The cabin air filter in a 2020 Honda Civic is located behind the glove box on the passenger side. Access it by dropping the glove box and removing the filter housing cover.
Keeping the cabin air filter in good condition helps maintain air quality inside the car and HVAC efficiency. Honda Civics from this generation typically require filter replacement every 15,000 miles or about once a year, though driving in dusty or urban environments may shorten that interval. Replacing it is a straightforward DIY task that requires no special tools on most trims.
Location and access
The filter sits in a rectangular housing behind the glove box. To reach it, open the glove box, release its stoppers to let the box drop down, and look for the filter housing mounted to the HVAC intake. A small door or cover on the housing can be removed to access the filter.
How to replace the cabin air filter
Follow these steps to locate and replace the cabin air filter in your 2020 Civic.
- Open the passenger-side glove box and remove any items.
- Squeeze the sides of the glove box inward to release the built-in stops and let the box drop down fully.
- Look behind the glove box for the rectangular filter housing and peel off or unclip the housing cover to expose the filter.
- Remove the old cabin air filter and note its orientation (many filters have an arrow indicating airflow).
- Insert the new filter with the arrows pointing toward the blower motor (into the cabin). Ensure it sits flat and fully seated in the housing.
- Replace the housing cover and push the glove box back up until the stops engage, then close the glove box door.
- Start the car and run the climate control for a few minutes to confirm airflow and that the filter is correctly seated.
Taking these steps will restore proper airflow and filtration in the Civic’s cabin without needing a professional service visit.
