Not to come out and disagree with this advice.....BUT
Distilled water is NOT for drinking. It is not pure water, and to put it bluntly.....it can kill you if it's all you are drinking.
Go to mercola.com and do a search on it. When I saw this, I was thinking how the bottled water plant I worked in years ago warned us about drinking the distilled water. Now I know why.
Filtered tap water should be fine, or get the RO water.
