Salt lamps are blocks of pure Himalayan salt, so they come from the same region of the world. Also known as the ‘Vitamins of the Air’, they are made from the salt that came from ancient oceans, and serve as a perfect air ionizer. Nature produces negative ions to combat air pollution which is exactly what these salt lamps do - emit negative ions. Negative ions attract the harmful particles in the air, which are positively charged, and they balance and neutralize them, so that they lose their damaging characteristics.
The bulb inside of the lamp heats the crystal and supports the ionizing effect. Salt itself is hygroscopic and attracts the water from the surroundings. You can often see that the lamp is damp or even wet, especially in more humid environments. Due to the gentle heat of the lamp, the water quickly evaporates and during the evaporation process the beneficial negative ions get created. They go on to bind with excessive positive ions (bacteria, molds and allergens all carry a positive charge) and neutralize the electronic smog in your home. The lamp is a very pure source of light and its warm glow has a soothing effect.
Each salt lamp comes with a bulb and a base. It can be left on all night/day. When not in use for a long period of time, cover with pastic wrap and unplug the lamp
