Chlorine Dioxide Tablets are a safe and effective method of disinfecting water. They kill bacteria, viruses and cysts in water, including Giardia and Cryptosporidium. Each tablet treats up to 1 litre of water and has very little after taste. Once water has been purified it should be kept in a sealed container. This container should either be kept in the dark or should be designed so that it does not allow light in, e.g. a metal water bottle. If these steps are followed, the water should be safe to drink for 2-3 days.
