Factory-matched replacement air filters designed specifically for Coleman Mach 8430A Series Chill Grille 2 ceiling assemblies. Keeping these filters clean is one of the simplest ways to maintain cooling efficiency and protect your RV air conditioner from dust and debris buildup.
The Coleman Mach 8430-3691 filters are the correct factory-replacement filtration media for RVs equipped with the 8430A Series Chill Grille 2 ceiling assembly. These are not generic aftermarket filters -- they are engineered to fit the specific frame dimensions and airflow path of the Chill Grille 2 unit, ensuring a secure, rattle-free fit with no trimming or modification required.
Sold as a set of two (2) filters, this kit covers a full replacement cycle for the ceiling assembly. Coleman Mach recommends inspecting and cleaning or replacing these filters regularly, especially during heavy-use summer months or when camping in dusty environments.
Engineered to fit the 8430A Series Chill Grille 2 ceiling assembly with no cutting or modifications needed.
Comes with two replacement filters so you have a spare on hand or can replace both filter positions at once.
Traps dust, pet hair, and airborne particles before they reach the evaporator coil, preserving cooling performance.
Filter replacement requires no tools and takes only minutes -- accessible directly from inside the RV ceiling assembly.
A clogged or deteriorated filter forces your Coleman Mach AC unit to work harder to move air across the evaporator coil. This leads to reduced cooling output, increased compressor run time, and higher energy draw on your RV's electrical system -- whether you are on shore power or a generator. Replacing these filters at the start of each cooling season and mid-season during heavy use keeps the system running at its rated capacity.
Inspect filters monthly during summer travel. In dusty campgrounds or areas with high pollen counts, you may need to clean or replace filters more frequently than the standard seasonal schedule. A visually dirty filter is always worth replacing -- the cost of a filter set is far less than a service call for reduced cooling.
These filters are designed exclusively for the Coleman Mach 8430A Series Chill Grille 2 ceiling assembly. The Chill Grille 2 is a specific ceiling diffuser/return-air assembly used on select Coleman Mach rooftop AC units. If your ceiling assembly is a different series (such as the standard Chill Grille or a Deluxe Grille), different filter part numbers apply.
To confirm fitment, check the part number or model label on your existing ceiling assembly or refer to the Coleman Mach documentation that came with your unit. The assembly part number should include 8430A in the series designation.
These filters fit the 8430A Series Chill Grille 2 ceiling assembly only. They are not compatible with other Coleman Mach ceiling assembly models. Check your ceiling assembly series number before ordering to ensure correct fitment.
