In most cases, product labels do a poor job of reliably indicating whether PFAS are present—especially in items marketed for kids and teens. PFAS (often called “forever chemicals”) can show up in stain-resistant, water-repellent, and grease-resistant coatings, yet labels frequently emphasize performance claims without clearly naming the chemical class behind them.
One challenge is that many labels don’t use the term “PFAS” at all. Instead, you may see broad phrases like “water-resistant,” “stain guard,” “easy-clean,” or “nonstick,” which can signal the type of treatment where PFAS have historically been used, but don’t confirm it. Even when a label says “PFOA-free” or “PFOS-free,” that only addresses two older PFAS and doesn’t guarantee the product is free of other PFAS compounds.
Labels can be more helpful when they state “PFAS-free” or “fluorine-free,” but wording varies and isn’t always backed by the same testing standard. Some brands also use third-party certifications or material disclosures that provide stronger reassurance than a front-of-package claim. When labels are vague, the most practical next step is to look for a detailed materials list, chemical policy, or certification information on the product page or manufacturer site.

Claims like “stain-resistant,” “water-repellent,” “grease-resistant,” “nonstick,” or “easy-clean” can be clues, because those performance features have sometimes been achieved using fluorinated chemistry. They’re signals to investigate further, not proof of PFAS.
