I've used RO in my kitchen for years, but decided to go back to filtered tap water, because it contains valuable minerals that RO removes.
According to Larry Wilson MD, even filters like Pur and Brita do a good enough job of removing most contaminants.
He has a unique opinion on many things, and I've taken his advice many times over the years.
I was looking at gravity water filters on amazon, there are now many Berkey knock offs, for about $100 on amazon.
They do a good job of filtering water, as long as the filters are replaced at recommended intervals.
With better hydration you get better health, better elimination and better overall balance of minerals and electrolytes.
I think I'm going back to carbon water filters. They've come a long way over the years, and they do a great job if the filters are replaced at recommended intervals. Some people also recommend rotating 1 gallon plastic jugs of water such as Crystal Geyser or having it delivered to your residence or business in 3 or 5 gallon jugs. I want to get away from handling 5 gallon water jugs.
