How to Make Your Own Water Filters and Purifiers

Create your own water filters using iodine crystals, cloth and charcoal filters to rid suspect water of chemical and biological contaminants.

Using iodine crystals to make a solution to pour into a larger container of water is one way to treat potentially unsafe drinking water.
