iSpring WGB21B 2-Stage Whole House Water Filtration System, with 10" x 4.5" Sediment CTO(Chlorine, Taste, and Odor) Filter, 1" Inlet/Outlet
Main highlights- [Two-Stage Effective Filtration] The whole house water filter has 1st-Stage premium 5-micron polypropylene sediment filter (FP15B) captures dirt, sand, silt, dust, rust, and scale particles, using high quality coconut shell carbon and highly compact fabrication tech, 2nd-stage CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes over 90% of chlorine, and is highly effective on VOCs like pesticides, herbicides, and industrial solvents.
- [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.
- [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.
- [Peace-of Mind Customer Service] Backed by a 30-day money-back guarantee, 1-year warranty, and extended manufacturer warranty upon warranty registration at iSpring. Lifetime CS and tech support. We stand behind our products. If you encounter any problems with any of our products, please reach out to us immediately. We are happy to help!
- [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.
