Abstracts
We have developed an electrostatic precipitation (ESP) type air cleaner for indoor air quality and investigated its
performances regarding CADR (Clean air delivery rate), single-pass efficiency and gas removal efficiency. The ESP air
cleaner used an ACF (Activated carbon fiber) filter for gas removal and the ACF as a high voltage electrode for
particle removal. The ESP air cleaner was tested in a chamber with the volume of 1 m3 regarding CADR and gas
removal efficiency. The applied CADR area of the ESP was 1.8 m2. Gas removal efficiency was tested with 3 gases
(Acetaldehyde, Acetic acid, Ammonia). As the results of the gas removal efficiency, the ESP air cleaner shows the
removal efficiencies of 90, 98 and 85% for acetaldehyde, acetic acid and ammonia, respectively.
