Filter saturation check

The air exchange rate is based on the room size (air volume in the room) and how fre-
quently this air volume is filtered per unit of time.
The air exchange rate is set to 6 air changes in the factory default settings and after a filter
replacement (with the appropriate room size, where the maximum room dimensions must
not exceed the size equivalent to the nominal capacity). Due to the constant filtering of the
room air via the filter, the air exchange rate decreases over time. The retention rate of the
filter is not reduced. A reduced air exchange rate is identified in the air purifier via a differ-
ential pressure measurement. If the air exchange rate drops below 4 air changes, this is
signalled by the red LED lighting up and a warning message appearing.
The saturation of the filter must be checked once a week by setting the fan setting to
100 % for at least 20 seconds in
If the red LED lights up and the fault message
when the fan setting is set to 100 %, the filter is saturated.
In order to maintain the air exchange rate of 6 air changes when the filter is saturated, the
fan setting must be increased. The table below shows how much the fan setting needs to
be increased when the filter is saturated. The air purifier must be in
purpose. The filter is expected to reach saturation after approx. 1–2 years (depending on
site conditions, individual particle ingress and regular cleaning of the pre-filters). Miele
therefore recommends regular maintenance by the Miele Customer Service Department.
