I went through 2 of these filters now. the result SLOW FLOW!!! i believe i found the cause to the problem. If you would happen to look at your bypass cap that comes with the fridge and the filter and see the 2 parts that are raised inside the cap. The cap is raised higher than on the filter which would allow it to push the flow valve in further causing more water to flow. I believe on the filters it's not pushing the valves in far enough to allow a good water flow. the plastic mold isn't correct when they created the filters. The filtering isn't the issue it's the actual plastic mold itself I believe is the issue. Quite a shame for something that's so pricey.
