PFAS Free Maternity Clothes: Safe Options During Pregnancy

When you’re pregnant, you think about what you eat, what you drink, what products you put on your skin. But most people don’t think about what their leggings are made of. Stretchy maternity clothing often gets treated with PFAS-based coatings to make it water-resistant or stain-repellent, and those chemicals sit against your skin all day long.

Why this matters more during pregnancy

A 2022 study in Environmental Research found detectable PFAS in blood samples of people with ordinary household exposures. PFAS can interfere with hormones, raise cholesterol, and suppress the immune system. Pregnant women and developing babies are especially sensitive to these effects, which is why cutting exposure where you can makes a real difference.

How to spot PFAS-free maternity clothing

Manufacturers aren’t required to disclose PFAS treatments on clothing labels in most U.S. states, so reading the tag won’t always tell you much. What actually works: look for certifications like OEKO-TEX Standard 100, bluesign, or GOTS, all of which ban PFAS in certified products. Watch out for terms like “water-resistant,” “stain-resistant,” or “wrinkle-free” on tags or product listings, because those usually mean a fluorine-based treatment was applied. When in doubt, email the brand and ask directly whether their fabrics use fluorinated coatings. You’d be surprised how many will answer. The PFAS Free Life Database also lists tested, verified products across hundreds of categories.

Maternity clothing we’d actually recommend

For leggings, the Motherhood Maternity Women’s Essential Stretch Cotton Leggings are a solid pick. They’re cotton-based with a secret fit belly panel, they have over 17,000 reviews, and you can find them for around $21. They’re one of the most popular maternity leggings on Amazon for a reason.

Beyond leggings, look for maternity clothes in untreated organic cotton, bamboo, or merino wool. Brands that publish their chemical policies (rather than just saying “eco-friendly” somewhere on the website) are the ones worth trusting. OEKO-TEX certification is the quickest filter for online shopping.

Other ways to lower PFAS exposure during pregnancy

Your clothes are one piece of it. A few other things that help:

• Wash new maternity items before wearing them. It won’t remove all chemical residues, but it does reduce surface levels.
• Open windows regularly. PFAS can settle into household dust, and babies and toddlers are especially exposed because they’re on the floor.
• Use glass or stainless steel for food and drinks instead of coated plastic.
• If you haven’t already, look into a water filter. A reverse osmosis system is the most effective household option for removing PFAS from your tap water.

Frequently Asked Questions

Can I test my home for PFAS contamination?

Yes. You can test your drinking water for PFAS using certified laboratory testing services or at-home kits from companies like SimpleLab. For other types of exposure, from products or household dust, testing is more complex, but starting with your water is the most impactful first step. Your state health department may also offer resources or low-cost testing programs.

Do all maternity products contain PFAS?

No, not all maternity products contain PFAS. However, many products that are marketed as water-resistant, stain-resistant, or non-stick have historically used PFAS-based treatments. The safest approach is to look for third-party certifications like OEKO-TEX Standard 100 or to contact the manufacturer directly to ask about their chemical policy.

Are PFAS-free maternity alternatives effective?

Yes, PFAS-free alternatives have improved significantly in recent years. Natural materials like stainless steel, cast iron, glass, and untreated natural fibers perform well without any chemical coatings. For water-resistant textiles, fluorine-free DWR treatments have become widely available and work well for everyday conditions. Many families find the alternatives work just as well once they make the switch.
