What is the purpose of a negative-pressure room?

A negative-pressure room works by keeping the air inside at a lower pressure than the surrounding areas, so airflow moves into the room rather than out. This inward airflow helps contain contagious, airborne pathogens, preventing them from escaping to other parts of the facility when doors are opened. The room is connected to a dedicated ventilation system that exhausts air (often through HEPA filtration) and achieves a specified number of air changes per hour. Doors should stay closed to maintain the pressure difference. If air inside were kept at higher pressure or the room were completely sealed, contaminated air could escape into adjacent spaces or accumulate inside, increasing the risk of spread. Hence, creating lower pressure inside the room is the effective method for containing airborne contaminants.
