Keep your Dometic ducted air conditioner breathing clean and running efficiently with this genuine replacement filter. Sized at 12 x 16 inches and designed specifically for the Quick Cool ducted return air package, this filter traps airborne dust and debris before it can restrict airflow or foul the evaporator coil -- protecting cooling performance and extending the life of your A/C unit.
Dometic's Quick Cool ducted return air system routes conditioned air through ceiling ducts to multiple zones in your RV. The return air path draws cabin air back through a dedicated filter -- this 12 x 16 inch panel -- before it reaches the evaporator. A clogged or missing filter starves the coil of airflow, reduces cooling capacity, and can cause the unit to freeze up or short-cycle.
Part number 3108015.003 is the factory-specified replacement for this filter slot. It installs directly into the ducted return housing with no cutting or modification required.
Designed to the factory 12 x 16 in. opening on compatible Dometic ducted A/C units -- no trimming, no adapter needed.
Rinse with water, let dry, and reinstall. No disposable filter to stock or dispose of -- one filter lasts the life of the unit with proper care.
Verified compatible with Dometic models 620012301, 620012301C, and 620015203 Quick Cool ducted A/C systems.
Backed by Dometic's limited 2-year manufacturer warranty against defects in materials and workmanship.
RV interiors collect pet hair, road dust, fiberglass particles, and cooking grease faster than most residential spaces. A ducted A/C system recirculates all of that through a single return path. Checking and cleaning this filter every 30 days during heavy use -- or at the start and end of each camping season -- keeps static pressure low and efficiency high.
Access the return air grille on your ceiling duct assembly -- typically located in the main living area or bedroom zone depending on your coach layout. Release the grille clips or screws, slide the old filter out, and slide the new filter in with the airflow direction arrow (if present) pointing toward the evaporator. Reinstall the grille. No tools required in most installations.
