TYPOLOGY
Cabin Air filters can be designed as:
particle cabin air filter
active carbon cabin air filter
Usually only the cabin filter element needs to be replaced because housing is fixed into engine.
FUNCTION
Their objective is ensure in the passenger compartment the maximum protection against pollutants, dust, soot, bacteria, fungi, etc .
Active carbon cabin air filters provide moreover additional defence against unpleasant
odours, exhaust harmful fumes, benzene, ozone, etc.
WHEN SHOULD THE CABIN FILTER BE REPLACED
Following the vehicle manufacturer recommendation; Muller Filter advises to replace cabin air filter every 15,000 to 30,000 km or at least once per year; check the filter cleanliness every oil change.
The filter has to be replaced at short intervals, so that the pollutant particle accumulation will not cause any inconvenience to vehicle ventilation system.
DELAYED OR MISSED REPLACEMENT CAUSES
- insufficient performance of vehicle ventilation system
- offensive smells when starting up
- appearance of foggy which is difficult to remove
HOW DOES IT WORK?
The air aspirated from air-conditioner system pass trough Cabin filter before arriving into passenger compartment, ensuring protection against pollutants, dust, soot, bacteria, fungi, etc
Usually the filter element is inserted in a plastic housing sited under the car hood.
Normally, Filter element is produced with synthetic filter media surrounded from a rigid border , sometimes coated with a sponge gasket.
Moreover the Active-Carbon Cabin Filter has a layer of active carbon able to retains unpleasant smells, exhaust harmful fumes, benzene, etc.
FILTERING MEDIA
Particle cabin filter elements are manufactured with synthetic filtering media called NONWOVEN (not cellulose ). To guarantee an high filtering media efficiency, the non-woven material, during its manufacture, is subjected to a processing of electrostatic effect by means of high voltage, which guarantees the total retention of micro-particles harmful to the human organism.
Active carbon cabin air filters is produced with a particular media where the activated carbons are sandwiched between two outer layers.
Cabin Filter media guarantees a retention rate of 100% of particles greater than 3 micron and not less than 90% of 0.5 to 2 micron particles.
The filtration rating is about 0.5 to 3 micron.
