cabin filter

The cabin air filter is fairly easy to replace. By the time you get it out, there's no sense in trying to clean it. Replace it. You'd probably have to remove the glove box or some part of it to access the filter which is directly in front of the glove box, behind a cover held by some plastic tabs. Check the price of a filter at an auto parts store. Then make your decision, you could probably save a lot of money doing it yourself.

2007 Hyundai Sonata Limited >$30 in parts store. Open and empty out glovebox. Next, push in sides (near tabs) from outside glovebox in. Carefully pull plastic damper ring off pin (bottom right of glove tray exterior) and let the glovebox droop towards the floor. Pay mind to the ring attached to the damper piston, which is off to the right of the glovebox. In the place where the glovebox was, squeeze both tabs (2 sets) and gently pull out filter (don't be shy getting it started, but don't yank out too fast). Be careful as it may be very polluted with leaves and debris, so take care not to spill those materials back into the engine area. The new filter fits into the frame of the filter holder. You will need to carefully remove the old filter first, paying mind to little tabs. I had to fold in the filter to get it out. Carefully place the new one into the frame and reverse directions above. Use a flathead screwdriver (cover in electric tape) and use it to help put the damper ring back on the pin. Check the tabs on the sides of the glovebox to make sure they are tucked onto the sides.

Yes, you have one. Replace it. Your Owners Manual has detailed instructions with pictures in the Do It Yourself section (#6).
