Where these two actually differ
- We flag Coating degradation and integrity loss, Aluminum leaching and Microparticle shedding from coating on the GreenPan and not on the Wonderchef.
- We flag Undisclosed coating polymer (possible PTFE/fluorinated compounds), Coating degradation and microparticle release and Thermal fume risk from undisclosed binders or slip agents on the Wonderchef and not on the GreenPan.
- The gap is 75 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
- We are less certain about the Wonderchef grade, at 35% confidence against 100%, 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 →
