PFAS (per- and polyfluoroalkyl substances) — known as 'forever chemicals' — have been detected in UK tap water across multiple regions. Standard filters don't remove them. Only reverse osmosis and activated carbon block filters do. Here's what works.
What Are PFAS and Why Should You Care?
PFAS are man-made chemicals used in non-stick cookware, waterproof clothing, and firefighting foam. They don't break down in the environment — or in your body. Linked to cancer, hormone disruption, and immune system problems.
