被动式空气净化器：被动式空气净化器的主要原理是用风机将空气抽入机器，通过内置的滤网过滤空气，主要能够起到过滤粉尘、异味、有毒气体和杀灭部分细菌的作用。而滤网主要分为颗粒物滤网和有机物滤网。颗粒物滤网又分为粗效滤网和细颗粒物滤网。这类产品的风机以及滤网的质量决定了空气净化的效果，机器放置的位置以及室内的布局也会影响净化效果。
Passive air purifier: the main principle of the passive air purifier is to pump air into the machine with a fan and filter the air through a built-in filter screen, which can mainly filter dust, peculiar smell, toxic gas and kill some bacteria. The filter screen is mainly divided into particle filter screen and organic filter screen. The particle filter screen is divided into coarse effect filter screen and fine particle filter screen. The quality of fan and filter screen of this kind of product determines the effect of air purification. The location of the machine and the layout of the room will also affect the purification effect.
主动式空气净化器：主动式的空气净化器摆脱了风机与滤网的限制，不是被动的等待室内空气被抽入净化器内进行过滤净化，而是有效、主动的向空气中释放净化灭菌因子，通过空气会扩散的特点，到达室内的各个角落对空气进行无死角

净化。市场上净化灭菌因子的技术主要有银离子技术、负离子技术、低温等离子技术、光触媒技术和净离子群离子技术等，该类产品最大的缺陷就是臭氧释放量超标的问题。
Active air purifier: the active air purifier gets rid of the restrictions of fans and filter screens. Instead of passively waiting for the indoor air to be pumped into the purifier for filtration and purification, it effectively and actively releases the purification and sterilization factors into the air. Through the characteristics of air diffusion, it can reach every corner of the room to purify the air without dead angle. The main technologies for purifying sterilization factors in the market include silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology. The biggest defect of this kind of products is the problem of excessive ozone releas
