How to distinguish the quality of commercial air purifiers?

How to distinguish the quality of commercial air purifiers on the market with the new national standard? Consumers can refer to the following three indicators.
1. Core Indicators - Clean Air Volume CADR Value
The new commercial air purifier national standard stipulates that the model of the commercial air purifier uses the maximum clean air volume (CADR) of the target pollutant (particulate matter and gaseous pollutant) corresponding to the product purification as a basic parameter for characterizing the commercial air purifier product. The CADR value represents the volume of clean air produced by the commercial air purifier for one hour of operation. The higher the value, the faster the purification rate.
The "Mobile Air Purifier PS-501T2" series of smog and aldoxime flagship products can remove PM2.5CADR values up to 620m3/h and remove formaldehyde CADR values up to 400m3/h. Taking the mobile air purifier PS-501T2 as an example, the CADR value is 620m3/h, and the applicable area calculation formula is multiplied by 0.07~0.12 according to the CADR value. The applicable area of the product is 43.4m2~74.4m2, even if the space is large. The living room with easy dust accumulation, the mobile air purifier PS-501T2 can also be efficiently purified to create a green and fresh air environment.
2. Cumulative purification (CCM) and service life
CCM refers to the total weight of pollutants that are accumulated and purified when the CADR value of a commercial air purifier is attenuated to half after long-term use. The higher the value, the longer the filter life. For example, the commercial air purifier has a cumulative purification amount of 10,000 mg for particulate matter. When the indoor pollutant concentration is 250 μg/m?, the commercial air purifier can work 10000/53=188. Day, or about 6 months.
It should be noted that the daily average processing volume of particulate matter in the table is calculated by the commercial air purifier daily working time of 12 hours. If the commercial air purifier works more than 12 hours per day, the daily average processing volume should be appropriately increased or decreased. According to this method, the service life of the Yadu double-faced KJ620F-P6 is 350 days, which is close to one year.
3. Performance level and noise level
The energy efficiency rating is calculated based on the ratio of the CADR value to the rated power. The higher the rating, the more power is saved. The mobile air purifier PS-501T2 has a high efficiency level of particulate matter purification, so you don't have to worry about power consumption even if it is turned on for a long time.
Shenzhen Lideng Environmental Engineering Co., Ltd. has created plasma air purification technology based on knowledge of physics, chemistry, biology and environmental engineering, and successfully realized Einstein's ionization theory. By simulating the natural air environment, the indoor air quality is significantly improved, and various harmful pollutants are effectively and quickly removed and decomposed. This is our belief that "the forest-like air can be enjoyed at home." Our technology solves many traditional problems such as activated carbon, photoion generators, ozone generators, high voltage static electricity, and photocatalysts. Our plasma air purification technology can effectively reduce dust in the air, neutralize and decompose pollutants in the air, disinfect bacteria, effectively control volatile organic compounds, and clean the air effectively!
