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