In 2020 the Ecology Center tested the coatings on 14 nonstick cooking pans and 10 nonstick baking pans, across a range of brands and prices. Eleven of the 14 cooking pans, 79 percent, were coated with PTFE. Two of the 10 baking pans were. The rest wore some other coating, and not all of those were an improvement.
PTFE is polytetrafluoroethylene. Teflon is a brand name for it. It is a fluoropolymer, which is a plastic, and the Ecology Center calls it the polymer form of PFAS. That is the plain description of the slick layer on most nonstick pans, and it almost never appears on the box.
The scare that ended, and the one that did not
Most people who remember a nonstick controversy remember PFOA. PFOA is a fluorochemical that was used as a processing aid when PTFE was made. It was never the coating itself.
In 2006 the EPA asked eight companies in the industry, DuPont and 3M’s Dyneon among them, to cut PFOA from their emissions and products by 95 percent by 2010 and to work toward eliminating it by 2015. The EPA reports that every participating company says it met the goals, and that domestic production and import of PFOA has been phased out by those companies. The same page notes that companies outside the program may still make and use it.
So “PFOA free” on a label is a real improvement and a narrow one. It says one processing chemical was left out. It says nothing about what the pan’s surface is made of. The surface is still PTFE.
What happens when the pan gets hot
The old worry about nonstick pans was never the egg. It was the empty pan on a hot burner.
In 2003 the Environmental Working Group petitioned the Consumer Product Safety Commission for warning labels on PTFE products that get hot. Science News reported that the group’s own tests found an empty nonstick pan on a home stovetop reached 400°F in 2 minutes and 730°F in 5 minutes. The same report says fumes from overheated PTFE can kill birds, and that people breathing them can develop flulike “polymer-fume fever.” The group also said factory workers handling hot PTFE were required to wear respirators wherever it reached 400°F.
The maker’s side of that story matters. A spokesperson for the company that sells Teflon maintained that even at 500°F, PTFE-coated cookware will not release material harmful to human health. That is two parties disagreeing about a test from 2003, and this article will not settle it. What you can take from both: nobody disputes that an empty pan heats fast, and nobody recommends leaving one on the burner.
The substitutes are not a clean escape
The Ecology Center’s report is useful for what it found beyond PTFE. Packaging claims, it says, can lead buyers to purchase a PTFE pan when they think they are buying an alternative. And among the pans without PTFE, the testers found undisclosed BPA-based coatings on one cooking pan and two baking pans.
That is the pattern worth watching in this category. A “ceramic” label, a “non-toxic” label, a “PFOA free” label: each names something absent or something that sounds benign, and each leaves the actual surface unstated. The Ecology Center identified the coatings themselves, not just the claims, which is how it could catch the mismatch.
Its testing covered only the type of coating on each pan. It did not test for PFOA, GenX or other PFAS used in manufacturing and possibly left in the finished pan, so the report cannot tell you what a given pan carries beyond its surface.
What a plastic-free kitchen asks of a pan
If you want no plastic touching your food, a PTFE pan is out. It does not matter whether it is PFOA free, how new it is, or how carefully you use it. The surface is a fluoropolymer.
What remains are the pans people cooked in for centuries: cast iron, carbon steel, stainless steel, enameled iron where the enamel is glass fused to metal. All of them ask for something the nonstick pan was sold to spare you. You preheat, you use fat, you learn when the pan is ready, and you scrub. Eggs will stick the first few times. That is the price of a surface with no coating to flake, scratch or fume.
I think that trade is a good one, and I also think it is a real trade. A buyer who wants a pan that behaves like a nonstick should look on the product page for the name of the actual material. If the page says “nonstick” and never says PTFE, or says “ceramic” and never says what that is, the page has not answered the question. Ask the maker. A company with a straight answer will give it in a sentence.
How Amaterio sorts products on this question is laid out on the standard page. There is no cookware category here yet, and until one has been checked product by product, no pan gets a verdict from us.
