RV Air Conditioner Filters

What RV AC filter material should I choose?

This collection has four RV AC filter materials: foam pads, electrostatic filters, MERV 6 media, and MERV 10 media. Foam pads are washable and reusable. They catch dust, lint, and pet hair with little restriction on airflow. MERV 6 media traps the same coarse particles plus pollen. MERV 10 media also captures finer dust, but it restricts airflow more, so confirm your unit can handle it before you switch. Most OEM rooftop units, including Coleman RV air conditioners, ship with foam or similar low-restriction filters. That is the safest replacement if you are unsure.

How does an electrostatic RV air filter differ from a foam filter?

An electrostatic RV air filter uses layered synthetic media. Air moving through the media builds a static charge, and that charge pulls in finer particles than plain foam would trap. Like foam, an electrostatic filter can be washed and reused. Before ordering, check that the frame thickness matches the slot in your ceiling assembly or return air grille, because electrostatic filters are often thicker than the foam pad they replace.

Can I cut an RV AC foam filter pad to fit my unit?

Yes. Some foam filter pads in this collection are sold as sheets you trim with scissors. Others are pre-cut for a specific ceiling assembly. Each listing states which type it is. If you buy sheet foam, measure the length, width, and thickness of your existing filter and cut the new pad to match. Gaps around the edges let unfiltered air reach the evaporator coil.

How do I find the right Atwood Air Command filter replacement?

Start with the model number on the label inside your ceiling assembly, then measure your current filter. Atwood Air Command filters are sized to fit that unit's return air grille, so the dimensions and model number together confirm the fit. The same rule applies to other brands. For Furrion units, check filters and grilles in Furrion RV air conditioner parts and accessories. If you still can't confirm the fit, text or call 817-984-1852 with your model number and we'll match the correct filter.

How often should I clean or replace RV air conditioner filters?

Check your filter every two weeks while you run the AC regularly. Wash foam and electrostatic filters in warm water with mild soap, and let them air dry completely before you reinstall them. Replace MERV 6 and MERV 10 media filters instead of washing them. A clogged filter cuts airflow and can cause the evaporator coil to ice over. On ducted systems, the filter sits behind the return grille of the Coleman ducted ceiling assembly and other similar ceiling units.
