We have two brita water filters and a ceramic water filter as well. I am not so sure what minerals are in our water because we catch our own and have a separate tank for drinking and a well for house hold stuff.

I was also under the impression that fluoride wasn't so bad I think there are worse things that go into town water.

I think if you want to be so cautious then maybe get a tank and use that for drinking water ??
