Evaluating Portable Air Cleaner Removal Efficiencies for Bioaerosols

摘要

The overall objective of this study was to conduct experiments to quantify the rates at which bioaerosols are removed and/or inactivated by three portable air cleaners (PACs), and by the PACs combined with the operation of an upper-room air ultraviolet germicidal air irradiation (UVGI) system. Filtration has been used to reduce indoor pollutant concentrations in many settings and it has been shown to be effective in controlling a number of airborne contaminants.
