Humidifying Air Purifier 21

Humidity indicator lamp
(For reference only)
This lamp indicates the room humidity detected by humidity
sensor.
In case running the unit just to air purifying operation, the
lamp also indicates the humidity level.
Odor sensor lamp
Odor sensor detects the changes in airborne odors. The level of odors is indicated by
odor sensor lamp on 3 colors: green, orange and red.
• When the lamp is lit on green, the air is clean.
In the following cases, the lamp is lit on green for the initial 1 minute. This state is regarded as the
sensitivity reference value of the odor sensor.
(1) Operation directly after setting the front panel.
(2) Operation directly after setting the power plug.
(3) In case the operation is started again.
If the odor level remains constant without intensifying or weakening, the sensor may not detect even
strong odors.
The odor sensor may not detect the type of odors other than ammonia, such as pet odors, garlic, etc.
Different people have different sensitivity to odors so you might notice an odor even though
the lamp is green. If bothered by odors, set manual airflow control and run the unit at a
higher airflow rate.
