Protect Your Family and Household Appliance from Iron, Manganese, and More: Our 3rd stage filter (FM25B) is specially designed for iron & manganese removal, reducing iron (MAX 3.0 ppm down to 0.01 ppm) and manganese (MAX 1.0 ppm down to 0.01 ppm). Our filter lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. The system also removes sediment, chlorine, rust, pesticides, herbicides, industrial solvents, and various other contaminants. 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 minimum impact on water flow (up to 15 GPM) and requires minimum maintenance. Top-Notch Quality: The first stage high capacity polypropylene sediment filter is able to achieve filtration down to 5 microns. The second stage CTO Carbon Block filter is made of high quality coconut shell carbon for maximum filtration efficiency and filter life. Both are tested by an independent third-party to meet NSF/ANSI standards. Both filters have a capacity of 100,000 gallons of water, enough to supply a family of four with clean water for a full year (depending on your water quality). 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: This system is installed at the main water supply line in order to treat all the water in your home. 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. ISpring Multi-layer filtration allows for less clogs and minimal pressure loss. ISpring carbon block filter uses high quality coconut shell carbon and highly compact fabrication tech for maximum filtration efficiency and filter life. ISpring iron manganese filter efficiently reduces iron (max 3.0 -> 0.01 ppm) and manganese (max 1.0 -> 0.01 ppm) Filtration Capacity: 50k gal at 3.0ppm for iron. If you are on well water, we recommend getting your water tested before purchasing the product for the best results. If you have any questions or need any product recommendations, please feel free to reach out. Q: With this whole house system, do I still need to install a water softener if my water is very hard? A: Yes, a water softener is needed if your source water has a high level of hardness, usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of whole house water filter cartridges. The harder the water, the greater amount of scale buildup occurs, and the sooner the filters get clogged. This whole house water filter can remove up to 95% of sediment, chlorine, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants that a regular water softener can’t, although it does not soften your water. It is recommended that you install this WGB32B series whole house system after your water softener to achieve optimal performance if you have hard water. Note: Water Softeners and whole house systems usually do not lower the TDS level of the water. An additional Reverse Osmosis system may be necessary for your drinking water. Peak Flow Rate: 15 GPM. Minimum Working Pressure: 25 psi. Maximum Working Pressure: 80 psi. Operating Temperature: 40-100 ºF. PH Range: 6 – 11. 1 inch NPT inlet / outlet. 100,000-gallon capacity replaceable highly compact coconut shell activated carbon filter provides a full year of clean water for your entire family. The WGB32B series is equipped with pp layered sediment filter and coconut shell carbon block filter. The densely packed carbon block filtration media provides more effective contaminant removal and longer filter life. This whole house system removes up to 95% of sediment, chlorine, chloramines, chemicals, heavy metals and other contaminants that create color, foul tastes and odors. (Tested by SGS, 2018).
