Reverse Osmosis (RO) drinking water systems include mechanical filtration to remove particles, carbon absorption and adsorption to remove chlorine, taste, odor and chemical contaminants, as well as membrane separation down to .0001 microns. RO membranes remove dissolved solids at the ionic level. No other purification system can provide better removal. Reverse Osmosis Systems provide the best quality drinking water for your family.

The USRO4-60-JG, 4 Stage Reverse Osmosis System includes the following: 60 Gallons Per Day (GPD) Thin Film Composite Membrane, NSF Certified Quick-Connect Fittings, NSF Certified Metal Bladder Tank, NSF Certified 10 Micron Carbon Block, Inline GAC Post filter, Standard Faucet, John Guest Tubing & Accessories.

Your complete system includes installation parts, fittings and everything listed here.
