Where these two actually differ
- We flag Bacterial/microbial growth in filter if unmaintained, Filter cartridge quality and filter media purity and Housing gasket/seal degradation on the Soma 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 Soma.
- The Soma is BPA-free plastic pitcher, carbon/ion-exchange filter cartridge 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 →
