This is the state-of-the-art, 4-stage reverse osmosis (RO) water purification system for your drinking water. This technology produces the purest and finest-tasting drinking water available at any cost. It is housed under your sink with a chrome spout mounted on top of your sink top. It requires a cartridge unit mounted on the wall under your sink (12" long x 15" tall x 3" wide). Additionally, you will need space for the under sink tank, which is 9" wide x 13" tall. If you are not handy, it will require a plumber for installation (about an hour). Filters and the RO cartridge are easily replaced, with snap-in connections. Filters are replaced annually, and the RO cartridge lasts up to 3 years.
This is the system I use in my home. It is the finest water available at any price. (There is a 25% re-stocking fee for returned units)
