SilverJeep said:Get a Berkey system. It will filter out just about anything. If you're worried about bacteria, put a couple of drops of chlorine in a gallon or so, then run it through the Berkey. It will filter out the chlorine.
Boiling and distilling take large amounts of fuel, if you don't have it or don't have the time, the Berkey worky!
I have one, love it!!
I have also got one. We used it in Africa (lot of bugs ;)) and it worked fine. I did not put any extra chlorine in it.
