Easy to install and maintain, the Watts Premier Five-Stage Reverse Osmosis Water Filtration Device is the most complete water filtration system available on the market. Featuring a five-stage filtration process, the RO incorporates sediment, coconut-shell carbon, and reverse osmosis technologies to provide great-tasting, bottled-quality water straight from your tap. The Watts RO filters in five stages to ensure that your drinking water is as healthy and clean as possible.

Once the system is connected, water passes through a 5-micron sediment filter that traps particulate matter--such as sand, silt, sediment and rust, that can affect the taste and appearance of your water. Next, a 5-micron coconut shell carbon block filter reduces chlorine taste and odor, as well as other materials that can give water a bad taste. For the third stage, another 5-micron carbon block filter further reduces chlorine, as well as difficult-to-remove chloramines.

The system's fourth stage of filtration is especially important, as it involves the passage of water through the reverse osmosis (RO) membrane. This semi-permeable membrane effectively reduces arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasytic cysts, such as giardia and cryptosporidia. The fifth stage of filtration utilizes a high quality GAC filter, which works as a final polishing filter when the water leaves the storage tank on its way up to your faucet.

The end result is consistently great-tasting water at just pennies per gallon. The system comes with everything you need in order to install including our long reach dispensing faucet. NSF tested and certified, this reverse osmosis system lets users rest assured that their drinking water is clean and safe. This five-stage system comes with a 3-year limited warranty.
