This is the old news, but I just found out from my geography class.
I always thought that clean water had to come from big filtering machines, which many people in LEDCs cannot afford to implement. Even when the clean water is filtered, it has to be packed and transported to the place where people need.
Instead of taking so much money and time on man-made water, why cannot we just have this portable and innovative water bottles? I know water is used not only for drinking, but I think this bottle is one of the most innovative products which will act as a pioneer to improve quality of life.
