The Watts Premier Pure H2O 3-Stage RO Water Filtration System offers a compact solution for crystal clear, great-tasting water. Perfect for homes with limited under-sink or counter space, this system comes complete with three pre-installed filters, a chrome faucet, and a three-gallon storage tank. The first stage of this system features a 5-Micron Carbon Block Filter (H2O-F12) for removing sediments and chlorine taste and odor. The second stage features a 50 GPD RO Semi-Permeable Membrane Filter (H2O-F16) for reducing TDS like lead, chromium, cadmium, fluoride, barium, copper, selenium, radium 226/228, and turbidity, and the third stage features a GAC Carbon Filter (H2O-F17) for final water polishing. Constructed from high-quality materials, these pre-installed filters are built for durability and performance. For optimal results, we recommend replacing the carbon block filter every 6 months, membrane filter every 2 to 5 years, and GAC carbon filter every 12 months. Maintenance of this system is quick and hassle-free, thanks to a space-saving design with pivot filter heads that offer easy access. Additionally, each filter is equipped with a push button release, allowing for easy, tool-free replacement; simply pop the old filter out and push the new one in for continued clean water without the hassle. Backed by over three decades of innovation, Watts Premier has built a reputation for trusted, high-performance water filtration. As part of Watts Water Technologies since 2001, we remain committed to delivering systems that exceed industry standards, bringing clean, high-quality water into homes across the country.
