Air conditioning and refrigeration technology is Daikin's most distinctive highlight, but in terms of R&D and production of air purifiers, Daikin's advantages are not very obvious. Japanese brands of air purifiers often lack consideration for China's main indoor air pollutants, especially in the case of Daikin. Daikin's product range is small, the CADR value is generally between 200-400, the flagship product MC120MMV2 is only 700, and the purification rate still has a lot of room for improvement, while the particulate matter CCM value is P4, but the specific value is not specified, according to the feedback of online users, the filter is replaced about every 3-6 months.
 
The ability to remove formaldehyde has always been the weakness of Japanese brands, and Daikin is no exception, less than 50 formaldehyde CADR, most models do not even have the function of removing aldehyde, let alone the CCM value of formaldehyde, but in terms of deodorization, Daikin's built-in UP-titanium catalytic filter can effectively remove the odor emitted by cigarettes and pets, which is welcomed by many families, but the activated carbon layer also has a strong odor-absorbing function, and the UP-titanium catalytic filter also needs to be replaced frequently, so this technology does not bring much advantage to Daikin.
 
It is worth reminding that the "streamer energy" claimed by Daikin is essentially a negative ion purification function. The test of the Shanghai Center for Disease Control and Prevention showed that the inactivation rate of the influenza A virus drops within 1 hour was 65.33%, but this is after all the data in the ideal environment in the laboratory, and from the test report, the material used in the experiment is in the form of "drops", not fluidized air, and "1 hour" refers to continuous contact time. For air purifiers, in order to achieve a better disinfection effect, they need to run uninterrupted for more than several hours, and "streamer energy" will accumulate ozone when running for a long time, so it is recommended that users do not stay indoors when turning on this function for a long time.
 
The price of Daikin air purifier is not high, mostly between 2000-3000 yuan, but the anti-haze and aldehyde removal ability is more obvious than other brands, if consumers live in areas with slight haze, and there is no need to remove formaldehyde, and want to further improve indoor air quality, Daikin's air purification products are also a good choice.
