- [Superb Filtration Capacity] 10"x4. 5" replaceable whole house water filters can provide up to a full year of clean water(up to 50, 000 gallons) for a family of four. 1-inch inlet and outlet ports allow fast water flow with less pressure loss. Fine PP sediment filter and premium quality CTO filter not only bring clean and fresh water to every faucet in your house, but also help prolong the lives of your water-using appliances and protect plumbing from sediment and scale buildup.
- [Easy Installation and Filter Change] The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included to make routine filter changes easy and quick. A pressure release valve allows for the release of built-up pressure when changing filters. Refer to our manual and/or YouTube videos to Install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family.
- [Retain Valuable Minerals] 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.
