Where these two actually differ
- We flag Bacterial growth in filter media or housing, Carbon dust or resin particle release into water and Degradation and bypass of contaminants over time on the Aqua Fresh and not on the Aqua Fresh.
- We flag Bacterial growth in saturated filter media, Carbon dust inhalation during installation and Inadequate contaminant removal if filter is counterfeit or defective on the Aqua Fresh and not on the Aqua Fresh.
- The Aqua Fresh is activated carbon and/or ion-exchange resin filtration media where the Aqua Fresh is activated carbon and ion-exchange resin (standard RO/carbon filter media), which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric, which covers 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 →
