9 Troubleshooting
This chapter summarizes the most common problems you could encounter with the purifier. If you are
unable to solve the problem with the information below, contact the Consumer Care Center in your
country.
Problem Possible solution
The light has been on
continuously.
The filter is full. Replace the filter and reset the purifier.
No air comes out of the air
outlet.
The purifier is not connected to the power supply. Plug the purifier
into the power supply and switch on.
The fan speed does not
change when the sleep
mode is activated.
In sleep mode, the fan speed is set to a very low level. If you want to
change the fan speed, press the button one or more times to set
the desired fan speed.
The airflow that comes
out of the air outlet is
significantly weaker than
before.
• The pre-filter is dirty. Clean the pre-filter (see ‘Clean the pre-
filter’).
• You have not removed all packaging material from the filters.
Make sure that you have removed all packaging material.
The air quality does not
improve, even though the
purifier has been operating
for a long time.
• One of the filters has not been placed in the purifier. Make sure
that all filters are properly installed in the following order, starting
with the innermost filter: 1) HEPA filter, 2) activated carbon filter,
and 3) pre-filter.
• The air quality sensor is wet. The humidity level in your room
is high and causes condensation. Make sure that the air quality
sensor is clean and dry (see ‘Clean the air quality sensor’).
The color of the air quality
light always stays the same.
• The air quality sensor is dirty. Clean the air quality sensor (see
‘Clean the air quality sensor’).
• There is not enough ventilation in the room. Open a window, to
improve the air circulation.
I need cleaner air because I
have an allergy.
You can change the air quality sensor sensitivity (see ‘Set the
sensitivity of the air quality sensor’) to make the purifier clean the
air even better.
The purifier is extra loud. • Please check if you have removed all the packaging material from
the filters.
• If the appliance is still too loud, you can change the fan speed to a
lower fan speed level.
The purifier still indicates
that I need to replace a
filter, but I already did.
Perhaps you did not press the button properly. Plug in the
purifier, press the button and press and hold the button for 2
seconds.
