ABSTRACT:
A method of assembling a fluid filter begins with a step of aligning housing shells to form a housing. A seam is defined in an area where the housing shells contact one another. The housing shells surround and enclose a porous filter element, having an edge portion that is substantially parallel to an adjacent side wall of the housing. The next step involves heating the first and second housing shells in the area of the seam, such that the first and second end caps are fused together. Another step of the method involves moving molten plastic, from the seam area of the housing, inwardly to contact the filter element, such that the filter element becomes fixed in position in the housing. Preferably, the molten plastic is arranged to form a circumferential seal around the filter element. A filter made according to the method is also described.
