The cabin air filter (commonly referred to as the AC filter) in most Honda Accords is located behind the front passenger glove box. The engine air filter, which is separate from the cabin filter, sits in the engine bay on the driver's side. This guide covers both locations and how to replace them.
Cabin air filter location and replacement
This list walks you through locating and replacing the cabin air filter, which cleans the air entering the HVAC system.
- Open the passenger-side glove box and empty its contents.
- Gently press in on the sides of the glove box to release the stops and drop the door down, exposing the HVAC behind it.
- Look for the rectangular cabin air filter housing. Remove the access panel or cover by releasing its latches or screws.
- Remove the old filter and note the orientation of the arrows that indicate air flow. Replace with a new filter oriented in the same direction as indicated.
- Clean any debris from the housing, insert the new filter fully, and reattach the access panel.
- Lift the glove box back into place and ensure it closes securely.
Replacing the cabin air filter is typically recommended every 15,000 to 30,000 miles, or more often in dusty environments or heavy city driving. If you notice reduced airflow, odd smells, or increased noise from the HVAC system, inspect or replace the filter sooner.
Engine air filter location and replacement
This list explains how to locate and replace the engine air filter, which protects the engine from debris and helps maintain performance and fuel efficiency.
- Park the car on a flat surface and set the parking brake. Open the hood and locate the engine air filter housing on the driver’s side of the engine bay near the front.
- Unclip or unscrew the housing lid to access the filter. Remove the lid and set it aside.
- Carefully lift or slide out the old engine air filter. Check the housing for debris and wipe it clean if needed.
- Slide a new filter into the housing in the same orientation as the old one, ensuring a snug fit with no gaps.
- Reattach the housing lid and secure any clips or screws. Lower the hood and test the engine start to confirm there are no unusual noises.
Engine air filters are typically replaced every 30,000 to 45,000 miles, though more frequent changes may be required in dusty areas or for older engines. Always verify the correct filter type and orientation for your specific model year in the owner's manual.
Tips and what to check if you’re unsure
If you’re uncertain about your model year’s layout, consult the Honda Accord owner's manual or use the car’s model-year-specific maintenance guide. You can also search online for a quick video or guide tailored to your exact year and trim to confirm the filter locations before starting.
Summary
For most Honda Accords, the cabin air filter sits behind the front passenger glove box and the engine air filter is in the engine bay on the driver's side. Replacing both filters involves exposing the respective housings, removing the old filters, and inserting new ones with the correct orientation. Regular replacement helps maintain cabin air quality and engine efficiency.
