Our crystal salt comes from the foothills of the Himalayas. These 200 million year old salt layers are high in minerals and trace elements, providing the highest quality of natural salt. When the rock salt crystal heats up, it emits negative ions. These ions clean the air by removing dust, pollen, dander, and cigarette smoke.
