This document summarizes three projects aimed at improving air quality in UK schools: 1) CIVOS investigated classroom ventilation and CO2 levels during 2021 and found levels decreased throughout the year. 2) CIVOS Phase 2 and another project will examine if remote training and in-class observations can improve ventilation behaviors. 3) Class-ACT is analyzing impacts of HEPA and UVC filters in 330 classrooms on attendance. It also outlines SAMHE, a new project that will gift air quality monitors to 2,000 schools and engage students/teachers through a web app. The goal is to create a national school air quality dataset and support interventions through citizen science.
