Premium Efficiency Filtration: The initial stage CTO carbon block water filter, made from top-grade coconut shell carbon, guarantees superior filtration efficiency and prolonged filter lifespan. It drastically decreases chlorine levels by up to 99%, enhancing the taste and smell of water. This water filter has been independently examined to satisfy NSF/ANSI guidelines and can hold up to 100,000 gallons—sufficient for a family of four for a whole year.
Important Note - TDS Preservation: Unlike RO membranes, our system preserves essential minerals (TDS) while effectively removing harmful chemicals. For TDS reduction, explore our iSpring Reverse Osmosis (RO) systems.
DIY-Friendly Installation and Maintenance: Simplify your life with easy installation using our comprehensive manual and instructional YouTube videos. Featuring 1” NPT inlet/outlet and 20” x 4.5” filter cartridges, the system minimally impacts water flow (up to 15 GPM) and requires minimal maintenance.
