A fluid filter and a method for making it. The filter comprises a one-piece container having one open surface, a pleated filter element fitting in the container, and a cover fitting over the container's open surface. A trough in the container receives and positions three side edges of the filter element, and a mating channel in the cover receives and positions the element's remaining side edge. Fluid tight seals secure the four edges of the filter element in the trough and channel and secure the cover to the container.
