First, the filter material. Good filter materials (such as HE PA high-density filter media) have a capacity of more than 99.9% to adsorb pollutants above 0.3 microns.
Second, purification efficiency. The room is larger, and an air purifier with a large unit purification air volume should be selected, 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.
Third, the service life of bedroom air purifier. As the purification filter bladder tends to be saturated, the adsorption capacity of the purifier will decline, so consumers should choose a purified filtration bladder with regenerative function to extend its life.
Fourth, the room layout. The air purifier's inlet and outlet has 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 a ring inlet and outlet design product.
Fifth, demand. According to the type of pollutants purified according to the choice of air purifier, HEPA has a strong purification function for soot, suspended particles, bacteria and viruses, and the catalytic activated carbon has a better purification effect on odors and harmful gases.
Sixth, after-sales service. After the failure of the purification filter bladder, it is necessary to replace the manufacturer, so the products of the enterprise with perfect after-sales service should be selected.
