Ventilation in schools

What is the best way to ventilate a classroom, what do you need to know about CO2 monitors and are air-cleaning machines worth the investment? NAHT’s James Bowen puts these key questions and more to the scientists involved in a critical research project looking at the effectiveness of ventilation and air purifiers in classrooms.  Professor Mark Mon-Williams, chair in cognitive psychology at the University of Leeds and professor of psychology at the Bradford Institute of Health Research, and mechanical engineer Catherine Noakes, professor of environmental engineering for buildings at the University of Leeds, are currently involved in a trial involving 30 primary classrooms to help our understanding of how air-cleaning technologies can help reduce the build-up of covid particles, as well as how they could have advantages in the longer term too.
