The technology can kill an array of bacteria, fungi and viruses in seconds including providing a potential solution to prevent the spread of airborne infections.
The air filters, which are coated with a chemical biocide called chlorhexidine digluconate (CHDG), were rigorously tested and compared to commonly used standard ‘control’ filters in the laboratory, in industrial air condensing units, and in a trial onboard trains operating on the UK’s railways.
In the laboratory, Covid-19 cells were added to the surface of both the treated and control filters and measured at intervals over a period of more than an hour.
The results showed that, while much of the virus remained on the surface of the control filter for an hour, all the Covid cells were killed within 60 seconds on the treated filter.
Similar results were seen in experiments testing bacteria and fungi that commonly cause illness in humans – including E. coli, S. aureus, and C. albicans.
