These popular lamps are not only nice to look at but some have claimed they have air purifying benefits.
Approximately ten years ago the first salt lamps were sold as souvenirs in gift shops at the salt mines in Poland. These lamps are crystal salt rocks carved into various shapes and feature a hollow center where a candle or bulb can be inserted. When the bulb is switched on, or the candle is lit, a warm glow emits from the sides of the rock. Varying thicknesses of the rock and colors offer subtle light differences – some allow more light to shine through the rock and are therefore brighter, while others may glow more auburn.
Salt lamps are commonly used as night lights or an addition to living or dining room lights where softer, ambient lighting is preferred. You have probably seen them on display at health food stores, the chiropractor’s office or your local spa. A warm light can be relaxing in the bedroom or place of meditation.
Salt naturally attracts moisture from the air – look at your salt shaker in the humid, summer months and notice how much it clumps. The main purpose of a salt lamp is for aesthetic reasons, or good looks, but the lamp can also help with moisture levels in a small room. Since mold spores, bacteria and dander require moisture to stay airborne the salt lamp is considered an air purifier by default as it gradually absorbs moisture. When the lamp is lit with a candle or bulb it is warmed and the water absorbed will start to evaporate. Some manufacturers recommend leaving the lamp on continuously while others suggest this may cause a fire or electrical hazard.
There is disagreement between the retailers of salt lamps and scientists, see Sense About Science, as to whether the lamps emit negative ions into the air when lit. However, many products exist in today’s market offering “negative ion” purification systems.
You may prefer to first look at lamps in person before purchasing one. Call your local health food merchant or try a home décor store that is known for carrying unique products. Since you will be enjoying the lamp, look for a shape or size that appeals to you and a color that you like.
If you cannot find a local retailer there are many online stores that carry salt lamps. Look for one that offers a return or exchange policy in case of damage during shipment or if you receive the wrong item. As with all online purchases you will want to feel comfortable that the company is not a fly-by-night operation and will be around for awhile in case you have questions or wish to purchase from them again in the future.
Your lamp should come with a wooden base to collect any dripping or melting the salt may produce. This base will protect the night stand or other surface from water damage. Wood can be cared for with a natural oil intended for wood furnishings, follow the manufacturer’s directions but avoid getting the oil directly on the salt portion of your lamp. A damp cloth can be used to remove dust or particles from the salt lamp. Follow up with a dry cloth and run your lamp for a couple of hours after cleaning to prevent it from dripping.
