I have had my Zerowater dispenser for about a year.  I have never purchased bottled water, as I can’t abide using throw away plastic bottles.  I used to get two gallons of reverse osmosis water from Whole Foods, but since I can’t get to WF anymore, I purchased my beloved Zerowater dispenser.  It is easy to fill, clean and replace filters.  I can quickly check readings and make sure that my tap water (about 150 ppm) reads below 4 ppm after running through the filters.

My water tastes wonderful, so much better than tap water, and it even tastes better than the reverse osmosis water I just to get at WF.  

I love this product, it sits on my countertop, next to my sink, and I can easily refill it and dispense through the spigot.  I highly recommend Zerowater!
