Product review (1 stars): Filters Out Even the Water
Each of the 3 filters only lasted less than 25 hours in a Samsung triple door refrigerator.  At this time the water flow was so low through the filter that you could hear the water pump trying to get enough water for the ice maker.  I contacted the company that sold them to me and stated that all 3 filters were bad, they sent me 1 (one) replacement filter.  Even the replacement filter failed after 72 hours.
