Where these two actually differ
- We flag Azo dyes and synthetic dyes and Allergic contact dermatitis from dyes or finishes on the Aisle and not on the Lunapads.
- We flag Microplastic shedding from water-resistant barrier on the Lunapads and not on the Aisle.
- The Aisle is Organic cotton, wood pulp fiber where the Lunapads is organic cotton blend, water-resistant gusset, 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 →
