Where these two actually differ
- We flag Bacterial and microbial growth in housing and filters, Activated carbon filter degradation and dust release, RO membrane integrity failure and microbial breakthrough and Tubing and connector leakage or degradation on the Aquasure and not on the Aquasure.
- We flag Bacterial biofilm in storage tank, Carbon filter media degradation and particle shedding and Membrane rupture and unfiltered water bypass on the Aquasure and not on the Aquasure.
- The Aquasure is RO membrane, carbon filters, stainless steel housing where the Aquasure is Plastic housing, RO membrane, carbon filter media, which is most of the difference in these two grades.
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 →
