Himalayan rock salt crystals formed at the foothills of the Himalayas millions of years ago. The salt lamps cast a warm magical glow, while cleansing the ambient air and providing the soothing effects of colour on the mind and body. The salt lamp act as Natural Ion Generator and clean the ambient air by alternating actions of the salt's ability to first absorb water, and then evaporate it. The salt then neutralizes any unhealthy positive ions (pollution) and emits the neutralized molecule back into the air. The ambient air surrounding the salt lamp is measurably cleaned by the transformation cycle of hydrogen and oxygen, as well as sodium and chloride ions. Ideal for daily use in the home, near computers and televisions, around pets, in offices and anywhere else you want to improve air quality and promote health and wellness.
