Replacing the cabin air filter on a 2019 Honda Accord is a quick DIY task that typically takes about 5–10 minutes. You’ll access the filter behind the glove box, swap in a fresh filter, and reassemble.
The cabin air filter helps remove dust, pollen, and other particles from the air entering the car’s heating and air conditioning system. In the 2019 Accord, the filter sits in a rectangular housing behind the glove box. Access involves lowering the glove box, releasing the housing cover, and replacing the filter with the correct orientation before reseating the housing and glove box.
What you’ll need
Before you begin, gather these items to make the job quick and clean.
- Replacement cabin air filter for your 2019 Honda Accord (OEM or equivalent)
- Flashlight or a phone light to see inside the housing
- Clean rag or microfiber cloth
- Gloves (optional but helpful)
With these items ready, you’re prepared to start replacing the filter.
Steps to replace the cabin air filter
Follow these steps to access the filter and install a new one in your Accord.
- Park the car and turn off the engine. Set the parking brake for safety.
- Open the glove box and remove its contents to create working space.
- Gently press inward on the sides of the glove box to release the stops and let the glove box panel drop down. If your model uses a damper, let it swing down slowly to gain access to the filter housing.
- Behind the glove box, locate the rectangular cabin air filter housing and release the cover by unhooking its clips or tabs.
- Slide out the old cabin air filter and note its orientation. If it’s very dirty or damp, replace it with a new one.
- Wipe the inside of the housing with a damp rag to remove dust or debris, then let it dry before installing the new filter.
- Insert the new filter with the arrows pointing in the direction of airflow into the cabin (toward the HVAC unit). Make sure it sits flat in its frame and isn’t obstructed by any debris.
- Reattach the housing cover and secure the clips. Lift the glove box back into place and close it firmly.
Filter orientation tip
Make sure the new filter’s orientation follows the airflow arrows toward the HVAC unit. The arrows indicate the direction air should move as it passes through the filter.
When finished, run the climate control for a few minutes to confirm proper airflow and listen for any unusual noises. If you notice odors or decreased airflow, consider replacing the filter sooner in the future.
Tips and considerations
Regular replacement helps maintain cabin air quality and HVAC efficiency. Honda generally recommends checking or replacing the cabin air filter roughly every 15,000–30,000 miles, depending on driving conditions and environment. If you frequently drive on dusty roads or have allergy concerns, you may want to replace it more often.
Summary
Replacing the cabin air filter on a 2019 Honda Accord is a straightforward maintenance task that most drivers can complete in about 5–10 minutes. By accessing the filter behind the glove box, removing the old filter, installing a correctly oriented new one, and reseating the housing and glove box, you can improve interior air quality and HVAC performance without specialized tools. Always verify proper orientation and test the system after replacement.
