Improving Ventilation in Buildings During COVID-19

The risk of spreading the coronavirus through ventilation systems is not well-known at this time, according to the CDC. However, in its updated ventilation guidance, the agency provides several steps employers can take to improve air quality and reduce the risk of the virus spreading in the workplace.

CDC suggestions include using fans to increase effectiveness of open windows; decreasing occupancy in areas where outdoor ventilation cannot be increased; and running the HVAC system at maximum outside airflow for two hours before and after the building is occupied. 12/15/2020
