Researchers find way to filter coronavirus particles out of the air

A study by researchers suggests that air filters can remove almost all airborne traces of COVID-19. The findings by the University of Cambridge and Addenbrooke's Hospital could not only improve the safety of 'surge wards' but also opens up the possibility of setting standards for cleaner air to reduce the risk of indoor transmission. With fears growing of another potential wave this winter, the discovery could allow hospitals to better manage their repurposed 'surge wards' which can often lack the ability to change the air with a high frequency.
