The 2010 Hyundai Sonata has two air filters you should know about: the engine air filter in the engine compartment, and the cabin air filter behind the glove box in the passenger cabin. Replacing both keeps the engine breathing clean air and the interior air fresh.
Engine air filter location
What you’ll need
Before you begin, gather a basic set of tools (if needed) and a replacement engine air filter compatible with the 2010 Sonata. The filter is housed in a rectangular plastic box in the engine bay.
To locate and replace the engine air filter, follow these steps:
- Open the hood and locate the large rectangular air filter box on the passenger side of the engine bay, connected to the intake duct.
- Release the latches or screws securing the lid. Some models use side clips; others use visible screws that you can remove with a screwdriver.
- Lift or pry the lid off and remove the old filter, noting the correct orientation and airflow arrow on the filter.
- Insert the new filter with the arrow pointing toward the engine, reseat the lid, and re-secure the latches or screws.
- Close the hood and ensure the intake tube is properly connected and there are no gaps.
Replacing the engine air filter is typically straightforward and can be done in about 5–10 minutes with basic tools. A properly installed filter helps maintain optimal engine performance and fuel efficiency.
Cabin air filter location
What you’ll need
For the cabin air filter, you’ll need access to the area behind the glove box. Have a small flashlight handy to inspect the filter housing and ensure the new filter is oriented correctly.
To locate and replace the cabin air filter, follow these steps:
- Open the glove box and remove its contents. On several Sonata models, you may need to press the sides of the glove box inward to release the stops and allow the box to swing down.
- Look for a rectangular access panel or housing behind the glove box. Remove the panel cover to expose the cabin filter.
- Carefully pull out the old cabin filter, noting the airflow direction on the filter frame.
- Insert the new cabin filter with the arrows pointing in the direction of airflow (into the cabin, toward the HVAC unit).
- Reattach the panel, raise the glove box back into place, and ensure it closes smoothly.
Cabin air filter replacement helps maintain interior air quality, especially in dusty or polluted environments, and is generally recommended every 15,000–30,000 miles, depending on driving conditions. Always consult the owner's manual for the exact interval for your vehicle.
Maintenance notes and safety tips
- Use filters that meet or exceed the OEM specifications for the 2010 Sonata. Quality aftermarket filters from reputable brands are acceptable when properly installed.
- Install filters with the airflow arrows pointing in the correct direction to avoid reduced filtration efficiency or engine performance issues.
- If you hear a whistling noise or feel reduced airflow after replacement, recheck that the filter is seated correctly and the housing is fully closed.

Replacing both is a quick DIY task that supports engine performance and interior air quality.
