The FXI-11 is a single-housing water treatment system with a drop-in 10” cartridge that reduces sediment down to 0.5 microns and reduces chlorine, taste & odor at a flow rate of 1.5 gpm for 15,000-gallons. The system includes IsoNet®, OptiPure’s patented scale inhibiting technology, which delivers consistent protection against the precipitation and accumulation of scale and provides a protective barrier to help guard against corrosion.
