The newly designed tapered air duct takes up less space and uses plastic materials from South Korea's Samsung and Japan's Toray. The air duct is smooth and the wind flows more smoothly. The 9-leaf mixed-flow fan design combines the advantages of axial flow fans and turbine fans. While generating large air volume, it also generates large wind pressure, attracting dirty air from a distance into the purifier, and then blowing clean air out at an accelerated rate.

Air purifier purchasing tips:
1. Filter material. Good filter materials (such as HEPA high-density filter materials) have an ability to absorb more than 99.9% of pollutants above 0.3 microns. ?
2. Purification efficiency. If the room is large, you should choose an air purifier with a large unit purification air volume. For example, a room of 15 square meters should choose an air purifier with a unit purification air volume of 120 cubic meters per hour. ?
3. Service life. As the purification filter becomes saturated, the adsorption capacity of the purifier will decrease, so consumers should choose a purification filter with a regeneration function to extend its life. ?
4. Room layout. The air inlet and outlet of the air purifier has a 360-degree annular design, and there are also unidirectional air inlet and outlet. If the product is not restricted by the room layout, you can choose a product with an annular air inlet and outlet design.
