Overview
Where the Risk Lives
Most conversations about PFAS focus on drinking water. But product exposure accounts for a significant share of total body burden for many Americans. The difference is that you control it. Water contamination depends on where you live and what your utility does. Product exposure depends on what you buy and how you use it.
Each product category carries a risk level based on exposure pathway, frequency of contact, and available evidence. High means PFAS routinely migrate into food, skin, or air. Moderate means exposure is real but less direct. Low means PFAS may be present but contact is infrequent or absorption is limited.
Room-by-Room Action Guide
Your Home, Room by Room
Kitchen High Risk
The kitchen is the highest-risk room in the home for PFAS exposure. Non-stick cookware and food packaging are the two primary sources. A 2025 UNC Gillings School of Public Health study confirmed that cookware and food processing contribute meaningfully to overall PFAS body burden.
- Replace any pan that is scratched, chipped, or peeling. Coating fragments enter food directly.
- Switch to cast iron, stainless steel, carbon steel, or ceramic cookware verified as PFAS-free.
- Do not preheat empty non-stick pans and keep heat below 450°F. Degradation begins around 500°F and releases fluorinated gases.
- Avoid reheating food in fast food packaging or microwave popcorn bags. Transfer to glass or ceramic first.
- Use glass, stainless steel, or silicone food storage in place of plastic bags or disposable wraps.
- Ignore PFOA-free labels on cookware. Most substitute PTFE or another PFAS compound.
Bathroom High Risk
Cosmetics and personal care products are a significant and often overlooked exposure route. Foundation, mascara, eyeliner, waterproof makeup, and some moisturizers use PFAS as film-forming agents. Skin absorption through mucous membranes around the eyes and lips is direct and daily. Dental floss adds a separate oral exposure pathway.
- Replace PTFE-coated dental floss (Oral-B Glide and similar products) with plain nylon or silk floss. A 2019 study found measurably higher PFAS blood levels in women using PTFE-coated floss.
- Search your cosmetics on the EWG Skin Deep database at ewg.org/skindeep before replacing products.
- Look for PFAS-free labeling specifically. PFOA-free on cosmetics is not meaningful.
- Flag any ingredient containing “fluoro”: fluoropolymer, PTFE, polytetrafluoroethylene, perfluoro.
- Choose mineral-based or certified organic cosmetics. Look for EPA Safer Choice or GreenScreen certification.
- Avoid fabric-treated shower curtains and liners. Choose untreated options.
Living Room Moderate Risk
Stain-resistant furniture and carpets are a primary source of PFAS in indoor dust. As treated products age, PFAS migrate into household particles. Children and pets spending time on floors are exposed through dust ingestion and skin contact. This is one of the most common residential PFAS pathways not related to water.
- Vacuum frequently with a HEPA-filter vacuum. This is the single most effective ongoing action for reducing household dust exposure.
- Decline stain protection treatments at the point of sale on furniture, carpets, and rugs. These are almost always PFAS-based.
- Choose natural fiber carpets and rugs without stain treatment: wool, cotton, or jute.
- Wipe hard surfaces regularly with a damp cloth to reduce surface dust accumulation.
- Leave shoes at the door. Shoes track in PFAS-contaminated soil and dust.
Bedroom and Nursery High Risk for Children
Children face higher risk from product exposure because they have more hand-to-mouth contact with PFAS-containing surfaces and ingest more dust relative to body weight. Stain-resistant treatments on sleep products, car seat covers, and bibs result in prolonged direct skin contact during some of the most critical developmental windows.
- Choose untreated natural fiber mattress covers and sleep products. Stain-resistant treatments on children’s sleep items mean prolonged skin contact overnight.
- Wash new clothing and soft goods before first use to reduce surface chemical transfer.
- Avoid stain-treated bibs, changing pads, and play mats. Choose untreated cotton or silicone alternatives.
- Keep floors clean with frequent HEPA vacuuming. Babies and toddlers ingest dust at far higher rates than adults.
- Look for PFAS-free certification on mattress covers and waterproof pads, not just PFOA-free labeling.
Laundry and Outdoor Gear Moderate Risk
Waterproof and water-resistant clothing uses durable water repellent (DWR) finishes that have historically contained PFAS. Traditional long-chain C8 DWR has been replaced with short-chain C6 alternatives, which are still PFAS. Skin contact and washing both release PFAS from treated fabrics, with microfibers shedding into wastewater.
- When replacing rain gear or outdoor clothing, look specifically for PFAS-free DWR labeling. Gore-Tex PFAS-free, Keen footwear, Fjallraven, and REI-supplied gear from Fall 2024 onward are verified options.
- Do not treat clothing with spray-on DWR products unless labeled PFAS-free. Most spray-on waterproofing still contains PFAS.
- Existing outdoor gear with PFAS-based DWR does not require immediate replacement. Skin absorption from intact fabric is lower risk. Replace as products wear out.
- Use PFAS-free detergent. Some laundry products have historically contained PFAS-based stain treatment agents.
- Wash outdoor gear less frequently and on cold to reduce microfiber shedding.
Certifications
How Reliable Are the Claims?
The term PFAS-free is not federally regulated. Manufacturers use it without independent verification. These certifications are more reliable because they require third-party testing or review.
Certification or
Claim
Reliability
What It Means
EPA Safer Choice
High
PFAS cannot be intentionally added to Safer Choice certified products. Third-party reviewed. Strong standard for cleaning and some personal care products.
Green
-Screen Certified
High
Rigorous hazard assessment of all ingredients. Products must meet benchmark scores. Covers cookware, textiles, and building materials.
Cradle to
Cradle Certified
High
Full material health assessment required. PFAS disqualify products from higher certification levels.
PFAS-Free
(unverified claim)
Low
No federal standard or verification requirement. Manufacturer self-declaration only. Does not guarantee testing was conducted.
PFOA-Free
Low
Means PFOA was not intentionally added. Product may still contain PTFE, GenX, or other PFAS. Common on non-stick cookware.
PTFE-Free
Moderate
Confirms no PTFE. Stronger than PFOA-free for cookware. Does not guarantee freedom from all other PFAS.
bluesign
Moderate
Textile and apparel standard covering chemical inputs. Restricts many PFAS but verify specifically per product.
OEKO-TEX
Standard 100
Moderate
Tests finished textiles for harmful substances including some PFAS. Does not cover all PFAS compounds.
