(standard or optional accessory
depending on model)
This is a special active charcoal filter
which absorbs odours from the dust
collected in the dustbag. It helps,
therefore to prevent the build up of
odours.
The ACTIVE air clean filter can used in
place of the existing filter. There is no
difference in filtration level between the
ACTIVE air clean filter and the SUPER
air clean filter. See "Replacing one type
of filter with another".
Do not use aroma capsules in your
cleaner if it is fitted with this filter.
(standard or optional accessory
depending on model)
This is a HEPA class particle filter
conforming to EN 1822. It is able to
filter out very fine particles and

with a high level of hygiene.
The "HEPA filter" can be used in place
of the existing exhaust filter. See
"Replacing one type of filter with
another".
Do not use aroma capsules in your
cleaner if it is fitted with this filter.
