Can Salt Lamps Improve Air Quality?

You’ve probably seen a Himalayan salt lamp before. These lights come in a variety of shapes and sizes, with the most common form being a single lightbulb inside of a large oblong piece of salt rock. Salt lamps are rumored to release negative ions, which are supposed to have positive health effects and to cleanse the air around them. How much truth is there in claims like these?

Salt Lamps Do Produce Negative Ions

If you’re fortunate enough to live near a beach, you may be aware of how relaxing and rejuvenating the ocean air is. Part of this has to do with negative ions produced by the combination of saltwater, sunlight, and wind.

In a similar fashion, salt lamps produce some negative ions just by emitting light through rock salt. But to a large extent, the jury is still out on whether or not this has a significant impact on indoor air quality.

The Salt Lamp Effect: Indoor Air Quality Improvement

Scientific studies have yet to prove the concrete effects of salt lamps on air quality one way or the other. However, some allergy sufferers have reported that their symptoms improved after using salt lamps. This suggests that the negative ions could have the effect of neutralizing allergens in the air.

Part of the reason salt lamps are thought to improve air quality has to do with the surface of the lamps being hygroscopic, meaning they attract water molecules. Pulling water vapor out of the air decreases humidity, which can purify the air somewhat by reducing the number of potential allergens, mold, and fungi, which thrive in humid environments.

When it comes to filtering particles out of the air, however, salt lamps obviously can’t do this. In order to decrease the amount of dust or other particles in the air, some kind of filtering system is still required.

It’s highly recommended to change the air filter in your home’s heating or cooling system every three months. You can also use a smaller HEPA-style filter in any room.
