Size range and filter types

How to replace the cabin air filter
Replacing the cabin air filter in a 2012 Civic is a straightforward maintenance task. The process generally involves accessing the filter housing behind or near the glove box and installing the new filter with the correct orientation.
- Turn off the car and locate the glove box. Empty it and support it so it doesn’t drop when opened fully.
- Open and/or remove the glove box damper if your model uses one, then lower the glove box to access the filter housing behind it.
- Open the filter housing cover to expose the old filter.
- Carefully remove the old filter, noting the direction of the airflow arrows on the filter framing.
- Clean out dust or debris from the housing if present.
- Insert the new filter with the arrows pointing in the direction of airflow, ensuring it sits flat in the housing.
- Replace the housing cover and reattach the glove box or damper, then close the glove box securely.
- Turn on the climate control to verify air is flowing normally from the vents.
Replacement duration is typically a short service task, and you should consult the owner’s manual or a repair guide for any model-specific steps. Verify the recommended replacement interval in your manual, as it can vary by trim and driving conditions.
