How important is the cabin air filter business for MANN+HUMMEL?

The above-mentioned trends make the cabin air filter a very im- portant product for MANN+HUMMEL with an excellent potential for growth.

It is used in vehicles with or without combustion engine and can also be used for the filtration of the air in private and commercial buildings.
