I use a Berkey water filter now. I wish I had found this article earlier could have saved a couple of hundred bucks. I had an idea that you could also use 55 gallon drums with the same set up. Seems like a lot of fly by night dealers for the berkey out there. Here is a reputable place to shop for a Berkey Water Filter . You can find them on Ebay, but try getting ahold of someone if something goes wrong.
