Andrew Conway-Morris et al. published results of a study where they show that air filtration and UV disinfection can greatly reduce SARS-COV2 in hospital wards. They installed portable UV disinfection units on two COVID hospital wards in the UK. The air was tested for viruses, bacteria, and fungi before the filters were turned on, during the time the filters were on, and then again after the filters were turned off.

Results show that Airborne SARS-CoV2 was detected in the ward on all five days before activation of air/UV filtration but on none of the five days when the air/UV filter was operational. SARS-CoV2 was again detected on four out of five days when the filter was off.

The study was registered as a service evaluation with Cambridge University Hospitals NHS Foundation Trust (Service Evaluation Number PRN 9798).
