2009 Mazda 5 - We've owned this one since 2013, and I hadn't ever changed the cabin air filter. I don't know whether it had been changed previously. Anyway, it's a bit of a pain, but worthwhile - the old 2-piece filter was almost clogged with dried leaves, and the air box had a lot of leaf debris in it. I won't go into a detailed explanation; there are a lot of good YouTube how-to videos out there. But I will say that lots of contortions were required. The opening is too small to accommodate a 1-piece filter, so the top half has to be inserted first and then pushed up to allow the interlocking bottom half to be slid in. It was a pain the first time, probably 45 minutes, but I think I could do it again in 15 t0 20 minutes.
2009 Kia Sedona - We've had this van for just over two years, and given the state of the filter in the Mazda 5 I figured I should do this one as well. It was a lot easier - pop out the glove box, and remove an access plate behind the glove box. About 20 minutes this time, and I predict 10 minutes next time. The filter was not too bad, so it had likely been replaced previously. Glad I did it anyway.
These are the first vehicles I've ever owned with cabin air filters. Somehow we got by in the past without them.
