Beijing Yadu's air purifier performance is good, and it has been rated as one of the recommended brands of air purification products by CCTV's "Consumer Proposition", and its good reputation has promoted the steady growth of Yadu's product sales. In addition, Yadu is also one of the revision units of the new national standard for air purifiers, and its R&D strength has been affirmed by the industry.
 
Yadu has many models of air purifiers, from thousands of yuan to 10,000 yuan have corresponding products, "double-faced man" is one of Yadu's main product series. The so-called "double-faced man" is to configure two sets of filter solutions on both sides of the fuselage to improve the comprehensive purification performance of the product. KJ500G-S5 is a typical mid-range product, particulate matter and formaldehyde CADR values are 500 and 300 respectively, particulate matter CCM grade is P4, haze removal performance is satisfactory, but Yadu's formaldehyde capacity is doubtful, many models of formaldehyde CCM grade is not marked, in accordance with the requirements of the national standard, formaldehyde F grade is not marked by default CCM value is less than 300mg, this value obviously can not satisfy consumers.
 
It is worth mentioning that Yadu claims that it has developed UFCO platinum decomposition technology, which can continuously decompose adsorbed formaldehyde, and from the analysis of chemical principles, this technology is feasible and has a good decomposition effect under specific conditions in the laboratory. However, when applied to air purifiers, how much role UFCO platinum catalytic technology can play makes consumers can't help but put a big question mark, and its technical achievements are not reflected in the CCM value of formaldehyde.
 
KJ1660G-P16DD is the most high-end model of Yadu, the CADR value of particulate matter is close to 1600, and the purification rate is at the top level in the industry, but its test report shows that the specific value of CCM is only slightly more than 30000mg, as a high-end product priced at more than 29999 yuan, this performance is far from IQAir, Lake and other brands, and the cost performance is too low.
 
In addition, Yadu's motor is produced in Suzhou, the packaging process is more advanced, and it is a high-end product in the domestic motor, but Yadu's overall noise control ability still needs to be improved, and the noise value under the maximum wind stall is 68dB (A), although it does not exceed the limit line of the national standard, but this value will obviously cause some trouble to noise-sensitive users.
