Where these two actually differ
- We flag Bacterial growth in filter and standing water, Filter media degradation and particle shedding and Inadequate contaminant removal for specific threats on the Aquaphor and not on the Soma.
- We flag Bacterial growth in filter housing, Activated carbon dust in water and Rubber seal degradation on the Soma and not on the Aquaphor.
- The Aquaphor is Plastic pitcher with carbon/ion-exchange filter cartridge where the Soma is borosilicate glass pitcher, activated carbon filter 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 →
