I wasn't sure what category to put this under... But I would like some info on what kind of water is best to drink. I have a friend who goes to get reverse osmosis water and fills up glass jugs every week. I've been using a filter that attached to our fridge, but it was recently checked by our electo- dermal screener, and she said it wasn't good. Now I'm using bottled spring water but I'm not do happy about the plastic it comes in. Is a Brita filter any good?
