Where these two actually differ
- We flag Bacterial growth in filter media, Incomplete contaminant removal claims and Pitcher housing durability and degradation on the Brita and not on the ZeroWater.
- We flag Ion-exchange resin cartridge composition opacity, Bacterial or mold growth in housing and spigot and Polypropylene plastic durability and UV exposure on the ZeroWater and not on the Brita.
- The Brita is BPA-free plastic pitcher with activated carbon filter cartridge where the ZeroWater is borosilicate glass, plastic pitcher housing, ion-exchange resin cartridge, 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 →
