Symptoms
There is an odor, but the
color of the overall air quality
does not change.
The color of the overall air
quality is continuously red.
The concentration of fine
dust does not change.
The concentration of PM10
continues to be high.
The color of the overall air
quality differs from the level
of concentration of PM (μg/
m3).
The guide from the Ministry
of Environment is different
from the displayed overall air
quality.
The level of dust
concentration displayed
on the product is different
from that on the LG ThinQ
Application.
Nothing comes on the
screen.
Causes and Solutions
Does the color of the overall air quality not change to red or
orange?
• The color that indicates overall air quality is determined based on
the condition of the worst concentration level between the dust
concentration level and the odor concentration level. Check if the
dust concentration is worse.
• The odor sensor detects gas that causes pollution and may not
react to food odors. However, such odors are eliminated by the
deodorization filter.
Does the color not change even if it is moved to a clean room?
• If the amount of odor is more than the capacity of the product, the
display may not change.
• Remove the power plug from the outlet and reconnect after 1 minute.
Did you use a spray near the product?
• Do not use a spray near the product.
Is the product used in a closed space?
• In a closed space, the displayed air quality level may continue
unchanged.
Does the air continue to flow in from the outside to the location
where the product is installed?
• In an environment where air flows in from the outside, the
concentration level may continue to be high.
Does the color of the overall air quality match the color that
indicates odor concentration?
• The overall air quality is determined and displayed by
comprehensively evaluating the concentrations of odor and dust.
• If the odor is strong even though the concentration of dust is low, the
color of the overall air quality may change.
Is the guide from the Ministry of Environment different from the
product's dust concentration?
• The guide from the Ministry of Environment shows the average value
over a certain period of time, but the overall air quality displayed on
the product is measured and displayed in real time, so there may be
a difference.
Are you looking at the same type of dust particle?
• Check if the indication of PM1.0 (super ultra-fine dust), PM2.5 (ultra-
fine dust) and PM10 (fine dust) matches between the LG ThinQ
Application and the product.
• Due to a difference in update time between the LG ThinQ Application
and the product, the level displayed in real time may differ.
Is the display brightness set to OFF?
• To change display brightness, press and hold the Sleep Timer button
on the remote controller for 2 seconds.
