Can air conditioning purify smog weather?

Air purifier products attached to air conditioners may replace single-function household air purifiers in the future. Zhang, president of Aowei Consulting Institute, told the media that air conditioners with air purification function will replace air purifiers due to the improvement of technology maturity and consumer health awareness. Indeed, as consumers, we are very willing to see such a future, saving money and space. Why not?

A previous test by China Household Electrical Appliances Research Institute showed that among more than ten air-conditioning products with purification function from four brands, the removal rate of PM2.5 could reach 90% within 2 hours, and the performance was close to that of traditional air purifier products.

Even so, Lu Jianguo, director of the Clean Technology Research Institute of China Household Electrical Appliances Research Institute, said that air purification is only an additional auxiliary function of air conditioners, and the core functions of air conditioners are cooling and heating. Moreover, he also stressed that clean air conditioning is not mature enough in technology. Due to the limited energy of air-conditioning fans, it is difficult to achieve auxiliary functions such as air purification while ensuring the cooling and heating functions.

Guangsheng Song, director of the National Indoor Environment and Indoor Environmental Protection Product Quality Supervision Center, also said that in theory, air conditioners can remove PM2.5 to some extent if they make rational use of high-efficiency filtration, electrostatic adsorption and other technical means. However, it is hard to say how these technologies are actually used.

summary

Although the utilization rate of air conditioners at home is much lower than that in previous summers, with the arrival of smog weather, many people remember this tall function when buying air conditioners. From the above analysis, it can be seen that the air purification function in air conditioning is not entirely a gimmick, but it still plays a certain role in removing indoor pollutants and PM2.5 Even so, as experts say, after all, air conditioning is mainly based on its own refrigeration and heating products. Even if there is a purification function, everyone should pay attention to the cleanliness of the filter and other parts when using it, which is not once and for all.
