A consumer guide to forever chemicals in everyday items

PFAS in products appear far more widely than most people realize. These chemicals show up in cookware, food packaging, clothing, carpets, personal care products, and dozens of other items found in ordinary households. Manufacturers have used PFAS for decades because they resist heat, water, grease, and stains. That utility came with a cost that researchers are still measuring.

The problem is not just exposure from a single product. It is cumulative. PFAS build up in the body over time, and most people encounter them through multiple sources every day. Children face higher risk because they are still developing and tend to have more direct contact with treated surfaces and packaging.

This guide covers 15 major product categories where PFAS are commonly found, explains the specific chemicals involved, rates the exposure risk, and identifies safer alternatives for each one.

Most state laws and the FDA phase-out target PFAS deliberately used as a functional ingredient — such as a non-stick coating or stain repellent. This does not cover PFAS that appear as trace contaminants from manufacturing. Some products without intentionally added PFAS may still test positive due to contaminated raw materials or equipment.

Non-stick cookware is the most widely recognized source of PFAS in the home. The coating is typically polytetrafluoroethylene (PTFE), the same chemical as Teflon. PTFE itself is considered relatively stable at normal cooking temperatures. The risk increases significantly above 500°F, when the coating begins to degrade and release fluorinated gases. Scratched or worn non-stick pans present a more direct risk — coating fragments can flake directly into food.

• Replace pans that are scratched, chipping, or discolored.
• Cook on low to medium heat and never pre-heat an empty non-stick pan.
• Avoid PFOA-free claims as a safety signal. PFOA-free cookware typically uses replacement PFAS compounds.
• Choose cast iron, stainless steel, or ceramic cookware verified as PFAS-free.
• State bans: Minnesota banned PFAS in cookware as of January 1, 2025. Maine, Colorado, Connecticut, and Illinois have bans effective 2026–2028.

Grease-proof food packaging was one of the largest sources of dietary PFAS exposure in the United States. In February 2024, the FDA confirmed that U.S. manufacturers had stopped selling PFAS-based grease-proofing agents for paper and paperboard food packaging. This voluntary phase-out removed a major source of dietary PFAS. However, it does not cover imported packaging, plastic containers, or non-paper materials. Studies show that people who frequently eat microwave popcorn have measurably elevated PFAS blood levels.

• Transfer food out of packaging before microwaving whenever possible.
• Avoid microwave popcorn bags and make stovetop popcorn instead.
• At least 15 states have enacted enforceable bans on PFAS in food packaging covering most direct-contact paper and plant-fiber products.

PFAS appear in cosmetics as film-forming agents, texture enhancers, and water resistance additives. Long-wear foundations, waterproof mascara, lip gloss, setting sprays, and some moisturizers all use PFAS to improve durability. The exposure route is primarily dermal absorption, particularly through mucous membranes around the lips and eyes. Washington State banned PFAS-containing cosmetics as of January 1, 2025. Illinois and Connecticut have bans effective 2026 and 2027.

• Search your products on the EWG Skin Deep Cosmetics Database at ewg.org/skindeep.
• Look for products specifically labeled PFAS-free — not just PFOA-free.
• Ingredients to flag:anything with “fluoro” in the name — fluoropolymer, PTFE, polytetrafluoroethylene, perfluoro.

Durable water repellent (DWR) finishes on rain jackets, ski gear, and activewear historically used long-chain PFAS. The industry shifted to short-chain PFAS after PFOA and PFOS were phased out, but short-chain compounds carry their own persistence concerns. Exposure occurs through skin contact during use and through microfibers shed during washing.

• Look for PFC-free or PFAS-free DWR certification from bluesign, OEKO-TEX, or manufacturers using Nikwax, Grangers, or similar fluorine-free treatments.
• Wash outdoor gear less frequently and with PFAS-free detergent to reduce microfiber shedding.
• Brands phasing out PFAS DWR include Patagonia, REI (since Fall 2024), and Arc’teryx.

A 2019 study found that women who used Oral-B Glide dental floss had higher blood levels of PFHxS compared to women who did not. Glide floss is coated with PTFE to create the smooth sliding texture. Exposure occurs through absorption through gum tissue. Minnesota banned PFAS in dental floss as of January 1, 2025. Maine and Colorado follow in 2026.

• Switch to uncoated nylon floss, silk floss, or a water flosser.
• Avoid any floss that lists PTFE or polytetrafluoroethylene on the packaging.
• The floss swap is one of the easiest and lowest-cost PFAS reductions available.

Look for products that say PFAS-free with a third-party certification. A manufacturer’s own claim without verification carries less weight. Use the PFAS Central product list at pfascentral.org or EWG’s databases to cross-check claims.

These resources help identify verified PFAS-free products across major categories. All link to independent certification or database sources.
