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 KOR.
  • We flag Bacterial growth in filter cartridge, Filter cartridge plastic component leaching and Microplastics from cartridge degradation on the KOR and not on the Aquamira.
  • The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the KOR is Stainless steel body, activated carbon filter cartridge, 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 →
