Abstract

In a heating/air conditioning system for a motor vehicle, with an exchangeable and selectively bypassable absorption filter which is arranged in a channel shaped housing and through which fresh air and/or circulating air can flow, a high degree of absorption is achieved when unprocessed air passing through internal leakage points at the absorption filter holder and the shut off bypass line of the absorption filter is collected and conveyed, via at least one line, to a location which is separated from the passenger space and the pressure level of which is lower than the pressure level on the flow off side of the absorption filter. Untreated air, which in certain circumstances escapes through external leakage points of a housing partition, is guided outside the passenger space, at the same time being prevented from overflowing into the latter.
