The thought of drawing water from a well in the sub-Sahara because you really need it is a wonderful thing.
At the very worst, Iodine tablets will kill of anything in the water, but they do taint the water with taste, take, half an hour ot work and are bad for you if you use them for a prolonged period of time.
Good though if space is precious and the use is infrequent.
I will be using them on my trip next year.
