We replaced our water filter on our whirlpool refrigerator/freezer as we always do when needed. However, after purchasing the last very expensive Whirlpool filter, our water was barely running into cups or glasses. We checked lines etc., and finally decided to look for a more economic filter that would work with this refrigerator to see if there was a problem with the Whirlpool filter itself. That indeed was the problem. The filter purchased from All Filters, works great and immediately once installed, our water was running great into cups/glasses.
