A beverage filter cartridge includes an outer container with a bottom, and front, back and side walls extending upwardly from the bottom to a peripheral rim surrounding an upper opening. The side wall is contoured to define interior ledges located above the bottom and extending between the front and back walls. A planar filter element having front, back and side edge regions is configured, dimensioned and positioned to subdivide the interior of the container into first and second chambers, with the front and back edge regions of the filter element secured respectively to the front and back walls of the container, and with side edge regions of the filter element secured to respective interior ledges of the container side walls. A beverage medium is stored in the first chamber. A cover is joined to the container rim to close the upper opening. The cover is yieldably piercable to accommodate an inflow of liquid into the first chamber for combination with the beverage medium to produce a beverage. The filter element is permeable to accommodate passage of the beverage from the first chamber into the second chamber, and the container bottom is yieldably piercable to accommodate an outflow of the beverage from the second chamber to the exterior of the cartridge.
