Description: OOTDTY Working Principle: By using pulses and vibration of electric appliances, rise low to for DC excessive unfavourable pressure. Making use of for DC of carbon brush tip to provide excessive emitting vast quantities of electronic at a excessive speed. Electronics can't dwell in the air for an extended for time, therefore,after reacting with molecules within the air , adverse ions will form. Features: Air purification, dusts coagulation, smoke elimination. Odor elimination (most of), launch from fatigue, stop from air-conditioner Adjust sleeping level.
