PFAS in Stainless Steel Cookware: Which Brands Grade Best and Worst

When you're shopping for stainless steel cookware, PFAS (per- and polyfluoroalkyl substances) contamination is rarely on your radar—but it should be. These "forever chemicals" migrate from nonstick coatings into food and can accumulate in your body over time. Based on available materials and data, OXO OXO Agility Tri-Ply Stainless Steel 13 Piece Kitchen Cookware Pots and Pans Set emerges as our top-graded performer, earning a B grade (80/100 safety score) in our model-based estimate from materials and public disclosure.

The gap between best and worst performers in this category is stark. While OXO and select GreenPan lines demonstrate higher concern mitigation through ceramic nonstick approaches and transparent materials claims, major brands like All-Clad, Circulon, and Calphalon score F grades (15–35/100) due to limited PFAS disclosure and reliance on traditional fluoropolymer coatings. This guide cuts through marketing claims to show which cookware genuinely presents lower concern for PFAS exposure.

Product	Grade	Safety Score	Verdict
OXO Agility Tri-Ply	B	80/100	Lower concern; ceramic nonstick coating
GreenPan Apex Hybrid	B	80/100	Lower concern; ceramic hybrid construction
GreenPan Treviso	B	80/100	Lower concern; fully stainless, no ceramic coating
GreenPan Prism	F	60/100	Moderate concern; hybrid coating formulation
Farberware Classic Traditions	F	55/100	Moderate concern; ceramic coating, limited disclosure
All-Clad Tri-Ply	F	35/100	Higher concern; fluoropolymer nonstick, minimal PFAS info
Cuisinart Professional	F	35/100	Higher concern; no ceramic alternative; opaque materials
Calphalon Classic	F	35/100	Higher concern; traditional nonstick, sparse disclosures
Circulon Symmetry	F	5/100	Highest concern; hard-anodized with nonstick; no PFAS detail
Our Place Titanium Pro	F	15/100	Higher concern; premium pricing does not offset opaque coating chemistry

The Best Performer: OXO Agility Tri-Ply (Grade B, 80/100)

OXO's Agility line stands out because it combines three critical factors: a ceramic nonstick coating (rather than traditional fluoropolymer), transparent materials labeling, and a brand commitment to PFAS-free formulations. The tri-ply stainless steel construction ensures even heat distribution across the entire cookware set, and the ceramic coating is not associated with PFAS compounds based on available materials and data.

Materials & Build: The Agility set features a stainless steel 18/10 core with aluminum middle layer and magnetic stainless steel base. The nonstick surface is ceramic-based, not PTFE or GenX. OXO explicitly states no PFAS in marketing materials, though note that brand-stated claims should be distinguished from third-party lab verification—we have not located an independent test report for this specific product line.

Pros: Ceramic nonstick coating reduces PFAS-concern pathways; induction-compatible; dishwasher-safe; competitively priced (~$120–180 for a 13-piece set); OXO's materials transparency is industry-leading in this category.

Cons: Ceramic coating may show wear after heavy use (chipping possible); not as nonstick-durable as older PTFE formulas; limited long-term durability data on ceramic alternative coatings.

Runner-Up: GreenPan Apex Hybrid & Treviso (Grade B, 80/100)

GreenPan's B-graded lines—particularly the Apex Hybrid and Treviso—represent the second-best option. Apex uses a hybrid stainless steel and ceramic nonstick design, while Treviso opts for pure stainless steel without any nonstick coating.

Materials & Build (Apex): Tri-ply construction (stainless/aluminum/stainless) with proprietary ceramic hybrid nonstick. GreenPan markets this as "thermolon" technology and claims no PTFE, PFOA, or PFAS. Our research found no third-party lab test published by GreenPan, but the brand's consistent messaging across product lines suggests established materials governance.

Materials & Build (Treviso): Full stainless steel (18/10 grade) with no nonstick coating whatsoever—eliminating the nonstick-chemical pathway entirely. This is the simplest, lowest-PFAS-concern option if you accept that stainless requires more oil and skill to prevent sticking.

Pros (Apex): Hybrid ceramic nonstick avoids fluoropolymer; oven-safe to 400°F; GreenPan's sustainability claims and brand positioning around chemical avoidance. Pros (Treviso): Zero nonstick coating = zero coating-based PFAS risk; excellent heat retention; durable for decades.

Cons (Apex): Nonstick coating durability concerns (similar to OXO); less affordable than pure stainless (~$180–220). Cons (Treviso): Requires more cooking skill and oil; heavier; not ideal for users accustomed to modern nonstick convenience.

The Lower-Performers: GreenPan's F-Graded Lines

Not all GreenPan cookware is created equal. Four of its product lines earned F grades (60/100 safety score): the Prism, Valencia Pro, Balance, and Nova Gallery sets. All use ceramic or hybrid coatings, but public materials disclosure is more opaque—some product pages lack detailed composition information, and GreenPan's broader portfolio inconsistency raises questions about manufacturing controls.

Why They Grade Lower: Incomplete ingredient lists; lack of third-party certification or testing; inconsistent brand messaging across SKUs. A consumer cannot reliably determine which specific chemicals are in the Prism's nonstick layer from publicly available sources.

The Worst Performers: All-Clad, Circulon, Calphalon, Cuisinart, Our Place

These premium and mid-market brands received F grades (5–35/100) due to reliance on traditional fluoropolymer-based nonstick systems and minimal PFAS-related disclosure. This is not an accusation—it reflects the fact that these brands have not publicly committed to PFAS reduction and do not provide transparent coating chemistry.

All-Clad Tri-Ply (Grade F, 35/100): All-Clad's classic tri-ply set uses a proprietary nonstick that All-Clad does not break down publicly. The brand touts durability and performance but offers no PFAS-related statements or certifications. At $400+, premium pricing does not correlate with chemical transparency.

Circulon Symmetry (Grade F, 5/100): Circulon's hard-anodized line scored the lowest in our analysis. Hard-anodized surfaces are often paired with PTFE-based nonstick layers, and Circulon provides no public information about PFAS content or alternative coating research. The 5/100 score reflects the combination of traditional chemistry and information vacuum.

Calphalon Classic (Grade F, 35/100): Calphalon's entry-level stainless set uses conventional nonstick without ceramic or PFAS-avoidance claims. No published materials analysis available.

Cuisinart Professional & Radiant Pro (Grade F, 35/100): Cuisinart's professional lines similarly rely on traditional nonstick formulations with no PFAS transparency initiatives. The brand does not distinguish itself in chemical safety.

Our Place Titanium Pro (Grade F, 15/100): Our Place's direct-to-consumer premium cookware carries premium pricing (~$200–300) but offers opaque information on nonstick composition. The "Titanium Pro" branding suggests durability, not PFAS avoidance. No third-party testing or ceramic alternatives published.

What to Avoid

• Vague "Nonstick" Labels Without Coating Details: If a brand says "nonstick" but won't specify PTFE, ceramic, or mineral-based, assume traditional fluoropolymer. This is especially true for brands like Circulon and legacy Calphalon lines.
• PFOA-Free Claims Without PFAS Statements: PFOA is only one PFAS compound. A brand can claim "PFOA-free" while using GenX or other newer PFAS chemicals. Demand full PFAS avoidance statements or ceramic/stainless alternatives.
• Hard-Anodized Without Coating Transparency: Hard anodization strengthens aluminum but is often paired with PTFE nonstick. Circulon Symmetry exemplifies this opacity.
• Premium Pricing as a Proxy for Safety: Our Place and All-Clad command high prices but do not translate cost into PFAS-risk mitigation. Expensive cookware can still use traditional fluoropolymer coatings.

Our Pick: OXO Agility Tri-Ply (Best Overall), with GreenPan Treviso (Best for Purists)

For most households, OXO Agility offers the best balance of PFAS-concern reduction, practical usability, and affordability. The ceramic nonstick coating is not associated with PFAS based on available materials and data, and OXO's public materials statements are transparent relative to competitors. You will sacrifice some nonstick durability compared to older PTFE formulas, but this is an acceptable trade-off for lower PFAS exposure risk.

If you are willing to abandon nonstick convenience entirely, GreenPan Treviso eliminates the nonstick pathway and provides durable, lifetime cookware—a cleaner choice for PFAS-conscious households that can master traditional stainless steel technique.

Important Legal Note: These grades represent our model-based estimate from materials and public disclosure, not laboratory testing. No association of ceramic nonstick coatings with PFAS contamination has been documented in reviewed sources, but absence of evidence is not evidence of absence. If you require absolute certainty, request third-party test results directly from manufacturers or contact an independent lab. PFAS exposure from cookware is one pathway among many (food packaging, drinking water, textiles, etc.); see our cookware finder for a complete product inventory.

Frequently Asked Questions

1. Can I use PTFE-coated cookware safely if I cook at low temperatures?

PTFE coatings typically begin degrading around 400–500°F, releasing fluorinated compounds that may include PFAS. While low-temperature cooking reduces that risk, it does not eliminate migration of PFAS into food, particularly if the coating is scratched or aged. Ceramics avoid this pathway entirely
