Product review (1 stars): Filter causing serious heartburn
Replaced the old filter with one of these 6 weeks ago and have been having the worst heartburn since. Two days ago, I went back to just tap water and the heartburn is gone. I don't know if it's something I'm reacting to or if it's something bigger, but I don't know what to do. Do I buy a different brand? These cost me almost $80 and I still have two left!!!!
