Main highlights

Whole house water filter that protect your family and household appliance from iron, manganese and more: Our 3rd stage iron water filter (FM25B) is specially designed for iron and manganese removal, reducing iron (MAX 3.0 ppm) and manganese (MAX 1.0 ppm). The water filter lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. This whole house water filter system also removes sediment, chlorine, rust, herbicides, industrial solvents, and more.
Top-notch quality - the first stage high capacity polypropylene sediment filter achieves filtration down to 5 microns. The second stage carbon block filter is made of high quality coconut shell carbon for maximum filtration efficiency and filter life. Both water filters are tested by an independent third-party to meet NSF/ANSI standards. Both water filters have a capacity of 100,000 Gal. of water, enough to supply a family of four with clean water for a full year.
Please note - this whole house water filter is installed at the main water supply line in order to treat all the water in your home; unlike an RO system, this whole house water filtration 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. The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use.
