how to reset air purifier icon on sub zero refrigerator

To reset the air purifier icon on a Sub-Zero refrigerator, follow these steps:
1. Open the refrigerator door and locate the control panel, usually inside the fridge compartment or on the front grille.
2. Look for the "Air Purifier" or "Pure Air Filter" button. Press and hold it for approximately 3-5 seconds.
3. Continue holding the button until the air purifier indicator light or message on the display resets.
4. Release the button after the reset is complete. The air purifier icon should now show that it is ready for a new filter or return to its initial state.
5. For optimal performance, replace the air purifier filter every six months or as recommended by the manufacturer.
If you face difficulties or the indicator doesn't reset, refer to the refrigerator's user manual or contact Sub-Zero customer support for further assistance.
