Maintenance and care
Exchanging exhaust filters
Depending on the model, your vacuum cleaner will use one of the following standard exhaust filters:
a Air Clean
b Active Air Clean (black)
c Active HEPA (blue)
If you wish, you can use one of the alternative filters instead of the standard filter supplied with your appliance. Each filter offers different characteristics (see section "Optional accessories").
Important
1.If you replace exhaust filter a with exhaust filter b or c, you must be sure to remove the filter frame before inserting the new filter type.
2.If you replace exhaust filter b or c with exhaust filter a, be sure to place the new filter in a filter frame *.
Do not use more than one filter at a time
* Filter frame - see "Optional accessories"
Some models are equipped with an exhaust filter reset button. This button indicates when to change the Active Air Clean filter and the Active HEPA filter. If an Air Clean filter is used, the reset button can be disregarded. The Air Clean filter should be changed whenever a new box of Miele dustbags is opened. The indicator goes out when the reset button is pressed.
