Emergency Water Filter

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?

No "filter" is going to distill salt water, as the salt is disolved, not a particle.
Not true. However, they are very expensive. Reverse Osmosis is the method of filtration. Brands and Products - KATADYN Brands and Products
True, but I have never heard of anyone successfully making a home made RO out of things they found in nature
