Where these two actually differ
- We flag Waterproof coating composition (PFAS or alternative) and Coating degradation and particulate shedding 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 with thermal insulation and unspecified waterproof/moisture-resistant coating 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 45% 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 →
