Review on Premium RV Air AC Filter: Enhance Airflow & Cleanse RV Air - Pack of 2, MADE in USA, MERV 6 Rated by Jason Hayes

Perfect for Coleman Mach AC Unit. No pruning required. Much tighter than the foam filter he replaced. Definitely picks up more dirt from the air. Only used on two trips to a paved campground in Arizona and already quite dirty. I am not sure if they will last as long as advertised. UPDATE 7-10-21: After only using this filter 2 times at campgrounds on Lakes Mojave and Havasu, the filter became so clogged that almost no air was coming out of the vents. I had to flush the filter with water to get through the bad weather. Dirt is accurately captured but does not last more than 10 days. If it was reusable I would buy it again but not worth the money for life
