We only sell real high-quality air filters for RVs, so our product line is very easy to navigate on our website. Having experienced camping for over 35 years without a good air filter on the open road in our RV’s many of our ac units kept building micro dust on our coils reducing cooling temperatures we discovered that our original foam filter didn’t really collect much of anything and for sure no micro dust which over time was affecting the performance of our AC units even with a schedule washing weekly. The need for an air filter that would work for cutting dust was and is a top priority. Those of us with sensitivity to allergies, dust, and pet hair, dander need a really good quality air filter To that effect we offer the following.

A single package of 4 RV AIR filters for $17.95. This is the perfect and best OEM replacement and installs in seconds. the best way to get efficiency out of the RV AIR filters is to replace yearly or for full-timers with AC really running every 90 days.

If you want to take the leap and get your RVs ac unit’s into a working condition that is better than the standard foam you are currently using, you can purchase our 2 pack of RV AIR filters for $30.95. This is a better value and for those RV owners who like to have backups

CAN THEY BE WASHED OR RINSED?  No, when it comes time to replace the filters, order new ones. You’ll be shocked out much is in those dirty filters. If they get wet, the dust that has built up inside the filters that you can’t see dries and turns into a clump of mud. This is very bad for your AC unit. We can ship to any RV site where mail can be delivered.
