Salt lamps can be used with either electric bulbs or candles, depending on the model, both emitting a soft golden light that lends visual appeal to a room. Not only do they look good, they also function as natural air cleansers. Heat from the bulb makes the crystal salt emit negatively charged ions which enter the air and neutralise the positively charged ions created by pollution and electrical appliances. These neutralised ions become heavy and fall to the ground.
