The air purifier test chamber is the core equipment for evaluating the key performance of purifiers, such as clean air volume (CADR) and pollutant removal rate. The accuracy of its test results is directly related to product rating and market access. Among various influencing factors, the airtightness of the testing chamber is a fundamental condition for ensuring the reliability of experimental data. Once there is a leak, it will cause systematic deviation in the detection results.
