Sumary of Air filtration device removes almost all traces of airborne SARS-CoV-2:

  • A team at the University of Cambridge and Cambridge University Hospitals (CUH) NHS Foundation Trust investigated whether portable air filtration/UV sterilisation devices could reduce airborne SARS- CoV-2 in general wards that had been repurposed as a COVID ward and a COVID Intensive Care Unit (ICU).
  • During an intensely busy time, we were able to pull together a team from across the hospital and University to test whether portable air filtration devices, which are relatively inexpensive, might remove airborne SARS-CoV-2 and make these wards safer.
  • HEPA filters are made up of thousands of fibres knitted together to form a material that filters out particles above a certain size.
  • Additionally, the air filters significantly reduced levels of bacterial, fungal and other viral bioaerosols on the both the surge ward and the ICU, highlighting an added benefit of the system.
  • We were really surprised by quite how effect air filters were at removing airborne SARS-CoV-2 on the wards.
