Step-by-Step Instructions

Follow these steps carefully

1

Empty the glove box

Note: verified for 2017-2025 (KF generation); the redesigned 2026 model's filter location is unconfirmed - check your owner's manual. Open the passenger glove box and remove everything from it.

2

Disconnect the damper arm

The damper arm on the right side wall of the glove box slows its fall. Slide it to the right to disconnect it.

3

Drop the glove box

Squeeze the sides of the glove box inward to release the stop tabs, then let it swing down fully.

4

Open the filter access door

Behind it you will see the rectangular filter access door in the HVAC housing. Release it (lift/pull the hook or tab) and remove the door.

5

Remove the old filter

Slide the old filter out, noting which way the airflow arrow points.

6

Install the new filter

Slide the new filter in with the airflow arrow pointing the same direction as the old one.

7

Reassemble

Reinstall the access door, lift the glove box back up, and reconnect the damper arm on the right side.

All Done!

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

⚠️ Common Mistakes to Avoid

  • • Forgetting to turn off the vehicle before starting the replacement process.
  • • Installing the new filter in the wrong orientation, which can affect airflow and filtration efficiency.
  • • Not cleaning the filter compartment before installing the new filter, leading to potential debris contamination.
