Doesn't the color change
even if it is moved to a
clean room?
Did you use a spray near
the product?
is the
(Lock) turned
on on the status display
panel?
is there a foreign
substance on the sensor?
is the product used in a
closed space?
Does the air continue to
flow in from the outside
to the location where the
product is installed?
Does the color of the
overall air quality match
the color that indicates
the odour concentration?
is the operation mode set
to Smart mode or Speed
is set to Auto mode?
Solution
• If the amount of the odour is
more than the capacity of the
product, the display may not
change.
• Clean the sensor area.
• remove the power plug from
the outlet and reconnect it one
minute later.
• Do not use a spray near the
product.
• Press and hold the Sleep
Timer button for 3 sec. or
longer to disable the lock
function.
• Clean the PM1.0 sensor.
• In a closed space, the
cleanliness level may continue
to stay the same without
change.
• In an environment where
outside air is supplied
continuously, the
concentration may continue to
remain high.
• The overall air quality
is displayed by
evaluating the odour and
particles concentration
comprehensively.
• even if the particles
concentration is low, if the
odour is strong, the overall air
quality color may not match
the particles concentration
value.
• It may make a sudden noise
as it automatically adjusts the
air flow depending on indoor
air quality.
