This is a very quick, easy task that can be done without any tools. Changing the cabin air filter will help remove the musty odor you get from using the A/C. You will see in the picture below that the filter can get very dirty/clogged in a short amount of time. When the filter traps all the leaves/bugs/debris, it traps all the musty smell too.

Kia recommends you change your cabin air filter at/around every 12-12,500 miles.

What you will need:

- Cabin air filter
- An empty glove box

Start with opening your glove box:

That's one dirty filter !

Thanks Munky!
An alternate method to squeezing in the sides of the glovebox (step #3), is to remove the pins by twisting them out with your fingers or small pliers. This is what the manual says to do.

IDEA for everyone (I did this on my S2k) ... LOL, when I replaced my cabin filter I also put a couple of dryer sheets in there too and it smells like clean fabric softener every time I used my AC LOLOLOL...

Also, home depot sells these little gel looking cards that you stock onto AC filters for the house that have like 5 different smells (Ocean breeze, Forrest, Etc...) they just adhere to the filter in your AC in your house, no reason why you cant use them on your car filter too,...

But the dryer sheets worked for a really long time... I got the idea once using a tube of toilet paper stuffed with these in them while I smoked in my car so I didnt have a lingering smell lolol

LOL I used to use the toilet paper tubes with dryer sheets when I was younger. We called them "buttholes" we had to use them when we smoked in my friends basement. And im not talking about tobacco... :Squint:

Yeah on the step to push in the sides, really the best route is the simple twisting of the 2 side latches and be ready it is ready to drop straight down on the hinge. Such an easy job and SOOOO much easier than our VW to change out for sure.

Here is mine at around 18k miles (IIRC)

Plus one on the carbon cabin filter, just as long as it doesn't smell.

Hey Munky, or anyone that may know...


My GF has a 2011 Forte SX. It's getting close to needing the cabin filter replaced. Do you think the process is almost similar?

It could be, as the process is the came on the current Sportage as well

Thanks. I'll try it out when we get the new filter.

I'm not the DIY'er type, but have to admit this was the easiest cabin air filter replacement ever! No screwdrivers, no fuss. Thanks for the tips, Munky! I used the following carbon infused filter I got from ebay: 2011 - 2012 Kia Optima CARBON Cabin Air Filter - Fits OEM# 3SF79-AQ000 F784EB9AA | eBay. I highly recommend it as the quality seemed a step above the Kia filter I took out (after 9500 miles) and the part came the day after I bought it. Not always the usual ebay experience...

Just read the post about how bad the filter was at 20k... couldn't believe it til I pulled mine out. I have 18k, tho I live in SFL, so the ac is always going.. thought they were good for about 40k. Btw... I pulled it out just to look, and when I saw how bad it was I thew it out.. is it bad to run it a few days without a replacement?
