Product Details
✓An anti-scale water filter that protects your pipes and household appliance from scale, corrosion, and more: The patented scale Inhibitor effectively sequesters calcium and magnesium. It also inhibits corrosion, particularly iron, steel, galvanized, copper, and lead, by coating the surface of your pipes. It also helps to stabilize chlorine as the chlorine will not react with the metal pipe if the coating exists. This water filter has a capacity of 250,000 gallons of water filtration.
✓Whole house water filter with standard size - Our water filter set fits standard housings that require 20” x 4.5” whole house water filter cartridges, including brand name models. The 20” x 4.5” whole house water filter replacement cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance.
✓A water filter with top-notch quality - Our filter (FG25B-KS) is specially designed to remove chlorine, lead, mercury, hydrogen sulfide, heavy metals, odors, and other contaminants. The third stage carbon block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. Both water filters are tested by an independent third party to meet NSF/ANSI standards. The filter pack has a capacity of up to 250,000 gallons of water filtration, enough to supply a family of four with clean water for a full year.
✓Peace of mind customer service - register online to activate your 1-year manufacturer warranty and lifetime free tech support from U.S. local support team. We stand behind our products and if you encounter any problems with any of our products please reach out to us immediately. We are happy to help!
✓Please note - Unlike an RO system, this whole house water filtration 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 consider our iSpring Reverse Osmosis (RO) systems. The polyphosphate filter does not remove calcium and magnesium from water - it only prevents those molecules from forming scale.
