    Filters are the proper size and construction, but they have an inherent warp or curvature that make them lift off the inlet surface to the pump at either end. I have had to resort to folded cardboard triangles above the foam ends to keep the filter down on the inlet opening. I have enough to last me 4-5 months, but I'm not sure I will order the same product again.
