Answer:
Pure Air Icon Flashing
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.
