Possible solution
The surface of the filter is dirty.
Clean the surface of the filter
( Chapter 5 "Cleaning and
maintenance", Page 47).
• Check if the plastic cover is
removed from the filter.
• The filter has not been placed in
the appliance. Make sure that
the filter is properly installed.
• The particle sensor is wet. The
humidity level in the room is
high and causes condensation.
Make sure that the particle
sensor is clean and dry
( Chapter 5 "Cleaning and
maintenance", Page 47).
• Room size is large or the
outdoor air quality is poor. For
optimum purification
performance, close the doors
and windows when operating
the air purifier.
• There are indoor pollutants.
For example, smoking,
cooking, incense, perfume or
alcohol.
• Filter has reached the end of
life. Replace the filter with a
new one.
The particle sensor is dirty. Clean
the particle sensor ( Chapter 5
"Cleaning and maintenance",
Page 47). If the air quality is good,
the light should be blue at all times.
The first few times using the
appliance, it may produce a plastic
smell. This is normal. However, if
the appliance produces a burnt
smell even after removing the
filter, contact support
services.The filter may produce
smell after being used for a while
because of the absorption of
indoor gases. It is recommended
to reactivate the carbon filter by
putting it in direct sunlight. If the
smell persists, replace the filter.
• The appliance is operating at a
high speed, as set in manual
mode.

outlet, it may also cause an
unusual loud sound.
