Dr. Sreenath Bolisetty, Senior Scientist at ETH Zurich University (Department of Health Sciences & Technology), commissioned and supervised analytical testing of the Swiss Water Cartridge (20" POE Water Filter Cartridge) from Mam Nature Swiss AG. The filter incorporates a media developed at ETH Zurich University based on an amyloid-carbon platform.
Testing was performed with validated methods (ICP-MS/ICP-OES, EPA 537M for PFAS, fluorometry, and gamma counting/scintigraphy for radionuclides) under standard QA/QC. The cartridge is designed for whole-house application with flow rates of >1,800 Liters/h.
