Case of (4) Pentek 150235 Big Blue 20 x 4.5″ Whole House Filter Housing 1.5″ IN/. These are from a canceled project. They are new in the factory boxes. You are getting a case of (4) individual units. It is sized to handle the water for an entire household, even in areas where you need to filter a high flow of water and/or a heavy amount of sediment. The 1.25-inch internal port allows a greater volume of liquid to pass through the cap with more speed, while the built-in pressure release button in the cap makes it easier to loosen the sump when it’s time to replace the filter. The Pentek 150235 accommodates a wide variety of filter cartridges.
