Where these two actually differ

  • We flag Gasket and seal integrity on the Ello and not on the Klean Kanteen.
  • We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Ello.
  • The Ello is Stainless steel, bare uncoated where the Klean Kanteen is Stainless steel body, silicone gasket lid seal, which is most of the difference in these two grades.

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 →
