I am an 18 year old from Minneapolis and I plan on heading to New Olreans very shortly to help out down there. I am brining a van full of supplies and one of the items I would like to bring with is a water purifier and filtration system. I'm thinking the best set up I could have would be either a carbon or a sediment filter, or maybe a combination of both. I just want something that could convert the flood water into drinkable water for people. Can anyone tell me what to build or show me a website?
