The cabin air filter functions

The cabin air filter, sometimes called a “micro cabin air filter” or “in-cabin microfilter”, is part of the ventilation, heating, and air-conditioning system. His main function is to clean the air going into the passenger compartment. The filter cleans out extremely small particles such as dust, pollen, smog, and other pollutants. Overall, it makes the passenger cabin a much more pleasant environment for the driver and his passengers. Nearly all late model vehicles are equipped with a cabin air filter, which should not be confused with the engine air filter.

The importance of a cabin air filter

These days, drivers rarely roll down their windows—most vehicles have air conditioning, the windows insulate against noise, and the air in urban areas is often polluted. As a result, the cabin air needs to be filtered to remove pollen, mould, odours, smoke, dust, and other pollutants that can affect passengers’ health. In addition to making the air in the interior of your car unpleasant and unhealthy, a dirty cabin air filter, clogged with dirt, dust, smelly mold and allergens, can also impact the performance of your defroster, heating and AC.

How often do you need to verify your cabin air filter?

Change cabin air filter on schedule or if there is an odour. Each vehicle’s user manual will indicate the manufacturer’s recommendation for how often to replace the filter. It may need to be replaced more often if you frequently travel in dusty conditions. A certified NAPA AUTOPRO technician will be able to answer any questions you may have.

The cabin air filter is often located behind the glovebox. A certified NAPA AUTOPRO Service Centre South Surrey technician can change it quickly during a routine inspection.
