Used during a stay in India to purify water in the absence of sealed bottles, I acknowledge that I have used this product for cleaning dentures or brush my teeth, taste and smell bleach being particularly strong (water is not drinkable effect ice, cold with particularity mitigate the smell). Having no syrup available, I could not otherwise see if it was possible to modify the taste and make it drinkable. Otherwise, I can say that a tablet makes it possible to purify 1l water in 30 minutes, which is fast and efficient when it is impossible to boil water.
