Product Description The Home Master Jr. F2 Sinktop Water Filtration System delivers exceptional water purity with its advanced multi-stage granular filter, which removes up to 93 percent of fluoride, arsenic, chlorine and other chemicals. The Home Master Jr. F2 is easy to install and features an attractive space-saving design. Its superior performance has made it one of the best sinktop water filtration systems on the market and it's all backed by Perfect Water Technologies. What separates the Home Master Jr F2 from the competition is its granular filter? Many granular filters suffer from a condition where the water bypasses the filtration media completely. A fully channeled and bypassed filter will look like the inside of an anthill, and a substantial amount of the water will pass through it unfiltered. The Home Master Jr. F2 solves this problem by using compression disks, filling the filter cartridge completely, then installing compression disks at the inlet, outlet, and between layers to ensure even filtration. Space-saving design. Home Master Jr. F2's efficient design makes it perfect for any rental home, apartment or temporary living space. Its compact design allows it to fit on almost any sink top. Plus, installation takes only a few minutes and in most cases can be completed without tools (see the installation video). This package contains a fully assembled Tap Master Jr. F2 with filter, sink faucet diverter valve, additional 15/16 x 13/16 faucet adapter, flexible connection tubing, long-reach chrome faucet, and instructions. Operating conditions: pH <7.5; feed water PSI 20 - 90 PSI; water temp 40 to 100 degrees F; 2000 ppm maximum total dissolved solids.
