- Encourage a vertical laminar rather than turbulent airflow
- Ensure a slow, steady air speed
- Direct potentially contaminated air out of rooms and away from people
- Replace fixed-speed fan motors with variablespeed ones to enhance the control of airflow and allow for a minimum setting that produces lower speed airflow
- Introduce sophisticated airflow-control systems, such as those that are sensitive to pressure, to allow for smoother adjustment of airflows
- Install high-performance air-purification systems
