Where these two actually differ
- We flag PTFE thermal decomposition / fume risk, Aluminum leaching (post-coating failure), Nonstick coating degradation over time and PFAS in coating manufacturing (not product residue) on the Calphalon and not on the GreenPan.
- We flag Ceramic coating degradation over time on the GreenPan and not on the Calphalon.
- The Calphalon is Nonstick fluoropolymer (PTFE-based) coating over aluminum where the GreenPan is ceramic nonstick coating, 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.
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 →
