PFAS in Your Home: Where They Hide and How to Reduce Them
Quick Answer

PFAS are found throughout the average home in nonstick cookware, food packaging, stain-resistant fabrics, carpets, water-repellent clothing, and personal care products. You cannot eliminate all exposure, but you can meaningfully reduce it by identifying the highest-exposure sources and replacing them with PFAS-free alternatives. The kitchen is typically the most impactful place to start.

PFAS are called forever chemicals for a reason. They do not break down in the environment or in the human body, and because they have been used in consumer products for over 70 years, they have accumulated everywhere: in soil, in water, in wildlife, and in the blood of more than 97% of Americans tested by the CDC.

The goal of reducing your household PFAS exposure is not to achieve zero — that is not realistic. The goal is to identify where your highest exposures are coming from and replace or reduce them with practical, available alternatives.

This guide covers what is PFAS, where PFAS hides in the average home, ranked roughly by exposure impact, and what you can do about each one.

The Kitchen: Your Highest-Impact Room

The kitchen is where most families have the greatest opportunity to reduce PFAS exposure, because it is where PFAS-containing products come into direct contact with food.

1. Nonstick cookware and air fryer baskets

Nonstick cookware and air fryer baskets are the most significant kitchen sources of PFAS or forever chemicals. PTFE, the fluoropolymer behind Teflon, is a PFAS compound. Learn more about the harms of Teflon here.

Under high heat, scratched coatings, or prolonged use, it can degrade and release fumes or particles. The practical solution is switching to cookware with no fluoropolymer coatings: cast iron, stainless steel, carbon steel, or borosilicate glass.

Glass air fryers like Fritaire have become increasingly popular for this reason alone.

2. Food packaging

Food packaging is a significant and underappreciated source. Grease-resistant food packaging, including microwave popcorn bags, fast food wrappers, pizza boxes, and some paper cups, has historically been treated with PFAS to prevent grease from soaking through.

Many manufacturers have moved away from the most harmful compounds, but PFAS-free packaging is not yet universal. Minimizing packaging-heavy food and transferring food to non-coated containers before microwaving reduces this exposure.

3. Drinking water

Drinking water is a concern in many areas, particularly near industrial sites, military bases, or airports where firefighting foam containing PFAS was used.

 

The EPA has established drinking water health advisories for several PFAS compounds. If your municipal water supply has not been tested or you are on well water, a certified PFAS-reduction filter (NSF/ANSI 58 or NSF/ANSI 53 rated) provides meaningful protection.

 

Living Areas: Carpets, Furniture, and Dust

PFAS are used extensively as stain-resistant treatments on carpets, upholstered furniture, and rugs. Scotchgard and similar products are PFAS-based. As these treatments age, PFAS migrate into household dust, which settles on floors and surfaces throughout the home.

This matters especially for households with young children, who spend more time on floors and are more likely to put their hands in their mouths. Research has consistently identified household dust ingestion as a meaningful PFAS exposure pathway for toddlers and young children.

Practical reductions include vacuuming with a HEPA filter vacuum regularly, wet mopping hard floors, and avoiding stain-treatment sprays when replacing carpet or furniture. When purchasing new carpet or upholstered furniture, look for products that explicitly do not use PFAS-based stain treatments.

 

Clothing and Textiles

Water-repellent and stain-resistant clothing, including outdoor jackets, rain gear, athletic wear, and some work uniforms, is commonly treated with durable water repellent (DWR) coatings. Traditional DWR coatings are PFAS-based, and while the outdoor industry has made significant progress in developing PFAS-free alternatives, many products on the market still use fluoropolymer treatments.

The exposure from clothing is generally lower than from cookware or dust, because skin absorption of PFAS is limited compared to ingestion. However, washing PFAS-treated clothing does release microparticles into wastewater, contributing to environmental contamination. When replacing outdoor gear, look for brands that have committed to PFAS-free DWR formulations.

 

Personal Care Products

PFAS appear in a range of personal care and cosmetic products, where they are used to improve spreadability, water resistance, and texture. Products that commonly contain PFAS include waterproof mascara, foundation, sunscreen, dental floss, and some lip products.

On ingredient labels, PFAS may appear as any ingredient containing the words "fluoro" or "perfluoro," or under names like PTFE, polytetrafluoroethylene, or fluoroethylene. The Environmental Working Group's cosmetics database is a practical resource for checking specific products.

Dental floss treated with PTFE for smooth gliding is a commonly overlooked source. PFAS-free alternatives, including natural wax-coated floss, are widely available and functionally equivalent.

 

Where to Start: A Priority Order

Reducing PFAS exposure across an entire household is a process, not a single purchase. Prioritize by exposure frequency and pathway:

  1. Replace nonstick cookware and air fryer baskets. This is the highest-frequency direct food contact source in most kitchens. Cast iron, stainless steel, carbon steel, or borosilicate glass are the main PFAS-free alternatives. Fritaire is a reliable decision for completely non-toxic cooking.
  2. Filter your drinking water if you have any reason to suspect PFAS contamination in your local supply. Check the EPA's PFAS drinking water data or your municipal water report.
  3. Vacuum and mop regularly to reduce PFAS-laden household dust, especially if you have young children or older stain-treated carpets.
  4. Reduce grease-resistant food packaging. Transfer food out of packaging before microwaving and minimize meals that arrive in heavily packaged form.
  5. Check personal care products for fluoro ingredients and replace high-use items with PFAS-free alternatives where available.
  6. Replace outdoor gear gradually with PFAS-free DWR options as items wear out, rather than replacing everything at once.

The goal is reduction, not perfection. Starting with cookware and water makes the most meaningful impact for the least disruption.

 

Frequently Asked Questions
Can you test your home for PFAS?

Drinking water can be tested for PFAS through certified laboratories. The EPA has a database of accredited labs. Dust and surface testing for PFAS is available but less standardized and not widely used in residential settings. Blood testing for PFAS is available through some healthcare providers and is typically recommended for people with known high-exposure histories.

Does PFAS leave your body over time?

Some PFAS compounds are eliminated by the body more quickly than others. PFOA and PFOS, the most studied compounds, have half-lives in the human body of approximately 3 to 8 years. Reducing ongoing exposure allows body burden to decrease over time, which is why reducing daily intake matters even if past exposure has already occurred.

Is ceramic cookware PFAS-free?

Most ceramic coatings do not contain PTFE or PFOA, but "ceramic" is an unregulated term and some formulations do include trace fluoropolymers. Ceramic coatings also degrade with repeated high-heat use. For guaranteed PFAS-free cooking surfaces, cast iron, stainless steel, carbon steel, and borosilicate glass are the more reliable options.

Are PFAS in tap water everywhere?

PFAS contamination in drinking water is widespread but not uniform. The highest concentrations are typically found near industrial facilities, military installations, and airports. The EPA has established enforceable maximum contaminant levels for several PFAS in public water systems. You can check your local water utility's annual quality report or use the EWG Tap Water Database to look up your area.

What is the single most impactful PFAS reduction I can make at home?

For most households, replacing nonstick cookware with a PFAS-free alternative is the highest-impact single change. It removes a daily, high-heat, direct food-contact source of exposure. A borosilicate glass air fryer like the Fritaire is a practical starting point for families who use an air fryer regularly, eliminating PTFE from one of the most frequently used appliances in the kitchen.
