It's a 12 inch by 12 inch MERV9 filter that pulls dust, pollen, and dander out of the air before it reaches your rig's return, so your rooftop AC breathes easy and your cabin air stays clean.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the genuine Coleman-Mach replacement air filter for ducted ceiling assemblies, part number 8430-3823. It measures 12 inches by 12 inches and carries a MERV9 efficiency rating, so it pulls more dust, pollen, and airborne grit out of the air before it ever reaches your rig's return.\u003c\/p\u003e\n\u003cp\u003eIf you run a Coleman-Mach ducted rooftop air conditioner, the filter sits up in the ceiling assembly and does quiet work on every trip. Over a season it loads up with road dust, campfire ash, and pet dander. A clogged filter chokes airflow, makes the blower work harder, and slowly cuts your cooling. Swapping in a fresh MERV9 is about the cheapest maintenance you'll do all year, and it makes a real difference on a hot afternoon at the campsite.\u003c\/p\u003e\n\u003cp\u003eMERV9 is a solid step up from the basic foam and mesh screens a lot of units ship with. It captures finer particles while still letting the blower move plenty of air, so you get cleaner cabin air without starving the system. That balance matters in an RV, where the AC is often running wide open in the middle of July.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as simple as it gets. Pop the return-air grille on your ducted ceiling assembly, slide the old filter out, and drop this one in. No tools, no wiring, no fuss. We tell folks to check it monthly during heavy use and replace it at least once a season, more often if you camp in dusty country or travel with pets.\u003c\/p\u003e\n\u003cp\u003eOne note before you order: this is a single 12 x 12 filter sized for Coleman-Mach ducted ceiling assemblies. It won't fit a non-ducted unit, so double-check that your ceiling assembly is the ducted type. If you're not sure which setup you've got, measure your existing filter and match it to the 12-inch square footprint.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eMERV9 efficiency rating captures fine dust, pollen, and pet dander for cleaner cabin air\u003c\/li\u003e\n  \u003cli\u003e12 inch by 12 inch size fits Coleman-Mach ducted ceiling assemblies\u003c\/li\u003e\n  \u003cli\u003eGenuine Coleman-Mach part 8430-3823, a direct OEM replacement\u003c\/li\u003e\n  \u003cli\u003eTool-free swap: lift the return grille, slide the old filter out, drop this one in\u003c\/li\u003e\n  \u003cli\u003eBalances higher filtration with strong airflow so the blower isn't starved\u003c\/li\u003e\n  \u003cli\u003eSingle filter sized for ducted rooftop RV air conditioners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the MERV9 rating mean?\u003c\/summary\u003e\n    \u003cp\u003eMERV9 is a measure of filtration efficiency.
