Where these two actually differ
- We flag PTFE fume risk (thermal decomposition), Coating degradation and microparticle release, Aluminum leaching from bare substrate and Lack of use-temperature guidance on the Calphalon and not on the GreenPan.
- We flag Aluminum leaching from base material and Ceramic coating degradation and mechanical wear on the GreenPan and not on the Calphalon.
- The Calphalon is Nonstick coating (type unspecified) where the GreenPan is Ceramic nonstick coating (PTFE-free proprietary formulation), which is most of the difference in these two grades.
- The gap is 85 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
- We are less certain about the Calphalon grade, at 35% confidence against 82%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
