Product Details
✓Two-Stage Effective Filtration with Anti-Scale Filter: Our whole house water filter features a powerful 1st-stage CTO filter (FC15B) that eliminates cloudiness, bad tastes, and odors. It removes over 90% of chlorine and effectively targets herbicides and industrial solvents. The 2nd-stage anti-scale ployfilter (FWDS80K) protects your household appliances and plumbing from scale. Our patented scale inhibitor efficiently sequesters calcium and magnesium, preventing scale buildup and clearing partially clogged piping.
✓Superb Filtration Capacity: Experience up to a full year of clean water (up to 50,000 gallons) for a family of four with our 10x4.5 replaceable whole house water filters. The 1-inch inlet and outlet ports ensure fast water flow with minimal pressure loss. Our premium quality CTO filter and anti-scale filter not only provide clean and fresh water to every faucet in your house but also extend the life of your water-using appliances and protect plumbing from sediment and scale buildup. They also inhibit corrosion on iron, steel, galvanized, copper, and lead pipes by forming a protective coating on their surfaces.
✓Easy Installation and Filter Change: The system comes pre-assembled on a mounting bracket for a streamlined, DIY installation. We include a filter wrench to make routine filter changes quick and easy. Additionally, a pressure release valve allows for the safe release of built-up pressure during filter changes. Consult our comprehensive manual and YouTube videos to install this point-of-entry (POE) filtration system at the main water supply and enjoy clean and healthy water for your entire family.
✓Retain Valuable Minerals: Unlike an RO system, our filtration system does NOT reduce Total Dissolved Solids (TDS), ensuring your water retains essential minerals that are beneficial to your health. If you're interested in a filter that removes TDS, consider exploring our iSpring Reverse Osmosis (RO) systems.
✓Peace-of-Mind Customer Service: We stand by the quality of our products, and your satisfaction is our top priority. Backed by a 30-day money-back guarantee and a 1-year warranty, our filtration system also includes an extended manufacturer warranty upon registration at iSpring. Our lifetime customer support and technical assistance from Atlanta, GA, USA, provide you with peace of mind. If you encounter any issues with our products, please reach out to us immediately. We are always here to help
