How to Make Pure Water from an Impure Source Without a Water Filter

1. You can use grapefruit seed extract or GSE. GSE is very bitter but will purify your water. It is recommended that you use from 10 to 25 drops per gallon of water or 1 to 2 drops per glass of water. You can also use GSE when traveling, especially countries like Mexico, to avoid getting diarrhea. It comes in a small bottle that is easy to carry or pack and can be found in most health food stores.
2. The old fashioned way -- bring the water to a boil for ten minutes to purify it.
3. As a last resort, iodine from a medical kit will purify water. Read the label and make sure it is 2% U.S.P. strength iodine. It takes about 20-40 drops per gallon. Stir and let stand for 30 minutes. Only use this method in an emergency and for only a couple days as it can build up in your system.
