A:AnswerThe directions says that if will NOT filter salt water. This might be used as a survival product?; but, the directions say that it filters out MOST bacteria (I am guessing that you could possibly still get sick if even one bacteria lives and you drink the bacteria?) Maybe, this product might need you to sanitize water before you use it? Still I like this product.
