Features 

1,  Four-stage purification design: filtering step by step enables harmful smoke to be better purified. Even for objects at least 8 times smaller than PM2.5, the purification rate can reach up to 99.997%. 

1.1  Active carbon filter element with catalyst can absorb multiple substances that exist in the air to be purified and are with foreign odor, toxic and harmful. 
1.2  Modular design for protection layer by layer: Independent replacement of primary, medium and high-efficiency filter elements enables longer service life of filter element and lower use cost. 
1.3  Energy conservation and environmental protection: Built-in circular initiative filtering method can prevent indoor cold air/warm air from flowing outside without destroying temperature and humidity environment in the operation section.

2, This product has the 1.4m universal smoke suction arm, which can be positioned and oriented arbitrarily (its length may be regulated according to customer requirements, without the support of external force). (A patent application has been filed.)
2.1  Original square-shaped smoke hood, uniquely structured in accordance with aerodynamics principle, has larger smoke suction area and better efficiency. (A patent application has been filed.) 
2.2  Easy installation and convenient use without the necessity of laying pipes otherwise.

3,  Adopt DC brushless motor that has stable performance and long service life. Low noise, high efficiency, low energy consumption, zero maintenance and zero consumable. 
3.1  The wind wheel, designed in vortex backward type, adopts special alloy material that could effectively prevent itself from being corroded. Unique dynamic balance correction technology enables it to operate more stably and reliably, with higher wind suction volume. (A patent application has been filed.)
