BoNew-Oral Himalayan Salt Pyramid Shaped Color-Changing USB Lamp With Wood Base and Bulb Best Gift For Friends

Working principle Crystal salt lamp can emit natural negative ions,especially under heating condition,can effectively balance the content of positive and negative ions in the air is a natural air purifier German Institute of biophysics has revealed the principles of air purification for salt lampstal salt stone is the main component of sodium salt,salt lamp absorb water from the air,and then evaporate, and then absorb water,and then evaporation,alternating reciprocating,in the process of continuous negative ions lamp heating the water molecules in the air around the absorption to the surface,when the salt and water molecules after mixing,will dissolve in water evaporation, Na+ and Cl- return to a neutral state and evaporated water carrying negative ions produced by the ionization of water molecules,so the air through this place get purification reaction unique process of ion generation only has crystal salt,because the electrical neutrality of the salt atomic structure determines the salt water in the presence of water,the existence of this negative ion capacity salt lamp is a natural shape, and the item you receive may not be the same as those pictures or the outbox,but they must have a posture! Natural things must have their natural beauty charm of a salt light lies in its lack of artificial shapes and patterns on the lamp body, ice fall, spirals, and so onrs are aware of this characteristic before they order.
