Functions: This machine is used to purify air, dispel peculiar smell, poisonous and organic gas. It can kill the bacilli living in the air, so it\'\'s efficient to avoid diseases of breathing organs, especially for the old and the little kids. It\'\'s also helpful to get rid of the smell of inks in those places where solvent printers or inkjet printers are used. It can reduce the CFU in the air, improve the air quality in a house and reduce the cross-infection of virus and bacilli among different people. It can be used continuously for 24 hours until the lamps are black out. So it\'\'s really a good choice for you to keep it, because it\'\'s so easy to keep you healthy. Theories: The lamp uses 365 wavelength electricity power, and when the light from the lamp shines on the glass which has a coated nanometer grade material, the interaction of electrons starts. The electrons meet the oxygen and hydrogen in the air and produce OH groups, then the oxygenation and deoxidization between OH groups and the organism of the air follows happens. The OH groups can restrain and kill the bacilli and stop the spread and cross-infection of poisonous gas. Applications: It is used in houses, bedrooms, hospitals, residences of the elder people, kindergartens, reading rooms, offices, entertainment places, cellars, factories with organic gas, working rooms with solvent printers or inkjet printers and some other places where the air quality and ventilation are not good.
