PFAS-free cookware: what actually counts (and what's marketing)

August 6, 2026

"PFAS-free" has become the most valuable phrase in cookware marketing, which is exactly why it needs reading carefully. It appears on pans that qualify, on pans that don't, and on pans where the claim is technically true of one component and quietly untrue of another.

Here are the definitions, the regulatory position as it actually stands, and a way to check any brand's claim in under a minute. Including ours.

What PFAS actually means

PFAS stands for per- and polyfluoroalkyl substances. It is not one chemical. It's a family, and a very large one.

The working definition most regulators now use came out of an OECD review in 2021: a PFAS is a fluorinated substance containing at least one fully fluorinated methyl or methylene carbon atom. That's a structural test, not a toxicity test — it describes a shape of molecule, not a level of harm. Under it, the family runs to thousands of substances, from small mobile acids like PFOA through to large solid polymers.

The reason it gets regulated as a class is persistence. The carbon–fluorine bond is one of the strongest in organic chemistry, which is precisely what makes these materials useful and precisely why they don't break down. Hence "forever chemicals."

The part the label leaves out: PTFE is a PFAS

This is the single fact that resolves most of the confusion.

PTFE — polytetrafluoroethylene, sold under trade names including Teflon — is a fluoropolymer, and fluoropolymers sit inside the PFAS family under the OECD definition. Industry argues, with some reasonable grounds, that large polymers behave very differently from the small mobile acids that have contaminated water supplies: they're inert, they don't migrate readily, and they aren't absorbed. That's a legitimate argument about risk. It is not an argument that PTFE isn't a PFAS.

Regulators have been explicit. Minnesota's Amara's Law banned intentionally added PFAS in eleven product categories, cookware included, from 1 January 2025. The state's own guidance leaves no room for interpretation: it names Teflon as a trade name for PTFE, states plainly that PTFE is a member of the PFAS family, and confirms it is therefore prohibited in cookware sold there.

So a PTFE-coated pan advertised as PFAS-free is either using a narrower definition than the regulator does, or describing something other than the cooking surface. Worth asking which.

"PFOA-free" is a 2006 answer to a 2026 question

PFOA is one specific compound in the family, and it was genuinely a problem. In 2006 the US EPA invited eight major manufacturers into a stewardship programme committing them to cut PFOA emissions and product content by 95% by 2010 and eliminate them by 2015. The participants complied.

Which means "PFOA-free" on a pan sold today tells you very little. It describes an industry-wide baseline that has held for over a decade. It doesn't tell you whether the pan is PTFE-free, whether the coating uses a replacement fluorochemistry such as GenX, or whether anything else in the family is present. It's a true statement that isn't an answer to the question most people are asking when they read it.

What the regulators have actually decided

The European Food Safety Authority set a group tolerable weekly intake in 2020 of 4.4 nanograms per kilogram of body weight for four PFAS combined — PFOA, PFOS, PFNA and PFHxS — with effects on the immune system identified as the most critical endpoint. That's a limit for the whole diet, not a cookware standard, but it indicates the scale regulators are working at.

At EU level, five member states proposed a universal PFAS restriction under REACH. As of March 2026 the Risk Assessment Committee has issued its final opinion and the Socio-Economic Analysis Committee its draft opinion, both supporting an EU-wide restriction subject to specific derogations, with consultation still running.

And here's the counterweight, because it cuts against the tidy narrative: France passed a PFAS law in February 2025 banning the substances in cosmetics, ski wax, clothing and footwear from January 2026 — and left cookware out, following a campaign by the domestic non-stick industry. The category most people associate with PFAS was the one exempted. This is contested, not settled.

The coatings that genuinely aren't PFAS — and their own catch

Sol-gel ceramic coatings, the ones usually marketed simply as "ceramic," are silica-based rather than fluorochemical. On the PFAS question they are what they say they are: no fluoropolymer, no PFAS in the coating.

The catch is a different one. It's still a coating, so it still has a service life — sol-gel surfaces are generally less abrasion- and heat-tolerant than PTFE, and food release tends to decline over months rather than years. You've solved the chemistry question and kept the durability one. That's not a reason to dismiss ceramic; if PFAS is your concern and you're content replacing pans periodically, it's a reasonable answer. It's only a problem if you were sold it as permanent.

One more thing about coated pans, worth stating without drama: PTFE begins releasing degradation products from around 260°C, with pyrolysis at roughly 400°C. Normal cooking with food in the pan rarely approaches that. An empty pan left preheating on high heat can. A handling fact, not a scare.

The materials where the question doesn't arise

Bare metals have no coating, so there is nothing fluorochemical to discuss. Stainless steel, carbon steel, cast iron and titanium are all PFAS-free by construction rather than by formulation. They each cost you something: stainless steel isn't chemically inert, and nickel and chromium do migrate into acidic food. Cast iron and carbon steel are heavy, reactive with acid, and need seasoning maintained. Titanium, the one we build with, isn't slick out of the box and marks visibly.

Our pans use Grade 1 commercially pure titanium as the food-contact surface — 0.4 to 0.6mm of solid metal clad over an aluminium core with a stainless base, so they work on every cooktop. Clad, not plated: the titanium is the surface rather than a film on top of one. There's no coating in the construction, so the PFAS question doesn't apply. Full citations are on our Evidence page.

How to check any claim in under a minute

What is the cooking surface made of? Not what it's free of. If a brand answers with a list of absences rather than a material, you haven't been told.

Is it a coating? If yes, ask what kind — PTFE, sol-gel ceramic, or something proprietary. "Proprietary" is an answer worth noting.

Does the claim cover the whole pan or just the surface? Handles, rivets, gaskets and processing aids are all places a claim can quietly narrow.

If it's metal, is it clad or plated? Ask for the thickness in millimetres. A plated film of around 0.1mm is a different product from clad construction, and a spec sheet will usually change the subject to the pattern or the total pan thickness rather than answer.

What we're not claiming

We're not claiming our cookware treats, prevents or improves any condition, and we're not claiming coated pans will harm you. Modern PTFE is stable in ordinary use and the acute-toxicity case against it is weaker than the internet suggests. Our argument is narrower: a coating is a consumable with a service life, a clad bare metal isn't, and if you've chosen a material specifically to avoid something, a coating postpones the question rather than answering it.

Titanium asks something in return. It's naturally low-stick with proper technique — preheat the empty pan, add oil, wait for it to ripple, then drop to medium-low before food goes in. Get the heat wrong and it will stick, as any bare metal will. It marks, and those marks become patina rather than damage. The Care Guide covers the routine, and the FAQ handles most of the rest.

If you're starting with one piece, the 28cm Signature Hammered Frying Pan is where we'd point you. The Complete Kitchen is the full set, and the Titanium Cutting Board extends the same non-porous surface to prep.

The short version

PFAS is a family of thousands of substances defined by a structural test, and PTFE is in it — regulators banning PFAS in cookware have said so explicitly. "PFOA-free" describes an industry baseline from 2015 and answers a different question. Sol-gel ceramic is genuinely PFAS-free but still a coating with a service life. Bare metals sidestep the issue entirely, each at its own cost.

Ask what the surface is made of. Everything else follows from that.
