    • The invention relates to a suspended matter filter having a filter cell, the filter frame of which is arranged in a filter housing via a surrounding seal forming a test channel to which a test device can be connected. The object underlying the invention is to create a suspended matter filter of the generic type mentioned at the outset, the filter cell of which ensures, with inexpensive manufacture, continuously reliable and comprehensive pressure testing of the test channel and, on the other hand, allows the replacement of the expensive and complicated test device by simpler and cost-saving test apparatuses. This object is achieved in combination with the abovementioned generic concept by the seal being formed from a sealing strip (18), which is attached to the filter frame (14) and is made of a material having entropy elasticity, which sealing strip lies against free ends (19, 20) of legs of a rigid channel profile (21) situated on the filter housing (11). Such a test device can be used in all gas filters having a high separation efficiency.
