What the Sans Water Purifier is tested to reduce
SGS, an ISO/IEC 17025 laboratory, measured the purifier’s reduction of 19 contaminants (Dec 2023 to Mar 2024). These are the worst in Aurora’s water that were in that programme.
- Arsenic>97.2%Maximum measured reduction
- Hexavalent chromium98.6%Maximum measured reduction
- Perfluorooctanoic acid>98.8%Maximum measured reduction
Figures are the laboratory’s own, measured under test conditions. Your tap water differs from the challenge water.
