Genuine Coleman Mach OEM replacement electrostatic filter set for Deluxe ChillGrille and Bluetooth ceiling assemblies. Non-allergenic electrostatic fabric captures more airborne particles than standard filters. Hand-washable and reusable. Set of 2 — one for each side of the ceiling assembly. Black. 15.872" × 4.170" × 0.100" per filter. 0.05 lbs. 90-day limited manufacturer warranty.
The Coleman Mach 9430-3091 is the OEM replacement electrostatic filter set for Deluxe ChillGrille and Bluetooth ceiling assemblies used with 8000 and 9000 series Coleman Mach ducted and non-ducted air conditioners. The set includes two filters — one for each side of the ceiling assembly — providing a complete replacement for both filter positions in a single purchase.
The filters use non-allergenic electrostatic filter fabric, which generates a passive static charge as air passes through. That charge attracts and holds fine airborne particles — dust, pollen, pet dander, and other small particulates — more effectively than standard mesh or fiberglass filters of comparable thickness. Cleaner return air means less particulate buildup on the evaporator coil, which helps maintain airflow efficiency and heat transfer performance over time.
The filters are hand-washable and fully reusable. Rinse under lukewarm water from the clean side through the dirty side to push captured particles out — not deeper in. Allow to air dry completely before reinstalling. The Deluxe ChillGrille and Bluetooth ceiling assemblies use pop-out retainer grilles for tool-free filter access, making routine filter maintenance straightforward.

Hand-wash under lukewarm water and air dry — no disposable filter waste, no ongoing replacement cost beyond an occasional fresh set
Two filters included — one per side of the ceiling assembly — replaces both filter positions in the Deluxe ChillGrille or Bluetooth assembly at once
Deluxe ChillGrille and Bluetooth assemblies feature pop-out retainer grilles — no tools needed to remove, wash, and reinstall the filters
The 9430-3091 filters are designed for repeated washing. Follow these steps to clean without damaging the electrostatic fabric: 1. Remove: Pop out the retainer grilles and remove both filters from the ceiling assembly 2. Rinse: Hold the filter under lukewarm running water and rinse from the clean side through to the dirty side — pushing captured particles out rather than deeper into the fabric 3. Dry: Allow both filters to air dry completely before reinstalling — do not use heat to speed drying 4. Reinstall: Snap the filters back into the assembly and replace the retainer grilles Inspect filters every 30–90 days depending on use environment. Campground dust, pet hair, and sandy locations will require more frequent cleaning. Replace filters when the fabric shows visible damage, tearing, or can no longer be cleaned to a usable condition.
