Keep your RV air conditioner running clean and efficient with these direct-replacement mesh filters. Designed specifically for Coleman Mach non-ducted ceiling assemblies, this two-pack ensures you always have a spare on hand -- or can refresh both filter slots at the same time.
Over time, AC filters trap dust, pet hair, pollen, and road debris. A clogged filter forces your Coleman Mach unit to work harder, reducing cooling output and shortening compressor life. Replacing the filter on schedule is one of the simplest -- and most overlooked -- RV maintenance tasks.
The 9430-3092 filter is the OEM-spec replacement mesh panel for Coleman Mach non-ducted ceiling assemblies. Non-ducted units deliver conditioned air directly into the living space through the ceiling assembly rather than through roof-mounted ductwork, and the filter sits in the ceiling box to catch particulates before they reach the evaporator coil.
Engineered to the same dimensions as the original filter. Drops in without trimming or modification.
Replace both filter positions at once or keep one as a backup. No need to reorder for months.
Rinse, air-dry, and reuse. Mesh construction allows thorough cleaning between full replacements.
Blocks dust and debris from reaching the evaporator coil, preserving cooling efficiency and system life.
RV air conditioners operate in conditions far dirtier than a typical home unit -- campground dust, unpaved roads, grass clippings, insects, and pet dander all accumulate rapidly. Coleman Mach recommends inspecting the filter at the start of each season and cleaning or replacing it monthly during heavy use. A dirty filter can reduce airflow enough that the evaporator coil ices over, causing the unit to cycle off and on and ultimately stressing the compressor.
Because this is a two-pack, you can swap in a clean filter immediately and wash the dirty one without any downtime -- a practical approach for full-timers and weekend warriors alike.
To clean: remove the filter from the ceiling assembly, rinse under warm water, gently shake out excess moisture, and allow to air-dry completely before reinstalling. Do not reinstall a wet filter -- residual moisture can promote mold growth on the evaporator coil.
The 9430-3092 filter is designed for Coleman Mach non-ducted ceiling assemblies. Non-ducted assemblies are identifiable by their return-air grille and direct-discharge louvers in the ceiling box -- there are no roof ducts running to individual vents. Common compatible unit families include:
If you are unsure whether your ceiling assembly is ducted or non-ducted, check the ceiling box: a non-ducted assembly has a single large return-air opening and discharges air directly into the room. A ducted assembly connects to flexible ductwork leading to individual vents elsewhere in the coach.
This filter (9430-3092) is for non-ducted ceiling assemblies only. Ducted Coleman Mach ceiling assemblies use a different filter part number. Check your ceiling assembly label or existing filter part number before ordering to confirm compatibility.
