"The iSpring WGB32B-KSNC 3-stage water filter system is a high-capacity, whole-house solution designed to deliver cleaner, safer, and fresher-tasting water for your entire home. Featuring a 3-stage filtration setup, it includes a 20” polypropylene sediment filter that captures dirt, rust, and debris, followed by a GAC + KDF filter that targets heavy metals such as lead and mercury, hydrogen sulfide, pesticides, and other common contaminants found in both city and well water. The final stage employs an advanced catalytic carbon filter, whose media has been tested by SGS according to NSF/ANSI 42 standards, proven to remove up to 94.4% of chloramine. This premium chloramine removal water filter system also efficiently reduces chlorine, VOCs, and unpleasant tastes and odors, providing cleaner, fresher-tasting water throughout your home. Enhanced catalytic reactivity enables the media to break down stubborn disinfectants more effectively than standard carbon, making it ideal for households using chloraminated municipal water. Built with durable housings and standard 1” NPT inlet/outlet connections, the WGB32B-KSNC ensures easy installation, strong water flow (up to 15 GPM), and minimal pressure drop. With a filtration capacity of up to 100,000 gallons per set, this system is a reliable, long-lasting choice for medium to large homes looking to improve overall water quality. Each cartridge is individually sealed to maintain freshness and peak performance. For complete water purification—including TDS reduction—pair this home water filter system with an iSpring Reverse Osmosis filter."
