Sub-Zero Pure Air Icon Flashing



Pure Air Information

The Pure Air icon flashes when the air cartridge needs to be replaced.

  • This occurs after 365 days of use while the unit is on and the air filter is on.
  • This occurs earlier if the bulb inside the cartridge burns out.

No harm will be done to the Sub-Zero unit if the air filter is not replaced or not used.
