Extended data

Selection skills of air purifier;

First, filter the material. A good filter material (such as HEPA high-density filter material) can absorb pollutants above 0.3 micron up to 99.9%.

Second, purification efficiency. If the room is large, you should choose an air purifier with a large unit purification air volume. For example, for a room of 15 square meters, you should choose an air purifier with a unit purification air volume of 120 cubic meters/hour.

Third, the 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.

Fourth, the room pattern. The air inlet and outlet of the air purifier have a 360-degree circular design, and there are also unidirectional air inlets and outlets. If the product is not limited by the room layout, you can choose products with circular air inlet and air outlet design.

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

Sixth, after-sales service. After the filter bag becomes invalid, it needs to be replaced by the manufacturer, so we should choose the products of enterprises with perfect after-sales service.
