When to change the exhaust
filter
Depending on model, your vacuum
cleaner will be fitted as standard with
one of the following exhaust filters:
a Air Clean filter
Replace this filter every time you start a
new packet of Miele dustbags. An Air
Clean exhaust filter is supplied with
every packet of Miele dustbags.
b Active Air Clean filter (black)
c Active HEPA filter (blue)
These types of filter need to be
changed approx. once a year. Make a
note of the date on the filter.
Exhaust filter change indicator
Certain models are fitted with an
exhaust filter change indicator (reset
button) to show you when to change
your Active Air Clean b or Active HEPA
c filter.
The indicator lights up after approx. 50
hours of operation, which is equivalent
to about a year of average use. The
vacuum cleaner can still be used with
the exhaust filter indicator lit up.
However, the suction power will be
reduced as will the effectiveness of the
filter if it is not replaced in good time.
The filter change indicator light is
irrelevant if an Air Clean filter a is fitted,
as long as it is replaced every time a
new packet of Miele dustbags is
started. The indicator light will go out
when the reset button is pressed.
