Abstracts
In this study, the test results obtained from the performance tests for CA (Korea Association of Cleaning Air)
certificated air cleaners which had been commercially available in Korea from 2003 to 2015 were analyzed. Among
the test parameters such as flow rate, particle collection efficiency, clean air delivery rate (CADR), ozone emission,
odor removal efficiency and noise level, noise level and CADR were correlated with flow rates. Collection and odor
removal efficiencies were 20% higher than the limit of the CA certification. The ozone emissions from the air cleaners
were negligible because all the air cleaners were equipped with only HEPA filters, not electrostatic precipitation
method which produces ozone.
