Potable Aqua Germicidal Water Purification Tablets

Goid to have in case of an emergency

I love the fact that this purifier is in such a small container that you can carry it wherever you go. brilliant

If you have a habit of going hiking or off grid camping these will be useful. They are light and small. A bit of a chemical taste but no worse than tap water. Good value. Easy to use.

Very fast shipping and packaging is just like the picture but haven't opened or tried them yet so will have to wait and see. I did read adding vitamin c in the water can help neutralize the iodine taste but only after 34 minutes when the iodine is finished working/purifying. ******************************************************************** Some other comments about it on the internet.... The chemical name for vitamin C is ascorbic acid. When Iodine and ascorbic acid are combined in solution, a chemical reaction takes place. In this chemical reaction, the ascorbic acid molecule loses electrons, which are transferred to the iodine molecule. Chemists call this type of reaction an oxidation/reduction reaction (or redox reaction for short). The ascorbic acid is oxidized to dehydroascorbic acid, and the iodine is reduced to Iodide ions. Oxidation-reduction reactions always occur in pairs like this. The molecule that loses electrons is oxidized, and the molecule that accepts the electrons is reduced. ************************************************************************ Guess what else - it is an instantaneous chemical reaction. The ascorbic acid complexes the iodine on contact, removing both taste and color. Try it in a clear container. Watch the color disappear entirely before your eyes in a heartbeat when you invert the container to mix it. That color change tells you it's done. There is an important caveat: it only takes a VERY tiny amount (fits easily on the tip of a knife blade) of ground-up vitamin C tablet to do this in an entire gallon of water. Be advised that you will always add more than you really needed. No big deal UNLESS you forget to thoroughly rinse the water container before you add iodine the next time.
