Which kind of indicators you must know when choosing the air purifier?
Air purifier was familiar to us and used by us. Many families, office, entertainment place began to use the air purifier, people pay more and more attention to the indicators and shopping factors, then where should we start when we buy air purifier?
Firstly: Follow the new national standard , focus on CADR and noise these two indicators. CADR affects the efficiency of purification, the greater, the better. In addition, CADR value also determines the effective coverage area, the general calculation is CADR × (0.07-0.12) = effective coverage area.
Noise is a measure of the technical level of manufacturers and materials, an important indicator of quality, some of the current use of DC brushless ultra-quiet motor, additional silent cotton technology, can effectively reduce noise, it is recommended to give priority to the purchase of these two silent technology machine.

Secondly: Choosing the main passive combination of purified air purifier as much as possible. Although some large brands of air purifiers using HEPA and activated carbon mechanical filter, the purification effect is good, but if it can release ion to purify actively, it can not only can improve the purification effect, but also can improve the service life of the filter.
Thirdly: Considering the cost-effective products, especially the filter. Purifier is a consumable type of household electrical appliances, the late use of the filter will be covered with a lot of dust, bacteria and other substances, the need for regular replacement of the filter, the need for a long-term cost of expenditure, we must fully consider the filter replacement cycle and cost, selecting more cost-effective products.
