Confirmation
• Are you using the product where there is smoke or
odor?
• Are you using the product where there is a food
smell?
• Did you completely dry the washable HEPA filter?
• 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?
Procedures
• 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.
• If you use the washable filter without completely drying
it, it can generate a weird smell. Therefore dry the filter
completely before using it again.
• 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 ther room.
