additional benefits and potentially reduce patient risk).


11. Is the system designed for healthcare? (Currently air cleaning systems do not act directly on the patient and are therefore not classed as medical devices. This can affect things such as earth leakage current levels and if the system has a key to prevent inadvertent change of the settings).


12. In light of the current pandemic and Brexit, where is the system made? Can continuity of supply and spares be assured?


Ultimately, airborne transmission of pathogens remains a concern in the hospital environment. The above checklist can assist hospitals in ensuring they procure supplementary air systems that are fit for purpose and effective in the healthcare setting – helping to keep patients and staff as safe as possible from the transmission of harmful airborne pathogens.
