Replacing the cabin air filter in your 2020 Honda Accord can be done in about 5 to 10 minutes and requires minimal tools. To get started, you’ll locate the filter behind the glove box, swap in a fresh unit, and reassemble. It’s a straightforward maintenance task that helps keep the interior air clean and the HVAC system running efficiently.
In the 2020 Accord, the cabin air filter sits in a housing behind the glove box. Replacing it removes dust, pollen, and odors from the incoming air before it reaches the cabin. This guide provides a clear, step-by-step method, plus tips on when to replace and what kind of filter to choose, so you can complete the job with confidence.
What you’ll need
Before you start, gather the items below to ensure a smooth replacement and to avoid multiple trips to the store.
- Replacement cabin air filter compatible with the 2020 Honda Accord (standard or activated carbon if you want odor control)
- Flat-head or Phillips screwdriver (if your trim uses screws to secure the filter housing)
- Clean rag or microfiber cloth
- Disposable gloves (optional)
- Flashlight or phone light for better visibility inside the glove box area
With these supplies on hand, you’re ready to begin the replacement process.
Step-by-step guide
Follow these steps in order to swap the filter quickly and correctly.
- Turn off the engine and set the vehicle in park. Open and empty the glove box.
- Gently squeeze the sides of the glove box to release the dampers and allow the glove box to swing down fully, exposing the cabin air filter housing behind it.
- Locate the filter housing cover. It is a rectangular panel secured by clips or small tabs; release the clips or tabs to remove the cover.
- Carefully pull out the old cabin air filter. Note the airflow direction printed on the filter frame so you install the new one correctly.
- Inspect the housing for debris and wipe it clean with a dry cloth if needed.
- Insert the new filter into the housing with the airflow arrow pointing toward the cabin (downward or toward the interior, depending on the model). Ensure it sits flush in the slot.
- Reattach the housing cover and secure all clips or screws firmly.
- Lift the glove box back into position, ensuring the dampers re-engage and the box closes smoothly. Remove any packing materials from the new filter.
After installation, turn the ignition to ON and run the fan briefly to confirm proper airflow and that there are no unusual noises.
Maintenance tips and considerations
Regular maintenance helps maximize HVAC performance and air quality inside your car. Consider these guidelines and options.
- Replacement interval: Check your owner’s manual, but a common cadence is every 12–24 months or about 15,000–30,000 miles, depending on driving conditions (dusty roads, heavy pollen, or urban environments may require more frequent changes).
- Watch for signs: Reduced airflow, musty odors, foggy windows, or allergy symptoms from passengers can indicate it’s time to replace the filter.
- Filter type: If odors are a frequent issue, choose an activated carbon (odor-absorbing) filter. For enhanced filtration, some buyers opt for high-efficiency or allergen-focused filters.
- Where to buy: Authorized Honda parts, reputable auto parts stores, or online retailers. Ensure the filter is listed as compatible with the 2020 Accord.
- Indicator considerations: Some vehicles have a cabin air filter reminder, but many Hondas do not. If your model lacks an indicator, set a reminder based on mileage or environmental factors.
Regular replacement maintains interior air quality, preserves HVAC efficiency, and helps prevent odors from developing inside the vehicle.
Summary
Changing the cabin air filter on a 2020 Honda Accord is a quick, tool-light maintenance task that you can perform at home. Gather a compatible filter, access the housing behind the glove box, replace the old unit with proper orientation, and reassemble. Following recommended replacement intervals and choosing the right filter type will keep the interior air clean and the climate control functioning smoothly.
