‘How Air Filtration Machines are Tested to Ensure They are Effective’ is a podcast with Dr Simon Harkis, manager of SGS’s air filtration lab in Milton Keynes, UK. Shining a light on the little-known world of a science that has been of great importance to the world in the last couple of years, it is now available to listen to online.
While we are all more aware of airborne viruses and pollutants, a lack of technical knowledge about how filters perform can seriously affect their performance in situ. Dr Harkis, who is Chair of SGS’s Global Filtration Technical Committee Chair, explores how these our assessments verify technologies that can detect particles smaller than the width of a human hair. He also discusses their possible effectiveness in stopping the spread of viruses like COVID-19.
In conversation with David Lilley of the Air Purification Trade Association, Dr Harkis explains how our state-of-the-art testing facilities help manufacturers to produce filters that can allow air, gas or liquid to move while crucially limiting potentially dangerous contamination, and meeting the high technical standards demanded from bodies such as IEC and ASTM.
