The Coleman Mach 8430-3801 is the MERV 6 replacement air filter set for Coleman Mach ceiling assemblies in the Deluxe Chill Grille 2 series — compatible with the 8430, 9430, 9470, and 9630 ceiling assembly families. It is the most capable filter option designed for these assemblies, combining MERV 6 woven fabric filtration with non-allergenic electrostatic filter technology and hand-washable construction that makes it a reusable, long-service replacement rather than a strictly single-use consumable.
The electrostatic charge built into the filter fabric is what distinguishes the 8430-3801 from a standard mesh or passive woven filter. Rather than relying only on mechanical interception — where a particle must physically contact a fiber to be captured — an electrostatic filter actively attracts airborne particles via an electrostatic charge embedded in the filter material. This improves capture efficiency for smaller particles without requiring a denser, more restrictive filter medium. The result is MERV 6 performance in a 0.1-inch-thick profile that maintains airflow through the ceiling assembly.
When the filter loads with captured particles, it can be removed, rinsed by hand, allowed to dry, and reinstalled — rather than discarded. This makes the 8430-3801 the lowest long-term cost and lowest waste filter option in the Coleman Mach lineup for these ceiling assemblies. Each set of two provides a complete replacement for a standard Deluxe Chill Grille 2 ceiling assembly, and the precision press-fit frame ensures an accurate, gap-free fit.
Non-allergenic electrostatic charge actively attracts airborne particles — improves capture efficiency for smaller particles without adding airflow restriction
Rinse by hand, allow to dry, and reinstall — the only washable filter option in the Coleman Mach lineup for these ceiling assemblies; reduces ongoing replacement cost
Captures lint, household dust, pollen, dust mites, pet dander, and mold spores — full MERV 6 particle capture in a 0.1" thin profile for minimal airflow restriction
Engineered for accurate, gap-free seating in 8430, 9430, 9470, and 9630 series Deluxe Chill Grille 2 ceiling assembly housings — correct fit on every installation
Standard filters work by mechanical interception: a particle is captured only when it physically contacts a fiber in the filter medium. This approach requires a denser filter to catch smaller particles — and a denser filter means more airflow resistance. Electrostatic filters add a second capture mechanism. The filter fabric carries a permanent electrostatic charge — similar to static electricity — that creates an attractive force around the filter fibers. Airborne particles passing through the filter are drawn toward the fibers and held there even if they would otherwise pass through the gaps in the weave. This means: • Better capture of fine particles at the same filter density • Lower airflow restriction than a mechanical-only filter of equivalent particle capture performance • No power required — the charge is intrinsic to the filter material itself, not an active electrostatic device Non-allergenic designation: The filter material is specified as non-allergenic, meaning the filter fabric itself does not shed fibers or particles that could trigger sensitivities — important in an HVAC application where the filter is directly in the airstream reaching the RV interior. Washability note: Hand washing refreshes the filter by removing accumulated debris. The electrostatic charge is a property of the fiber material and is retained through gentle hand washing and air drying.
The 8430-3801's washable construction is one of its key advantages. When the filter is visibly loaded with debris or airflow through the ceiling assembly feels reduced: 1. Remove: Open the ceiling assembly's pop-out or snap-out retainer grilles and remove both filters. No tools required. 2. Rinse: Rinse the filter by hand under lukewarm running water. Work gently from the clean side through to the dirty side — this pushes captured debris out in the direction it entered rather than deeper into the fabric. 3. Dry: Allow the filter to air dry completely before reinstalling. Do not use a heat source to accelerate drying — air dry at room temperature. 4. Reinstall: Press-fit the dry filters back into the ceiling assembly housing and secure the retainer grilles. Even washable filters eventually reach the end of their service life as the filter fabric wears and the electrostatic charge degrades over many wash cycles. Inspect the filter fabric for tears, thinning, or loss of form after each wash, and replace with a new set when the filter no longer seats properly or shows physical deterioration.
The 8430-3801 is designed specifically for the Deluxe Chill Grille 2 ceiling assembly series. Compatible series: • 8430 series Deluxe Chill Grille 2 • 9430 series Deluxe Chill Grille 2 • 9470 series Deluxe Chill Grille 2 • 9630 series Deluxe Chill Grille 2 This filter is not interchangeable with the non-ducted series mesh or MERV 6 filters (9430-3092 and 9430-3441), which have different dimensions and frame configurations. Verify your ceiling assembly model number — typically on a label inside the assembly housing — before ordering.
All five Coleman Mach replacement filter options. Confirm your ceiling assembly series before ordering: Deluxe Chill Grille 2 (8430/9430/9470/9630) Filters: • 8430-3692 — Mesh, set of 2 • 8430-3801 — MERV 6 electrostatic woven fabric, washable, set of 2 (this item) • 8430-3821 — MERV 9, 12" × 12", single-pack Standard Non-Ducted Ceiling Assembly Filters: • 9430-3092 — Mesh, non-ducted, set of 2 • 9430-3441 — MERV 6 woven fabric, non-ducted, set of 2 Related part 9430-3091 is also noted by some authorized dealers as compatible with 8430/9430/9470/9630 series Deluxe Chill Grille 2 assemblies with the same dimensions and electrostatic washable specification — confirm applicability with your dealer if the 8430-3801 is not available.
All three options above are for the 8430/9430/9470/9630 series Deluxe Chill Grille 2 ceiling assembly platform. The 8430-3801 is the recommended choice for most owners — it provides MERV 6 electrostatic filtration, washable reusability, and a 2-year warranty. The MERV 9 option (8430-3821) offers higher particle capture but uses a single larger-format filter and a different installation configuration — confirm fit with your specific assembly before ordering.
