Katadyn Micropur Water Purifier Tablets
These chlorine dioxide tablets are great for packing light, and involve no effort aside from dropping them into your water container. Adding one tablet per quart of water will kill viruses, bacteria, and protozoan parasites such as Giardia and Cryptosporidium. A potential disadvantage is the wait time for the tablets to work. Four hours is ideal for maximal purification, but you may not have to wait that long depending on water quality and the organisms present in the water. Planning your purification sessions ahead of time, such as right before bed, will make the wait time a non-issue. The tablets are individually wrapped, easily packable, and have a very long shelf life. Most users have found there to be little, if any, aftertaste. These tablets are a great addition to an emergency kit, and can be used in conjunction with a filtration system if you are extra-concerned over the quality of water that will be available during your trip.
