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 and biofilm growth in storage tank and membrane housing and Water stagnation if tank remains pressurized between uses on the Aquasure and not on the Aquasure.
- The Aquasure is RO membrane, carbon filters, stainless steel housing where the Aquasure is Reverse osmosis membrane and carbon filters, 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 →
