A guide to help facilities managers better distinguish air cleaning technologies for different circumstances has been published by the Chartered Institution of Building Services Engineers (CIBSE).
The guide recommends businesses to get advice from specialist engineers before fitting any filters as different environments will require different technology as well as leading to various costs.
The document lists the different air cleaning technologies available and details how each can be of use to different businesses. For instance, some different technologies include high-efficiency particulate air (HEPA), ultra-violet (UV) germicidal irradiation, thermal or photocatalytic oxidation ion generation, or plasma devices electrostatic precipitation and other ‘novel’ proprietary technologies.
As well as providing an introduction to SARS-CoV-2 transmission pathways and removal mechanisms and it also summarises the existing guidance and makes general recommendations around the selection of air cleaning devices, including their performance, risks, and general maintenance.
The second part of the guide goes into more detail – providing a background to air flow performance metrics, pollutant and viral decay, and tools for assessing the performance of air cleaners in context. This section is aimed at building services engineers, facilities managers, and other technical staff involved in the selection and specification of ventilation systems and air cleaning devices.
