Coleman-Mach 8430-3823 Ducted A/C Air Filter (Single, 12"X12", MERV 6 Rated)

The Coleman‑Mach 8430‑3823 Ducted A/C Air Filter (Single, 12" × 12") is the OEM replacement filter for Coleman‑Mach ducted ceiling assemblies. This framed filter uses a precision press‑fit design that locks directly into the ceiling grille, ensuring proper airflow and evaporator protection in RV and mobile‑home air‑conditioning systems.

Made from woven synthetic filter media inside a rigid plastic frame, the 8430‑3823 captures dust, lint, pollen, and debris while maintaining airflow for efficient cooling. Most suppliers list this filter as MERV 6, though some offer upgraded media rated MERV 9–10 depending on stock.
