The HydroLogic® Big Boy offers big-time water purification. Whether connecting to water mains to filter water in the house, or using the optional Garden Hose Connection Kit to make it a stand-alone unit to fill reservoirs, get clean water faster and at higher volumes than ever before. This model's included KDF85 Carbon Filter adds even more filtering power by greatly increasing the unit's ability to remove chlorine, chloramines, iron, hydrogen sulfide and heavy metals, making it a great choice for city-dwellers. The Big Boy eliminates 99 percent of chlorine and over 95 percent of the sediment from the water, cycling seven gallons per minute with a 25,000-gallon capacity. A 20-inch by 4.5 inch two-stage filter unit, wall-mountable metal bracket, in/out pressure gauges, filter wrench and one-year manufacturer’s warranty are included with purchase.
