I do not recommend using distilled water on a regular day to day basis. In over 25 years of practice, I have only seen negative things happen with the long term, (day to day)
use of distilled water. For short term detoxification and cleansing purposes, distilled water is very effective. For over twenty years I have been using and recommending solid carbon block water filters. These systems consistently earn the highest rankings with Consumer Reports magazine and other independent testing organizations. I would not drink unfiltered tap water. In a pinch, you could use the brita water filter, (available in most stores) but eventually you will want to invest in a solid carbon block system.
