Four washable, reusable polyurethane foam filters sized to drop into Dometic ducted return air ceiling assemblies. Keeps conditioned air clean without choking airflow, and each filter rinses clean for reuse season after season.
Dirty or missing return air filters let dust, pet dander, and road grit circulate through your RV and collect on the evaporator coil, reducing cooling efficiency and increasing wear. The Camco 40408 replaces the factory foam pads in Dometic ducted ceiling assemblies so you can maintain good indoor air quality and protect the unit itself.
The open-cell polyurethane foam construction captures airborne particulates while maintaining enough airflow to keep your A/C running at rated capacity. Unlike paper or pleated filters, these foam pads can be rinsed, dried, and reinstalled -- no recurring filter purchases required.
Open-cell polyurethane foam rinses clean with water. Allow to air dry fully before reinstalling.
Four filters per package -- enough to stock spares or service multiple return air registers in the same rig.
Cut to 13-7/8 x 7-13/32 in. to fit Dometic ducted grilles measuring 7-11/16 x 14-1/8 in.
Foam density balances filtration and airflow, avoiding the pressure drop that can cause icing on the evaporator coil.
These filters are designed for Dometic ducted return air ceiling assemblies that use a grille opening of approximately 7-11/16 in. x 14-1/8 in. The filter pad itself measures 13-7/8 in. x 7-13/32 in. and slides into the grille frame behind the louvered cover.
Compatible Dometic ducted systems include units installed in many Class A, Class C, and fifth-wheel applications that use ceiling-mounted return air registers. Verify your existing grille opening dimensions before ordering if you are unsure of your model.
Because these filters are washable, a single pack of four can last multiple seasons with routine cleaning. Camco recommends inspecting and rinsing filters at the start of each cooling season and after extended dusty-road travel.
RV A/C filters in ducted ceiling assemblies are often out of sight and therefore out of mind. Add filter inspection to your pre-season checklist. A clogged filter causes the A/C to work harder, draws more current from your coach batteries or shore power, and reduces cooling output -- all problems that are easily avoided with a rinse.
These are open-cell foam pads intended to capture larger airborne particles -- dust, hair, and coarse debris. They are not rated for fine particulates, allergens, or smoke filtration. If you need higher-efficiency air filtration inside your RV, supplement with a standalone air purifier; do not substitute a higher-density filter in the return air assembly without verifying that your A/C unit can handle the added static pressure.
