Coleman 8430-3801 MERV 6 RV AC Filters | Set of 2
Coleman 8430-3801 MERV 6 RV AC Filters | Set of 2 — Product description
If you run a Coleman ducted rooftop air conditioner in your RV, this is the return-air filter in the ceiling assembly most people forget until the airflow drops. Genuine Coleman MERV 6 replacement, part 8430-3801, shipped as a set of two so you've always got a spare on the shelf.
If you run a Coleman ducted rooftop air conditioner in your RV, the return-air filter in the ceiling assembly is the part most folks forget about until the airflow drops off. This is the genuine Coleman replacement, part number 8430-3801, and it ships as a set of two so you've got a spare ready to go.
These are MERV 6 rated filters. In plain terms, that means they catch the dust, pollen, and lint your ducted system pulls through the return grille before it reaches the evaporator coil. A clean filter keeps the coil clean, and a clean coil is what keeps your unit cooling hard on a hot afternoon. Let the filter load up with grime and the whole system works harder for less cold air.
They drop into the return-air opening on Coleman ducted ceiling assemblies. No tools, no fuss. Pop the return grille, pull the old filter, slide the new one in, close it back up. Most owners knock it out in under a minute at a rest stop.
How often? Depends on where you camp. If you're parked under pines or rolling down dusty forest roads, check it monthly and swap it when it looks gray. Weekend campers in cleaner air can usually go a full season. Either way, having the second filter from the set already on hand means you're never running a dirty one just because you forgot to reorder.
One honest note. These are return-air filters, not a medical-grade element. MERV 6 is the right call for an RV rooftop unit. It filters well without choking the airflow the blower needs to move. Go too dense and you starve the system. Coleman spec'd MERV 6 for a reason.
Not sure your unit is a ducted ceiling assembly? Look up at the vents. Ducted systems feed several small ceiling vents through a plenum. Non-ducted units blow straight down out of a single ceiling box. This filter is for the ducted setup. Ask us if you're unsure and we'll help you match it.

Frequently asked questions
What does MERV 6 mean on an RV AC filter?
MERV 6 is a rating for how well the filter traps airborne particles like dust, pollen, and lint. For an RV rooftop unit it's the sweet spot. It filters the return air well without being so dense that it chokes the airflow your blower needs to move.
How many filters come in this set?
Two. You get a matched set of MERV 6 filters, so you can swap one in now and keep the second on the shelf for the next change.
Which Coleman units does this fit?
It's the return-air filter for Coleman ducted ceiling air conditioner assemblies. If your system feeds several small ceiling vents through a plenum rather than blowing straight down from one box, it's ducted. Ask us with your model number if you're not sure.
How often should I replace the filter?
Depends on your conditions. Camping under trees or on dusty roads, check it monthly and swap it when it looks gray. Cleaner air and lighter use, you can usually go a full season. When airflow feels weak, it's time.
Can I wash these and reuse them instead?
These are designed to be replaced, not washed, which is why they come as a set of two. Running a rinsed-out filter tends to leave you with weaker filtration and restricted airflow. Just swap in a fresh one.
Would a higher MERV filter cool better?
No. A denser filter restricts the airflow the blower depends on, which makes the unit work harder for less cold air. Coleman spec'd MERV 6 for this system on purpose. Stick with it.
