Where these two actually differ
- We flag Bacterial growth in pitcher housing and filter media, Resin saturation and reduced contaminant removal and Inadequate testing and disclosure of sourced filter materials on the PUR 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 PUR.
- The PUR is Activated carbon and resin filter media, plastic pitcher housing where the ZeroWater is Activated carbon and ion-exchange resin filter media, 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 →
