The cabin air filter in a 2020 Honda Civic sits behind the glove box on the passenger side. Accessing it requires lowering the glove box and removing a cover to reach the filter.
Location and access
The filter is housed in a rectangular chamber inside the HVAC assembly, tucked behind the glove box on the passenger side. To reach it, you’ll need to open the glove box, release its sides or damper to allow the box to drop, and then locate the filter cover on the right side of the housing. The cover is usually secured with a snap or a simple tab that you rotate or pull to open.
What you'll need
Gather these items before you begin so you can replace the filter without extra trips.
- New cabin air filter (OEM Honda or compatible)
- Clean microfiber cloth
- Small screwdriver or coin (optional, for prying the cover)
- Flashlight
Having the right filter and a couple of basic tools on hand helps ensure a smooth replacement.
Steps to access the cabin air filter
Follow these steps to reach the filter housing behind the glove box.
- Open the glove box and remove any contents.
- Squeeze the sides of the glove box inward or release the damper to drop the box down fully.
- Look for the rectangular filter housing on the HVAC unit’s side (usually the right side when facing the glove box).
- Remove the filter housing cover by reversing the locking mechanism (snap or tab). A flashlight can help you see the clips.
- Carefully pull out the old filter and inspect the area for debris.
With the housing exposed, you’re ready to install a new filter or clean the area as needed.
Installing a new filter and reassembly
Now you’ll insert the new filter and re-close the housing, then restore the glove box.
- Insert the new filter with the airflow arrows pointing toward the back of the car (away from you).
- Reattach the filter housing cover until it snaps or tabs lock securely.
- Lift the glove box until it seats back against its stops, then re-engage the damper or sides so the box can open and close normally.
- Close the glove box gently and ensure it operates without binding.
- Turn on the vehicle and run the HVAC on a test setting (fresh air) to confirm proper airflow and that nothing is rubbing.
Replacement is complete when the glove box operates smoothly and the HVAC system delivers air through the cabin vents as expected.
Summary
In a 2020 Honda Civic, the cabin air filter is located behind the glove box on the passenger side. Access requires lowering the glove box, removing the filter housing cover, and replacing the filter with the correct orientation. Gather the right parts, follow the step-by-step access and installation notes, and test the system to ensure proper airflow. For reliability, consult your owner’s manual or a Honda service advisor for model-specific guidance and intervals.
