Description

This paper aims to establish the performance testing method for domestic air cleaners to remove single gaseous chemical substance. At first, 4 experiments were performed with gaseous formaldehyde(HCHO) on 5 air cleaners : (1) filtration test by concentration-decay, (2) re-circulating test by concentration-decay, (3) filtration test by constant-emission, and (4) re-circulating test by constant-emission. These results suggest that type-(3) as same as a penetration test for gas-removal filters is appropriate and removal efficiency(η) as same as arrestance of filters obtained from this test is the best index to evaluate the performance. Further experiments with gaseous toluene and xylene were conducted. This testing method and index can apply to all air cleaners in spite of its mechanism.
