Product Details

✓High Capacity Filters: The iSpring WGB21B-KS is a 2-stage whole house water filtration system featuring a 1st-stage CTO carbon block filter (FC15B) and a 2nd-stage KDF plus GAC carbon filter (FG15B-KS) . These filters work together to effectively remove up to 99% of contaminants, including chlorine, lead, mercury, and various heavy metals. Say goodbye to turbidity, cloudiness, bad taste, and foul odors (like hydrogen sulfide that smells like rotten eggs) for fresher, cleaner water throughout your home.
✓Great Water Flow: With its clever connection design and 1" inlet and outlet ports, the iSpring WGB21B-KS delivers impressive water flow rates of up to 15 GPM. For optimal filtration performance, we recommend changing the filters every 8-12 months based on the contaminant levels in your water source and usage.
✓Top-Notch Quality: The first stage CTO Carbon Block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. It is tested by an independent third party to meet NSF/ANSI standards. The KDF filter is super powerful to remove the unpleasant taste or odor left in chlorinated water while maintaining the protection benefits of chlorine. They also tackle problems like turbidity, cloudiness, colors, bad taste, and odors like hydrogen sulfide that smells like rotten eggs.
✓Effectively Removes Contaminants:A reliable shield that protects you and your family from ingesting harmful chemicals or contaminants in your tap water. Those filters have a filtration capacity of up to 50,000 gallons of water, enough to supply a family of four with clean water for up to a year.
✓Easy Installation and Filter Change: The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included to make routine filter changes easy and quick. A pressure release valve allows for the release of built-up pressure when changing filters. Refer to our manual and/or YouTube videos to Install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family.
✓Please Note: This system is installed at the main water supply line in order to treat all the water in your home. Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS) and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, please consider our iSpring Reverse Osmosis (RO) systems RCC7 series or tankless RO500.
