Salt lamps are unique products in which a large block of salt is illuminated from the inside with a small source of warm light, which introduces a friendly and comfortable atmosphere to the room. In addition, salt lamps are natural ionizers that neutralize the influence of electromagnetic waves generated by various electrical devices such as computers or microwave ovens. After switching on the lamp of the appropriate size, matching the size of the room, the amount of negative ions increases to about 70% after just 1 hour.
