An airborne infectious isolation room, or AIIR, is a type of isolation room that isolates patients infected with organisms that can spread via small airborne droplets (less than 5 µm diameter). The purpose of an AIIR is to prevent the spread of infectious diseases from an infected patient to others.

The Antec Controls Touchscreen Room Pressure Monitor (PMT), seen here mounted outside each AIIR, provides visible and audible alarms if room pressure is lost.
