Air Quality COVID-19

Air Cleaning Technologies (ACT)

The Covid-19 Pandemic has wreaked havoc upon the education of a whole generation of school children. It is estimated that school children have lost at least a half of an academic year due to the pandemic. Education analysts report that all year groups have struggled, but it is most pronounced for Year 1 pupils aged five and six. There is a high risk that if no action is taken to mitigate airborne transmission, the risk of infection is likely to increase again in the autumn and winter seasons with the result being further school closures.

ACT is a multi-centred randomised control trial of two air disinfection technologies which have the potential to mitigate the airborne transmission of the Covid-19 virus within schools:

  1. Portable high efficiency particulate air (HEPA) filters
  2. Upper-room ultraviolet germicidal irradiation (ur-UVGI)

30 primary schools from across Bradford are trialling these technologies to assess both the feasibility and efficacy of using these in schools.

It is anticipated that the study will yield valuable information that will shape future UK Government policy regarding the deployment of air disinfection technologies in schools. It will inform on not just the effectiveness but also the practicalities of using these technologies in schools and is expected to influence whether or not there is a future nation-wide rollout of these solutions.
