Principle of anion generatorAnion generator turns the low voltage into high voltage by booster circuit and generates corona, then releases a great amount of electrons with high speed. These electrons are catched by oxygen in the air and the negative ion is generated. Its working principle is like that of thundering and lightning in the nature. The egative ion is considered as vitamin for the air, thats why the air become fresh after raining. . Miraculous function of negative ion:1.Making negative ionThe negative ion can effectively activate the oxygen molecule in the air make it more activate and more easily to assimilated and can effectively prevent air-conditioner related disease.2.Improve lung functionWhen people inhale negative ion, their lung can absorb 20% more oxygen and blow off 15% more CO. Thus it has an effect on improving sleeping, improving metastasis, strengthening disease resistance and so on..3. Disinfection: Small amount of ozone will be produced when the anion generator is working. Combined with negative ion, it can adsorb all kinds of virus and germ and make the structural change or energy transfer which may result in death.4. Abating smoke and odors: Negative ion can clear the dust smoke and odors by neutralizing their positive electronic charge and making them fall. It is effectively remove decoration smell moldiness and bathroom smell.5. Protection against Electrostatic Discharge (ESD): It can reduce television and computers harm to peoples eyes and keep TV and computer from dust.6. Protecting hair: The negative ion can neutralize positive ions and static electron, prevent hair from absorbing dusts to its surface and make hair fall smoothly
