WATTS® Reverse Osmosis System, 4 Stage, 16 in Height, Import

WATTS® Pure Water 4-Stage Reverse Osmosis (RO) System is a tried and true reverse osmosis system! WATTS® Pure Water 4-Stage RO System begins with Stage 1, a 5-micron Sediment filter that traps particulate matter like dirt, rust, sand, silt and sediment that will affect the taste and appearance of your water. Stage 2 is a 5-micron Carbon Block filter that provides a reduction of chlorine, chloramine and other materials that cause bad taste and odors (these are called PRE-filters because they filter in front of the reverse osmosis membrane). Stage 3 is the heart of the reverse osmosis system, the RO Membrane. This semi-permeable membrane is 1/10,000 of a micron and will effectively reduce TDS (total dissolved solids), sodium and a wide range of contaminants such as arsenic, lead, perchlorate, chromium, copper and radium. It will also remove over 99.95% cysts such as giardia and cryptosporidium. Stage 4 is a high-quality GAC final filter (this is called a final filter because it filters after the membrane). The filtered RO water passes through the membrane and enters the storage tank. When you're ready for use, it will leave the storage tank and pass through this fourth stage on its way up to the faucet. The end result - crystal clear, high quality, and great tasting water.
