What Are PFAS Free Products?

PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used in thousands of consumer products to resist water, grease, and stains. They do not break down naturally in the environment or in the human body, earning them the nickname "forever chemicals." PFAS free products are designed without intentional addition of these chemicals, though not all such products have been independently tested for PFAS contamination. Understanding what PFAS free products are, which brands genuinely offer them, and what the actual health concerns are requires looking beyond marketing claims to the evidence available.

What Is the PFAS Problem?

PFAS have been detected in the drinking water, blood serum, and soil of millions of people across the United States and globally. Based on available materials and data, scientific associations have reported links between exposure to certain PFAS compounds and health effects including liver damage, thyroid disease, and developmental concerns. It is important to note that association is not the same as causation, and individual risk depends on exposure levels and duration.

The chemicals were introduced in the 1940s to provide stain resistance, water repellency, and non-stick properties. They are commonly found in cookware, food packaging, textiles, cosmetics, dental floss, and water-resistant clothing. Because PFAS persist indefinitely in the environment, reducing new exposure through product choices is one way consumers can lower their potential intake.

Which Common Products Contain PFAS?

High-Concern Product Categories

The following product types historically contain or may contain PFAS, based on their intended function:

• Non-stick cookware: Traditional PTFE-based non-stick pans (such as some versions of Teflon) contain or are manufactured with PFOA, a PFAS compound
• Food packaging: Grease-resistant paper boxes, fast-food containers, and some microwave popcorn bags have been found to contain PFAS
• Water-resistant textiles: Rain jackets, outdoor activewear, and waterproof boots often use PFAS-based coatings for durability
• Cosmetics and personal care: Waterproof mascara, foundation, and some sunscreens may contain fluorinated compounds
• Menstrual products: Some tampons and period pads have been tested and found to contain PFAS in their synthetic materials or fluid-blocking layers
• Stain-resistant fabrics: Carpet, upholstery, and treated bed sheets commonly use scotchgard or similar PFAS finishes
• Dental floss: PTFE-based floss, the most common type, inherently contains fluorinated compounds

What Does "PFAS Free" Actually Mean?

Brand Claims vs. Third-Party Verification

When a brand states a product is "PFAS free," this claim rests on one of three levels of support:

1. Brand statement without testing: The manufacturer says they do not intentionally add PFAS but has not conducted independent lab testing
2. Brand testing in-house: The company has tested the product but not through a third-party, peer-reviewed lab
3. Third-party lab verification: An independent, accredited laboratory has tested the final product and found no evidence of PFAS above a stated detection limit

For this article, "lower concern" products are those where the manufacturer has disclosed their materials or where third-party reviewers have found no evidence of PFAS in tested samples. Our model-based safety estimates are not lab certainty but reflect the transparency and material sourcing practices available for public review.

PFAS Free Product Examples by Category

Cookware and Bakeware

Ceramic and glass cookware offer non-stick properties without relying on PFAS chemistry. The Caraway Ceramic Saute Pan and Lid features a ceramic coating derived from sand, representing a lower-concern alternative to traditional non-stick. Similarly, the Caraway Ceramic Baking Sheet and Caraway 15-inch Ceramic Nonstick Pizza Pan use the same ceramic formula. All three products hold a grade of A (100/100 safety) in our model-based estimate from materials and public disclosure.

Food Storage

Glass and plant-based polymer containers avoid the PFAS-containing coatings sometimes used in plastic storage. The Airtight Caraway Food Storage Set combines glass vessels with silicone gaskets and stainless steel lids, earning a grade A (100/100 safety). For reusable food storage films, Stasher Storage Bags are made from food-grade silicone and carry the same grade A rating based on materials disclosed.

Water Filtration

While water filters do not remove all PFAS, several models are built with materials chosen to avoid introducing PFAS during filtration. The TAPP Water Faucet Filter (Rapid Flow, 400 gal) holds NSF certification and is rated grade A. For under-sink systems, the PureLiving Puri 7 Reverse Osmosis System is also grade A. Pitcher filters from Honeywell and replacement cartridges from Clearly Filtered provide lower-concern alternatives, both rated grade A. Visit our water filters category page for a complete comparison.

Menstrual Products

Organic cotton and non-synthetic period care products represent lower-concern options. Cora Organic Tampons with Applicator and Natracare Super Tampons with Applicator are both rated grade A. For reusable alternatives, Knix Teen Super Leakproof Reusable Snap Pads combine organic cotton with polyurethane backing rather than PFAS-based water-resistant layers, also grade A. Ruby Love Women's Hipster Period Underwear is similarly rated. See our period care category for more options.

Textiles and Apparel

Natural fiber clothing, untreated wool, and waxed cotton avoid PFAS water-resistant coatings. The Organic Basics Kariban Bio Apron is constructed from organic cotton and rates grade A. Treated bed linens, such as the Boll and Branch Signature Hemmed Sheet Set, use alternative stain-resistant finishing processes and are rated grade A based on materials disclosed.

Specialty Products

Fabric and spot protectors formulated without PFAS are available: Folex Spot Remover and Carbona are both rated grade A. For winter sports, Purl Natural Ski Wax and Purl Eco Ski and Snowboard Wax use plant-based waxes instead of PFAS-based water repellents, both grade A. In cosmetics, RMS Beauty Organic Makeup is formulated without fluorinated compounds and rates grade A.

How to Identify PFAS Free Products When Shopping

What to Look For on Labels

Manufacturers who avoid PFAS often label products with these phrases: "PFAS free," "fluorine-free water repellent," "ceramic non-stick," "PFA-free," or "without fluoropolymers." However, not all unlabeled products contain PFAS, and not all labeled claims have been independently verified. Review our methodology page to understand how we evaluate claims versus evidence.

Red Flags and Unclear Claims

Be cautious of vague statements such as "eco-friendly non-stick" or "advanced protection" without specification of the chemistry used. Traditional non-stick cookware, scotchgard-treated fabrics, and conventional dental floss contain PFAS unless explicitly labeled otherwise. Ask manufacturers directly for test reports or material declarations if product descriptions are unclear.

The Honest Risk Level: What Science Shows

Most Americans have detectable PFAS in their blood from decades of environmental and product exposure. The EPA and CDC monitor PFAS levels in drinking water and blood plasma. According to available materials and data, associations have been reported between elevated PFAS exposure and outcomes including altered liver enzymes, elevated cholesterol, and immune suppression, particularly in children. However, individual risk from switching to PFAS free products is difficult to quantify without knowing a person's total exposure from all sources (food, water, air, dust).

Switching to lower-concern products is a reasonable precaution, especially for items in direct contact with food or worn against the skin. It is not necessary to replace all consumer goods at once, but prioritizing frequently used items, children's products, and items that contact food or water is a practical approach.

Bottom Line

PFAS free products are manufactured without intentional addition of these persistent chemicals, though not all have been independently lab-tested. Brands including Caraway, Stasher, Cora, Boll and Branch, and Organic Basics offer lower-concern alternatives across cookware, storage, menstrual care, and textiles, rated grade A in our model-based safety estimates. Distinguish brand-stated claims from third-party verified ones by requesting test reports or consulting our product finder. Reducing exposure through informed product choices is one of few ways consumers can limit PFAS intake, alongside choosing filtered water and avoiding treated textiles where practical.

Frequently Asked Questions

Are PFAS free products actually PFAS free?

Products labeled "PFAS free" by the manufacturer have not intentionally included PFAS in their recipe or intended chemistry. However, unless independently tested, there is no guarantee of zero parts per trillion. Our grades reflect the transparency of material sourcing and brand disclosure, not lab-verified absence. Many products rated grade A in our model have disclosed materials that do not include intentional PFAS, based on available materials and data, but some have not been tested by a third-party lab.

How much does switching to PFAS free products cost?

Ceramic cookware and glass storage are often comparable in price to traditional non-stick alternatives, ranging from $30 to $200 per item. Organic cotton menstrual products cost slightly more than conventional brands: expect 20 to 40 percent higher prices. Water filters vary widely from $20 for pitcher cartridges to over $500 for reverse osmosis systems, but per-liter costs are generally lower than bottled water. Starting with one or two high-use items is an affordable way to begin reducing PFAS.

What if I cannot afford to replace all my household products right now?

Prioritize items that touch food or water frequently, such as cookware and food storage. Second, replace products worn against skin daily, including clothing, undergarments, and period care. Third, consider high-use textiles like bed sheets and towels. Food packaging and cosmetics are harder to avoid but represent one-time exposures rather than repeated contact, so they rank lower in immediate priority. Gradual replacement over one to two years allows for budgeting without financial strain.
