GreenPan Lima 12.5" Ceramic Non-Stick Open Wok with Helper Handle
Lower concern; ceramic non-stick is a plausible PFAS-avoidant choice, but unverified coating composition.
GreenPan Lima uses a ceramic-based non-stick coating claimed to be Teflon-type coating and PFOA-free, positioning it as a PFAS-safer cookware option. The brand explicitly markets PFAS-free construction, though the proprietary coating formula lacks independent third-party verification.
Brand says: “GreenPan cookware is PTFE/PFOA-free and uses plant-derived non-stick coatings.”

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
GreenPan Lima uses a proprietary ceramic non-stick coating formulated without Teflon-type coating (Teflon) or PFOA, reducing thermal decomposition hazards that plague conventional non-stick cookware above 500°F. The wok body is likely hard-anodized or stainless aluminum with a ceramic topcoat. Ceramic non-stick coatings are mineral-based polymer hybrids designed to shed fewer volatile compounds at normal cooking temperatures compared to Teflon-family coating, though the exact resin binder in GreenPan's proprietary blend is not fully disclosed publicly.
The brand's record and disclosure
GreenPan is owned by The Cookware Company and has marketed itself as a PFAS-free alternative since its founding. The brand has not faced major safety recalls related to coating degradation or leaching as of public record. However, GreenPan does not publish third-party lab certifications or detailed safety data sheets for its ceramic coating chemistry; the 'proprietary blend' claim is marketing language that obscures whether other synthetic polymers or adhesion promoters might pose minor risks. Industry reputation suggests the brand's PFAS-free positioning is genuine, but independent verification of all coating constituents is absent.
How it compares in its category
This wok sits in the mid-tier ceramic non-stick segment, competing with brands like Our Place and Caraway. It avoids the known Teflon-type coating fume risk of legacy non-stick woks and the aluminum leaching potential of bare anodized surfaces. Ceramic coatings are more prone to chipping and gradual performance loss than Teflon-type coating but do not release hazardous off-gases if the coating degrades. The helper handle is a practical design choice for safe handling of a 12.5-inch wok, reducing burn or strain risk.
If you buy it
Hand-wash only; dishwasher detergent and abrasion accelerate ceramic coating wear. Avoid high heat (keep burner below medium-high; coating integrity begins degrading above 400-500°F sustained use). Do not use metal utensils; silicon or wood only. Expect coating to gradually lose non-stick performance over 2-3 years of regular use; replace when food regularly sticks or residual discoloration appears. Store with a soft cloth between nesting surfaces to minimize scratching.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Ceramic coating degradation and microflaking
Ceramic non-stick coatings are inherently more fragile than Teflon-type coating and can shed small ceramic particles into food if chipped or abraded. No specific recalls for GreenPan Lima are on record, but wear is normal; inspect regularly and discard if visible flaking appears.
Aluminum leaching from substrate (if not adequately sealed)
Hard-anodized aluminum wok body is standard and the ceramic topcoat should prevent direct aluminum contact with acidic foods. GreenPan does not disclose anodization thickness or barrier testing; theoretical risk is low if coating remains intact, but damage exposes the substrate.
Proprietary resin binder toxicity (unverified composition)
The ceramic coating binder is not publicly disclosed. Unlikely to include Teflon-type coating or BPA based on brand claims, but water-borne epoxy, polyester, or vinyl ester resins are common in ceramic cookware coatings and residual monomers or solvents are not independently verified as absent.
Teflon-type coating fume risk (thermal decomposition)
By design, this product eliminates Teflon-type coating; fume risk from this coating is not a concern. No thermal hazard specific to ceramic non-stick reported for GreenPan products.
Handle material and durability
Helper handle material is not specified in public product data; if plastic, check that it does not soften or off-gas near the wok rim during use. No complaints or recalls on record for GreenPan Lima handle failure or chemical leaching.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
Formulations and coatings change between production runs. Always check the current label before buying.
