Problem
The appliance is extra
loud.
The appliance still
indicates that I need
to replace a filter, but I
already did.
The appliance stops
operating, although the
power-on light is still on.

Possible solution
You haven't removed all packaging material from the filters. Make sure that
you have removed all packaging material.
Perhaps you did not press the filter reset button properly. Plug in the
appliance, press and hold the on/off button and press the filter reset button
with a flat tool.
The built in quality sensor has determined that the air quality is good and
that the air does not need to be cleaned anymore. When the air quality
deteriorates, the appliance starts running at a low fan speed and noise level
so that the energy consumption is minimised.
