Microfilter/activated-charcoal filter
The built-in microfilter removes dust and
pollen from the incoming air. The activated-
charcoal filter provides additional protec-
tion by filtering gaseous pollutants from the
outside air. Your BMW center replaces this
combined filter as a standard part of your
scheduled maintenance. A substantial
reduction in airflow indicates that the filter
needs to be replaced earlier.
