Steps to Verify Issue:
Air purification filters are ready to be replaced whenever the indicator light begins to flash.
- A steady indicator light is normal.
- There is no harm to the Sub-Zero unit if the air filter is not replaced or not used.
All Sub-Zero models with an air purification system use the same kind of air purification cartridge.
- Replacement air purification cartridges are available for purchase through Sub-Zero’s Accessory Store or through a Factory Certified Parts Distributor.
For other product lines and general air filter information, refer to Air Purification Filter Replacement.
The “Change Air Purifier” message appears on the display when the air filter cartridge needs to be replaced.
- Touch “Snooze” to delay the reminder for 24 hours or until cartridge can be replaced.
- Touch “Refresh” to reset the life indicator to 100% once the cartridge is replaced.
To replace the air purification cartridge:
- Find the air filter access door cover on the inside back wall of the refrigerator, usually between the top two shelves depending on shelf placement. It may be necessary to remove a shelf if it is positioned in front of the access door.
- To access the air purification cartridge, hold the outside cover from the bottom and rotate upward. The cartridge will be inside as shown.
- Hold the black cover from the top and rotate downward. The cartridge will pop out and can be removed.
- Remove the new cartridge from packaging and insert with connector pointing downward.
- The Sub-Zero logo does not have to be facing out. The cartridge may be installed with the logo facing inside the unit.
- Once in position, close the black cover. Then rotate the outside cover downward until it closes against the back wall.
- Once the cartridge has been replaced, follow instructions on the control panel. The cartridge life cycle will reset for approximately one year.
