Airborne-microbe filtration in indoor environments

Summary

States the filtration of microorganisms is a topic that requires special focus because of the unique characteristics of both filters and airborne pathogens in the submicron size range. Discusses aerobiological contaminants such as pollen viruses, animal dander, fungal and bacterial spores and bacteria. Addresses the critical aspects of filter sizing and provides a methodology for predicting a filter's performance against airborne microorganisms. Compares the results of some studies on the filtration of viruses and bacteria with theoretical filter performance. Also reviews some field performance results. Considers complementary disinfection technologies and the economics of filtration.
