Where these two actually differ

  • We flag Nonstick coating degradation and fume risk, Coating integrity loss over time and Proprietary coating composition undisclosed on the Calphalon and not on the GreenPan.
  • We flag Coating degradation and particulate release, Aluminum leaching from base metal and Thermal polymer decomposition fumes on the GreenPan and not on the Calphalon.
  • The Calphalon is Hard-anodized aluminum with proprietary nonstick coating (unspecified) where the GreenPan is ceramic nonstick coating, which is most of the difference in these two grades.
  • The gap is 55 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, which covers 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 →
