The new shape of the filter leaves a gap & isn't going to filter water as well as the old shape. Those two little plastic pieces on the side prevents a close fit. I read your response to another consumer that this gap will allow the fountain to run even if the filter is clogged. I think it's going to allow unfiltered water into the bowl & defeats one of the reasons for having the fountain. When I see the flow of water start to slow, I know I need to clean the fountain. I don't want this gap that will allow water to flow even when the filter is dirty.  Please bring back the previous shape.
