Potable Aqua Water Purification Germicidal Tablets

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

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.

Came on time packaging good, exactly what I expected!

These tabs seem to have a shelf life longer than expected. Functions at treating water and very little taste change. Easy instructions. From using this over the many years, use a water filter to improve taste.

I'll let you know if I die when the emergency happens if this didn't work...
