The Smartwater brand was certainly accurate when they decided on the name for their product. Their water isn't collected from an isolated spring halfway across the world, but that doesn't mean they haven't deduced a way to produce some of the most delicious bottled water in the industry. They start with fresh water and send it through a system that applies heat in high doses to the water, which forces evaporation. That evaporation is the primary purification process since impurities can not follow the water through the evaporation process. The vapor is then collected and cooled, which causes it to return to a liquid state. At this point, the water is incredibly pure and essentially neutral within the body, so Smartwater adds a proprietary blends of electrolytes to boost the healthy aspects of the water. Minerals that are added include potassium, calcium, and magnesium, amongst others, and these minerals give the water a smooth, crisp taste.
