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.
