Applicable area: refers to the maximum living room area where the air purifier can meet the requirements for particulate matter purification. According to the provisions of the new national standard, the applicable area range = 0.07 ~ 0.12 * Cadr value. Users can choose the first range according to their actual conditions, and the corresponding maximum applicable space of the product can be obtained. The AHAM coefficient is approximately equal to 0.08. Compared with the new national standard, the applicable area specified by AHAM is a fixed value, and it also makes the area declared by enterprises relatively conservative, which is beneficial to consumers.

Cadr value: refers to the clean air volume. According to the definition of the new national standard, Cadr refers to the parameters of the purification capacity of the air purifier for the target pollutants under the rated state and the specified test conditions, indicating the rate at which the air purifier provides clean air. The higher the Cadr value, the higher the performance of the purifier.
When buying a car, we are willing to look at the displacement because they are all visual representations of the product performance. Like the former, the Cadr value is the most intuitive manifestation of the performance of the air purifier. The higher the value, the better the purification performance of the purifier. There are 1p, 1.5p, 2p and so on. We will select different pieces of air conditioners according to the needs of different family areas to ensure the effect. The same is true for air purifiers. The purification amount of air purifiers is different for different areas. Therefore, the applicable area can be said to be an intuitive reference value of air purification effect given by the government to consumers. However, since the new national standard has not been launched, most air purifiers have a virtual standard of applicable area. At present, this value can only be used for reference. (for consumers, the best way is to calculate the approximate applicable area through the formula: (0.07-0.12) * Cadr, and the coefficient of aham0.08 can also be used. The data thus obtained is more valuable for reference.)
