About This
- [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.
- [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.
- [Premium Quality Material and Multi-Layer Density Tech] Complying strictly with FDA standard (CFR-Part 177) and tested by independent third party against NSF/ANSI standard((NSF/ANSI 42) for material safety and water quality, iSpring premium 5-micron polypropylene sediment filter (FP15B) captures dirt, sand, silt, dust, rust, and scale particles and extends the life of CTO carbon block filter. The polypropylene construction provides superior chemical resistance and is not prone to bacterial attack.
- [Highly Activated Carbon Block CTO Filter] Using high quality coconut shell carbon and highly compact fabrication tech, iSpring CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes up to 99% of chlorine, and is highly effective on Organic Compounds like herbicides and industrial solvents and other contaminants like trihalomethanes.
- [Exceptional Filter Life] This filter pack can filter up to 50,000 gallons depending on the use and feed water quality. Replace the filters every 3-6 months to achieve optimal performance. Fine PP sediment filter and premium quality CTO filter not only bring clean and refreshing water to every faucet in your home, but also help prolong the lives of your water-using appliances and protect plumbing from sediment and scale buildup.
