RO International (STG-1S) Full Skid 1,800-2000 GPD Reverse Osmosis System
Reverse Osmosis Systems for Home & Light-Commercial Use
A reverse osmosis (RO) system pushes water through a semipermeable membrane to strip out dissolved solids, lead, fluoride, sodium, nitrates and more — delivering bottled-quality drinking water straight from your tap. We carry 4- and 5-stage under-sink systems plus light-commercial units from Watts, Pentek, PureT and Isopure Water, rated from 50 GPD up to 380 GPD.
