More than 300,000 patients a year pick up an airborne virus while receiving treatment in hospital. Now a new University of Southampton project is using space-age plasma technology to tackle infection control.

The University of Southampton’s Project PASTA (Plasma Air Sterilisation and Treatment Apparatus) adapts space technology for hospital infection control and carbon reduction. Using plasma similar to that in SpaceX’s Falcon 9, the system sterilises hospital air by killing pathogens and viruses.

Trials at Royal Hampshire County Hospital in Winchester suggest PASTA could improve air quality, reduce energy costs by 50%, and lower carbon emissions.
