High Performance: 600 GPD & 2:1 Waste Ratio: Capable of producing 600 gallons per day, this system provides fast and robust water flow which can fill a cup of water in just 9 seconds. The remarkably low 2:1 waste ratio means that for every 2 gallons of pure water only 1 gallon of wastewater is produced. This is 8 times less waste water than traditional 1:4 undersink RO systems, saving you money on the water bill and protecting the environment's natural resources. Premium 7 Stage Filtration: Provides highly effective filtration with a 7 stage dual cartridge design. The 4 stage CF cartridge is a composite pre-filter that removes sand, silt, rust, chlorine, VOCs and improves taste. The 3 stage RO Membrane cartridge filters down to 0.0001 microns, which removes more than 1,000 impurities including TDS, PFAS, microplastics, fluoride, arsenic, nitrate, lead, and other heavy metals to provide clean great tasting drinking water. Smart Design & Easy Install: The sleek minimalist design measures only 5.5" W x 14.75" H x 17.3" D takes up less than half the space of a system with a traditional water tank. Designed for easy hassle-free installation it comes with color coded water lines, adaptable feed water supply which fits both 3/8" and 1/2" plumbing, and step-by-step DIY instructions so you can set the system up in 30 minutes or less. Quick Change & Smart Filter Monitoring: Filters can be changed in just 3 seconds with a simple twist and pull. An integrated shutoff valve stops the flow of water as soon as a filter is removed so you won't have to crawl under the sink to turn off the water supply. The system monitors usage and the LED smart faucet lights up to indicate when a filter change is required. The 1st cartridge lasts 1,000 gallons or 12 months, and the 2nd cartridge lasts 2,000 gallons or 24 months. Next Generation Features: The system includes an integrated internal water-way to eliminate seals and connections where leaks can occur. This system automatically flushes the RO membrane with filtered water after use, which not only greatly extends the life of the RO membrane, but also prevents TDS creep. Flushing the membrane after each use ensures you get fresh filtered water in every glass. This 600 gallon per day tankless RO system by USWF provides on demand reverse osmosis filtration in a compact space saving profile with an impressive 2:1 pure to drain ratio meaning it produces 8 times less waste water than a conventional RO. The system comes with an LED smart faucet and performs intelligent monitoring to notify when a filter change is required, and the quick change filters can easily be swapped out in 3 seconds with a simple twist and pull. This system is easy to install and maintain while being packed with features like automatic membrane flushing and a leak free integrated internal waterway. The RO-2F-600 is the next generation of reverse osmosis filtration system.
