空气净化固态污染物去除型：主要有机械过滤、静电集尘、静电驻极、负离子和等离子体法过滤等。其中：机械过滤、静电集尘、静电驻极为被动净化（过滤），只对经过过滤器材的空气进行过滤；负离子和等离子体法过滤为主动净化（过滤），净化器主动释放净化因子进行空气净化。
Air purification solid pollutant removal type: mainly mechanical filtration, electrostatic dust collection, electrostatic electret, negative ion and plasma filtration. Among them: mechanical filtration, electrostatic dust collection and electrostatic electret are passive purification (filtration), only the air passing through the filter equipment is filtered; negative ion and plasma filtration are active purification (filtration), and the purifier actively releases purification factors for air purification.
