Uses fine mesh resin, (smaller bead-size) for more efficient grains exchange capacity and better filtration. Removes up to 10 ppm of ferrous (clear water) iron and/or ferric (red water) iron. Backwash rates on Ironsoft are a fraction of the requirement of ordinary iron filters, which allows the use of the Ironsoft on relatively poor producing wells. Solid-state microprocessor based LCD control valve.
