Air purifiers mainly release negative ions. Negative ions have strong adsorption capacity and can effectively absorb harmful substances such as particulate matter and smoke smell in the air, so as to achieve the effect of purifying the air. The advantages of negative ion purifiers: the quality of clean air is light and floats up, the quality of turbid air is heavy and sinks, the quality of negative ions is light, the fan blows up along the vertical air duct, and the negative ions flow up along the air duct, spread to the whole space, and then form The large circulation purifies the air in every corner. product information Name: UV Air Purifier Weight: 358g color: White Size: 115*115*172mm Material: ABS Rated voltage: DC5V Rated power: 5W Applicable area: ≈20-30㎡ Product function: UV sterilization, ion purification Power supply mode: USB interface plug-in use Purification Type: Activated Carbon Filtration #Home Appliances #Small Household Appliances #Air Treatment #Purifiers #air purifier #Deodorizer #Air purification #dust #Mite removal #formaldehyde removal #K&S store
