Model X has an air filter that prevents pollen, industrial fallout, road dust, and other particles from entering the cabin through the vents. Tesla recommends replacing these filters every 2 years (every year in China). Cabin filters can be purchased at the Tesla Shop (or https://shop.tesla.cn/ for China).

To replace the cabin filter:

1. Turn off the climate control system.
2. Move the front passenger seat fully rearwards.
3. Slowly and gently pull down the footwell cover to release the magnets, then disconnect the electrical harness on the right side of the cover. Set the footwell cover aside.
4. Squeeze the cabin filter door lock to release it, and then remove and set the door aside.
5. Note the direction of air flow printed on the cabin filter. The arrows on the filter should face toward the rear of the vehicle.
6. Slide the filter out of the HVAC module.
7. Ensuring that the arrows on the new filter face toward the rear of the vehicle, insert the new cabin filter into the HVAC module.
8. Slide the cabin filter door onto the HVAC module, and then push the door to lock it.
   Note

   Ensure the lock is fully engaged and the door is sealed shut.
9. Position the front passenger footwell cover on the vehicle and connect the electrical harness to the cover.
10. Install the front passenger footwell cover, making sure the magnets (x3) are locked into position.
11. Move the front passenger seat back to its original position.
