4 Using the
humidifier
Understand the humidity
indication
The humidifier is equipped with a built-in
humidity sensor. For HU4802, you can set the
target humidity level at 40%RH, 50%RH and
60%RH. The color of the humidity indicator
light shows whether the set target is reached
or not. For HU4803, the actual humidity level
is displayed on the center of the control panel
from 20%RH to 95%RH.

Note
• A comfortable humidity level is from 40RH% to 60RH%.
• The accuracy of the humidity indication is
approximately ±10%.
• It takes some time to measure the humidity level in
the room.

Note
• The humidity indicator light is only available on HU4802.
• The humidifier is equipped with built-in humidity sensor.
When the desired humidity level is reached, the color
of the humidity indicator light is in blue. When the
humidity level is not reached, the color of the humidity
indicator light becomes red.
Understand the healthy air
protect alert and lock
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. It blinks
for 30 minutes. After that, the indicator remains on
before the water tank is refilled with water.
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 after 30 minutes and a
red indicator lights up. When you refill the water
tank properly, the humidifier is turned on again.
Note
• In sleep mode, the red indicator does not blink, it turns
on when the water level is low.
