When managing school classroom environments for infection prevention, AIRAH highly recommends that the report references the use of real-time infection risk models, such as that developed by Mahmoud et. al. in 2025. Models should be capable of assessing ventilation and f iltration system performance by using real-time particulate matter measurements for estimating infection risk and safe occupancy time. Such models support public health decision-making by defining maximum allowable class durations and break intervals, and support facility management in identifying zones where occupants can safely remain for longer periods, while highlighting areas that require intervention or restricted use. This enables optimisation of seating arrangements, allocation of high-risk activities such as speaking or group work, and evaluation of the impact of adding or relocating HEPA filters. From an engineering design perspective, these assessments
