No "filter" is going to distill salt water, as the salt is disolved, not a particle.If an emergency water filter was needed to be made, does anyone know how to construct one out of natural materials? I have heard you can use hollowed out logs and black ashes with other techniques to make a tube water can be filtered through, what effectiveness could be achieved and does this kind of thing work on salt water?
