You see "PFAS-free" plastered on cookware boxes now. You also see "PFOA-free." And "non-toxic." And "Teflon-free." These do not all mean the same thing, and the gap between what they sound like and what they actually mean is where shoppers get confused.
This is the plain-English version of what the chemistry actually is, what was banned and what was not, and what label to actually look for.
PFAS is the family. PTFE and PFOA are members.
PFAS stands for per- and polyfluoroalkyl substances. The EPA defines them as a class of thousands of synthetic chemicals built around carbon-fluorine bonds — one of the strongest bonds in chemistry. That strength is why PFAS are useful (they repel water, oil, and stain) and why they are a problem (they do not break down in the environment, which is why the press calls them "forever chemicals").
PFAS are in:
- Non-stick cookware coatings
- Food packaging (grease-resistant wrappers)
- Stain-resistant carpet and upholstery
- Waterproof textiles (rain jackets, hiking gear)
- Firefighting foam
- Cosmetics (some)
The two PFAS members you have heard of are PTFE and PFOA.
PTFE (polytetrafluoroethylene) is the fluoropolymer. It is the slick coating that makes a Teflon pan non-stick. It is itself a PFAS — a long-chain fluorinated polymer. When people say "Teflon" they almost always mean PTFE.
PFOA (perfluorooctanoic acid) was historically used as a processing aid in the manufacture of PTFE. It was the chemical that environmental groups raised the alarm on in the early 2000s — the one linked to contamination around DuPont plants.
This distinction matters: PFOA was a manufacturing input, PTFE is the actual coating. They are not the same chemical.
What was banned and what was not
Here is the timeline most cookware shoppers do not know:
- 2006: EPA convenes the PFOA Stewardship Program. Eight major chemistry companies — including DuPont and 3M — voluntarily commit to eliminate PFOA from manufacturing.
- 2015: The phaseout deadline is met. PFOA is no longer used in US non-stick manufacturing.
- 2024: The EPA finalizes the first national drinking water standards for six PFAS compounds.
So if you read "PFOA-free" on a Teflon-style pan today, that label is technically true and also extremely misleading. Every non-stick pan made in the US since 2015 is PFOA-free. The word "PFOA-free" tells you nothing about whether the pan still uses PTFE — and most of them do.
PTFE itself was never banned. The replacement processing aid for PTFE manufacture is now typically a chemistry called GenX (HFPO-DA), which is itself a PFAS and which the EPA is currently regulating under the same drinking water rule.
What "PFAS-free" actually means on a label
When a brand labels cookware "PFAS-free," they are claiming the coating contains zero PFAS. That rules out PTFE coatings entirely. The legitimate PFAS-free options are:
Ceramic-coated. A mineral-based sol-gel coating sprayed onto an aluminum or stainless body. The two best-known brands in this category are Caraway and Our Place's Always Pan 2.0. Both publish third-party testing showing zero PFAS, lead, cadmium, and mercury. Coating life is the trade-off: 2-3 years of regular use is a fair expectation.
Cast iron. Just iron and seasoning oil. Lodge-style pre-seasoned cast iron has zero coating chemistry to worry about. Heavy, slow to heat, lasts a lifetime.
Carbon steel. Same family as cast iron, lighter and thinner, used widely in restaurant kitchens. Develops a natural non-stick patina with use. Same chemistry profile as cast iron — no synthetic coating.
Stainless steel. A solid metal alloy with no coating at all. The non-stick learning curve is real (preheat the pan, add oil, wait for the shimmer) but the pan itself never wears out.
What to actually look for when replacing a pan
The shortest version: look for the words "PFAS-free" or "no PTFE" on the box, not "PFOA-free."
If the box says "PFOA-free" but does not mention PTFE or PFAS, assume it is a PTFE pan. That is not necessarily a disaster — modern PTFE manufacturing has cleaned up substantially since the 2010s phaseout — but it is also not what most people are picturing when they go shopping for "non-toxic" cookware.
