PFAS in Cookware: Brand Comparison & State Ban Map (2026 Update)

Your Pan Says PFOA-Free — That Doesn't Mean What You Think

Walk through any kitchenware aisle and you'll see "PFOA-free" stamped on box after box. It sounds reassuring. But here's what that label actually tells you: the pan doesn't contain one specific chemical. It says nothing about the thousands of other forever chemicals in the PFAS family.

PFAS (per- and polyfluoroalkyl substances) is a broad class of man-made compounds that do not break down in the environment or the human body. PTFE, the coating most people know as Teflon, is itself a type of PFAS. A pan can be truthfully labeled "PFOA-free" and still contain PFAS, because its PTFE coating is a forever chemical by definition.

Why does this matter? PFOA, the processing aid historically used to manufacture PTFE, was classified by the International Agency for Research on Cancer (IARC) in December 2023 as a Group 1 carcinogen, the same tier as tobacco and asbestos. PFOA was phased out of US production in 2015, yet PTFE itself remains in widespread use.

This is not a fringe concern. A nationally representative Consumer Reports survey of 2,158 adults in April 2025 found that 65% of US adults are at least somewhat concerned about PFAS, PTFE, or PFOA in their nonstick cookware. A 2025 study in the Journal of Environmental Research linked higher blood levels of PFOA and PFHpA to a significantly increased risk of fatty liver disease in adolescents. This is a family health issue, not just a label debate.

What Happens to PTFE Coatings Over Time

PTFE coatings don't last forever, even though the chemicals in them do. When heated above roughly 500°F (260°C), PTFE begins to degrade and release fumes. Most home stovetops can exceed that temperature within minutes of preheating an empty pan.

The physical wear is equally concerning. Research has shown that a single broken patch in a PTFE coating can release up to 2.3 million microplastic and nanoplastic particles. Even small scratches, the kind caused by a metal spatula or an enthusiastic scrub, can shed thousands of particles within 30 seconds of cooking. This is not a hypothetical risk. It's what happens every time you use a scratched PTFE pan.

Testing by the Ecology Center found that 79% of nonstick cooking pans tested positive for PTFE coatings, frequently without any disclosure on the product label. A 2025 Consumer Reports investigation discovered that a pan marketed as "PFOA-free" actually tested positive for PFOA contamination.

Brand claims alone are not enough. Third-party testing and genuine material transparency are becoming the new trust standard in cookware, and for good reason.

The US State PFAS Cookware Ban Map (2025–2028)

State legislatures aren't waiting for federal action. Here's where PFAS cookware restrictions stand right now:

• Minnesota: Became the first state to ban PFAS-containing nonstick cookware, effective January 1, 2025.
• Colorado, Maine, Vermont: Similar bans took effect January 1, 2026.
• Illinois: Enacted a broad ban on PFAS in cookware, effective 2026.
• New Jersey: The Protecting Against Forever Chemicals Act was signed January 12, 2026, prohibiting intentionally added PFAS in cookware.
• Connecticut: Warning labels required from July 1, 2026, with a full sales ban starting January 1, 2028.
• Kansas: HB 2674 proposes a ban on PFAS cookware sales beginning 2027 (pending).
• California: Governor Newsom vetoed SB 682 in October 2025, which would have phased out PFAS in cookware by 2031. Disclosure requirements remain in place under existing law.

The pace is accelerating. Nearly 350 PFAS bills were introduced across 39 states in 2025 alone, and 23 states are carrying active legislation into 2026, the fastest wave of state-level PFAS regulation on record.

Major retailers are moving even faster than legislators. REI required all cookware vendors to be PFAS-free as of fall 2024. Target set a goal to remove intentionally added PFAS from its own-brand cookware by 2025, and Walmart has launched broader phase-out programs.

The practical takeaway: PTFE-based cookware, including brands like Scanpan, falls under these bans. PFAS-free ceramic options are the compliant choice in regulated states.

Which Brands Use PTFE — And Which Don't

Not every brand is transparent about what's actually in its coating. Here's what we know about four of the most commonly compared nonstick cookware brands:

Scanpan uses PTFE-based nonstick technology. The brand positions itself as PFOA-free, which is accurate. But the functional nonstick layer is PTFE, placing it squarely within the PFAS family. This distinction is rarely made clear in Scanpan's own marketing.

HexClad faced a $2.5 million class-action settlement (Cliburn v. HexClad Cookware, LLC, final court approval February 2026) after marketing its cookware as "PFAS-free" while the coating contained PTFE. HexClad has since transitioned to a proprietary ceramic called TerraBond™, which it claims is PTFE-free and PFAS-free. The full composition remains proprietary, however, and independent third-party testing results have not been fully published.

Caraway uses a mineral-based ceramic coating free of PTFE, PFOA, PFAS, lead, and cadmium. Caraway has made its third-party toxicity testing publicly available, a transparency advantage noted by multiple independent reviewers.

Swiss Diamond ceramic lines (CXD and CHD) do not rely on PTFE in the coating system. The diamond-reinforced coating is PFOA-free and manufactured entirely in Switzerland using hydroelectric power, with all R&D conducted in-house since 1974.

The market is reflecting this shift. The PFAS-free ceramic cookware segment is growing at a 7.4% CAGR, nearly twice the rate of the broader nonstick market. Consumer demand is clearly heading in one direction.

Side-by-Side Comparison: Swiss Diamond vs. Scanpan vs. HexClad vs. Caraway

A few things stand out. Swiss Diamond is the only brand in this comparison that combines a verified PFAS-free ceramic coating, diamond-reinforced durability, Swiss manufacturing transparency, and a 365-day no-questions-asked return guarantee.

That last point matters because one of the most common objections to ceramic cookware is longevity. Standard ceramic coatings can wear faster than PTFE, especially under high heat or with metal utensils. Swiss Diamond's diamond-crystal reinforcement was specifically engineered to address this problem. Customers regularly report 20-plus years of use, a track record that earned the brand its #1 nonstick cookware ranking from a leading US consumer rating organization and a Gold Medal at the 1999 International Exhibition of Inventors.

Caraway deserves credit for its transparency and accessible pricing. But its 1-year warranty and standard ceramic coating leave a durability gap that becomes more noticeable over years of daily use.

How to Choose PFAS-Free Cookware That Actually Lasts

Before you buy your next nonstick pan, ask three questions:

1. Is the coating PTFE-free, not just PFOA-free? As covered above, PFOA-free is not the same thing. Ask specifically about PTFE.
2. Has the brand published independent third-party lab results? If the answer is "proprietary" or "trust us," keep looking.
3. Is the cookware compliant with your state's current or upcoming PFAS ban? If you live in Minnesota, Colorado, Maine, Vermont, Illinois, New Jersey, or Connecticut, this is already a practical consideration.

On durability: look for reinforced ceramic coatings rather than standard ceramic-only options. Diamond-crystal technology, the approach Swiss Diamond uses, is specifically designed to extend the life of ceramic nonstick surfaces under real kitchen conditions, including high heat and everyday wear.

PFAS-free ceramic cookware does command higher average selling prices, typically 12–18% above conventional nonstick. Think of it as a long-term investment in both health and durability, not a trend premium. And if you're uncertain about committing, Swiss Diamond's 365-day no-questions-asked return guarantee removes the risk entirely. You can cook with it for nearly a year and return it if you're not satisfied.

Here's the market signal worth noting: 74% of specialty kitchenware retailers surveyed in late 2025 had already reduced PTFE cookware shelf space by more than 20%. The category is shifting. Buying PFAS-free now puts you ahead of the curve, not behind it.

The Bottom Line on PFAS in Your Kitchen

The terminology matters. PFAS is the family of thousands of forever chemicals. PTFE is a specific PFAS used in most traditional nonstick coatings. PFOA is a now-banned processing chemical. "PFOA-free" on a label is not a guarantee that your pan is free of forever chemicals.

If you're in Minnesota, Colorado, Maine, Vermont, Illinois, New Jersey, or Connecticut, PTFE cookware is already restricted or banned. More states are following.

Among the major brands: Scanpan remains PTFE-based. HexClad's new TerraBond™ coating lacks full independent verification. Caraway offers genuine transparency at an accessible price. Swiss Diamond combines PFAS-free ceramic with diamond-reinforced durability, Swiss manufacturing heritage dating to 1974, and a return guarantee that backs every claim with a full year of risk-free use.

The cookware industry is moving toward safer materials. Choosing a verified PFAS-free pan today is both a health decision and a future-proof investment in your kitchen.
