Cleaning and replacing the HEPA filter
Note
Do not operate the device without a HEPA filter
inserted!
Note
The HEPA filter cannot be washed and must be
replaced if necessary.
Note
The lifetime of the HEPA filter depends on the ambient
conditions and the application period of the device.
• The HEPA filter must be cleaned or replaced if it is very
dirty. This is brought to light e.g. by a reduced capacity
(see chapter Errors and faults).
• Make sure that the HEPA filter is installed before switching
the device on.
The operating life is approx. 1 year, depending on the degree of
air pollution.
If required, visually inspect the HEPA filter for dirt.
