Symptom Confirmation Procedures
Air outlet has an
abnormal odor
Sensor indicator
has problem.
• Are you using the product
where there is smoke or odor?
• Are you using the product
where there is a food smell?
• Is the water in the humidifier
tray contaminated?
• Dust sensor keeps high level
always.
• Odor sensor level goes up?
• Aren’t the numerical values
of the dust sensor, odor
sensor and cleanness level
continuously moving from side
to side?
– The air cleaning function can
deteriorate in locations where
there is a lot of smoke or odor.
Ventilate the space and then
use the air purifier.
– For the food smell, it can
be penetrated to the filter,
therefore ventilate the space
and then use the air purifier.
– Clean the tray and water tank,
and then refill the water.
– Clean the dust sensor or
the filter. Due to the vapor
particles generated during
the cooking or boiling, the
numerical value of the dust
sensor can be raised.
– LG air purifier is designed to
detect polluted air, therefore
odor sensor may not react to
food odors. But deodorization
filter will remove odor.
– It is the Start-up function
which prepares the unit for
operation. During this two
minutes period, the display will
fluctuate to indicate that the
unit is sensing the air quality
in the room.
