I have no Water Purification tablets and wanted to know if there was a substitute.

  • Well, bleach and iodine are helpful in water purification. Where you looking for something specific? – Greg Hewgill Dec 30 '14 at 2:26

    Depending on where you're going, water purification may be totally unnecessary. For example, the scientific evidence shows that backcountry water in the Sierra is safe to drink without treatment. Different methods of purification also handle different types of bugs. So the place to start would be to tell us where you're going, then we could figure out if there are any nasties that need to be killed off. Then if there are, we could suggest a method that would work on that type of nasties. – Ben Crowell Dec 30 '14 at 2:34

    Boil the water, or buy a filter straw. – ShemSeger Dec 30 '14 at 6:07
