Problem
Possible Cause
Solutions
There has been
no change in
micro dust
concentration.
• Sensor may be dirty or blocked
by foreign material.
• Air purifier may be in enclosed
area.
• See instructions for cleaning sensor.
• Indoor air quality may stay the same in
an enclosed area.
The fine dust
concentration
value keeps
showing high.
• Air purifier installed in area
with constant influx of outside
air.
• Levels can remain high in areas where
there is a constant influx of outside air.
Air quality light
remains violet/
pink while PM
levels show
moderate/
unhealthy.
• Air quality issue is from odor.
• The air quality indicator is an overall
evaluation based on odor and dust. If
an odor is strong while PM levels are
moderate, the light may remain on
violet/pink.
The filter
produces odors.
• The deodorizing filter has
become dirty.
• The air purifier is being used
instead of a vent hood while
cooking.
• Replace the filter. Filter life-expectancy
can vary based on usage environment.
• Filter life can be greatly reduced if
the air purifier is used while cooking
strong-smelling or oily food. Do not use
the product in place of a vent hood.
Ventilate the area during cooking to
remove strong odors and oily splatter,
then use the air purifier to eliminate any
remaining odors.
I can't connect
to the product
in the LG Smart
ThinQ app.
• The power plug is unplugged
from the outlet.
• Plug in the power cord of the product.

I can't register
the product in
the LG Smart

• The product is too far away
from the wireless router.
• Move the wireless router near the
product.
• Your wireless router may be
not working properly.
• Some carriers provide routers that are
available to their members only. If you
have an outdated model, contact your
carrier to have it replaced with a newer
one.
The dust
concentration
levels are
different
between the
product and the
LG Smart ThinQ
app.
• You looked at the different dust
particle.
• Make sure that the levels of the
super ultra-fine/ultra-fine/fine dust are
displayed consistently between the LG
Smart ThinQ app and your product.
• The difference in the values could be
caused by the difference in update time
between the LG Smart ThinQ app and
the product.
