PFAS-Free Pads: Safer Non-Toxic Period Products
Looking for PFAS-free pads? Testing found forever chemicals in many period products. Here is what the research shows and the safest organic cotton options.
PFAS-Free Pads: Safer Non-Toxic Period Products
Period products touch some of the most absorbent, sensitive skin on the body, for days at a time, month after month, for decades. So when testing started finding forever chemicals in pads and liners, it landed as one of the more personal PFAS stories out there. The reassuring part: clean options exist, they work beautifully, and switching is simple. Here is what the research actually found and how to choose PFAS-free pads with confidence.

The short answer
Independent testing has found PFAS markers in a meaningful share of pads, liners, and other period products. The chemicals are usually not added on purpose, but they show up often enough to take seriously given how and where these products are used. The safest choice is a pad with a certified organic cotton cover and no added fragrance, chlorine bleaching, or unnecessary synthetic layers. Those are widely available and just as effective.
What the testing found
This concern is backed by real lab work. A series of analyses commissioned by Mamavation and Environmental Health News between 2020 and 2022 found that 48 percent of sanitary pads, incontinence pads, and panty liners tested contained PFAS, along with 22 percent of tampons and 65 percent of period underwear. Separately, researchers led by Notre Dame professor Graham Peaslee detected low levels of fluorine in about half of more than 100 period products tested, presenting the findings at a 2023 American Chemical Society meeting.
To be fair and precise: detecting fluorine markers indicates PFAS is likely present, and the levels found were often low. But “often, at low levels, against very absorbent skin, for years” is exactly the profile that makes a simple swap worthwhile.
Why PFAS would be in a pad at all
Here is the why. In period products, PFAS can be used to help the material wick and stay dry, and in the case of period underwear, to add stain resistance. The chemicals can also slip in through manufacturing and supply-chain contamination rather than as an intentional ingredient. Either way, the result is the same for a shopper: you cannot tell from the package, so the move is to choose materials that have nothing to hide. I cover more in my guide to PFAS-free menstrual products and the PFAS Free Life database.
How to choose PFAS-free pads
Clean period products are easy to spot once you know the labels. Look for a certified organic cotton top sheet and core, since organic cotton pads without synthetic additives, fragrance, or chlorine bleach are considered the least toxic disposable option. Choose fragrance-free, because added scent is an undisclosed mix. Favor brands that publish PFAS or organic-fluorine testing. And if you want to go further, reusable organic cotton cloth pads or a menstrual cup remove disposables from the equation entirely.

Frequently Asked Questions
Do menstrual pads contain PFAS? Independent testing found PFAS markers in roughly 48 percent of pads, liners, and incontinence products in one series of analyses. The chemicals are usually not added intentionally, but they appear often enough to choose carefully. Certified organic cotton pads are the safest option.
Why would a pad have PFAS? PFAS can help period products wick moisture and stay dry, and add stain resistance in period underwear. It can also enter through manufacturing or supply-chain contamination rather than as a listed ingredient.
What are the safest pads to use? Pads with a certified organic cotton cover and core, no added fragrance, and no chlorine bleaching are considered the least toxic disposable option. Reusable cloth pads and menstrual cups avoid disposables entirely.
Is organic cotton automatically PFAS-free? Organic cotton avoids many synthetic additives, which lowers risk, but certification plus a brand’s own PFAS testing is the strongest assurance. Look for both when you can.
