Turn up the lights, leave them on and shine them all around: numerical simulations point the way to more efficient use of far-UVC lights for the inactivation of airborne coronavirus

Summary

Computer simulations suggest that spreading far-UVC light through a room, rather than concentrating it, inactivates airborne coronavirus more efficiently. A modelling study.

Key points

• Simulations of far-UVC lamp placement and room airflow.
• More even coverage worked better than a single strong source.
• A model, not a test in a real room.
