A new method is presented to apply magnetic field in the air purification by collecting pre-charged suspend particles. Based on the experiments and analysis of the relative data, some effective factors, such as the polarity and value of the discharging-voltage, the direction and value of the magnetic field, the initial particle speed, and the collecting plate span, etc. on the process of air purification are discussed. The results show that the purification efficiency is enhanced by proper magnetic field. -6 kV direct current voltage is an optimal value and there are two optimal values of the plate span and the initial particle speed according to different situations.
