We are a dental practice in the Kahala area that made the switch from a large jug deliver system to Water Group 7's solution. So happy we did. No more storing huge ugly jugs in the office, where we have little precious space to begin with!! Water taste great, and the unit is so much nicer looking. Also love Water Group 7's UV system for filling the water bottles on our A-Dec chairs - Lab verified basement level CFU. If you are using a water jug system to fill your chairs, have u verified it's CFUs level?
