Air Flow Underpads, Package vs Incontinence Pads: which is safer?

Where these two actually differ

• We flag PFAS in waterproof backing (graded separately, noted here for context), Polymer leaching from backing layer during use and Skin irritation or sensitization from coating degradation on the Tena and not on the Eco By Naty.
• We flag Heavy metals in cellulose or plant-derived materials on the Eco By Naty and not on the Tena.
• The Tena is Cellulose core with waterproof backing layer (unspecified polymer) where the Eco By Naty is Bamboo-derived viscose, cotton, plant-based absorbent core, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Eco By Naty is the one to buy.
• We are less certain about the Tena grade, at 35% confidence against 78%, because it discloses less.
