Do any of you folks know the shelf life of iodine water purification tablets?
I've heard that they are good for about two years if the bottle is unopened, and for about a year after the bottle is opened, but these times sound a bit short to me.
I would like to carry a few in a small, pocket sized kit and I don't want to carry a whole bottle. If they deteriorate quickly after being taken out of their packaging, I might rethink this idea. I also have concerns about buying ineffective tablets from a store that has had them sitting on their shelf for several years.
If brand makes a difference, I usually use Portable Aqua.
