A new paper has just been published by members of the team titled, “Ultraviolet radiation vs air filtration to mitigate virus laden aerosol in an occupied clinical room” in Journal of Hazardous Materials.
Mitigation measures against infectious aerosols are desperately needed. Highlights from the paper include:
- In poorly ventilated environments, GUV can deliver equivalent air changes to portable HEPA filters set at high filtration rates.
- Upper room GUV devices can be enhanced by increasing air mixing.
- 254 nm GUV was more effective at inactivating SARS-CoV-2 than ϕX174 virions.
- 222 nm GUV was more effective at inactivating both SARS-CoV-2 & H3N2 compared to ϕX174.
