I have used in the past the 6 cup and then the 30-cup dispenser.  I was totally amazed when I first tried the ZeroWater, but now I am hooked.

When I first measured the water from the tap, it was over 230 ppm.  I tried Brita in the past and was disappointed.  It only cut it in half.

I now solely use the ZeroWater filters.  They last approximately one month before I have to change them.

I drink a lot more water and I use them in making powdered diabetic juices.  I noticed an immediate difference and so will you.
