The COVID-19 pandemic has demonstrated the importance of indoor ventilation to control the spread of contagious diseases. For hospitals, controlling disease transmission requires a significant increase in the fresh air supply, according to to air filtration systems manufacturer Delbag.

In a research article titled Sensitivity Analysis of SARS-CoV-2 Aerosol Exposure, Christian Redder, a development engineer in the field of aerosol separation at Delbag, states that: “Very good ventilation of indoor spaces is mandatory. The definition of sufficient ventilation in regard to airborne SARS-CoV-2 (Covid-19) transmission follows other rules than the standards in ventilation design. This means that especially smaller rooms most likely require a significantly greater fresh air supply than usual.”

He goes on to state that “in terms of window ventilation, it has been found that many short opening periods are not only thermally beneficial, they also reduce the exposure dose,” and “long total opening periods and large window surfaces will strongly reduce the exposure.”
