Description: Air ionization is gaining acceptance as a method of choice for the purification of air. The method has been applied successfully to remove non-pathogenic particulates, such as smoke, dust, and pollen, from air. However, little is known on its effectiveness for the purification of air laden with pathogenic microorganisms. This study aimed to investigate the effectiveness of air ionization in removing aerosols loaded with viral pathogens. Reovirus bioaerosols were first generated into an airtight chamber. Subsequently, an air ionization system located within the chamber was activated to generate negative ions. Using biosamplers, samples were taken from within the chamber at predetermined time intervals (5 minutes, 10 minutes, and 30 minutes). A laser particle analyzer was utilized to monitor the size distribution and concentration of the bioaerosols prior and after generation of negative ions. Plaque assays were conducted to determine the infectivity of the sampled air. Preliminary results indicated that the air ionization system significantly reduced the infectivity of reovirus.
