PFAS, or more precisely perfluorinated and polyfluorinated alkyl substances, which are also known as "eternity chemicals", pose a serious health risk. Numerous scientific studies have shown that PFAS can damage organs such as the liver and kidneys as well as the immune system.

In an alarming study, BUND found that 9 out of 10 tap water samples in Germany were contaminated with PFAS and is campaigning for a general ban on PFAS. 1 Protect yourself with the filbec water filter.
