how to reset sub zero air purification cartridge

Sub-Zero air purification cartridges do not typically have a reset function. Instead, they have a replacement indicator that alerts you when it's time to replace the cartridge. When the indicator light turns on, it indicates that the cartridge's lifespan is over and you need to replace it.
To reset the indicator after installing a new air purification cartridge, follow these steps:
1. Open the refrigerator door.
2. Press the "Filter Reset" or "Air Purification Reset" button on the control panel for about 3-5 seconds.
3. The indicator light should turn off or reset, confirming that the cartridge has been replaced.
If your refrigerator doesn't have a reset button or the indicator doesn't reset as expected, refer to your refrigerator's manual or contact Sub-Zero customer support for assistance.
