ABSTRACT:
A filter arrangement for cleaning the interiors of ventilated vehicles, containing a coarse dust preseparator, a submicron particulate filter, and a gas filter, is to be improved so that the necessary filter lifetime can be adapted to the gas filter lifetime and a changing of the filters is necessary only when both are used up at approximately the same time. For this, a coarse dust preseparator or cyclone filter of high separation efficiency is mounted on an outer housing, downstream from which is at least one submicron particulate filter accommodated in a common filter housing and a gas filter as a filter module.
