Is this the future of classrooms?

Students in the classroom could soon have a supply of sterilized 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. Sterilized 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. Researchers say their invention could be used in any confined space, including classrooms, cinemas, offices and theatres.
