2020 Honda Odyssey Cabin Air Filter Replacement — Two-Filter System, Both Covered
2020 Honda Odyssey Cabin Air Filter Replacement — Two-Filter System, Both Filters Covered
I've done this job on the fifth-gen Odyssey, and the thing nobody tells you is that the 2020 Odyssey has two separate cabin air filters — not one. Most people replace only one and wonder why their HVAC still smells musty three months later. Here's exactly how I handle both, what to expect, and the only mistake worth worrying about.

Get the DIY Mechanic SystemThe 2020 Honda Odyssey uses a dual-filter HVAC system — two separate filter elements in a single housing behind the glove box. This dual arrangement is unique to the Odyssey among Honda's consumer lineup.
Honda rates replacement at 15,000 miles or 12 months. In heavy traffic or outdoor parking, check at 10,000 miles.
Tools & Parts Needed
| Item | Spec / Part Number |
|---|---|
| Filter 1 (front/primary) | Honda 80292-TBA-A11 |

| Dimensions | ~10.9" × 9.0" × 1.1" each |
| Aftermarket (each) | FRAM CF10134, Wix 24705, Bosch 6062C (HEPA carbon) |
| Tools required | None |

Buy two filters. Both use the same part number. Order a two-pack or confirm you have two identical filters before starting.
Step-by-Step Instructions
1. Open and Drop the Glove Box
Open the glove box fully. Release the plastic damper rod on the right interior wall by pinching its end and pulling it free from the clip. Let it hang.
Squeeze both side walls of the glove box inward simultaneously — the plastic walls flex enough to let the pivot tabs clear the dashboard frame stops. While squeezing, let the box swing all the way down to hang vertically. The filter housing is now fully exposed.
2. Open the Filter Housing
Locate the rectangular housing with a latch tab on the bottom. Release the tab and swing the door open. You'll see two filter elements stacked on top of each other.
3. Remove Both Filters — Note Airflow Arrows
Before removing: photograph the airflow direction arrows on both filters. Five seconds now eliminates all guesswork on reinstall.
Pull the front (outer) filter element out first. Then pull the rear (inner) filter element. Hold both up to light — if either shows heavy gray-brown loading, it's past due. The front filter normally catches more particulate.
While housing is open, wipe out any debris with a dry rag.
4. Install New Filters
Install the rear (inner) filter first with the airflow arrow matching the original direction. Install the front (outer) filter second, same orientation. Both should slide flush with no binding.
Close and latch the housing door.
5. Restore the Glove Box
Lift the box up, squeeze sides inward to clear the frame stops, release — clicks into normal open position. Reconnect damper rod. Close and test.
Common Mistakes
Only replacing one of the two filters. This is the most common Odyssey cabin filter mistake. The two filters are stacked in a single compartment. If you only reach in and pull the front element, you've done half the job. The rear filter is still loaded and restricting airflow. Always pull both, inspect both, and install two new filters simultaneously.
Pro Tips
- Activated carbon filters are worth the upgrade for the Odyssey specifically — the van's large cabin volume and recirculate mode concentrate odors. Bosch HEPA 6062C carbon filters cost
$30 each ($60 for both) and the improvement is immediately noticeable. - Reduced airflow at the same fan settings is often clogged filters before a blower motor issue — always check filters first.
- Spring and fall are the best times to replace: fresh filter before allergy season and before cold/wet season.
