A filter arrangement in the intake airflow of a heating or air-conditioning system of a motor vehicle, comprising two filters (preferably activated carbon filters), arranged offset and at a distance on behind the other relative to the direction of air flow, through each of which a partial volume of the air to be filtered flows. An air-guiding device is arranged upstream of the filters which feeds air proportionately to the two filters to produce a uniform supply. A wall capable of preventing flow round the rear filter, is provided between the two filters.
