Update. I like the Zerowater system,but the filters end up being expensive and they filter out everything. So I looked into the Berkey system. The set of two filters handle 6000 gallons of water before needing replacement for around $100. I found a site that showed how to use food grade 5 gallon buckets to make a 5 gallon system for around $120 instead of buying Berkey's 2.5 gallon system for $250. I am not one of those people who need shiny stainless steel to please me if a better material is found. More capacity that will be a stronger system for a lot less money. The Berkey gets rid of chlorine and fluoride (with a second filter) and bad contaminants but leaves essential minerals in the water. And a big plus is that the Berkey system is actually approved for processing pool water and even river water into drinkable water. The Zerowater is not. Just passing this along.
