Coleman Mach 6798-3751 A/C Filter 16.3 x 16.3 In
Coleman Mach 6798-3751 A/C Filter 16.3 x 16.3 In — Product description
Keep your Coleman Mach rooftop A/C moving clean air with this genuine 6798-3751 return-air filter. It fits the 6798-309 ducted ceiling assemblies, measures 16.3 by 16.3 inches, and uses non-allergenic fabric you can rinse by hand and reuse. Ships as a single filter.
This is the return-air filter that keeps your Coleman Mach rooftop A/C breathing clean. It fits the 6798-309 ducted ceiling assemblies, measures 16.3 inches by 16.3 inches, and drops right into the ceiling grille where the old one came out. No tools, no fuss.
The fabric is non-allergenic, so it traps dust and pollen before they cycle back through the coach. And when it gets dirty? You don't toss it. Rinse it by hand in the sink, let it air dry, and slide it back in. That's it.
If you've been running your rig all season, a clogged filter is the number one reason airflow drops off and the unit starts working harder than it should. Swapping in a fresh one is the cheapest thing you can do for cooling performance. We'd keep a spare on the shelf so you're never caught mid-trip with a filter that's seen better days. This one ships as a single filter.
