Abstract
A filter arrangement of a heating or air-conditioning system in a motor vehicle consists of at least two filters which can be flowed through one after the other. Non-confusable filter exchange is achieved with the filters having different external dimensions and their reception locations having reception sizes assigned to the respective external dimensions so that each reception location is only able to receive a predetermined filter.
