I purchased this filter based on another review that mentioned it being a perfect fit for a 2023 Jeep Grand Cherokee 4xe, and can confirm that it does fit perfectly! My partner smokes in the Jeep sometimes and the air conditioning was starting to smell so I'm hopeful that having the added carbon in this filter will help reduce that smell. I'm a bit disappointed, I was told when I bought the vehicle that it had some "special" air filtration but that was not the case.. the filter I pulled out looked just like any other basic filter you'd find in any vehicle. I would assume from comparing the new filter that it will do a better job (with addition of carbon and foam around the filter for a better seal). Very easy to install, just had to release the cord on the left side of the glove box and the filter fits right behind there.
