This filter
The Raintree™ PFAS Reduction Filter combines proprietary activated carbon fiber (ACF) with upcycled natural oyster shell media to reduce both long-chain and short-chain PFAS compounds (often called “forever chemicals”) through multiple adsorption mechanisms. It also helps reduce chlorine, unpleasant taste and odor, and various organic contaminants. Independent testing by Korea Conformity Laboratories confirmed reduction of six PFAS compounds: PFOA, PFOS, PFHxS, PFHpA, HFPO-DA (commonly called GenX), and PFBS.
