The air quality in the cabin of a motor vehicle is receiving more and more attention.

Fresh, clean air improves the well-being of the occupants and contributes to the safety of the driver. Highly effective filter systems can already remove more than 90% of all pollen and road dust particles from the air flowing into the cabin today.

The filters which remove these particles from the air may not inhibit the flow of fresh air. Depending upon the profile of the requirements, they should also be in a position to retain unpleasant odors and poisonous vapors.
