Where these two actually differ
- We flag PTFE fume risk (thermal decomposition), Coating degradation and particulate release and Volatile organic compounds (VOCs) and off-gassing on the GreenPan and not on the GreenPan.
- We flag Ceramic coating degradation over time on the GreenPan and not on the GreenPan.
- The GreenPan is Nonstick ceramic-based coating (GreenPan proprietary, unspecified) where the GreenPan is ceramic nonstick coating, which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
- We are less certain about the GreenPan grade, at 45% confidence against 78%, 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 →
