Worked perfect for my Jeep Grand Cherokee L
Pleasantly surprised with the quality. It seemed better than the original filter that I took out of my 2021 Jeep Grand Cherokee L. Seems like it’ll last a while and I really like the charcoal addition. Has worked well so far and car smells clean.

Quality filter
Nice filter, fits perfect in the WL model (not the WK!) I will buy this one again, far superior to the OEM filter from the dealer!

loose fit fixed with foam stripping
I added a little bit of foam weather stripping for a more sealed fit.

Insanely great cabin air filter!
This filter absolutely blows away the Mopar cabin filters. It has foam around the outside which sealers the filter to the housing. Will definitely buy again!
