I decided to check my cabin air filters today. It has been a couple weeks shy of a year and 10k miles.
Besides the leaves, the pleats were fairly black, but not as bad as others I have had.
Time to buy a new filter the next time I go to town.
For comparison, this is what my Titan cabin filters looked like with the same mileage. Besides the pleats being full of dirt/crap, the pleats had started to rot away.
