Air Purifier Purchase Tips

1. Filter material. The ability of good filter materials (such as HEPA high-density filter materials) to adsorb pollutants above 0.3 microns is as high as 99.9%.

2. Purification efficiency. If the room is large, an air purifier with a large unit air volume should be selected. For example, for a 15 square meter room, an air purifier with a unit air volume of 120 cubic meters per hour should be selected.

3. Service life. As the purification filter bladder tends to be saturated, the adsorption capacity of the purifier will decrease, so consumers should choose the purification filter bladder with a regeneration function to extend its life.

4. Room layout. The air inlet and outlet of the air purifier have a 360-degree circular design, and there are also unidirectional air inlet and outlet. If the product is not restricted by the layout of the room, you can choose a product with a circular inlet and outlet design.

5. Demand. Choose an air purifier according to the type of pollutants that need to be purified. HEPA has a strong purification function for soot, suspended particles, bacteria, and viruses, and catalytic activated carbon has a better purification effect for odors and harmful gases.

6. After-sales service. After the filter cartridge is invalid, it needs to be replaced by the manufacturer, so you should choose the product of the enterprise with perfect after-sales service.
