Tips for purchasing air purifiers:

First, filter materials. A good filter material (such as HEPA high-density filter material) can absorb pollutants above 1.3 micron up to 99.9%.

second, the purification efficiency. If the room is large, you should choose an air purifier with a large unit purified air volume. For example, for a room of 15 square meters, you should choose an air purifier with a unit purified air volume of 121 cubic meters per hour.

iii. service life. As the purification filter tends to be saturated, the adsorption capacity of the purifier will decrease, so consumers should choose the purification filter with regeneration function to prolong its life.

iv. room layout. The air inlet and outlet of the air purifier have a 361-degree circular design, and there are also one-way air inlet and outlet. If the product is not limited by the room layout, you can choose products with circular air inlet and outlet design.

v. demand. Choose an air purifier according to the types of pollutants to be purified. HEPA has a strong purification function for smoke, suspended particles, bacteria and viruses, and catalytic activated carbon has a better purification effect for odor and harmful gases.

VI. After-sales service. After the purification filter bladder fails, it needs to be replaced by the manufacturer, so the products of enterprises with perfect after-sales service should be selected.
