无风机式负离子空气净化器是一种无需借助风机外吹和滤网过滤，利用自身产生的空气负离子对空气进行净化、除尘、除味、灭菌的环境优化电器，其核心功能是生成空气负离子，利用空气负离子本身具有的自然扩散性扩散到空间中、凝聚沉降颗粒污染物，分解甲醛等有害气体，杀菌消毒并营造负氧离子疗养环境的特性来对室内空气进行优化。其与传统的空气净化器的不同之处是以负氧离子作为净化因子，主动出击捕捉空气中的有害物质，而传统的空气净化器采用被动吸附过滤式的净化原理，通过风机抽风，利用滤网被动吸附过滤来净化空气，需要根据滤网的饱和程度(净化效果衰减程度)更换滤网，否则容易导致二次污染，而无风机式负离子空气净化器则无需风机和滤网，真正做到零耗材，零噪音。
The non fan negative ion air purifier is a kind of environmental optimization electrical appliance which uses the negative ion produced by itself to purify, remove dust, taste and sterilize the air without the help of external blower and filter screen. Its core function is to generate negative ion in the air, use the natural diffusion of negative ion in the air to diffuse into the space, agglomerate the settled particle pollutants, and decompose a Formaldehyde and other harmful gases, sterilization and build negative oxygen ion recuperation environment to optimize the indoor air. The difference between the traditional air purifier and the air purifier is that the negative oxygen ion is used as the purification factor to actively capture the harmful substances in the air. However, the traditional air purifier adopts the purification principle of passive adsorption filtration, which uses the fan suction and the filter screen passive adsorption filtration to purify the air. The filter screen needs to be replaced according to the saturation degree of the filter screen (the attenuation degree of the purification effect). No It is easy to lead to secondary pollution, and no fan type negative ion air purifier does not need fan and filter screen, so as to achieve zero consumables and zero noise.
