Is this the future of classrooms? Face masks that supply students with a steady supply of sterilised air could help prevent the spread of coronavirus in schools, scientist claims
- Professor at Alicante University has patented a unique and unusual design
- Involves a network of tubes plumbing in clean air and removing dirty air
- Individual face masks fitted to the system would be installed at fixed locations
- People would wear one of the masks and therefore all are breathing clean air
- Would allow for confined spaces to do away with social distancing and return to 100% capacity if all people don their mask
School pupils in the classroom could soon have a supply of sterilised air pumped straight to masks attached to their desks if an unusual new system is adopted.
Spanish experts have patented a design that involves installing a network of tubes to every seated position in a room.
Sterilised air, free of any coronavirus particles, will be injected into the system from a central pump and each person would receive their own supply through a mask.
The sprawling labyrinth of pipes would have two channels — one for clean air and one for exhaled dirty air.
Researchers say their invention could be used in any confined space, including classrooms, cinemas, offices and theatres.

As air goes into the network, it is exposed to specialised ultraviolet light, which zaps any potential contagions, killing them instantly.
Once the air has been breathed in an exhaled, it is separated out to ensure there is no mixing of breath from various people.
This reduces the likelihood of catching the virus from another person’s exhalation to virtually zero, the researchers claim.

Professor Antonio Marcilla at the Spanish university says this system guarantees the arrival of disinfected air to users simultaneously, while the exhaled air is also disinfected.
‘Both air streams are perfectly separated at all times so that mixing is prevented’, he adds.
As a result of everyone wearing a mask and inhaling air that is guaranteed to be uninfected, the need for social distancing is eradicated, the scientists say.
This would mean classrooms and cinemas could return to their usual layout and 100 per cent capacity, assuming the room has been decked out with the unusual contraptions and everyone faithfully dons their mask.
The project is still in its infancy but a functioning miniature model has been made in a lab and successfully scaled up to make a pilot plant.
Researchers do not give a price for how much implementing this dystopian network would cost, but say existing air con systems could be adapted at a relatively low cost.
There is no explanation for how people will safely enter or exit the room or other precautions, such as cleaning of the masks following use.
Schoolkids hiding in the back corner of the classroom are sat in the SAFEST part of the room to avoid COVID, study claims
The back corner of a classroom has long been the domain of mischievous children, but it may also be the safest spot in the room to avoid catching the coronavirus, a US study claims.
Schools have been hit hard by the pandemic, with many forced to close, cancel exams and overhaul their teaching methods.
New research backs this up, but also reveals that in a typical classroom the lowest concentration of coronavirus particles is often in the back corners.
Researchers from the University of New Mexico say this information could allow for high-risk students to be placed in the low exposure zones.
In the study, published in the journal Physics of Fluids, the scientists used a computer model to see how open windows, perspex screens on each desk and air conditioning impacts the spread of aerosols and droplets.
Khaled Talaat, co-author of the study, told MailOnline that the specific location of a room’s safe zones are dependent on its specific layout and ventilation.
But the researchers used industry-standard air conditioning systems and rooms of ‘realistic dimensions and size’, to make the findings as wide-reaching as possible.
