Purpose of Cabin air Filter

The purpose of the filter is to trap dust and other air contaminants from the ambient air and remove the particles the air gets in.

Such particles can be liquid or in a solid state, for example in the form of dust, brake, tire and clutch wear, or pollen.

If dust particles now enter the cabin air filter, they stick to the fibers of the fleece.

The smallest particles with a size of less than 5 micrometers are attracted by the electrostatic charge, just like a magnet.

High-quality particulate filters can filter out almost 100 percent of all pollen, soot and dust particles from the incoming air using this process.
