Abstract The concern to indoor air quality increased as people understand relation of air quality and health. According to a report, the market size will increase to $ 23.8 Billion by 2020. Many performance test methods including AHAM AC-1-2015 were developed, however, the performance test results are not directly translated to the environment of customers’ houses. Air cleaning performance can be different because of air leakage, outdoor air quality, operation modes of air purifiers, and so on. An air purifier was deployed in a 36.8 m2 living room of a house which is in Daejeon, Republic of Korea. Clean Air Delivery Rate (CADR) was calculated by varying experimental conditions with all doors were closed. KCl particles were used as test particles and were generated by using six-jet atomizer. The initial concentration of test particles in the living room was not critical to CADR values. Due to the air leakage of the house, outdoor PM2.5 concentration showed negative relationship with CADR value. 10~30 μg/m3 of PM2.5 values were suggested as experimental range from the annual average of PM2.5 concentration in major cities in Korea and from the CADR measurements in this work. This research can contribute to preparation of test method of air purifier in the real environment as well as understanding of air purifier operation in the real environment. This research was supported by National Strategic Project through the National Research Foundation of Korea (NRF) funded by Ministry of Science and ICT(NRF-2017M3D8A1091919).
