Abstract
A bacteria filter includes a pair of generally conical housing sections having confronting marginal flanges adapted to be welded together to seal the sections into an integral filter housing. The flanges have a pair of tongue-in-groove connectors to facilitate alignment of the sections during assembly and to automatically stretch a filter element between the two sections during assembly to optimize the filtering capacity of the filter. Each section of the filter device has a co-axial tubular neck extension defining an inlet and outlet of the filter device.
