商用空气净化器等离子静电除尘净化器装置电离区由密集的细金属丝按一定间隔排列而成，金属丝上通有4000伏静电高压，在其周围会产生电晕，空气通过时，空气中的微粒子将被剥去电子而带上正电荷(夜晚时或空气中含尘较多时可以看到工作状态的放电极针周围有蓝色的微弱弧光)。电离区在放电的同时产生多种自由基、活性较强的氧化剂，对通过空气中的细菌细胞的蛋白质、核酸起到破坏的作用，达到消毒抗菌的目的。

Commercial air purifier air purifier device, electrostatic dust plasma ionization region by fine wire densely spaced from the metal wire with 4000 volt electrostatic voltage, around which will produce corona, through the air, particles in the air will be stripped of electrons and positively (dust or air in the night more can see a faint blue arc discharge state around the needle). The ionization zone produces many kinds of free radicals and strong oxidants at the same time, and destroys the proteins and nucleic acids of bacterial cells in air, so as to achieve the purpose of disinfection and antisepsis.
