Understanding whether Air Filtration from Air Conditioners Reduces the Probability of Virus Transmission in the Environment

Abstract

As the COVID-19 global pandemic continues to remain severe, people tend to spend more time in an indoor dwelling and, much of the time in the summer, people choose to sit at air-conditioned homes, offices, or travel in air-conditioned vehicles. In order to reduce the occurrence of health-care-related diseases, cleaning and disinfecting of such environment is critical as polluted air posed threat to human wellbeing, reduces the life expectancy due to cardiovascular and respiratory diseases, including asthma and pulmonary disease. People are less aware of disease transmission through air circulation in the air-conditioned environment. In particular, in the current times, virus particles, in addition to the various technological advancements such as the use of HEPA filters, appear to pass through the air from a person to the other. The present work examines the indexed publications in this area. The authors in this report have attempted to collect reports and studies on the HVAC system and the virus in order to get its illustration. The air filtration devices i.e. High Efficiency Particulate Air (HEPA) filters were found to play an important role in damping the rate of transmission of viruses.
