From what I have read filtered water does not get rid of fluoride which is added to the water where I live. I read somewhere that distilled leaches the minerals out, but is good for a short term cleanse. that is the problem there is so much contradictory info. I found the site to buy the sun sound tape that David Sereda talks about on the videos that Antatriangle posted in this link .
