Air purification offers renewed hope in the fight against Covid-19, study finds

High-tech air quality control solutions could put an end to Covid-19 transmissions in hospitals, according to a recent trial.

As part of efforts to tackle Covid-19 outbreaks within healthcare settings, government officials are on the verge of approving a pilot study involving the use of air purifiers in hospital wards.

This is expected to be similar to the investigation recently conducted at a number of schools in Bradford, where air purification systems were used inside classrooms.

The announcement comes just weeks after separate research carried out earlier this year revealed that filtration systems were able to remove almost all airborne traces of Covid-19.

On that occasion, air filtration machines were switched on for a week in Covid-19 wards, then off for a week, and then for another week, before the air quality was analysed.

Encouragingly, Dr. Vilas Navapurkar – who led the study – revealed that almost all traces of airborne SARS-CoV-2 were removed.

Dr. Andrew Conway Morris, from the Department of Medicine at the University of Cambridge, explained: “We were really surprised by quite how effective air filters were at removing SARS-CoV-2 from the wards.

“Although it was only a small study, it highlights their potential to improve the safety of wards, particularly in areas not designed for managing highly infectious diseases such as Covid-19.”

Market-leading air purifiers are proven to inactivate airborne bacteria and drastically improve conditions inside most indoor environments – causing their popularity to surge since early 2020.
