Three hundred million years ago, a vast primordial ocean covered the area that would become the Himalayan mountain range. The salt of that unpolluted ocean was preserved as large crystal formations, which now yield the purest salt on earth. Aloha Bay's Himalayan Salt lamps emit negative ions. These ions cleanse the air by removing dust, pollen, dander, and cigarette smoke. They also offset the harmful radiation produced by computer monitors, TVs, and other electrical devices.
