# PFOA-Free vs PFAS-Free: What's the Difference?

> PFOA-free and PFAS-free are not the same claim -- not even close. PFOA was phased out of US cookware manufacturing by 2015, so virtually every nonstick pan and air fryer sold today already qualifies as 'PFOA-free.' It can still contain PTFE, GenX, and thousands of other PFAS compounds. Understanding the difference between these two labels is the single most important skill for buying safer cookware.

## Reality Check

**Claim:** My air fryer says PFOA-free so it doesn't have any forever chemicals
**Reality:** PFOA-free means one specific forever chemical -- phased out of US manufacturing in 2015 -- is not present. The basket is almost certainly coated with PTFE, which is a PFAS under EPA and OECD structural definitions. GenX, the compound now used to manufacture PTFE, is also a PFAS. 'PFOA-free' on a 2024 air fryer is as meaningful as 'lead-paint-free' on a 2024 house -- it describes the universal baseline, not a safety distinction.

## Overview

Walk through a kitchen store -- or scroll through an air fryer listing on Amazon -- and you will see "PFOA-Free" displayed prominently on boxes from Tefal, Calphalon, Cuisinart, and dozens of others. Depending on where you look, the same products might also be labeled "PFAS-Free." These two phrases look related. They feel like they belong to the same family of safety claims. Brands deploy them side by side, often without distinction.

They are not the same. One of them has been effectively meaningless since 2015. The other is the only one worth evaluating. And the gap between them is exactly where the most common cookware greenwashing lives.

If you have ever wondered whether your "PFOA-free" [air fryer](/category/air-fryer) is actually safe from [PFAS](/learn/ingredients/pfas), this is the piece that answers the question.

## What PFOA-Free Actually Means in 2026

[PFOA (perfluorooctanoic acid)](/learn/ingredients/pfoa) is a specific member of the PFAS family -- an 8-carbon acid that DuPont and 3M used for decades as a processing aid in manufacturing [PTFE (Teflon)](/learn/ingredients/ptfe-teflon) coatings. PFOA made the slippery polymer stick to metal during production. It also turned out to be a confirmed human carcinogen (WHO IARC Group 1, December 2023), with the strongest documented links to kidney cancer and testicular cancer.

When that became undeniable through the C8 lawsuits against DuPont and the resulting 69,000-person C8 Health Project, the EPA launched a voluntary phase-out program. Eight major manufacturers committed to eliminating PFOA from US production. By 2015, the phase-out was complete.

This is the fact that makes "PFOA-free" essentially useless as a safety claim today: **virtually every nonstick product manufactured in the United States since 2015 is already PFOA-free**. It describes the universal baseline of modern cookware production, not a distinguishing safety feature. A brand printing "PFOA-free" on a box in 2026 is telling you they complied with an industry-wide standard that took effect more than a decade ago.

This does not mean PFOA is not a concern. If you own cookware or an air fryer with a PTFE basket purchased before 2013 to 2015, the coating was manufactured using PFOA as a processing aid, and residual PFOA may remain -- particularly if the coating is scratched or worn. Pre-2015 pans with visible coating damage are a genuine exposure concern. Post-2015 pans labeled PFOA-free are not meaningfully safer than any other post-2015 pan: the claim describes a shared property of the entire product category.

## What PFAS-Free Actually Means

[PFAS (per- and polyfluoroalkyl substances)](/learn/ingredients/pfas) is not a single chemical. It is a family of more than 10,000 synthetic compounds, all built on the same extraordinarily stable carbon-fluorine bond. PFOA is one member of that family. PTFE is another. GenX is another. PFBS, PFHxA, PFOS, and thousands of additional compounds with varying chain lengths and functional groups all belong to the PFAS class.

A product that is genuinely PFAS-free contains none of them -- not PFOA, not PTFE, not GenX, not any of the 10,000-plus compounds the EPA and OECD include under the structural definition of PFAS.

That is a fundamentally different and much higher standard than removing a single phased-out processing acid from a product that still uses a fluoropolymer coating. And that gap -- between eliminating one specific PFAS and eliminating the class -- is the gap that brands have learned to exploit.

## Why PFOA-Free Cookware Can Still Contain PTFE

Here is the confusion that costs families the most: [PTFE (polytetrafluoroethylene)](/learn/ingredients/ptfe-teflon) is the polymer that makes Teflon and generic nonstick coatings slippery. PFOA was historically used to manufacture PTFE, but PTFE and PFOA are not the same compound. You can remove PFOA from the manufacturing process while leaving the PTFE coating entirely intact. That is exactly what the 2015 phase-out accomplished.

Under the EPA's structural definition and the OECD's definition of PFAS (ENV/CBC/MONO(2021)25), PTFE qualifies as a PFAS. It is a fully fluorinated polymer -- every carbon-hydrogen bond replaced by a carbon-fluorine bond -- which is the defining structural feature of the PFAS class. The EPA has included high-molecular-weight fluoropolymers like PTFE within the PFAS umbrella in its regulatory framework since at least 2021.

This means a product can be simultaneously:
- PFOA-free (the processing acid was removed in 2015)
- Still coated with PTFE (the fluoropolymer is still there)
- Not PFAS-free (PTFE is a PFAS)

When a brand labels a PTFE-coated air fryer basket or frying pan "PFOA-free," every word of that claim may be technically accurate. And the product is still not PFAS-free. That is not a technicality. It is the entire marketing strategy.

## The GenX Problem: When You Replace One PFAS With Another

After PFOA was phased out, PTFE manufacturers needed a replacement processing aid. DuPont (later spun off as Chemours) developed GenX (chemical name HFPO-DA, hexafluoropropylene oxide-dimer acid) specifically for this purpose. GenX is shorter-chain than PFOA, which means it does not bioaccumulate as readily in blood. But it is still a PFAS.

Early animal toxicology data on GenX shows liver toxicity and immune effects. GenX has contaminated drinking water near the Chemours plant in Fayetteville, North Carolina, at concentrations that triggered health advisories. The EPA's April 2024 drinking water rule covered GenX at 10 parts per trillion -- a standard that acknowledges its toxicity is a real concern, not a theoretical one.

The GenX story is why [PFAS-free certifications](/learn/concepts/pfas-free-claim) have moved toward testing total organic fluorine (TOF) rather than testing for specific named compounds. When you screen for TOF, you catch compounds that have not yet been individually identified or named. When you screen for specific compounds by name, manufacturers can switch to a structurally similar replacement that is not yet on the list. GenX is the most documented example of that replacement pattern, but it is not the only one.

"PFOA-free" on a post-2015 product means PFOA was removed. It says nothing about whether GenX is present in the PTFE manufacturing process, at what concentrations, or whether it migrates into food during cooking.

## The Label Hierarchy for Families

Three claims appear on nonstick cookware and [air fryer](/category/air-fryer) products. They are not equivalent. From lowest to highest protective value:

**PFOA-free:** The floor, not the ceiling. Since 2015, this describes every modern US-manufactured nonstick product. It excludes one chemical that was phased out a decade ago. It says nothing about PTFE, GenX, or the rest of the PFAS class. Treat it as a baseline, not a safety feature.

**PTFE-free:** A meaningfully higher bar. PTFE is the dominant PFAS in nonstick cookware. A product that is genuinely PTFE-free -- using ceramic sol-gel, stainless steel, or cast iron instead -- has removed the primary fluoropolymer source. However, PTFE-free alone does not guarantee freedom from all PFAS: manufacturing aids or solvents used to apply a non-PTFE coating could theoretically contain PFAS if not independently tested.

**PFAS-free (with verified testing):** The claim that matters -- when it is backed up. "PFAS-free" as a label alone has no federal legal definition in the United States. No FDA or EPA rule requires testing before a brand makes the claim. But "PFAS-free" combined with third-party testing to total organic fluorine limits, or certification under NSF 537, is the highest-confidence claim available to consumers today.

The practical read: if a product says "PFOA-free" and nothing else, that is a prompt to look harder. If a product says "PFAS-free" with no supporting data or certification, the claim has no more legal weight than the PFOA-free label. If a product says "PFAS-free AND PTFE-free" with published third-party test results, that is a substantiated claim worth taking seriously.

## How This Plays Out on Real Products

The difference between PFOA-free and PFAS-free is not abstract -- it maps directly onto specific brand choices in the cookware and air fryer markets.

**Tefal (T-fal):** Tefal explicitly markets many of its products as "PFOA-free" and uses PTFE nonstick coatings as its primary cooking surface technology. The PFOA-free claim is accurate for post-2015 products. The product still contains PTFE. It is not PFAS-free under the EPA's structural definition. Tefal has not published third-party PFAS testing or certified to NSF 537.

**Cuisinart and other mainstream brands:** The same pattern applies. Most mainstream nonstick cookware brands use PTFE coatings and market them as PFOA-free. This is legally accurate and substantively incomplete. The PFAS class is still present in the coating.

**GreenPan (Thermolon ceramic):** GreenPan's Thermolon coating is a ceramic sol-gel -- silica-based, with no fluoropolymer component. It is PFAS-free by chemical structure. Consumer Reports tested GreenPan ceramic pans and found no detectable PFAS among 96 compounds screened. However, GreenPan stopped publishing test data publicly after 2020, settled a 2019 class action over marketing practices, and no longer maintains the same level of third-party transparency that Caraway and Our Place do. The claim remains chemically credible but less verifiable than it once was.

**Caraway:** Explicitly PTFE-free and PFAS-free, backed by third-party lab testing for over 200 harmful substances with results published on the brand's website. Compliant with California AB 1200 disclosure requirements. The current consumer benchmark for claim transparency in ceramic cookware.

**Our Place (Always Pan, Wonder Oven):** Ceramic coating explicitly stated as PFAS-free and PTFE-free. The Wonder Oven markets itself as a PFAS-free [air fryer](/category/air-fryer) alternative with third-party backing. Consistently cited alongside Caraway as the most transparent brands in the ceramic cookware space.

**HexClad (cautionary case):** In 2025, HexClad agreed to a $2.5 million class action settlement over allegations that it labeled PTFE-coated cookware as "Non-Toxic, PFAS-Free." The lawsuit argued that marketing a PTFE-containing product as PFAS-free was materially misleading. As a settlement condition, HexClad agreed to stop making PFAS-free or non-toxic claims on products containing PTFE. This case is the clearest illustration of what happens when the PFOA-free/PFAS-free confusion is deliberately exploited in marketing.

## What NSF 537 Changed

On March 25, 2025, NSF International launched Certification Guideline 537: PFAS-Free Products for Nonfood Compounds and Food Equipment Materials. This is the first standardized third-party certification with a defined analytical methodology for PFAS-free verification.

NSF 537 defines PFAS-free as:
- No intentionally added PFAS
- No post-consumer recycled material or intentionally used PFAS additives
- Total organic fluorine (TOF) below 50 parts per million

The TOF threshold matters because it tests for the chemical fingerprint of PFAS as a class, not individual compounds by name. A 50 ppm TOF limit catches compounds that have not yet been individually identified -- including potential GenX successors that have not yet been registered or studied. It is structurally immune to the replacement-chemical loophole.

NSF 537 was designed primarily for commercial food equipment suppliers rather than direct consumer retail products. But it sets the analytical standard that any credible PFAS-free claim for a food-contact product should aspire to meet. When evaluating a brand's PFAS-free claim, the right question to ask is: has this product been tested to NSF 537 or an equivalent total organic fluorine standard? A brand that answers yes and can direct you to the results is in a different category than a brand that prints the claim on a box.

## Air Fryers Deserve Extra Scrutiny

The PFOA-free vs PFAS-free distinction is important for all cookware. For [air fryers](/category/air-fryer), it is especially important.

Air fryers operate differently from open pans. The enclosed cooking cavity, the high-speed fan, and the high-heat convection environment mean that anything released from a coating surface gets circulated throughout the entire cooking space and into the air around the appliance -- not just rising from an open pan surface. PTFE begins degrading at 260 degrees Celsius (500 degrees Fahrenheit), and air fryer preheating can push basket surface temperatures toward or past that threshold before food is added as a thermal buffer.

A scratched PTFE basket in an air fryer is a higher-risk scenario than a scratched pan on a stovetop, for exactly this reason: the degradation products are distributed through the cooking environment by the fan rather than dispersing into open kitchen air. The enclosed-cavity, fan-circulated design is also why PTFE fume toxicity is especially dangerous for pet birds kept near air fryers -- a consideration documented in veterinary literature.

This means the PFOA-free label on an air fryer basket is doing less work than it appears to. The enclosed operating environment makes PFAS-free verification -- including third-party confirmation that no PTFE is present -- a meaningfully higher priority than it would be for a simple stovetop pan.

For stainless steel basket air fryer models (certain Breville configurations, for example), no coating verification is needed: stainless steel is PFAS-free by material. For ceramic-coated models from Our Place, the PFAS-free claim is backed by explicit brand disclosure and third-party alignment. For any air fryer labeled only "PFOA-free" without a PFAS-free or PTFE-free statement, the coating is almost certainly PTFE.

## How to Read a Label Without Getting Fooled

Here is a practical framework for any nonstick cookware or [air fryer](/category/air-fryer) purchase:

**Step 1: Find the coating material.** The brand should be able to tell you specifically what the cooking surface is: ceramic sol-gel, stainless steel, cast iron, carbon steel, or a named polymer like PTFE/polytetrafluoroethylene. If the brand will not disclose the coating chemistry, no PFAS-free claim resting on that product has any foundation.

**Step 2: Confirm PTFE-free status.** Look for the words "PTFE-free" or "polytetrafluoroethylene-free" stated explicitly -- not just "Teflon-free" (Teflon is a brand name; generic PTFE is the same compound). A brand that claims PFAS-free without explicitly addressing PTFE may be operating under a definition of PFAS that excludes high-molecular-weight fluoropolymers -- an exclusion that is inconsistent with EPA and OECD structural definitions.

**Step 3: Look for third-party testing.** The brand should be able to direct you to published test results. Caraway publishes its third-party lab results on its website. NSF 537 certification is searchable at nsf.org. MADESAFE certification involves an explicit PFAS screen. A brand that references "independent testing" without providing access to the results is not meeting the same standard.

**Step 4: Check for California AB 1200 compliance.** California's AB 1200, effective January 2024, requires brands to disclose all intentionally added chemicals on product websites and packaging. A brand compliant with AB 1200 should have a publicly accessible chemical disclosure. The absence of that disclosure for a brand selling into California is a warning sign.

**Step 5: Default to materials that are PFAS-free by chemistry.** Stainless steel, cast iron, carbon steel, and enameled cast iron contain no fluoropolymers by design. For situations where nonstick is genuinely needed, a third-party-tested ceramic coating from a brand with transparent chemistry disclosure is the next-best option. You do not need to achieve perfection -- you need to be making the evaluation with accurate information, not marketing language.

## Health Concerns

The core health concern behind this distinction is the gap between what the PFOA-free label implies and what it actually means. When families buy a product labeled PFOA-free believing it is free of all PFAS, and it contains PTFE or GenX, they have not made the exposure reduction they intended. The health relevance of closing that gap is real:

**PTFE in PFAS-free context:** Under EPA and OECD structural definitions, PTFE is a PFAS. At normal cooking temperatures below 260 degrees Celsius, intact cured PTFE is considered biologically inert -- the polymer does not migrate into food in measurable amounts. The concern activates at higher temperatures (PTFE degradation begins at 260 degrees Celsius) and with physical damage (scratched coatings release significantly more particles). For [air fryers](/category/air-fryer), which can push surface temperatures toward PTFE degradation thresholds during empty preheating, and which circulate any released particles through an enclosed cooking cavity, the risk profile of a PTFE-coated basket is higher than a stovetop pan.

**GenX exposure through PTFE manufacturing:** Even a product that qualifies as PFOA-free may involve GenX in the PTFE manufacturing process. Early animal toxicology shows liver and immune effects. The EPA set a drinking water limit for GenX at 10 ppt in its 2024 rule -- a level that acknowledges real health concern, not precaution alone.

**The false-safety problem:** Families with pregnant women, infants, or young children at home are the population for whom PFAS-free verification matters most. PFAS cross the placenta, are transferred in breast milk, and are linked to immune suppression in children at blood concentrations overlapping the current US population range. A PFOA-free label that obscures ongoing PTFE or GenX exposure does not protect this population -- it creates false confidence while leaving the relevant exposure pathway open.

## Regulatory Status

**Federal (US):** There is no federal legal definition for either 'PFOA-free' or 'PFAS-free' as marketing claims on cookware or kitchen appliances as of March 2026. The FDA, EPA, and FTC have not established testing requirements, definitions, or enforcement standards for either claim on consumer products. The FTC's Green Guides (last revised 2012, revision pending) provide general deceptive advertising standards applicable to unsubstantiated claims, but have not been directly enforced on cookware PFAS claims. PFOA itself was phased out under a voluntary manufacturer stewardship program (not a regulatory mandate), which is why the resulting 'PFOA-free' claim on modern products has no regulatory teeth -- it describes compliance with a decade-old voluntary commitment.

**California AB 1200 (effective January 2024):** Prohibits cookware brands from claiming a product is free of a specific chemical if the chemical belongs to a hazardous chemical class identified on California's designated list -- unless the chemical genuinely was not intentionally added. This effectively bars 'PFOA-free' claims on products containing other PFAS, because PFOA belongs to the PFAS class listed under California's hazardous chemicals designation. Also requires disclosure of all intentionally added chemicals on product websites and physical labels.

**Minnesota (effective January 1, 2025):** Banned sale of nonstick cookware with intentionally added PFAS under Amara's Law (Minn. Stat. 116.943). Air fryers with PFAS-coated food contact surfaces are included. PFAS disclosure reporting for products sold in Minnesota 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 highest-credibility analytical verification available, designed initially for commercial food equipment suppliers.

**EU:** The European Chemicals Agency is evaluating a near-universal PFAS restriction under REACH, with Commission decisions expected 2027-2028. Several EU member states have already moved faster via national measures.

## Label Guide

**Look for:**
- PFAS-free AND PTFE-free stated together -- the highest combined claim for nonstick cookware or air fryers
- NSF 537 certification -- the only standardized third-party PFAS-free verification for food equipment materials as of 2025
- Third-party lab test results published on the brand's website -- Caraway is the current consumer benchmark for this level of transparency
- California AB 1200 chemical disclosure compliance -- publicly accessible chemical list on brand website
- Ceramic sol-gel coating specified by name (Thermolon, etc.) -- PFAS-free by chemical structure
- Stainless steel basket or cooking surface -- PFAS-free by material, no coating verification needed
- MADESAFE certification -- screens explicitly for PFAS across consumer product categories

**Avoid / misleading:**
- PFOA-free without PFAS-free or PTFE-free -- excludes one 2015-phased-out compound from a class of 10,000+; effectively meaningless on modern products
- Non-toxic without coating material disclosure -- legally undefined, unverified, and the language used in the HexClad PFAS class action settlement
- Diamond, granite, titanium, or stone nonstick -- typically PTFE coatings with mineral-themed branding; PFOA-free but not PFAS-free
- PFAS-free on a product that also lists PTFE or polytetrafluoroethylene in its materials -- a direct contradiction illustrated by the HexClad case
- Teflon-free without PTFE-free -- Teflon is a brand name; generic PTFE is the same polymer
- PFAS-free with no published test data, certification, or coating disclosure -- a label claim with no verifiable foundation

## Look For Instead

- Stainless steel basket air fryers (Breville Smart Oven configurations)
- Our Place Wonder Oven -- ceramic-coated, explicitly PTFE-free and PFAS-free with third-party backing
- Caraway cookware -- PTFE-free, PFAS-free, third-party tested with results published on brand website
- Cast iron, carbon steel, or enameled cast iron cookware -- PFAS-free by material composition
- GreenPan Thermolon ceramic -- PFAS-free by chemical structure; Consumer Reports testing confirmed no detectable PFAS (note: less publicly transparent than Caraway since 2020)

## Who Is At Risk

- Parents choosing air fryers or nonstick cookware based on PFOA-free labeling, believing it confers the same protection as PFAS-free
- Pregnant women and families with young children for whom PFAS developmental exposure carries documented risk during fetal and infant development
- Consumers in states without California AB 1200 or Minnesota Amara's Law protections, where the federal regulatory vacuum leaves PFAS-free claims entirely unverified
- Anyone using a scratched or heavily worn PTFE-coated air fryer basket believing it is PFAS-free based on packaging language
- Households with pet birds kept near air fryers -- PTFE fume toxicity is well-documented in avian veterinary literature at basket temperatures above 280 degrees Celsius

## Common Triggers In Products

- PTFE (polytetrafluoroethylene) nonstick coating -- the primary PFAS in modern cookware, present regardless of PFOA-free labeling
- GenX (HFPO-DA) -- used as PFOA replacement in PTFE manufacturing since ~2015; a PFAS with emerging toxicity concerns
- Marketing terms like 'diamond,' 'granite,' 'titanium,' or 'stone' nonstick -- these describe PTFE base coatings with mineral-themed branding, not alternative coating materials
- Scratched or worn PTFE basket surfaces -- dramatically increase PFAS particle release in air fryer and cookware contexts

## Product Categories To Avoid

- Air fryers with PTFE-coated baskets labeled only PFOA-free (Ninja, Cosori, Instant Vortex standard models)
- Mainstream nonstick cookware lines (Tefal/T-fal, standard Cuisinart, standard Calphalon) labeled PFOA-free without PFAS-free backing
- Any cookware or air fryer basket with visible scratching, chipping, or flaking nonstick coating
- Products labeled PFAS-free or non-toxic that include PTFE in materials specifications (as illustrated by the HexClad settlement)

## What Helps

Choosing cookware and air fryers with coating materials that are PFAS-free by chemistry -- ceramic sol-gel, stainless steel, cast iron, carbon steel, or enameled cast iron -- removes the PTFE and GenX variables entirely without requiring any label interpretation. For situations where nonstick performance is a priority, a ceramic-coated product from a brand with published third-party test results (Caraway, Our Place) provides the highest-confidence combination of performance and verified PFAS-free status currently available to consumers.

## When To See A Doctor

If you are pregnant and have reason to believe you have had significant PFAS exposure through contaminated water or pre-2015 cookware, discuss PFAS blood serum testing with your OB or midwife. The National Health and Nutrition Examination Survey (NHANES) methodology uses standard serum PFAS panels. No clinical intervention currently reverses PFAS body burden, but the assessment can inform decisions about water filtration and cookware replacement priorities during the critical first-trimester window.

## How To Verify

For cookware and air fryers: ask the brand for access to third-party lab test results showing total organic fluorine (TOF) below detection limits -- not just a PFOA-free or PFAS-free statement. NSF 537 certification is searchable at nsf.org. Caraway publishes results at carawayhome.com/third-party-testing. For California AB 1200 disclosure, search the brand name plus 'AB 1200 chemical disclosure' -- compliant brands have a public page. Consumer Reports has published independent PFAS testing of cookware brands including GreenPan, Caraway, and several mainstream brands -- their findings are publicly accessible and do not require a subscription for summary results.

**Effective Date:** 2015

## Timeline

- **1938:** PTFE Discovered — DuPont chemist Roy Plunkett accidentally discovers polytetrafluoroethylene (PTFE). PFOA begins to be used as a processing aid in manufacturing the polymer into Teflon coatings by the 1950s.
- **1999-2015:** C8 Litigation and PFOA Phase-Out — Attorney Rob Bilott files the first lawsuit against DuPont over PFOA contamination near the Parkersburg, WV plant. The C8 Health Project enrolls 69,000 people. EPA launches the voluntary PFOA Stewardship Program. By 2015, eight major manufacturers complete the phase-out -- making 'PFOA-free' the universal baseline for new US cookware.
- **2015-2016:** PFOA-Free Becomes a Marketing Term — With PFOA removed from US manufacturing, brands begin prominently labeling products 'PFOA-free.' The claim is technically accurate but substantively meaningless: all modern products share the property. PTFE coatings and GenX replacement processing aids remain in production.
- **December 2023:** PFOA Classified Group 1 Carcinogen — WHO's International Agency for Research on Cancer (IARC) upgrades PFOA to Group 1 -- confirmed human carcinogen -- based on sufficient evidence of kidney and testicular cancer in human populations. The classification increases public scrutiny of PFAS in cookware, driving demand for PFAS-free claims.
- **January 2024:** California AB 1200 Takes Effect — California prohibits cookware brands from claiming freedom from a specific chemical if the product contains other chemicals in the same hazardous class. 'PFOA-free' claims on PTFE-coated products are effectively prohibited in California when not accompanied by full class disclosure.
- **February 2025:** HexClad $2.5M PFAS Settlement — HexClad agrees to a $2.5 million class action settlement over claims it labeled PTFE-coated cookware as 'Non-Toxic, PFAS-Free.' As a condition, HexClad must stop making PFAS-free or non-toxic claims on products containing PTFE -- establishing a legal precedent for the PTFE/PFAS-free distinction.
- **January 2025:** Minnesota Bans PFAS Cookware — Minnesota becomes the first US state to ban sale of nonstick cookware with intentionally added PFAS, including air fryers with PFAS-coated food contact surfaces. Mandatory PFAS disclosure reporting begins July 2026.
- **March 25, 2025:** NSF 537 Launches — NSF International launches the first standardized PFAS-free certification for food equipment materials. NSF 537 defines PFAS-free as no intentionally added PFAS and total organic fluorine below 50 ppm -- operationalizing the claim analytically rather than relying on brand self-certification.

## Air Fryers: Why the Enclosed Design Raises the Stakes

An air fryer is not just a hot pan. The high-speed fan and enclosed cooking cavity mean that anything released from a PTFE coating during cooking gets distributed throughout the cooking space and into kitchen air -- not just rising from an open surface. Empty preheating can push basket surface temperatures toward the PTFE degradation threshold before food is added as a thermal buffer. For families using nonstick air fryer baskets labeled only PFOA-free, this enclosed circulation effect makes the PTFE-vs-PFAS-free distinction more consequential than it would be for a stovetop pan. The safest verification for an air fryer basket is the same as for any cookware: PTFE-free and PFAS-free stated together, with published test results or stainless steel material confirmation.

## What This Does Not Cover

Even a verified PFAS-free claim on cookware does not address PFAS exposure through drinking water, food packaging, or other household sources. For families concerned about total PFAS body burden -- particularly pregnant women, infants, and young children -- cookware is one exposure pathway, not the only one. Drinking water filtration with NSF/ANSI 58-certified reverse osmosis or NSF 53/P473-certified carbon block systems is the highest-impact single action for most households. PFAS-free cookware verification also does not eliminate PFAS already present in the body from prior exposure -- it reduces ongoing intake.

## R3 Bottom Line

- PFOA was phased out of US cookware manufacturing by 2015 -- every modern nonstick product qualifies as PFOA-free, which means the label tells you almost nothing about PFAS exposure in the products you are buying today
- PTFE is a PFAS under EPA and OECD structural definitions -- 'PFOA-free' cookware with a PTFE coating is not PFAS-free, and GenX (the replacement processing aid used in PTFE manufacturing) carries its own emerging toxicity concerns
- The claim that actually matters is 'PFAS-free AND PTFE-free' stated together, backed by third-party testing to total organic fluorine limits -- without both elements, the claim is a marketing label, not a verified safety property
- NSF 537 (launched March 2025) is the credible third-party standard -- it requires TOF testing below 50 ppm and formulation review, covering compounds that have not yet been individually named or studied
- For air fryers specifically, the enclosed fan-circulated cooking cavity makes PTFE-free verification a higher priority than for open stovetop pans -- stainless steel baskets and third-party-tested ceramic models are the options with genuine PFAS-free status

## FAQ

### Is PFOA-free the same as PFAS-free?

No -- and this is the most important distinction in cookware label reading. PFOA is one specific PFAS compound that was phased out of US manufacturing by 2015. 'PFOA-free' describes a property shared by virtually every modern nonstick pan and air fryer sold in the US -- it was the universal industry baseline long before most brands started printing it on boxes. The product almost certainly still contains PTFE, which qualifies as a PFAS under EPA and OECD structural definitions, and may involve GenX (the PFOA replacement) in its manufacturing process. 'PFAS-free' is the broader claim covering the entire class of 10,000+ compounds -- and it is the only claim worth evaluating, provided it is backed by third-party testing.

### If PFOA was phased out in 2015, why does PFOA-free still appear on new products?

Because it still resonates with consumers who are aware of PFOA's toxicity concerns and do not know that the phase-out has made the claim universal. Brands include 'PFOA-free' on packaging because it creates a sense of safety credibility, not because it conveys safety information that distinguishes their product from competitors. A 2026 product labeled 'PFOA-free' is telling you it complied with an industry-wide commitment made over a decade ago. All products in the same category share that property. If the label stops at 'PFOA-free' without addressing PTFE or broader PFAS class membership, that absence is the relevant signal.

### Is PTFE the same as Teflon?

PTFE (polytetrafluoroethylene) is the chemical compound; Teflon is the DuPont/Chemours brand name for PTFE. Functionally, they are the same material. Labeling a product 'Teflon-free' without also stating 'PTFE-free' does not exclude generic PTFE from other manufacturers. Look specifically for 'PTFE-free' or 'polytetrafluoroethylene-free' in the product description.

### Does PTFE-free mean PFAS-free?

PTFE-free is a much higher bar than PFOA-free and gets you closer to PFAS-free, but it is not identical. PTFE is the most common PFAS in nonstick cookware, so removing it removes the primary fluoropolymer exposure source. However, a non-PTFE coating could theoretically involve PFAS processing aids or solvents in its application if not independently verified. 'PTFE-free' combined with 'PFAS-free' and third-party test results is the complete picture. Ceramic sol-gel coatings (like those used by GreenPan, Caraway, and Our Place) are PFAS-free by chemical structure -- silica-based with no fluoropolymers.

### What is GenX and why does it matter?

GenX (chemical name HFPO-DA) is the compound DuPont developed to replace PFOA in PTFE manufacturing after the 2015 phase-out. It is a PFAS. It is shorter-chain than PFOA, so it does not bioaccumulate in blood as readily, but early animal studies show liver toxicity and immune effects. The EPA included GenX in its April 2024 drinking water rule at 10 parts per trillion, acknowledging real health concern. GenX contaminated drinking water near the Chemours manufacturing plant in Fayetteville, North Carolina. A product that is PFOA-free but made with PTFE manufactured using GenX has swapped one PFAS processing chemical for another -- the 'PFOA-free' label tells you none of this.

### What is NSF 537 and how does it relate to PFAS-free cookware?

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. The TOF testing approach matters because it detects PFAS as a class rather than testing for named compounds individually -- which means it catches replacement chemicals like GenX successors that have not yet been formally registered. NSF 537 was designed for commercial food equipment materials and suppliers rather than direct consumer retail products, but it establishes the analytical standard that any credible consumer-facing PFAS-free claim should aspire to meet.

### Which air fryer brands are actually PFAS-free?

The safest option by material is any air fryer with a stainless steel basket -- stainless steel is PFAS-free by material composition, no coating verification needed. Certain Breville Smart Oven configurations use stainless steel interiors. For ceramic-coated air fryers, Our Place's Wonder Oven is the most cited verified option, with an explicit PTFE-free and PFAS-free claim backed by third-party alignment. Most mainstream air fryer brands (Ninja, Cosori, Instant Vortex) use PTFE-coated baskets and label them 'PFOA-free' -- accurate on the narrow claim, not PFAS-free under the broader standard.

### What happened with the HexClad lawsuit?

In 2025, HexClad agreed to a $2.5 million class action settlement over allegations it falsely marketed PTFE-coated cookware as 'Non-Toxic, PFAS-Free.' The lawsuit alleged that labeling a product as PFAS-free while it contained PTFE -- a PFAS under EPA and OECD structural definitions -- was materially misleading. As a settlement condition, HexClad agreed to stop making PFAS-free, non-toxic, or PFOA-free claims on products containing PTFE. The case is the clearest legal illustration of how the PFOA-free vs PFAS-free confusion gets weaponized in marketing, and what happens when courts are asked to evaluate it.

### How does California AB 1200 address this labeling problem?

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 hazardous chemical class on California's designated list -- unless the chemical genuinely was not intentionally added. Because PFOA belongs to the PFAS class, a brand cannot legally market a PTFE-containing product as 'PFOA-free' in California without also disclosing the presence of other PFAS. The law also requires brands to publish the full list of intentionally added chemicals on their websites and product labels. This disclosure requirement is the most useful proxy consumers outside California can use: if a brand selling nationwide has an AB 1200 chemical disclosure page, it is operating under a higher transparency standard.

### Should I throw out my current nonstick air fryer?

If the basket has visible scratches, chips, or coating flaking, replacing it reduces exposure regardless of how old it is -- physical damage significantly increases the release of PTFE particles and any residual processing compounds. For intact post-2015 PTFE baskets, the risk at normal cooking temperatures is lower but not zero. The practical approach most families take: replace the basket or the appliance when it shows visible wear, avoid empty preheating (which can spike surface temperatures toward the PTFE degradation threshold), and choose a stainless steel or verified ceramic-basket replacement when the time comes.
