Where these two actually differ
- We flag Residual manufacturing compounds / silicone impurities and Mold or bacterial colonization from improper storage on the Flex and not on the Saalt.
- We flag Bacterial and fungal growth and Allergic reaction to silicone on the Saalt and not on the Flex.
- The Flex is Medical-grade silicone, no added fluoropolymers where the Saalt is Medical-grade silicone, 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: 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 →
