PFAS in Measuring Cups: Safe Kitchen Measuring Tools

Forever chemicals are the nickname for per- and polyfluoroalkyl substances (PFAS), and they’re showing up in places most families never thought to look. PFAS in measuring cups is real, and the small daily exposures really do add up. Here’s what to look for and what to swap.

Why PFAS in measuring cups matters

PFAS has been linked to hormone disruption, high cholesterol, immune problems, and cancer risk. Studies have found detectable PFAS in the blood of people with everyday household exposures. Since these chemicals don’t break down in the body, every exposure you can avoid matters, especially if you have kids or you’re pregnant.

Finding PFAS-free measuring cups

Labels won’t always tell you what you need to know. Manufacturers don’t have to disclose PFAS use on most consumer products in the U.S. Here’s what actually works:

• Look for certifications: OEKO-TEX Standard 100, bluesign, and GOTS all prohibit PFAS
• Skip these marketing terms: “Water-resistant,” “stain-resistant,” “wrinkle-free,” or “grease-proof” usually mean PFAS coatings
• Ask the brand: Email and ask directly if they use fluorinated treatments. Good companies answer this clearly
• Check the PFAS Free Life Database: We test products and list the ones that are actually safe

Safe Measuring Cups Plastic Recommendations

When switching away from PFAS-containing products, look for:

• Stainless steel or glass options — both are inert and PFAS-free by nature
• OEKO-TEX certified textiles — tested and free from harmful chemicals including PFAS
• Brands with published chemical policies — Patagonia, Cotopaxi, and others publish their commitments openly
• Certified organic options where relevant, which typically exclude synthetic treatments

One trusted product to consider: Pyrex Simply Store 18-Piece Glass Food Storage Set, which offers a PFAS-free alternative you can order today.

Additional Tips to Reduce Your measuring cups plastic PFAS Exposure

Beyond the products themselves, daily habits matter:

• Ventilate your home — PFAS can off-gas and settle into household dust, which is a significant exposure route for young children
• Wash new measuring items before first use — this can reduce surface chemical loads
• Choose food-grade materials for anything that contacts food or skin directly
• Filter your drinking water — a reverse osmosis system is the most effective household option for PFAS removal

Frequently Asked Questions

How do I know if my measuring has PFAS?

Without laboratory testing, it can be difficult to know for certain. Watch for marketing terms like ‘water-repellent,’ ‘stain-guard,’ ‘grease-resistant,’ or ‘wrinkle-free’ which often signal PFAS treatments. Look for certifications like OEKO-TEX Standard 100 or bluesign that prohibit PFAS. You can also search the PFAS Free Life Database at database.pfasfreelife.com for verified clean products.

Are PFAS-free measuring 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.

What health risks are linked to PFAS in measuring?

PFAS exposure from consumer products has been associated with several health concerns, including elevated cholesterol, immune system disruption, hormone interference, and in some cases increased cancer risk. Children and pregnant women are considered especially vulnerable. The good news is that reducing exposure through product swaps can lower your body burden over time, as PFAS do eventually clear from the body when exposure stops.
