Negative ions are odourless and invisible molecules that are found in abundance in mountains, waterfalls and beaches, etc. They carry negative charge, while most pollutants in the air such as pollen, smoke and dust are positive charged.
Because opposite charges attracts, the negative ions and the pollutants are attracted to and stuck to each other. This combination changes the chemical composition of the pollutants, which will be sequentially destroyed and resolved. The air becomes clean and refresh at last.
