Where these two actually differ
- We flag Bacterial growth in filter media and stagnant water, Seal degradation and cross-contamination, Filter media saturation and reduced contaminant removal and Activated carbon dust or filter particle shedding on the Aqua Crest 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 Aqua Crest.
- The Aqua Crest is Plastic pitcher (BPA-free typically marketed), activated carbon filter media 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 →
