The issue of clean water has become a big issue in the world of health and humanitarian interests.
there are so many people need a water filter to get decent and good water to consume.
As far as i concerned, Flouride content in Indonesia is contained only in mineral packaged drinks.
So, if we want to avoid consuming flouride, then we should have our own water filters at home, school, office or other crowded places.
