Abstract High voltage electrostatic field is the key parameter impacting the effect of purification and sterilization of air purifiers. In order to determine the impact of the structural parameters of electrostatic field on air purifiers, the 2-demension characteristics of air purifiers was analyzed and simulated through finite difference method (FDM) in Matlab. Research on the impact of wire size, plate-to-plate distance, and wire-to-plate distance on the voltage-current characteristics was carried out. Finally, the correctness and effectiveness of the FDM was demonstrated by the experimental data, which provided valuable references for research on the sterilization principle of air purifiers and improvement of its performance.
