The FRAM fresh breeze cabin air filters fit perfectly. Dunno if the '14 and '15 are the same, but the 14 is FRAM CF11183 resh Breeze Cabin Air Filter.
As others have noted, even carbon impregnated filter won't deal with dead kitty cats in the A/C.
I would start with FrigiFresh, where even in Colorado it can stink up since the outside humidity isn't what matters--it is how humid [very] it is in the innards of the A/C.
Apply at least every month or so. And if you replace the filter put a really good dose of it down into the innards with the filter out.
There are treatments that flood the A/C with a cleaning and deodorizing foam, but a good dealer would suggest FrigiFresh first.
You MAY have something in there... if you park under shedding trees or similar and don't carefully clean the underhood intakes for the A/C.
