Tips for choosing a purifier

1. Filter media. Good filter materials (such as HEPA high-density filter media) have a capacity of more than 99.9% to absorb contaminants above 0.3 microns.
Second, purification efficiency. For example, an air purifier with a unit purification air volume of 120 cubic meters per hour should be selected for a room of 15 square meters.
Third, the service life. As the purification filter bladder tends to be saturated, the adsorption capacity of the purifier will decrease, so consumers should choose the purified filter bladder with regenerative function to extend its life.
Fourth, the room layout. The air inlet and outlet of the air purifier have a 360-degree ring design, there are also one-way inlet and outlet air, if the product is not limited by the room layout in the placement, you can choose the annular inlet and outlet design of the product.
5. Demand. Choose an air purifier according to the type of pollutants purified according to the type, HEPA has a strong purification function on smoke, suspended particles, bacteria and viruses, and catalytic activated carbon has a better purification effect on odor and harmful gases.
6. 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.
