Where can professionals who manage school, office, and commercial buildings get information on ventilation and filtration to respond to COVID-19?

Professionals who operate school, office, and commercial buildings should consult the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guidance for information on ventilation and filtration to help reduce risks from the virus that causes COVID-19.
