Cleaning the pre-filter
The pre-filter consists of a nylon fabric that pre-
vents coarse particles such as hair and dust flakes
from further entering the following filters. The pre-
filter can either be cleaned carefully with a vacuum
cleaner or with lukewarm water.

Heavier contamination may be remedied by rinsing
the filter in a lukewarm (max. 40°C) soap solution.
Finally, always rinse the filter carefully with clear
water and allow to dry.

Before refitting the dust filter, ensure that its fully
dry and that no damage has been sustained.
Replacing the after-filters
The filter foam mat, the activated carbon granulate
cassette and the HEPA filter cannot be regener-
ated. After removal, the filters must be disposed of
and replaced with new original filters. Handle used
filters with care and dispose of them as soon as
possible to prevent particles from separating from
the filter media and getting back into the room air.
If the used filters cannot be disposed of immedi-
ately, it is advisable to store the filters in airtight
sealed packaging until final disposal.
Do not bend, fold or knock out the used filters
on any other object. The particles released in
the process can pose a health risk if inhaled.
As a rule, the used filters can be disposed of in
household waste. If harmful substances have
been filtered with the filters, it may be neces-
sary to dispose of the filters as hazardous
waste. If in doubt, enquire about local regula-
tions and laws.
Cleaning the units
The units should be cleaned regularly both outside
and inside the filter housing. Use gentle cleaning
agents and clean the unit with a soft cloth. How
often the unit needs to be cleaned depends heavily
on the usage pattern and should always be
checked.
