dust sensors
It may reduce the sensitivity of the sensors.
Safety Precautions
Do not operate with the filter detached
Refrain from placing any object on the unit and blocking
the air inlet and outlet
Do not use in locations near cooking appliances
Refrain from moving (changing the orientation or lifting the unit, etc.) during operation
Ventilate closed rooms occasionally
Do not use near television or radio
The purifier does not have
a ventilation effect (removal of carbon monoxide
and other contaminants).
* The purifier cannot remove harmful substances in cigarettes (carbon
monoxide, etc.).
Moving the unit while in operation may cause the fan
to hit the inner case, generate noise, pull and disconnect the power cord, and cause unit failure.

broadcasts.
Please them at least 2m apart
from each other.
The same applies for cordless phones and wireless microphones.
Air Cleaner Deodorizing Performance
It may cause deformation and discoloration due to heat or oily smoke,
unit damage or fire.
Place the purifier and the cooking appliance at least 1m apart from each other.
Cautions on Use
Doing so may cause unit failure
and injury.
Air Cleaner Deodorizing Performance
 The filter of the air purifier does not remove all odors at once, but rather circulates the air in the room, removing odors gradually.
 The filter is disposable. The deodorizing performance of the filter decreases with use.
 When the odor emitted from the vent becomes bothersome, clean the filter.
(P.E-23)
 When the filter has absorbed strong odors or has been continually used in an odorous room, the odor components remain in the filter and unit, causing the odor to be emitted from the vent.
If this happens, you can decrease the amount of odor that remains in the unit by continuing to operate the
purifier while ventilating the room.
 The dust and other contaminants attached to the filter and unit also contain odor components.
Periodically clean the filter and unit so that odor is less likely to be emitted from the vent.
 If the odor emitted from the vent remains bothersome after cleaning, replace the filter.

Note
 When the unit is placed in a location where contamination is difficult to detect, or when the sensor needs cleaning,
the display may not change. (P.E-24)
 While operating in PM2.5 sensing, the air sensor display lights up and then blinks slowly.
Useful Features
Odor Sensor
Dust Sensor
 The dust sensor is capable of sensing dust in the air such as cigarette smoke,
house dust, pollen, etc.
The dust sensor may fail to sense dust stirred up when you lay out or put away bedding, which contains significantly fewer contaminants than cigarette smoke, etc. In
such a case, the air sensor display may appear to be different from the apparent
dust in the air.
 The dust sensor may not function properly if the sensor is dirty.
Carry out periodical cleaning of the dust sensor and the parts around it. (P.E-24)
Odor Sensor
Cover is removed
Memory Function / Sensors / Auto Detection
 The sensor detects odors in the air such as cigarette smoke or pet odors.
Even if you think the air is clean, the unit may continue the operation if the odor sensor
detects any gas component that has not been removed by the filter.
Also, any of the following may be detected by the odor sensor.
· Combustion gases from heating appliances during use, alcohol, odor of perfumes or
cosmetics used in beauty parlors or aesthetic salons, sprays, vapors, abrupt temperature changes, etc.

Memory Function / Sensors / Auto Detection (Continued)
Auto Detection
 The air purifier performs automatic operation by detecting room air contamination using the “Odor Sensor” and “Dust
Sensor”.
During the first 3 minutes after the power is turned on, the unit will check the air condition of the room.
 The purifier operates even while it checks the air condition of the room.
During this time, the “Air Sensor” flashes green.
 After checking the air condition, the “Air Sensor” will display the room air contamination using the “Odor Sensor”
and the “Dust Sensor”.
 If you plug in the power cord in an environment containing contaminated air, the sensitivity of the sensor may be
reduced.
To clean the air of the room, operate in “High” or “Max”. Or open a window and unplug the power cord from the AC
outlet when ambient air is clean and plug it back in after 10 seconds.
Adjusting Sensory Sensitivity Setting
 Sensitivity of the “Odor Sensor” and “Dust Sensor” which performs automatic switching of airflow rate can be adjusted in 3-step fashion.
You can adjust the sensor sensitivity setting as desired.
 The “Odor Sensor” and “Dust Sensor” are similarly adjusted.
