Although facilities managers might think they’re saving a few dollars on electricity and air filters, “There's just no reason anymore to economize on airflow and filtration,” Macomber says. “That just doesn't make any sense. It's a cheap way to help people be healthier.”
Airborne transmission of SARS-CoV-2: the world should face the reality
National Center for Biotechnology Information, April 10, 2020
Hand washing and maintaining social distance are the main measures recommended by the World Health Organization (WHO) to avoid contracting COVID-19. Unfortunately, these measures do not prevent infection by inhalation of small droplets exhaled by an infected person that can travel distance of meters or tens of meters in the air and carry their viral content… Shops, offices, schools, restaurants, cruise ships, and of course public transport, is where ventilation practices should be reviewed, and ventilation maximized.
