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 PUR.
- We flag Bacterial biofilm growth in cartridge, Activated carbon dust release, Ion-exchange resin exhaustion and bypass and Housing seal degradation from mineral buildup on the PUR and not on the Aquamira.
- The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the PUR is activated carbon and ion-exchange resin cartridge; plastic housing, which is most of the difference in these two grades.
- These two are 5 points apart, 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 →
