I was reading some articles about buying an air humidifier when I stepped into an "anion mode" which, if present, makes the divide much more expensive.
It's supposed to release negative ions along with the water vapor that will bond to dust and other impurities in order to "trap" those.

I informed myself more and these anions are produced by "applying a voltage to electrons, giving them the energy to cause ionization".

Along with this, the article I'm talking about claims that:
"Anion removes harmful substance created by electromagnetic wave. Electromagnetic wave emitted from electric and electronic appliances such as TV set and computer has a high level of energy, which creates positive ions in the air. If the density of positive ions rises in the air, it promotes secretion of hormones such as serotonin and free histamine in human body. This may cause asthma, bronchitis, trouble in eyesight, pain in waist and shoulder, nervousness, tension, irregular menstrual period, languor, mental depression and dermatitis, and even give a birth to a deformed baby. Chungpung air cleaner neutralizes and removes positive ions using anions generated on the above-described principle, and helps reduce secretion of stress hormone to cure various diseases including VDT syndrome and building syndrome. It creates lots of anions to promote the vitality of human body."

Now, in this article, positive ions are regarded as absolutely harmful as opposed to negatives. I'm pretty interested in really understanding the physics behind this topic, apart from publicity stunts :)
