From the Manufacturer:
Zennery Himalayan Salt Heart Shaped Lamps are not only visually stunning but provide innumerable health benefits. They are natural negative ion generators. Simply put, salt attracts moisture. The interaction of humid air with the surface of the salt crystal releases negative ions.
The negative ions binds to the position ions that are created by electronic devices known as “electronic smog” (computers, television screens, telephones, microwaves, etc.). The positively charged ions lose their damaging characteristics when attracted to the negative ions. Zennery Himalayan Salt Lamps are recommended to improve your environment’s air quality, atmosphere and help promote one’s physical and mental well-being. 6-8 pounds. This lamp plugs into any electrical outlet.
