Optional accessories
Active Air Clean filter
(standard on some models)
A special active charcoal filter which
absorbs odors from dust in the
dustbag, helping to prevent odors.
The "Active Air Clean filter" can be
inserted in place of the "Air Clean filter".
There is no difference in the fine dust
performance of the "Active Air Clean"
and the "Air Clean" filter.
HEPA Filter
(standard on some models)
The "HEPA" filter combines activated
charcoal and HEPA filtration in one. The
active charcoal layer absorbs odors
from the dust collected in the dustbag.
Vacuum cleaners equipped with this
exhaust filter are particularly suitable for
allergy sufferers and those concerned
with a high level of hygiene because of
its ability to trap respirable particles
and allergens. The "HEPA filter" can be
inserted instead of the existing exhaust
filter.
Filter frame
The filter frame is needed if you would
like to exchange a Air Clean filter with
an Active Air Clean or HEPA filter, see
"Exchanging exhaust filters".
