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 Aqua Guard and not on the Aqua Guard.
- The Aqua Guard is Stainless steel housing, copper components, RO membrane, UV filtration where the Aqua Guard is RO membrane, carbon filters, stainless steel housing, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the Aqua Guard is the one to buy.
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 →
