Product Details
✓Protect your household appliances and plumbings from scale. The patented scale Inhibitor effectively sequester calcium and magnesium, preventing your pipes from scale and clearing partially clogged piping.
✓Prevent your pipes from corrosion and bio-growth. Our premium filter media inhibit corrosion, particularly iron, steel, galvanized, copper and lead, by coating the surface of your pipes. It serves as a protective layer that makes it harder for bio-film to form. The coating also helps to stabilize chlorine as the chlorine will not react with the metal pipe if the coating exists.
✓Top-Notch Quality: The filter is made of patented scale prohibitor and is capable of filtering up to 150, 000 gallons of water, or lasting for 12 months (depending on inline water quality). The filter is tested by an independent third-party to meet NSF 42/60 standards.
✓We offer both technical assistance and customer service support by phone or email out of our headquarters in Atlanta, GA. Our knowledgeable team is available to help you find a filtration solution that best solves your specific water concerns or to help with any after-sale support you may need. Our goal is, and always will be, to maximize your user experience.
✓Please Note: 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, consider our iSpring Reverse Osmosis (RO) systems.
