Maintenance and care

When to change the exhaust filter

Depending on the model, your vacuum cleaner will be fitted as standard with one of the following exhaust filters:

a Air Clean filter SF-AC 30,

Replace this filter every time you start a new packet of Miele dustbags. An Air Clean exhaust filter and a dust compartment filter are supplied with every packet of Miele dustbags.

b Active Air Clean SF-AAC 50 (black) c Active HEPA SF-AH 50 (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 control) to show 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. You can continue vacuuming when the light comes on. 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 being used, 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.
