Myth 6

Air filters do not necessarily have to be changed at each vehicle inspection. It is enough to clean them or blow them through with compressed air to restore their function.

Wrong! Consider the facts:

Permanent temperature loading of 80 degrees and temperature peaks of more than 100 degrees can occur at the filter element during vehicle use. Even materials of the highest quality will therefore age and suffer fatigue. Also, any attempt to clean an air filter can have very detrimental effects:

• mechanical stress during the cleaning process can lead to rupture of the pleats – which means the end of the filtration effect

• the high cleaning air pressure may destroy the structure of the filter paper, so that the dust holding capacity is reduced

• dirt particles can enter the engine through broken pleats and damaged structures

• the reduced holding capacity in turn reduces the service life.
