Fundamental Operating Principle
The air pressure inside the room is maintained at a lower (negative) level than the pressure in the corridor and adjacent rooms. This way, when the door is opened, infected air in the room does not leak out; instead, clean air from the corridor is drawn into the room. The contaminated air in the room is passed through special HEPA filters, UVC, and atmospheric plasma, purified of viruses and bacteria, and a portion is recirculated inside the room while another portion is safely discharged to the outside of the building.
