Water in a survival situation is one of the most important priorities you have, but it must be pure water.

This awesome method requires almost no effort and can be used in just about any environment.

That was pretty simple wasn't it? The best thing about this method is that for a survival situation it is endorsed by the World Health Organization and is used in developing nations that have issues with clean water.

While it is preferable to use sterilization pills or to boil your water, at least if you do not have those, you do have options.
