POLLEN FILTER

This filter has the specific capability of com-
bining the mechanical filtering of the air with
an electrostatic effect so that the outside air
admitted to the passenger compartment is
purified and free from particles such as dust,
pollen, etc.
In addition to the above, it also effectively
reduces the concentration of pollutants.
The filtering action takes place under all
air inlet conditions and it is clearly most ef-
fective with the windows shut.
Have the conditions of the filter checked by
Alfa Romeo Authorized Services at least once
a year, preferably on the onset of summer.
If the vehicle is used mainly in polluted
or dusty areas it should be checked and if
necessary replaced, at shorter intervals.
Failure to replace the fil-
ter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the out-
lets and vents.
