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 Berkey.
- We flag Bacterial growth if unmaintained, Housing leachables (if plastic), Filter element composition and leaching and Unverified contaminant removal claims on the Berkey and not on the Aquamira.
- 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, 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 →
