Salt lamps cleans and deodoriser the Air. Probably the most well known benefit and why the majority of people use them - is due to their incredible power to remove dust, cigarette smoke, and other contaminates from the air.
Himalayan Salt lams purify the air through the power of hygroscopy, meaning they attract water molecules from the surrounding environment - then absorb those molecules - as well as any other foreign particulates they may be carrying into the salt crystals. As the lamp warms up, from the heat produced by the light bulb inside, that same water evaporates back into the air and the trapped particulates of dust, pollen, smoke etc. remain locked in the salt.
Each lamp supplied with lead on/off switch and lamp.
Every crystal is unique and will vary in shape, size, colour and texture, The image shown shows a good representation of the product
