Excellent air quality and value
Size: 1 Count (Pack of 1)
Much better than the standard filter for air quality. Similar price to the ones that are thrown away 2-3 times per year.

Great Air Filter
Size: 9.6" x 11.1" x 2.2"
Some review’s will say “it’s an air filter, blah, blah, blah”. These reviews are written by the same people that think “water is water”. I’m not one of those people. I’ve noticed that the air smells better, cleaner. I’ve also noticed that the air blows a little stronger. It’s very easy to install, fits perfectly and it’s reusable so it saves you money over the long term and it reduces landfill waste.

THE cabin air filter to use!
Size: 9.6" x 11.1" x 2.2"
I replaced the OEM cabin air filter when I bought my truck, like I always do. 2019 & 2020 Ram 1500's suffer from an underperforming AC system in the summer due to a blend door in the dash not closing completely. Having any kind of restrictive cabin air filter only exacerbates the problem. I bought this filter on the recommendation of many owners who had done the same with great results. I was presently surprised at the increase in air flow coming out of the vents. I also like that in K7N fashion, it is washable and reusable, effectively making it a lifetime filter. Don't overthink it. Yes it costs more, but you will save $$ in the long run with this filter. I am sure this filter fits many other makes & models of vehicles and will improve the airflow of any vehicle it is installed in.

Easy to install and fits great
Size: 9.6" x 11.1" x 2.2"
Fits great and seems better quality than any paper filter. Nice rubber edge makes a good seal and the airflow is good. Used in a 2023 Ram 3500. Installation was easy. So far it appears to filter out all the dust and odors.
