Hosts Christine Seer-Closette and Rosie Guerin discuss PFAS, or "forever chemicals," with Wirecutter sustainability editor Katie Okamoto. They explore the health risks of these persistent compounds found in cookware, cosmetics, and outdoor gear. The episode evaluates PFAS-free alternatives, noting that ceramic pans often underperform while new waterproof fabrics and makeup formulas are effective. Listeners are advised to replace items only when necessary rather than discarding existing products immediately.
