Do Shower Filters Remove PFAS? The Definitive Science Guide for 2025
TL;DR Most standard shower filters — carbon-only or basic sediment filters — do not effectively remove PFAS (per- and polyfluoroalkyl substances). However, certain media combinations — specifically high-capacity activated carbon fiber (ACF) and some reverse osmosis systems — can reduce PFAS levels. Nordisk's shower filters use ACF and GAC media that provide meaningful PFAS reduction. Here's the full science. --- What Are PFAS? PFAS (per- and polyfluoroalkyl substances) are a family of over 4,700 synthetic chemicals used since the 1950s in water-repellent coatings, firefighting foam, non-stick cookware, and industrial processes....
