Air Filter Operation

Core Issue:

  • The air purification icon, pure air icon, or air filter icon is missing, on, displayed, shown, flashing, blinking.
  • How do you turn the PURE AIR on or off?
  • Does the air purification cartridge eliminate all odors in the refrigerator?
  • How to turn on air purification feature

Answer:

The "PURE AIR" key on the unit control panel activates or deactivates the air purification system.

  • The air purification icon looks similar to a sheet of paper with 3 wavy lines going through it when the air filter is on.
    • If the icon is not present, the air purification system is turned off.
    • If the icon is present and not flashing, the air purification system is turned on.
    • If the icon is present and flashing, the air purification cartridge needs to be replaced.
  • When activated, the UV light in the filter cartridge and the fan motor under the cartridge are energized 100% of the time unless the refrigerator door is opened or the unit is in Showroom mode.
  • Replacement air purification cartridges are available for purchase through Sub-Zero’s Accessory Store or through a Factory Certified Parts Distributor.
  • If the filter fails prematurely, see Cartridge Life for more information.
  • Refer to Built-In Air Filter Part Numbers for additional information.
