Optional accessories
ActiveAirClean Plus filter
A special active charcoal filter which
absorbs odors from the dust collected
in the dustbag. The "ActiveAirClean
Plus" filter can be used in place of the
"SUPER air clean" filter. There is no
difference in the fine dust performance
of the "ActiveAirClean Plus" and the
"SUPER air clean" filter.
Active HEPA Plus Filter
The "Active HEPA Plus" 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.
