Abstract: The invention relates to devices for the sequential testing of filters comprising couplers for connection to the filter to be tested, a first assembly having an aerosol generator and a first measuring device for determining the aerosol concentration of the air, and a second assembly having a device for sucking in air in connection with a second measuring device for determining the aerosol concentration of the air downstream of the filter. The devices are distinguished, in particular, by a short preparation time and a short postprocessing time during the measurement time of the filter to be tested. For this purpose, the raw gas-side coupler is connected to a non-return valve. Furthermore, the first assembly is connected to the raw gas-side coupler via a first shut-off valve, the second assembly is connected to the clean gas-side coupler via a second shut-off valve and the actuating devices of the shut-off valves are connected to a control device.
