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. AIIRs are designed according to the requirements of ASHRAE Standard 170: Ventilation of Health Care Facilities.
