I will use these on my bike tour, to kill off bacteria that remains in river water that has been boiled and filtered before using these pills. thankfully these pills will ensure that the water will be safe to drink.
Having tested them (they do not leave much chlorine taste in the water at all, hardly noticable) I have no worries that they will do the job, and I recommend this product to anyone who wishes to purify water.
[I would strongly suggest, however, if planning to use these pills on rainwater or river water (to make it safe to drink) that you filter the water first (to get rid of larger organic material), then boil it (to kill protozoa and bacteria) and then these pills to kill of any remaining nasties. That way you are being extra extra safe.]
