A clean air conditioner filter keeps your Dometic unit running efficiently and helps maintain air quality inside your RV by capturing dust, pollen, and other airborne particles. A clogged filter restricts airflow, which forces the system to work harder and can reduce cooling performance over time.

Dometic filters are available in both reusable foam and mesh styles and non-washable pleated options, depending on your ceiling assembly. Reusable filters can be vacuumed and washed in warm soapy water, while pleated filters should be replaced once they show visible buildup. Most setups benefit from a full filter replacement at least once a season.

Filter dimensions vary by ceiling assembly model, so confirm your AC model number from the rooftop shroud label before ordering to ensure the correct fit.

How do I find the right RV AC filter for my Dometic air conditioner?

Match the filter to your Dometic ceiling assembly, the interior unit with the return-air grille, not to the rooftop unit. Remove the grille and check the model label on the ceiling assembly. Then confirm whether your system is ducted or non-ducted, because the two use different filter shapes and sizes. If the label is missing or worn, text or call 817-984-1852 with your rooftop unit's model number and our team will help you identify the correct filter before you order.

When should I clean or do an RV air conditioner filter replacement?

During regular use, check your filter every two weeks. Most Dometic return-air filters are washable foam or mesh pads. Rinse them in warm water with mild soap, let them air dry completely, and reinstall them. Replace the filter when the media tears, turns brittle, or stays discolored after washing. Running the AC without a filter lets dust build up on the evaporator coil, which reduces airflow and cooling capacity.

Will a Dometic camper AC filter fit a Coleman or Furrion air conditioner?

Usually not. Each manufacturer shapes its filters to fit its own ceiling assembly grille, so a Dometic filter will not reliably fit another brand's unit. For Coleman systems, start with our Coleman ducted ceiling assemblies or the Coleman RV air conditioner range to identify your setup. Furrion owners can find matching filters and parts in Furrion RV air conditioner parts and accessories.

What are the signs that my RV air filter needs replacing?

Watch for weak airflow from the vents, a musty smell when the AC starts, or frost forming on the evaporator coil. A filter that has collapsed, split at the edges, or no longer sits flat behind the grille should be replaced. Washing will not restore it.

Do RV AC filters qualify for free shipping?

Yes. Orders over $100 ship free. Dometic AC filters are small and light, so many owners order a spare set. That way you can swap in a clean filter while the used one dries after washing.
