Avoiding fogged windows, decreased heater performance and unpleasant odours are just some of the benefits of winter cabin filter replacement. That is the message from leading cabin filter supplier MAHLE Aftermarket, who say that replacing cabin filters should not be just focused in the springtime.

MAHLE Aftermarket experts say that pollen and pollutants that become deposited in the filter during summer months often only become really noticeable in winter. During an hour-long drive, up to 100,000 litres of air is passed through the passenger compartment, and in a commercial vehicle, this can rise to as much as 540,000 litres. All this air contains pollen, dust, soot, smoke, tyre and brake abrasion dust, apart from the significant health hazards created by ozone, gases, benzene and sulphur compounds drawn into the ventilation system. Regular cabin filter replacement ensures that these harmful pollutions are kept well away from the passenger compartment and is essential at all times of year.

MAHLE Aftermarket offers an extensive range of MAHLE Original pollen and carbon-activated cabin filters to provide the independent service sector with a guarantee of OE quality and specification.

The company says that if workshops struggle to convince customers of the wisdom of a cabin filter change they should  simply show the customer the contamination captured by an old cabin filter, after which, they will need little convincing.
