Where these two actually differ
- We flag Plastic reservoir leachables (oligomers, residual monomers), Bacterial growth in filter media and tubing, Inadequate PFAS removal (false sense of security) and Mold or mildew in housing seams and spigot 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 activated carbon filter media, plastic reservoir housing 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 →
