A new type of air filter has the potential to work faster, cheaper and better than any other, killing virtually all airborne bacteria and viruses in a fraction of a second.
It’s a germaphobes dream, and a bullish weapon against the spread of infectious diseases, some of which, like measles, can remain suspended in the air for hours on end.
The new device is not only effective at killing viruses, it can actually prevent disease. And if the technology can be miniaturised, the authors say it may one day replace the century-old face mask, allowing us to breathe clean air on the fly.
