Dust controling effect of the air filter cleaner was tested in chemical laboratories and a residence. The coarse dust impactor, the Roken dust counter and the electrostatic dust sampler were used for dust determinations. Air borne dust was decreased to one third∼one tenth of the control tests by the air filter cleaner, if the number air changes of caused by the apparatus was 5∼6/hr. This air filter cleaner was more effective on fine dust particles than on coarse dust particles, and most effective on the total dust concentration in weight.
