About This
- Protect Your Family and Household Appliance from Chlorine and More - Say goodbye to smelly, bad tasting water! Our system removes up to 99% of chlorine from water as well as sediments, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants. It works well with city water that has a low level of sediments.
- DIY Installation and Maintenance - Refer to our manual and our helpful YouTube videos for easy DIY installation. With 1” NPT inlet/outlet and 20” x 4. 5” filter cartridges, the system has a minimum impact on water flow (up to 15 GPM) and requires minimum maintenance. This system is installed at the main water supply line in order to treat all the water in your home.
- Top-Notch Quality - The CTO Carbon Block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. It is tested by an independent third-party to meet NSF/ANSI standards. The system has a capacity of 15, 000 gallons of water, enough to supply a family of four with clean water for half a year. The cartridge is individually wrapped to ensure freshness. Please unwrap the cartridges before use.
- Peace of Mind Customer Service - Register online to activate your extended manufacturer and life-time 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 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.
