设置有双层过滤装置，实现对细小颗粒的处理：不锈钢过滤芯高效过滤5μm上的有毒颗粒；活性炭过滤网高效吸附净化PM2.5等有毒颗粒；

Provided with double layer filters, realize the processing of fine particles:Stainless steel filter: HEPA5μm or more toxic particles;Activated carbon filters: high efficiency adsorption haze particles .

机身设置有两个进风口和一个出风口，进风口处各设置有活动挡板，可通过开启或关闭挡板实现除沙尘模式及自然换气模式；

Provided with two air inlet and an outlet and inlet settings active bezel, you can open or close the tailgate to achieve besides the dust model and natural ventilation mode;

产品内腔中设置有活性炭纤维和负氧离子发生器，特别是活性炭纤维的使用能实现0.3μm ~10μm的尘粒过滤，除尘能力达到空气PM2.5标准，使其不但有强力除尘除灰霾的功能，同时也具有净化室内空气的效果；产品采用两个独立内腔，使得隔音性能良好，除尘除灰霾效果显著。

Activated carbon fibers set in the lumen and the negative oxygen ion generator , in particular the use  of activated carbon fiber to achieve 0.3 µ m ~ 10 µ m dust filter, dust removal capacity of PM2.5 standards, making it not only a strong haze removal function, but also has the effect of indoor air purification.Two separate cavities, making good noise performance, haze removal effect.
