The cabin air filter in a 2020 Honda Accord is located behind the glove box on the passenger side. Access it by lowering the glove box and removing the filter cover, then replace the filter as needed.
Overview of the location
The filter sits in a rectangular housing on the passenger side of the dash, just behind the glove box. To reach it you’ll need to drop the glove box by releasing its stops or dampers, then uncover the filter housing with a small panel or cover.
What you’ll need
Before you start, gather these items to ensure a smooth replacement process:
- A replacement cabin air filter compatible with the 2020 Honda Accord (often a universal size used by many Hondas)
- A flashlight or phone light to see inside the housing
- Optional: a clean microfiber cloth to wipe the housing before installing the new filter
Having these on hand helps you inspect the housing and complete the swap without extra trips to the parts counter.
How to access and replace the cabin filter
Follow these steps to locate, remove, and replace the cabin air filter. The exact steps may vary slightly by trim, but the general procedure remains the same.
- Open the passenger-side glove box and empty its contents.
- Gently collapse or lower the glove box by pressing in the sides to release the stops; let the box hang down.
- Look for a rectangular panel or cover just behind the glove box that conceals the filter housing; grasp the tabs and remove the cover.
- Remove the old cabin air filter from the housing. Note the orientation of the old filter for correct replacement.
- Clean the inside of the housing with a microfiber cloth if you see dust or debris.
- Insert the new filter with the airflow arrows pointing in the direction of airflow through the HVAC system (toward the interior of the car). Make sure it sits snugly in the housing.
- Replace the housing cover and ensure it snaps back into place.
- Raise the glove box back up and reseat it. Reconnect any dampers and ensure the box opens and closes smoothly.
After replacing, run the climate system on a few minutes to verify normal airflow and listen for any rattling or loose parts. If you notice reduced airflow or odors, double-check the filter seating and orientation.
Maintenance notes and tips
Cabin filter replacement intervals can vary by driving conditions. In general, Honda recommends inspecting and replacing the cabin air filter roughly every 12 to 15 months or about every 15,000 miles, whichever comes first, but always consult your owner’s manual for the exact interval for your vehicle and climate. If you drive in dusty areas or frequently use the recirculation setting, consider checking the filter more often.
Summary
For a 2020 Honda Accord, the cabin filter sits behind the passenger-side glove box. Access it by lowering the glove box, removing the filter cover, replacing the filter with the arrows oriented correctly, and reassembling. Regular checks and timely replacement help maintain clean air and optimal HVAC performance.
