apparently jeep thinks it knows what is best for us and is removing our freedom of choice.

Maybe Jeep should run for Congress!

Turn off Auto mode. Pretty simple, Jeep isn't telling you how to run your life. By turning on auto mode you told it to make the decisions for you.

My XK and my Subaru do the same thing when in auto mode.

Unfortunately that's not correct. Active carbon filters (CHARCOAL) will NOT last 2 to 3 Years. They will however last 3 to 6 months. The ability for the filter to absorb smells is defined by how much particulate fume and odors are absorbed,as well as how much dust and dirt is sucked up. The more smelly shit you drive through the shorter it will last. The more dusty conditions you drive through the shorter it will last. You should change your cabin air filter no less than twice a year with ideal changes being 4 times a year. Plugged filters due to a lack of maintenance is the number 1 cause of poorly performing HVAC systems. Not only will performance degrade but you will exponentially shorting the life of the blower motor as well as the ac compressor. People are going to say Im full of shit about the compressor, but its true. A plugged air filter causes a reduction of air flow which cause evaporator temps to plummet due to low suction temps. This in turn does not allow all of the liquid refrigerant to be atomized when passed through the metering device, thus bringing liquid back to the compressor. We all know what happens when you try to compress a liquid. If you don't know then go poor a gallon of water down your intake while your car is running. Just kidding don't do that. My point

CHANGE YOUR FILTERS PEOPLE.

Re: Cabin Air Filter Woes

Since Jroll is too modest and too much of a gentleman to do so here, I will:

JRoll's Uber-Tech Cabin Filter for WK2

I'll be doing a rinse of my UT Custom Filter end of February and will post update. So far thumbs up.

Tip: Another effective way to avoid diesel fumes in the main cabin is drive faster than everyone else.

That also helps prevent rock chips.

Thanks for the detailed explaination. I was basing my statement on the fact that I changed the carbon filters in my BMW 540i every 2-3 years and they worked just fine (although there were 2 filters in that car)

After I test these filters I ordered for a few days, I will let those that were interested, know if they work better than the paper-only filters.

I'M going to guess that there was a pleated air filter up stream of the charcoal filters in your BMW, and that contributed too their longevity. By the way how much did you pay with shipping?

Re: Cabin Air Filter Woes

No pleated air filter upstream, just a well thought out design. The air comes up from the bottom of the filter, so much of the dirt falls into the bottom of the filter box, and the filter itself is thicker; also more expensive, about $75 to replace each filter. It also has a rubber gasket around the outside.

Shipping on the new filters I order was free, but since I am in Texas and so is the supplier I had to pay 7% Sales Tax.

Re: Cabin Air Filter Woes

I've had the "auto" mode on my BMW's and Lexus's in the past, and while they work to certian degree, I think the overall design is to far from ideal to matter much to me. I've found that "smelly air" isn't considered contaminated air, as the sensors are set to mostly detect NOX fumes. So, if your stuck behind a garbage truck, the auto system will keep switching the dang air flow to fresh, even after you switch it to recirc. You have to turn the whole auto mode off, then hit recirc. So, if I have to go through all that, then what good did all that "engineering" do?
And a free tip for those who want to go the activated charcoal route, don't use air fresheners and fragrance sprays in your vehicle. I don't use them anyway, but if you take it to car washes and the like they do and you might not think of it, but the activated charcoal will just clog itself up removing what you just paid to spray in the air......then you have to replace the filter again....sort of working against yourself here. Mercedes has a stock activated charcoal filter as well in the ML. Those worked great. We might try seeing if the size in the WK2 is a MB stock size for some other model seeing as how these two models share some parts???
