The Short Answer
Reusable cloth pads are safe, but their safety depends entirely on how they are manufactured and how you wash them. When properly sanitized, they are actually cleaner and more breathable than traditional disposable pads.
However, a July 2025 study from the University of Notre Dame found that nearly 30% of reusable menstrual products contain PFAS (toxic "forever chemicals"). Before you make the swap, you must verify the brand is PFAS-free and commit to a rigorous washing routine.
Why This Matters
Disposable pads are packed with plastics, synthetic fragrances, and questionable adhesives. Switching to cloth pads seems like an obvious upgrade for your body and the environment. Are Pads Safe
But reusable pads introduce two unique risks: microbial buildup and chemical waterproofing. If you don't wash them correctly, blood-soaked fabric becomes a breeding ground for yeast and bacteria. Are Reusable Panty Liners Sanitary
Furthermore, to make cloth pads leak-proof, some manufacturers rely on toxic chemicals. Dermal absorption of PFAS in the highly permeable vaginal area is a serious concern, as these chemicals are linked to hormone disruption and cancer. Is There Pfas In Period Underwear
What's Actually In Reusable Pads
- Organic Cotton or Bamboo ā The absorbent core and top layer. These are highly breathable and safe, provided they are certified organic. Are Organic Pads Worth It
- TPU or PUL (Polyurethane Laminate) ā The waterproof backing. This is a medical-grade, inert plastic that physically blocks leaks without the need for harmful chemicals. Is Plastic In Pads Bad
- PFAS (Per- and Polyfluoroalkyl Substances) ā The invisible threat. Nearly a third of reusable period products use these toxic chemicals as a cheap liquid-repellent coating. Which Period Underwear Has Pfas
- Silver Nanoparticles ā Sometimes added as an antimicrobial treatment. While it fights odor, it can disrupt your natural vaginal microbiome. Is Silver In Period Underwear Safe
What to Look For
Green Flags:
- Oeko-Tex or GOTS Certification ā Proves the fabric is free from harmful chemicals and agricultural pesticides.
- PFAS-Free Guarantee ā Look for brands that explicitly state their waterproof layers are tested and made without forever chemicals.
- Un-dyed Top Layers ā Natural, unbleached cotton against the skin prevents dye-related contact dermatitis.
Red Flags:
- "Stain-Resistant" Claims ā If the fabric magically repels stains, it is likely treated with toxic PFAS.
- Generic Cheap Brands ā Bargain brands on Amazon often use unregulated materials and undisclosed chemical treatments to cut costs.
- "Odor-Eliminating" Tech ā Often code for harsh antimicrobial treatments that can cause vulvar irritation.
The Best Options
If you want to try reusable pads, you have to buy from transparent brands that publicly share their safety testing.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| Rael | Organic Cotton Reusable Pads | ā | GOTS-certified organic cotton and strictly PFAS-free. |
| Cora | Reusable Period Pad | ā | Clean materials and highly absorbent without toxic coatings. |
| Generic Brands | Cheap Multipacks | š« | High risk of undisclosed PFAS waterproofing and poor materials. |
The Bottom Line
1. Demand PFAS-free materials. Only buy reusable pads from brands that explicitly test for and ban forever chemicals from their production lines.
2. Wash with hot water and strong detergent. A March 2025 study showed that washing cloth pads with just water leaves massive bacterial loads, but using detergent and ironing the pads completely eliminates the microbes.
3. Dry them thoroughly. Damp pads breed yeast and bacteria. Ensure they are 100% bone-dry before storing them away. Can Wipes Cause Yeast Infections
FAQ
Are reusable pads more hygienic than disposable pads?
Yes, if you wash them correctly. Cloth pads made of natural fibers allow your skin to breathe, which reduces the trapped moisture that causes rashes and odors in plastic disposable pads. Pads Vs Period Underwear
How do you sanitize reusable pads to prevent infection?
Detergent, heat, and complete drying are mandatory. Rinse them in cold water first to prevent blood stains, then wash them with a strong, unscented detergent. A 2025 study found that ironing cloth pads after washing is the single most effective way to kill lingering bacteria.
Can reusable pads cause Toxic Shock Syndrome (TSS)?
The risk of TSS from external pads is virtually zero. TSS is primarily associated with internal products like high-absorbency tampons or cups left in too long. However, wearing a dirty cloth pad can still cause a local bacterial or yeast infection, so proper hygiene is non-negotiable. Is Tss Still A Concern
