主动式的空气净化原理。市场上的主动类空气净化器和双重净化类空气净化器一般只选择一种主动式的净化技术。市场上主要有银离子净化技术、负离子技术、低温等离子技术、光触媒技术和净离子群技术。主动式的空气净化原理与被动式空气净化原理的根本区别就在于，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，之后再通过风机排出，而是有效、主动的向空气中释放净化灭菌因子，通过空气弥漫性的特点，到达室内的各个角落对空气进行无死角净化。在技术上比较成熟的主动净化技术主要是利用负氧离子作为净化因子处理空气和利用臭氧作为净化因子处理空气两种。这两种就是典型的基于主动净化原理而进行工作的空气净化器。
Active air purification principle. Active type air purifier on the market and double purification air purifier purification technology generally take an active. The market is mainly silver ion purification technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and Plasmacluster technology. The fundamental difference between the active air purification principle and the passive air purification principle is that the active air purifier is free from the limitation of the fan and filter, and is not passively waiting for the indoor air to be filtered and purified in the purifier, and then discharged through the fan, but it is effectively and actively released into the air. Through the air purification sterilization factor, diffuse, reach each corner of the room air purification hassle. In the technology more mature, the active purification technology mainly uses the negative oxygen ion as the purifying factor to treat the air and the use of ozone as the purification factor to treat the two kinds of air. The two is a typical active purification based on the principle and to carry out the work of air purifier.
