Where these two actually differ
- We flag Microplastic shedding from synthetic fibers on the Lunapads and not on the Ruby Love.
- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Lunapads.
- The Lunapads is organic cotton, nylon, gusset absorbent layer where the Ruby Love is organic cotton, waterproof backing layer, 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 Ruby Love 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 →
