The Earth Luxe Himalayan White Crystal Salt Lamp on wood base offers a holistic approach to home 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 white 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 into the air, providing an allergen/toxin free environment as well as imparting a variety of wellness and calming benefits. Est. 2-3kg/4.5-6.5lbs Salt Formation. UL/CUL Approved. Rock Salt, Plastic Cord/Plug. Salt Lamp can be cleaned with a damp brush or cloth after power source is disconnected. Bulb included.
