I had a '97 Honda CRV (my son has it now). That cabin air filter required removing the glove box, side panel, and a steel bar with 4 bolts and two screws that were nearly impossible to reach. The three that fixed the left side of this bar required contorting your hand while using a small socket and screw driver (different fasteners). Then you can open the plastic enclosure and change the air filter; that is after you force a large, stubborn wire harness out of the way. Minimum time required is at least 30 minutes (with practice).
Why oh why do auto manufacturers make cabin air filters this way.
On both my Challengers, I open the hood, snap open the cover, and remove the filter. A 30 second job with no tools needed.
I change my cabin air filters every three years or 30,000 miles.
