Step-by-Step Instructions

Follow these steps carefully

1

Prepare the vehicle and locate the filter

Park the 2018-2024 Hyundai Sonata safely, switch the ignition off, and locate the cabin air filter access behind or below the glovebox. Confirm the replacement filter matches the old filter before disassembly.

2

Open the glovebox access

Empty the glovebox in the 2018-2024 Hyundai Sonata. Release the side stops and disconnect the damper strap only as needed, supporting the door so it does not drop against the trim.

3

Remove the old cabin filter

Remove the access cover and slide the cabin filter out of the 2018-2024 Hyundai Sonata. Note the airflow arrow and inspect the old element for leaves, dust, moisture, or mold before discarding it.

4

Clean and install the new filter

Wipe or vacuum the filter tray in the 2018-2024 Hyundai Sonata without pushing debris into the blower. Install the new cabin air filter with its airflow arrow in the same direction and its edges fully seated.

5

Reassemble and test HVAC operation

Refit the cover, reconnect the glovebox damper, and engage every stop on the 2018-2024 Hyundai Sonata. Run the blower through several speeds and verify there is no rubbing, air leak, or warning from loose trim.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Installing the filter with the airflow arrow reversed
  • • Failing to fully seat the filter perimeter in its guides
  • • Leaving leaves or dust inside the filter housing
  • • Forcing the glovebox damper, stops, or cover clips
