LAVIE turns tap water into pure mineral water via a glass bottle, which is placed in a natural bamboo case for 20 minutes. Its patented technology removes chlorine, chloramine, pesticides, chemicals, odors and tastes, but leaves all minerals and trace elements untouched. This process works due to electromagnetic radiation contained in the invisible solar spectrum, the UV-A. For each treatment cycle, the bottle, as well as the liter of water it contains, are completely sterilized, meaning no bacteria or virus can survive. The quality is comparable to commercial natural mineral waters.
