Good purchase.
Fit perfect in my 2023 jeep grand Cherokee L. Value is great especially for a Hepa filter. Easy to install no problems at all.

Hopefully This One Will Stop the Critters
This appears to be a nice filter. We have had problems with mice getting in the vehicle through the air vent intake. This is another poor design of the Jeep Grand Cherokee. We had the same issue with an earlier year of the same model and I ended up putting a grill in front to prevent the critters from coming in. I’m hoping this ai filter will be more effective as it is significantly stiffer than other filters. I think the critters are able to lift the end of the filter to slip by and get in the cab. Time will tell, but I do like this one for potentially being more difficult to go by. I would hope Stelantis would fix this, but I won’t hold my breath.
