Where these two actually differ
- We flag Bacterial growth in filter media and housing, Carbon dust or resin particles in filtered water, Contaminant rebound after saturation and Inadequate removal of modern contaminants on the Brita and not on the ZeroWater.
- We flag Bacterial growth in reservoir if filter unmaintained or water stored too long, Filter cartridge degradation and particle escape if overfilled or misseated and Ion-exchange resin saturation without visible warning on the ZeroWater and not on the Brita.
- These two are level, close enough that price and fit should decide it rather than our grade.
- We are less certain about the ZeroWater grade, at 72% confidence against 100%, because it discloses less.
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 →
