Maintenance and care
When to change the exhaust filter
Your model will have either the:
a Air Clean
An Air Clean filter is supplied with every box of Miele dustbags and should be changed when starting a new box of dustbags.
b Active Air Clean
c Active HEPA
These filters should be changed approximately once a year. Change the filter sooner if it is obviously soiled or no longer effective. Make a note of the date on the filter. See "Optional Accessories" for descriptions of these two filters.
