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 Naya.
  • We flag Rubber/silicone seal degradation and Bacterial or mold growth in double-wall cavity on the Naya and not on the Aquamira.
  • The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Naya is Stainless steel double-wall construction, 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: 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 →
