Himalayan Crystal Salt Lamps are believed to create negatively charged ions in the air. By using a Himalayan Crystal Salt Lamp or Star Candle Holder, you replace the negatively charged ions in the air which help us to avoid the alleged physical and mental harm that the ’electric smog’ creates.Himalayan salt lamps are believed to filter dust, mold, mildew and pet dander from indoor air. Just as a nasal saline spray uses salt to clear airways, they help to relieve allergy symptoms of all kinds, aid sleep and can have a calming effect.Each 2kg Salt Lamp comes complete with light fitting, bulb & plug. The salt lamp is supplied in the protective cardboard box which may become damp in transit due to hygroscopic properties of the lamp. The smaller lamps are USB and can be plugged in via USB plug.Please note these items are fairtrade and come direct, so they will arrive in a brown cardboard box and can be Triangle or Circle in shape, White, Pink or Grey in appearance - please take into consideration that they do come from overseas as we are supporting fairtrade small businesses. PLEASE NOTE we now have the larger option available - just choose from the options Thank you Salt, USB Cable
