The Earth Luxe Himalayan Crystal Salt Lamp with USB Cord on wood base offers a holistic approach to home or office air purification. Natural salt formations are mined from the Himalayans. The formation is hand-chiseled to remove the core to allow for the addition of an electric lamp which radiates a soft pinkish-orange glow. The heat of the light in the salt lamp attracts water vapors in the air. These vapors hold allergens and toxins which attach themselves to the salt lamp leaving the atmosphere clean. The lamp then releases clean water vapors back in to the air, providing an allergen/toxin free environment as well as imparting a variety of wellness and calming benefits. Rock Salt, Wood, USB Cord/Plug. Salt Lamp can be cleaned with a damp brush or cloth after power source is disconnected. LED Bulb included.
