Replacing the exhaust filter
Depending on the model, the vacuum
cleaner will be equipped with one of the
following exhaust filters:
a "SUPER air clean" filter
b "ACTIVE air clean" filter
c "ACTIVE HEPA" filter
"SUPER air clean" filter
A "SUPER air clean" filter is supplied
with every box of Miele dustbags. It
should be replaced each time a new
box of bags is started.
"ACTIVE air clean" or the "ACTIVE
HEPA" filter
An "ACTIVE air clean" or "ACTIVE
HEPA" filter should be changed
approximatetly once a year. Change
the filter sooner if it is obviously soiled
or no longer effective.
It is helpful to make a note of the date
directly on the filter as a reminder for
when to next change it. See "Optional
Accessories" for filter descriptions.
