Where these two actually differ
- We flag Undisclosed waterproof coating composition and Coating degradation and microleaching over time on the Arctic Zone and not on the Zojirushi.
- We flag Seal and gasket degradation on the Zojirushi and not on the Arctic Zone.
- The Arctic Zone is Stainless steel exterior with waterproof internal coating (unspecified) where the Zojirushi is Stainless steel body, no nonstick or special coating mentioned, 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 Zojirushi is the one to buy.
- We are less certain about the Arctic Zone grade, at 35% confidence against 88%, 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 →
