High-quality filters that really make a difference

I’m very impressed with the performance of these premium RV filters. The 2-pack is great value, and they fit our Dometic Duo Therm unit perfectly — no adjustments needed. The MERV 6 triple-layer design noticeably improved the air quality inside our camper; less dust, better airflow, and the whole space feels fresher. Installation was quick and easy. The filters are thick and durable, much better than the flimsy ones we’ve tried in the past. Will definitely reorder for the next trip!

Great performance and perfect fit — worth every penny

We’ve been RVing for years, and this 2-pack of Airfeel filters is hands-down one of the best upgrades we’ve made. The 7.5"x14" size fits our Dometic Duo Therm unit exactly as expected, and the triple-layer MERV 6 design really improves air circulation and freshness inside our trailer. Within a day of switching them in, we noticed less dust buildup and better airflow overall. They’re also sturdy — not the flimsy kind that bends or sheds fibers. Having the second filter on hand is super convenient for road trips. We’ll definitely be sticking with this brand from now on.

Great 2-pack deal – clean air and easy install

These filters are a great fit for our Dometic Duo Therm system. The MERV 6 triple-layer build really makes a difference — the air smells fresher, and we’ve noticed way less dust. Having a 2-pack is super convenient when you're on the road. Definitely recommend for anyone looking to upgrade from the flimsy stock filters.
