How Much Iodine Does It Take to Purify Water?

If you’re using tincture of iodine, use about 2 drops per quart of clear water and 10 drops for cloudy water. Let it stand for at least 30 minutes in order for the iodine to kill the nasties. Be warned that using tincture of iodine is going to change both the flavor and the color of your water.

If you’re using crystals, follow the directions on the bottle. One small bottle of iodine crystals can treat up to 2000 quarts. But if you’re in the US, this product is tough to come by because it was nixed by the DEA. Apparently it was being used illicitly to make crystal meth so they banned it even though it was a great, portable, inexpensive way to kill pathogens without drastically changing the flavor of the water.

If you’re using tablets, follow the directions on the packaging, though the most popular ones typically require 2 tablets per quart of water. Again, you’ll need to let the water sit for at least 30 minutes so that the iodine can effectively kill the pathogens in the water.
