Grodan- MM BlockGrodan Stonewool (rockwool) is made from molten rock spun into cotton candy like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen

Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.

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.
