Abstract: A ventilation system for a mobile structure, in particular a motor vehicle, includes: a variably adjustable filter device including at least one controllable, variable filter characteristic with regard to a pollutant class; means for collecting information about the air quality in the surroundings of the mobile structure and in particular information about the air quality in an interior of the mobile structure; and a control unit for varying filter characteristics of the filter device in a variable, in particular continuous, manner, on the basis of the information about the air quality.

Abstract: A filter arrangement for a vehicle includes a flat filter element. The filter element has a filter medium and is integrated into an interior component of the vehicle. The filter element forms a surface facing an interior of the vehicle. In an embodiment, air flows through the filter element, and the air exits through the filter element into the interior of the vehicle.

Abstract: A filter arrangement for a mobile device includes at least one first filter element and at least one second filter element, which are arranged in an air duct of the mobile device. The at least one first filter element is a pleated filter and the at least one second filter element is an adsorption filter. The at least one first filter element and the at least one second filter element are separate and mounted in the air duct so as to be mutually spaced. The at least one first filter element includes at least one nonwoven layer. The at least one second filter element is a honeycomb filter including a plurality of channels which are delimited by channel walls.
