Himalayan Salt lamp is beautifully cut into a heart shape, glowing with a delicate amber light. Did you know that Heart-Shaped Himalayan Salt Lamp in your home or office naturally improves your indoor air quality by creating healthy negative ions? It does this by drawing water molecules from the air to the surface of the salt lamp, and as the lamp is warmed by the globe, a gentle chemical reaction takes place. Healthy negative ions are then released into the air, counteracting the positive ions from electrical equipment around the home and office. The air is purified which means airborne bacteria, mold, viruses and allergens as well as respiratory irritants and asthma triggers cannot survive in the negatively charged environment.
