I travel frequently in remote places... and the easiest to find substance for filtering water, although not perfect, is charcoal. It does a pretty good job of absorbing chemicals and if you add a little salt most bacteria die. It is not perfect, but if you are in the middle of nowhere it works pretty good.

while chlorine is by far the cheapest route, most industrialized countries use hydrogen peroxide (food grade) to purify drinking water..

Of course, you can use iodine, but I don't like the taste that it leaves in the water. I suppose we are more used to the chlorine/bleach taste.

You can bubble oxygen or ozone through the water. Ozone is more effective, but oxygen is more readily available and cheaper. All of the halogen answers are good. Please note that none of these produce distilled water. Chemical impurities are still present, including the disinfectant you use.

fyi bleach has chlorine in it. chlorine is the best way to go because O3 is really expensive, and other chemicals are harder to monitor

I have spoken to people who use bromine to purify the water in their swimming pools.

Silver has strong anti-bacterial properties. Silver goblets were thought to have magical properties as drinks drunk from them did not cause illness.
