The cost of removing PFAS from medical devices Executive Summary The socioeconomic benefit of the use of PFAS in medical devices in the EU was calculated using three different methodologies to be 14.2 trillion per year (minimum 1.21 trillion per year, maximum 61.2 trillion per year), 1.99 trillion per year and 15.5 trillion per year (minimum 469 billion per year, maximum 38.6 trillion per year) respectively.
