The new Whirlpool WHKF-DWHBB20 20" Extra Capacity Household Filtration System is the latest system designed for even the largest homes and small complexes. It provides clean filtered water throughout the entire building – reducing wear on seals, protecting appliances, and keeping clothing looking new. Our whole home filtration systems reduce the dirt and rust present in municipal water supplies to improve water quality for bathing, cooking and cleaning. The WHKF-DWHBB20 is the perfect option for those looking for a more cost-effective system without the need for a large stainless tank.

The WHKF-DWHBB20 has a very high flow rate and is compatible with 1" pipes. It comes equipped with a pressure relief button for easy filter changes. This model is compatible with both the Whirlpool WHKF-CB4520BB carbon filter and the WHKF-GD4520BB sediment filters.
