The dust/pollen filter should be checked

over at least once a year by Alfa Romeo

Authorized Services, preferably at the be-

ginning of summer.

If the vehicle is habitually driven in pol-

luted areas or on dusty roads the system

should be checked and if necessary

changed more often.

If the filter is not re-

placed the efficiency of

the climate control sys-

tem may be seriously compro-

mised.

ACTIVATED CARBON

DUST/POLLEN AIR FILTER

The filter has the specific capability to

combine the mechanical air filtering func-

tion with an electrostatic effect so that

the outside air admitted to the passenger

compartment is purified and free of parti-

cles such as dust, pollen etc.

In addition to the above-mentioned

function there is also an effective reduc-

tion of the concentration of pollutants

owing to a layer of activated carbons on

the lower surface of the filter.

The filtering action takes place when air

is admitted from outside (recirculation

off) and when the air is recirculated (re-

circulation on).
