Product Details
✓Effective Anti-Scale Protection: Our water filter acts as a powerful anti-scale solution, safeguarding your pipes and household appliances from scale buildup, corrosion, and more. The patented Scale Inhibitor efficiently captures calcium and magnesium while also preventing corrosion, particularly on iron, steel, galvanized, copper, and lead surfaces. Additionally, it stabilizes chlorine, preventing it from reacting with metal pipes. This filter boasts an impressive capacity of 250,000 gallons for thorough water filtration.
✓Fits Standard Housings: Designed to fit seamlessly into standard housings that accommodate 20” x 4.5” whole house water filter cartridges, including popular brand-name models. These replacement cartridges ensure minimal impact on water flow, providing a flow rate of up to 15 GPM while requiring minimal maintenance.
✓Premium Quality Filtration: Our water filter system includes a first-stage carbon block filter crafted from high-quality coconut shell carbon. This design maximizes filtration efficiency and extends filter life. Independently tested by a third party, it meets NSF/ANSI standards and boasts a capacity of 100,000 gallons of water. That's enough clean water to sustain a family of four for an entire year.
✓Customer-Centric Support: Register online to activate your 1-year manufacturer warranty and gain access to lifetime free tech support from our dedicated U.S. local support team. We are committed to standing behind our products. If you encounter any issues with any of our offerings, please don't hesitate to reach out to us promptly. Your satisfaction is our priority, and we are here to assist you.
✓Important Note: Unlike reverse osmosis (RO) systems, our whole house water filtration system preserves the healthy minerals in your water by not reducing Total Dissolved Solids (TDS). If you're specifically interested in a filter that removes TDS we recommend exploring our iSpring Reverse Osmosis (RO) systems. Additionally, please be aware that while the polyphosphate filter prevents scale formation, it does not remove calcium and magnesium from water; its primary function is to prevent the molecules from creating scale in your plumbing system.
