Understand the healthy air
protect alert
The healthy air protect alert gives you a timely
warning when the water tank needs refilling.
When the water in the tank starts getting low, a
red indicator on the control panel starts blinking
to tell you that it is time to refill the tank.
Understand the healthy air
protect lock
The healthy air protect lock always ensures that
your humidifier does not work without water
in the tank. When the water tank is empty and
needs to be refilled, the healthy air protect lock
shuts off the humidifier and a red indicator
lights up. When you refill the water tank
properly, the humidifier is turned on again.
