ABSTRACT
An experimental study and model analysis were performed to assess the effectiveness of commercially available in-room air cleaners in minimizing the impact of a hazardous aerosol released in a building. Two air cleaners were evaluated: a HEPA-type air cleaner and an electrostatic precipitator.
The effectiveness of a stand-alone room air cleaner depends on three principal characteristics: single-pass filtration efficiency, air flow rate, and the airflow pattern that the cleaner induces in the room. Accordingly, the air cleaners were first experimentally evaluated for their single-pass filtration efficiencies, which were determined for aerosol ...
