Maybe so but you and Grizz are failing to consider that every region or even each towns water may be different. So declaring that something works does not mean it works for everybody. I tried 5 different brands of distilled water for the Silvergen and it did not even come on.
I didn't just "jump" to my conclusion. I did a lot of testing and research. Distillation of my water does not remove all the flouride. All the store bought water did not have all the flouride removed.
Instead of protesting that you are right try being a little more open minded. I live in the goiter belt. The reason why we all have goiters is because we have excess flouride in our water. So, lucky you ...you don't need a Berkey with alumina filters...I do.
