Where these two actually differ
- We flag Chemical overdose or misuse, Degradation and loss of efficacy over time, Glass bottle breakage and spillage and Chlorine residue and taste/odor on the Aquamira and not on the S'well.
- We flag Bacterial or mold growth and Cap and closure safety (choking or leaching) on the S'well and not on the Aquamira.
- The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the S'well is Double-wall 18/8 stainless steel, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
