This guidance advises on the operation and placement of air purifiers and outlines possible risks of catching or passing airborne infectious diseases in particular types of school spaces.

This guidance recognises that most learning spaces rely largely on natural ventilation. During winter it is difficult to maintain a comfortable learning environment with natural ventilation.

This guidance has been developed in consultation with the Department of Health, Samsung and ventilation experts.

This guidance contains the following chapters:

  • Using ventilation to improve indoor air quality
  • Operation and placement of air purifiers
  • Maintenance and cleaning of air purifiers
  • Room risk ranking and management strategies

If you have any further questions about the operation and placement of air purifiers, please contact
