Abstract: With the increasing demand of consumers for healthy and comfortable indoor environments, air cleaner have received increasing attention and product functions have been upgraded. They have gradually developed from particulate matter removal to products with functions such as formaldehyde removal, microbial removal, allergen removal, and can achieve automatic mode purification. Through research, it has been found that the core technology of the automatic mode purification function is the internally assembled air quality monitoring sensors and purification components. Through selecting the accuracy of pollutant concentration indication and the technical indicators of "response time, purification uniformity, and maximum concentration", multiple mainstream brands of air cleaners in the industry were tested and analyzed for comparison. Through comparative analysis, it is shown that the testing results of most products are relatively ideal.
