Question to the Department of Health and Social Care:

To ask Her Majesty's Government whether they have considered the deployment of professional high-efficiency particulate air purifiers as part of their response to the COVID-19 pandemic; and if not, why not.

The infection prevention control principles within current National Health Service guidance are applicable to all healthcare settings. The key principle of ventilation is to dilute COVID-19 through air changes and both air extraction and fresh air supply can be used to achieve this.
