A natural rock salt binds the negative ions with excess positive ions. The lamp helps neutralize the electromagnetic pollution emitted by computers and office equipment. Using a salt lamp at home or at work can improve your concentration, enhance the aura of your environment and increase your productivity. The ambient air surrounding the lamp is cleaned by the transformation cycle of hydrogen and oxygen, as well as sodium and chloride ions. The resulting purified air is helpful in the relief of asthma symptoms and upper respiratory problems. Buy a salt lamp and live healthier and happier!
