Proposed Non-infectious Air Delivery Rates (NADR) for Reducing Exposure to Airborne Respiratory Infectious Diseases

In November 2022, the Lancet COVID-19 Commission Task Force on Safe Work, Safe School, and Safe Travel released a report proposing new Non-infectious Air Delivery Rates (NADR) for Reducing Exposure to Airborne Respiratory Infectious Diseases, exceeding the current minimum standards, and aiming to help mitigate infection risk and promote health.

The results from their study confirm that enhanced ventilation, filtration, and air disinfection are effective in reducing exposure risks for SARS-CoV-2 and other respiratory infectious diseases, as well as providing other benefits, such as improved cognitive function, fewer allergic reactions and unscheduled asthma visits for children, better subclinical cardiopulmonary health etc.
