## Features

- Two-Stage Effective Filtration: Our featured 2nd stage filter (FM15B) is specially designed for iron and manganese removal, reducing iron (Max 3.0 ppm down to 0.01 ppm) and manganese (Max 1.0 ppm down to 0.01 ppm). Using high quality coconut shell carbon and highly compact fabrication tech, 1st-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 herbicides and industrial solvents. iSpring WGB21BM is THE system you need to protect your family and household appliance from iron, manganese, and more
- 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. Refer to our manual and our helpful 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. With 1 NPT inlet/outlet and 10 x 4.5 filter cartridges, the system has a minimum impact on water flow (up to 15 GPM) and requires minimum maintenance
- Top-Notch Quality: The first stage 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 iron and manganese reducing filter lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. Those filters have a filtration capacity of up to 50,000 gallons of water, enough to supply a family of four with clean water for up to a year
- Please Note: This system is installed at the main water supply line in order to treat all the water in your home. For well/pond water with very high iron/manganese please contact us for customized solutions. 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, please consider our iSpring Reverse Osmosis (RO) systems RCC7 series or tankless RO500

## Questions & Answers

**Q: Is it difficult to install by myself?**
A: The system comes with standard-sized connections, a detailed manual, and video tutorials. Many users can complete installation on their own, but a plumber’s assistance can make the process even easier and quicker.

**Q: Is there anything special I should know when installing this system?**
A: For best results, apply plumber’s tape and tighten the fittings evenly during installation. This ensures a secure setup and helps prevent seepage, allowing the system to perform reliably.

**Q: How long does the housing usually last?**
A: Made with high-strength materials, the housing is built for long-term use under normal water pressure. Adding a pressure regulator can further extend its service life.

**Q: Can I install this system outdoors?**
A: Install indoors in a well-ventilated area, shielded from wind and rain, and away from direct sunlight and heat. For outdoor installation, ensure insulation against frost and sun, and waterproofing for both the unit and the pipes.

**Q: Does this system remove TDS?**
A: The System is designed to reduce sediment, chlorine, and certain chemicals, effectively improving water quality and taste. It does not reduce TDS. If lowering TDS is your goal, we recommend pairing it with an iSpring RO system.
