Outstanding Performance
iSpring FM15B iron manganese filter efficiently reduces iron (3.0 -> 0.01 ppm) and manganese (1.0 -> 0.01 ppm) and lasts up to 3 times longer than greensand. Filtration Capacity: up to 30K gal. at 3.0 ppm iron level
Safe Water For the Ones You Love
•Save on your water bill - the filters won’t produce any wastewater.
•Official 2nd stage filter for iSpring whole house water filtration system WGB21BM. Fits standard 10” x 4.5” filter housings.
•Unlike an RO membrane, the iron and manganese filter doesn't reduce Total Dissolved Solids (TDS). If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems such as RCC7 series and tankless RO systems like RO500.
