Maintenance and care When should I change the exhaust filter? Depending on the model, your vacuum cleaner will use one of the following standard exhaust filters: a Air Clean Change the exhaust filter each time you open a new box of Miele filter bags. A new Air Clean exhaust filter is included in every box of Miele filter bags. b Active Air Clean SF-AAC 50 (black) c Active HEPA SF-AH 50 (blue) Replace this exhaust filter after approx. one year. You can write down the date on the exhaust filter. Filter change indicator Certain models are equipped with a filter change indicator to show you when to change the Active Air Clean b or Active HEPA c filter. The indicator and the reset button will light after approximately 50 hours of operation, which is equivalent to an average of one year of use. Once the indicator light comes on, you can still continue to use the vacuum cleaner. However, the filter performance and suction power will be reduced. If you use the Air Clean a exhaust filter instead, lighting of the filter change indicator and reset button can be disregarded as you simply replace the Air Clean filter every time you open a new box of Miele filter bags. The indicator lights turn off when the reset button is pressed. 28
