I don't know how the Aquamira works, but years ago I bought a two-part system at the local outdoor shop. It may be the same as Aquamira.
The first part were the usual iodine tablets. The second part killed the iodine taste. When I read the label I discovered the second tablets were ascorbic acid, which I remembered from High School science class is simply Vitamin C. I could have saved a bunch of money buying Vitamin C rather than a incredibly over-priced "Iodine Taste Killer Tablet". I don't know if Aquamira is the same, but it might be worth checking out for those who use it.
