What does "pfas-free claim" really mean for your family?
A marketing label applied to cookware, air fryers, and other products to suggest they contain no PFAS (forever chemicals). The claim is entirely unregulated at the federal level -- no legal definition exists, no testing is required, and no government body verifies it before a brand prints it on a box. Understanding what PFAS-free actually means, how it differs from PFOA-free and PTFE-free, and which third-party certifications carry real weight is the difference between a genuinely safer kitchen and an expensive case of greenwashing.

Walk through the cookware aisle -- or scroll through any air fryer listing on Amazon -- and you will see "PFAS-Free" printed on boxes from dozens of brands. It sounds authoritative. It implies a standard has been met. It feels like a certification. It is none of those things.
At the federal level in the United States, there is no legal definition for "PFAS-Free." The FDA has not defined it. The EPA has not defined it. No federal agency requires testing before a brand can make the claim. A manufacturer can print "PFAS-Free" on a product without measuring a single compound, without disclosing what coatings or materials were used, and without any third-party review. That is the starting point every parent needs to understand before evaluating any PFAS-free claim in a kitchen product.
This does not mean all PFAS-free claims are false. Many brands that make the claim have genuinely transitioned away from fluoropolymer coatings. Some have commissioned third-party testing to confirm it. But the label alone -- without supporting evidence -- tells you almost nothing. And the marketing ecosystem around PFAS in cookware has been deliberately designed to be confusing, with claims like "PFOA-Free," "PTFE-Free," and "Non-Toxic" deployed in ways that exploit the gap between what consumers hear and what they actually mean.
These three terms appear interchangeably on product pages and in brand marketing. They are not interchangeable. Understanding the hierarchy is the foundational skill for evaluating any nonstick cookware or air fryer purchase.
PFOA-Free is the lowest bar of the three -- and it has been the lowest bar since 2015. PFOA (perfluorooctanoic acid) is a specific PFAS compound that was used as a processing aid in manufacturing PTFE (Teflon) coatings. Its toxicity profile, including its classification as a Group 1 carcinogen by the WHO's IARC in December 2023, led to a voluntary US manufacturer phase-out completed by 2015. This means that nearly every piece of nonstick cookware sold in the United States since 2015 qualifies as "PFOA-Free" whether or not the brand says so. The claim has become a marketing artifact: technically accurate and substantively almost meaningless. The product may still contain PTFE, GenX (PFOA's replacement processing chemical, with its own emerging toxicity concerns), and any number of other PFAS compounds. See our full entry on PFOA for the complete risk picture.
PTFE-Free is a meaningfully higher bar. PTFE (polytetrafluoroethylene) is the fluoropolymer that makes up Teflon and most generic nonstick coatings. Under the EPA and OECD structural definitions, PTFE qualifies as a PFAS. A product that is genuinely PTFE-free -- using ceramic, stainless steel, or cast iron instead -- has removed the primary source of fluoropolymer exposure from nonstick cooking. However, "PTFE-free" alone does not guarantee freedom from all PFAS: manufacturing aids, solvents, or other processing chemicals used to apply a non-PTFE coating could theoretically contain PFAS if not independently verified.
PFAS-Free is the broadest and theoretically most protective claim. It asserts that the product contains no intentionally added member of the 10,000+ compound PFAS family -- not just PFOA, not just PTFE, but the entire class. This is the claim that matters. The problem, as established above, is that it has no federal legal definition and no required verification method. A brand can make it because it sounds good, not because it has been confirmed.
The practical takeaway: a product labeled only "PFOA-Free" should trigger skepticism. A product labeled "PTFE-Free" deserves more attention but still warrants scrutiny about how the alternative coating was processed. A product labeled "PFAS-Free" with third-party testing or certification is the highest-confidence option available to consumers today.
The PFAS-Free claim has already produced major consumer protection litigation. In February 2025, HexClad agreed to a $2.5 million settlement resolving a class action that alleged the brand falsely marketed cookware as "Non-Toxic, PFAS-Free" while the products contained PTFE -- a compound that qualifies as a PFAS under the EPA and OECD structural definition. HexClad acknowledged coating its products with PTFE while simultaneously claiming they were PFAS-free, a position the lawsuit characterized as materially misleading. As a condition of the settlement, HexClad agreed to stop advertising products as "non-toxic," "PFOA-free," or "PFAS-free" if they contain PTFE or any other PFAS.
A separate lawsuit against Made In Cookware made similar allegations, arguing it was misleading to market cookware as "100% non-toxic" when the PTFE manufacturing process itself involves PFAS compounds.
These cases are not isolated incidents. They reflect a structural problem in the cookware marketing environment: brands discovered that PFAS anxiety among consumers was commercially exploitable, and some made claims that went well beyond what their products could actually support. The litigation is beginning to create accountability, but it is reactive -- it addresses false claims after consumers have already paid for products and believed they were making safer choices.
On March 25, 2025, NSF International announced the release of NSF Certification Guideline 537: PFAS-Free Products for Nonfood Compounds and Food Equipment Materials. This is the most significant development in PFAS-free claim verification to date, and it represents the first standardized third-party certification framework with a defined analytical methodology for confirming PFAS absence.
NSF 537 defines "PFAS-free" as any product that: - Does not contain intentionally added PFAS - Does not incorporate post-consumer recycled material or intentionally used PFAS additives - Has total organic fluorine (TOF) levels below 50 parts per million (ppm)
The 50 ppm TOF threshold matters because total organic fluorine analysis is the most sensitive available screening method for detecting PFAS as a class -- including the 10,000+ compounds that cannot all be individually tested. Organic fluorine is the chemical fingerprint of PFAS, so a TOF limit operationalizes the PFAS-free definition at the analytical level rather than relying solely on ingredient disclosure.
The certification process includes formulation review (confirming no intentionally added PFAS in ingredients), laboratory testing to the TOF threshold, and listing in NSF's verified databases. Certified food equipment materials appear in NSF's Certified Food Equipment listing; certified nonfood compounds are listed in the NSF White Book.
NSF 537 was designed primarily for commercial food equipment and food-industry chemical suppliers -- it is not a consumer product seal in the same direct sense as, say, MADESAFE. But it is the framework most likely to become the industry standard as state laws continue to push brands toward substantiated PFAS-free claims, and it gives procurement-minded families a specific question to ask: has this product been tested to NSF 537 or an equivalent analytical standard?
In the absence of federal PFAS-free claim standards, several states have moved to fill the regulatory gap -- both by banning PFAS in products outright and by restricting misleading chemical-free claims.
California AB 1200, effective January 2024, prohibits cookware manufacturers from claiming a product is free of a specific chemical if that chemical belongs to a chemical group identified on California's designated hazardous chemical list -- unless the chemical was genuinely not intentionally added. In practice, this means a brand cannot say "PFOA-Free" while using other PFAS. The law effectively requires PFAS-free claims to be class-wide, not compound-specific, or they cannot be made at all. It also requires manufacturers to disclose all intentionally added chemicals on product labels and websites.
Minnesota, as of January 1, 2025, became the first state to ban the sale of nonstick cookware with intentionally added PFAS coatings entirely, under Amara's Law (Minn. Stat. 116.943). The Minnesota Pollution Control Agency confirmed that air fryers are included in the cookware definition when they have a food contact surface with a nonstick PFAS coating. Beginning July 2026, companies selling products in Minnesota must disclose the presence of intentionally added PFAS. Minnesota's approach bypasses the claim verification problem entirely: if the product cannot be sold with PFAS, the PFAS-free claim becomes the only available marketing language -- and it had better be accurate.
Other states -- including Maine, Connecticut, New York, Washington, and Colorado -- have enacted or are advancing PFAS product restrictions with phased compliance timelines extending to 2032.
Not all PFAS-free claims are created equal. The spectrum ranges from marketing language with no backing to verified third-party testing with published results.
Most credible (third-party testing with published data):
Lower confidence (claim without substantiated public testing):
For air fryers specifically, the safest choices are stainless steel basket models (such as certain Breville configurations) or verified ceramic-coated models. The enclosed, fan-circulated environment of an air fryer makes PFAS-free verification particularly important: any coating degradation gets distributed throughout the cooking cavity more efficiently than in an open pan.
"Non-toxic" is the broadest and least regulated claim in the cookware space. It has no definition in US federal law, no required testing, and no enforcement mechanism. It is a pure marketing term. A product can simultaneously be labeled non-toxic and contain PTFE, and several brands have done exactly that, as the HexClad and Made In litigation illustrates.
The FTC's Green Guides, which govern environmental marketing claims, do provide general guidance that unsubstantiated environmental claims can constitute deceptive advertising -- but the FTC has not issued specific rules on PFAS-free or non-toxic claims for cookware. California's AB 1200 provides the strongest current state-level check on misleading non-toxic claims in the context of chemical class misrepresentation.
From a practical evaluation standpoint: treat "non-toxic" as a prompt to look deeper, not as a safety guarantee. Ask what the coating material is, whether independent testing has been done, what standard the testing used, and whether results are published.
Given the regulatory vacuum, here is a practical decision framework for families evaluating cookware, frying pans, air fryers, or any kitchen product making a PFAS-free claim:
Step 1: Identify the coating material. The brand should be able to tell you specifically what the nonstick surface is made from -- ceramic sol-gel, stainless steel, cast iron, carbon steel, or a named polymer. If a brand will not disclose the coating chemistry, the PFAS-free claim has no foundation.
Step 2: Confirm PTFE-free status. PTFE-free and PFAS-free should appear together. PTFE is the most common PFAS in cookware and the one most likely to be present. A brand that claims PFAS-free without mentioning PTFE may be using PTFE and not considering it a PFAS -- which is inconsistent with EPA and OECD definitions.
Step 3: Look for third-party testing. Caraway publishes third-party results. NSF 537 is the emerging standard for food equipment materials. MADESAFE certifies consumer products with an explicit PFAS screen. Ask whether the brand has engaged any third-party lab and whether results are accessible.
Step 4: Check for California AB 1200 disclosure compliance. Brands selling into California after January 2024 must disclose intentionally added chemicals on their websites. If a brand is compliant, their chemical disclosure page should be findable. The absence of disclosure is a warning sign.
Step 5: Default to material choices that are PFAS-free by chemistry. Stainless steel, cast iron, carbon steel, and enameled cast iron contain no fluoropolymers by design. For the situations where nonstick is genuinely needed, a third-party-tested ceramic coating from a brand that discloses its chemistry and testing is the next-best option.
This is not about achieving perfection. It is about making the evaluation with clear eyes, knowing that the label on the box is a marketing decision -- not a regulatory finding.
The PFAS-Free claim itself is not a health risk -- the underlying PFAS compounds it purports to exclude are the concern. When the claim is accurate and verified, it represents a meaningful reduction in exposure to a class of chemicals linked to cancer, immune suppression, thyroid disruption, and developmental harm. When the claim is misleading -- as in cases where PTFE-coated products were marketed as PFAS-free -- families may believe they have eliminated a risk that remains present.
The health relevance of evaluating these claims carefully is highest for: - Families using nonstick air fryers, where high heat and an enclosed fan-circulated cavity increase the likelihood that any PTFE degradation products are distributed throughout the cooking space - Households with pregnant women or young children, for whom PFAS exposure during critical developmental windows carries the most documented risk - Families replacing cookware and wanting to make a genuinely lower-exposure choice rather than a marketing-driven one
A false PFAS-free claim does not create new exposure beyond what a conventional PTFE-coated product would -- it simply fails to deliver the risk reduction the label promises.
Federal (US): No federal agency has defined "PFAS-Free" for marketing purposes as of March 2026. The FDA, EPA, and FTC have not issued rules specifically governing PFAS-free claims on cookware or kitchen appliances. The FTC's Green Guides (last updated 2012, revision pending) provide general deceptive advertising standards applicable to unsubstantiated environmental claims, but have not been applied directly to PFAS-free claims in enforcement actions to date.
California AB 1200 (effective January 2024): Prohibits cookware manufacturers from claiming a product is free of a specific chemical if the chemical belongs to a chemical class on the state's designated hazardous chemical list, unless the chemical was genuinely not intentionally added. This effectively bans "PFOA-Free" claims on products that still contain other PFAS. Also requires online and label disclosure of all intentionally added chemicals.
Minnesota (effective January 1, 2025): Banned sale of nonstick cookware with intentionally added PFAS under Amara's Law. Air fryers with PFAS-coated food contact surfaces are included. Mandatory PFAS disclosure reporting begins July 2026.
NSF 537 (launched March 25, 2025): The first standardized third-party certification for PFAS-free products in food equipment materials. Defines PFAS-free as no intentionally added PFAS and total organic fluorine below 50 ppm. Currently the most analytically rigorous third-party verification available, though designed primarily for commercial food industry suppliers rather than direct consumer product labeling.
EU: Under REACH, the European Chemicals Agency is evaluating a near-universal restriction on all PFAS compounds with Commission decisions expected 2027-2028. EU member state rules and ECHA guidance already impose stricter standards on PFAS claims in consumer products than US federal law.

No. As of March 2026, no federal agency has defined 'PFAS-free' for marketing purposes on cookware, air fryers, or other consumer products. The FDA, EPA, and FTC have not established a legal definition, testing requirement, or enforcement standard for the claim. California's AB 1200 is the most significant state-level constraint -- it prohibits brands from claiming freedom from a specific chemical if the product still contains others in the same chemical class -- but it does not create a verified PFAS-free standard either. NSF 537, launched in March 2025, is the first third-party certification that operationalizes the claim analytically, but it is not a federal or state regulatory requirement.
These are three different claims with very different implications. PFOA-free is the lowest bar: PFOA was phased out of US manufacturing by 2015, so almost all modern cookware qualifies. It does not mean the product is free of other PFAS. PTFE-free is a higher bar: PTFE is the fluoropolymer used in Teflon and most nonstick coatings, and it qualifies as a PFAS under EPA and OECD definitions. A product that is genuinely PTFE-free has removed the primary fluoropolymer. PFAS-free is the broadest claim, covering the entire class of 10,000+ compounds. The problem is that it is unregulated, so a product could theoretically be labeled PFAS-free while containing PTFE -- exactly what the HexClad lawsuit alleged.
NSF 537 is a certification guideline launched by NSF International in March 2025. It defines PFAS-free as no intentionally added PFAS and total organic fluorine (TOF) below 50 parts per million, verified through formulation review and laboratory testing. It is currently designed for food equipment materials and food-industry chemical suppliers rather than direct consumer retail products. However, it establishes the analytical standard that will likely influence how consumer-facing PFAS-free claims are verified going forward. When evaluating a brand's PFAS-free claim, asking whether the product has been tested to NSF 537 or an equivalent total organic fluorine standard is a useful benchmark.
In 2025, HexClad agreed to a $2.5 million class action settlement over allegations that it falsely marketed cookware as 'Non-Toxic, PFAS-Free' while the products contained PTFE -- a fluoropolymer that qualifies as a PFAS under EPA and OECD structural definitions. The lawsuit argued that coating a product with PTFE while labeling it PFAS-free was materially misleading. As part of the settlement, HexClad agreed to stop advertising products as non-toxic, PFOA-free, or PFAS-free if they contain PTFE or any other PFAS. The case illustrates how PFAS-free claims without adequate substantiation have created real legal exposure for brands.
True ceramic sol-gel coatings -- like GreenPan's Thermolon or the coatings used by Caraway and Our Place -- are PFAS-free by chemical structure. They are silica-based (essentially derived from sand) and contain no fluoropolymers. Consumer Reports tested ceramic-coated pans and found no detectable PFAS among 96 compounds screened. However, 'ceramic nonstick' is a marketing term with no legal definition, and some products labeled ceramic are hybrid formulations that include PTFE. Look for an explicit PTFE-free and PFAS-free statement combined with third-party test data. Caraway is the strongest current example of consumer-facing transparency in this space.
California's AB 1200, effective January 2024, prohibits cookware manufacturers from claiming a product is free of a specific chemical if that chemical belongs to a chemical class on California's designated hazardous chemical list -- unless the chemical genuinely was not intentionally added. This means a brand cannot say 'PFOA-Free' while using other PFAS compounds. It also requires manufacturers to disclose all intentionally added chemicals on product websites and physical labels. In practice, it prevents the most common form of PFAS marketing misdirection: singling out one phased-out compound while leaving the broader class unaddressed.
Minnesota's Amara's Law, effective January 2025, bans the sale of nonstick cookware with intentionally added PFAS -- including air fryers with PFAS-coated food contact surfaces. This effectively makes PTFE-coated nonstick cookware illegal to sell in Minnesota. However, it does not itself regulate or define PFAS-free claims; it simply removes the products those claims were being falsely applied to. Mandatory PFAS disclosure reporting for products sold in Minnesota begins July 2026, which will add a data layer. The ban is meaningful as a market mechanism but does not create a national verified-claim standard.
Four things, in order of reliability: First, disclosure of coating material -- the brand should specify whether the surface is ceramic sol-gel, stainless steel, cast iron, or a named polymer. Second, explicit PTFE-free status alongside any PFAS-free claim. Third, third-party lab test results published on the brand's website -- Caraway is the consumer benchmark for this. Fourth, California AB 1200 chemical disclosure compliance, which requires publicly accessible ingredient lists for brands selling into California. Stainless steel, cast iron, carbon steel, and enameled cast iron are PFAS-free by material -- for these options, no coating verification is needed.
