Where these two actually differ
- We flag Biofilm and bacterial growth (maintenance-dependent), Degradation due to heat or chemical exposure, Allergic sensitization to silicone or additives and Loss of seal or structural integrity over time on the Diva Cup and not on the Diva Cup.
- We flag Silicone degradation or leaching from improper cleaning agents, Bacterial or fungal colonization from inadequate cleaning or storage and Vaginal irritation or allergic response to silicone on the Diva Cup and not on the Diva Cup.
- The Diva Cup is Medical-grade silicone (body); no reported coatings or treatments where the Diva Cup is medical-grade silicone, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Diva Cup is the one to buy.
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 →
