Abstract: A cabin air filter system for a vehicle, includes at least one particle filter element and a cyclone separator positioned upstream of the at least one particle filter element. The system includes a particle agglomeration device positioned upstream of the cyclone separator. A method for cleaning air to be supplied to a cabin of a vehicle, with the cabin air filter system.

Abstract: A cabin air filter system for a vehicle includes at least one particle filter element and an adsorption filter element that is spatially separated from the particle filter element and having at least one adsorbent honeycomb. The system further having at least one heating element adapted for heating the adsorption filter element for regeneration and a regeneration flap, wherein the regeneration flap is adapted to switch a regeneration outlet to the environment. The system is operable in a regeneration mode in that the heating element is activated so that the adsorption filter element is heatable to a temperature above a predefined regeneration temperature and the regeneration outlet is opened by the regeneration flap so that a regeneration air flow processed by the adsorption filter element is releasable to the environment. A method for cleaning air to be supplied to a cabin of a vehicle with the cabin air filter system.
