It rec- ommends opening windows, inspecting and maintaining local exhaust ventilation, and repositioning outdoor air dampers and temporarily disabling any controls that would automatically limit the supply air. It also advises using fans to increase the ef- fectiveness of open windows when weather permits or repositioning supply and exhaust diffusers to create directional airflow. And though it may require more investment, the CDC recommends adding portable HEPA fan and filter systems and installing ultravi- olet germicidal irradiation (UVGI).
