Country: Australia
This safety notice addresses the current promotion of portable recirculating air filtration devices to improve the air quality within hospitals to reduce the transmission of COVID-19. The purpose of this Safety Information Notice is to ensure: 1.the choice to use these devices is informed by evidence; and 2. where these devices are used, the selection is guided by a technical performance specification. This will ensure that matters such as placement, performance, consumables, maintenance, and spare parts are considered. Recommendations related to the appropriate purchase and use of portable air filtration devices are provided.

Device:
portable air filtration device, HEPA-filter

Environment / Equipment
  1. The research supporting the routine use of portable air filtration devices in hospital settings is not yet conclusive and indications for use are typically based on the failure to detect virus in the environment rather than reduced human to human transmission of COVID-19. In addition, the WHO recommends the use of these devices where the mechanical ventilation system is deficient and not as an adjunct to a well ventilated environment.
  2. The Technical Performance Specification, attached to this Safety Information advice, should be used to assist LHD/ Networks to select recirculating air filtration devices. See: https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0006/694473/MEMO-IPU-Bedroom-Performance-Specification-and-Supporting-Design-Guide.pdf
  3. Operational matters will also need to be considered and implemented to eliminate risks associated with routine cleaning and filter changes. For example, filter changes will not be carried out in clinical areas as a ‘safe change’ procedure will be needed as is currently the approach used with routine filter changes.
  4. Consultation with an environmental engineer, work health and safety and infection prevention and control advisors are recommended before purchasing an air filtration device to ensure all issues detailed in this Safety Information advice and Technical Performance Specification have been considered.
