Venya Himalayan Salt Lamp. The open basket design of the Venya Himalayan Salt Lamp allows for maximum exchange of purifying negative ions. Himalayan Salt Lamps emit energizing negative ions, purifying the air, improving mood, and providing a natural-feeling light source. Negative ions help neutralize positive ions emitted from devices such as phones and computers. Water molecules attracted by the salt can carry positive ions. Salt crystals warmed by the bulb evaporate the water molecules, helping to neutralize the positive water molecules trapped in them. Naturally reduce dust and allergens from the air. Illuminated salt crystals create a soothing, therapeutic glow. 1 year warranty.
