1 Open the glove box. 2. Push on both sides of the top of the glove box to allow the stoppers on the top two sides to pass the frame of the glove box. Allow the glove box to open fully, it will swing all the way open. You will now see the filter chamber. 3. Open the door by pressing the little tabs in and remove the filter. Done! Just close it back up. Honda charges $99 to do this.
