Coleman Mach Chill Grille 2 A/C Filter | 8430-3691
Coleman Mach Chill Grille 2 A/C Filter | 8430-3691 — Product description
This is the genuine Coleman replacement filter for Mach rooftop air conditioners running the 8430A Series Chill Grille 2 ceiling assembly. Non-allergenic electrostatic fabric, hand washable, and it ships as a set of two so you can swap both openings at once or keep a spare on hand.
If you run a Coleman Mach rooftop air conditioner with the 8430A Series Chill Grille 2 ceiling assembly, this is the exact filter it takes. It's the genuine Coleman replacement, part number 8430-3691, and it ships as a set of two so you can do both at once or keep a spare in the drawer.
Here's why this matters. The filter on a rooftop A/C is the first thing the return air passes through before it hits the evaporator coil. Let it clog with dust and pet hair and two things happen. Your cabin airflow drops off, and the coil starts working harder than it should to pull the same air. Neither is good. A clean filter keeps the unit breathing and keeps the air coming out of the vents cold and strong.
These are made from a non-allergenic electrostatic filter fabric. The static charge in the material grabs fine dust and airborne particles that a plain foam pad would let slide right through. If anyone in the rig has allergies, that's the feature that earns its keep.
Best part? They're hand washable. When one loads up, pull it out, rinse it under the tap, let it dry, and drop it back in. No throwing money away every month on disposable pads. Most owners give them a rinse every few weeks in heavy use and a deeper clean at the start and end of the season.
Each filter measures 16.573 inches long by 6 inches wide and about a tenth of an inch thick, sized to drop straight into the Chill Grille 2 return openings. No trimming, no fuss. Just make sure your ceiling assembly is the 8430A Series Chill Grille 2 before you order, since Coleman uses different grille designs across the Mach lineup and the filter has to match the opening.
If you're not sure which grille you've got, take a look at the model tag on the ceiling assembly or send us a photo. We'll tell you straight whether this is the one you need.

Frequently asked questions
What air conditioners does this filter fit?
It's the replacement filter for Coleman Mach rooftop air conditioners that use the 8430A Series Chill Grille 2 ceiling assembly. Coleman runs several grille designs across the Mach line, so check that your ceiling assembly is the 8430A Chill Grille 2 before ordering.
Is this a single filter or a set?
You get two filters in the pack. That lets you replace both return openings at once, or clean one while the spare is in service.
Can I wash and reuse these filters?
Yes. The fabric is hand washable. When it loads up with dust, rinse it under the tap, let it dry fully, and put it back in. No need to buy disposables.
What are the filter dimensions?
Each filter is 16.573 inches long, 6 inches wide, and about 0.100 inch thick, sized to drop into the Chill Grille 2 return openings without trimming.
Are these good for allergies?
They're made from a non-allergenic electrostatic filter fabric. The static charge grabs fine dust and airborne particles that a plain foam pad would let pass, which helps if someone in the rig is sensitive to dust.
How often should I clean or replace them?
In heavy use, most owners rinse them every few weeks and do a deeper clean at the start and end of the season. Replace them when the fabric is torn or no longer comes clean.
