75% of Americans are chronically dehydrated. This is also true for half the world population.
In 37% of North Americans, the thirst trigger is so weak that it is often mistaken for hunger.
Water purification is the removal of contaminants from raw water to produce drinking water that is pure enough for human consumption.
