Filter change
The service life of the filter unit is heavily
dependent on the operating conditions (room air
quality, contaminated atmosphere, high air
humidity).
We recommend a thorough cleaning every 2
weeks (see chapter Cleaning).
Use the “Filter change” indicator lights as a guide
for the interval between filter replacements. If this
lights up, or if the filter is older than 8 months, the
filter unit must be replaced. To do so, proceed as
follows:
1.
Switch the unit off and pull out the power
plug.

2.
Place the top of the air purifier on a soft sur-
face (to avoid scratching the surface). The
sealing cover of the filter unit is on the under-
side of the unit. Turn the sealing cover anti-
clockwise so that the marking of the lock
symbol points to “open”.

3.
Remove the sealing cap and carefully
remove the filter unit. Proceed carefully so as
not to distribute the dirt particles picked up by
the filter in the room. We recommend dis-
posing of the used filter unit in an air-tight
bag!

4.
Remove the packaging material of the
replacement filter.
5.
Put the filter unit back in and put the sealing
cover back on. Ensure that the marking is
facing you.

6.
Turn the sealing cover clockwise until the
lock symbol points to “closed”. An audible
“click” can be heard.
