The five stage WaterSentinel® WS-RO5 Reverse Osmosis System is designed to provide clean, clear, crisp drinking water for you and the whole family. Its compact design allows for installation where space is limited, yet powerful enough to deliver up to 50 gallons per day* of crystal-clear Reverse Osmosis water without the need of a booster pump or electronic components.

The WS-RO5 includes five stages of water filtration; a high capacity 5 Micron sediment pre-filter that removes sand, silt, sediment rust and other suspended particles, a Granular Activated Carbon (GAC) pre-filter with tremendous capacity for Chlorine Taste and Odor reduction, a high quality 5 Micron Carbon Block pre-filter to further ensure any residual chlorine is removed to preserve and extend the life of the Reverse Osmosis Membrane, a high production 50 gallon per day Reverse Osmosis Membrane and a final GAC Carbon final polishing filter. Built-in automatic shut-off valve shuts down the RO production once the storage tank capacity has been reached.

The WaterSentinel® RO System includes a built-in maintenance free flow restrictor so it won’t be overlooked during installations or filter maintenance. The WS-RO5 WaterSentinel® RO system includes everything needed for standard installation; RO System Module, High-Quality Brushed Nickel Air-gap Faucet, three-gallon compact water storage tank with ball-valve, feed water and drain saddle adapters. Simple to install and maintain, compact design RO System will provide great tasting drinking and cooking water for the entire family
