The purpose of this paper is to quantitatively determine the removal performance on cedar pollen of domestic air cleaners which have widely been utilized in ordinary houses. Five domestic air cleaners were tested in an experimental chamber, using cedar pollen and the JIS Test Powder. The evaluation were made with an index of equivalent clean air rates (ECAR). The results showed that the removal rates of cedar pollen were 19.12〜180.2(m^3/h) for 0.3μm particles, and 18.7〜213.0 (m^3/h) for 0.5μm particles except for one type and with JIS Test Powder 20〜50(m^3/h) for all type of domestic air cleaners. The pollen has smaller particle portion than the JIS Test Powder No.11 and the performance of cleaners cannot be estimated simply from the morphological size distribution of the test aerosols. The analytical prediction of pollen concentration were made and compared with the results of experiment to show a fairly good fit for particles smaller than 1μm.
