What you’ll learn in 4 minutes
  • The framework: why "PFOA-free" is not the same as "PFAS-free"
  • The checklist: 5 points to assess your own milk frother
  • Safe materials: which materials are proven PFAS-free
  • Next step: comparison of popular models

You’re wondering: does that whole PFAS story also apply to my milk frother? Short answer: probably. But instead of making you worry, I’ll simply give you the tools below to figure it out yourself in 60 seconds. The same ones I used when I looked into it for my own kitchen.

PFOA-free ≠ PFAS-free

Brands put "PFOA-free" on the packaging as if that means it’s safe. That’s not true. Here are the three terms side by side:

PFOA: one specific PFAS substance. Banned in the EU since 2020.

PTFE: the coating itself. Better known as Teflon. Contains PFAS substances.

PFAS: the umbrella group of 10,000+ chemical substances. PFOA is one of them.

Claim on the packaging What it means Safe?
"PFOA-free" Contains no PFOA, but can still contain PTFE and other PFAS substances. The coating is still there. No
"PTFE-free" Contains no Teflon coating. But it may contain another coating, such as ceramic with PFAS processing aids. Partly
"PFAS-free" Contains no substances from the PFAS group. No coating, or a coating that is demonstrably PFAS-free. Yes
"No coating" Material is pure glass, stainless steel, or a combination of both. No non-stick coating present. Yes
The marketing trick

“PFOA-free” is the most commonly used claim in the cookware industry. It only says that one banned substance isn’t in it. The coating—and the thousands of other PFAS chemicals—could still be in there. Compare it to a cigarette that advertises “lead-free”. Technically true, but you’re still smoking.

Assess your milk frother in 60 seconds

Grab your milk frother. Seriously—walk over to the kitchen for a second; this works best with the thing in your hands. Go through these 5 points:

  1. Look inside the jug Is it a smooth, dark layer (black, gray, dark gray)? Then it’s almost certainly a coating. Transparent glass or silver-colored steel = no coating.
  2. Check for wear Scratches, light spots, thin patches? The coating has already shed particles. Into your milk.
  3. Read the product specifications Look for “non-stick coating”, “non-stick”, or “PTFE”. If any of those terms appear, your milk frother contains a coating.
  4. Check the claim: PFOA-free or PFAS-free? “PFOA-free” isn’t enough (see the framework above). Only “PFAS-free” or “no coating” gives certainty.
  5. How old is your milk frother? The longer you use it, the more the coating wears down. After 1 to 2 years of daily use, wear is visible on most models.
Quick conclusion

Does your milk frother score 2 points or more? Then you’re probably taking in coating particles every day through your coffee. No reason to panic—just a reason to look at your options.

Which materials are safe?

For milk frothers, two materials have proven safe:

Glass jug Safe
  • Glass doesn’t react with hot liquids
  • No coating that can peel off
  • Transparent: you can see what’s happening
  • No wear over time
Uncoated stainless steel Safe
  • Food-grade steel (304 or 316)
  • Used in professional kitchens
  • No PFAS, PTFE, or non-stick coating
  • Note: some stainless-steel jugs still have a coating
What to look for when buying

Look for: “glass jug,” “uncoated stainless steel,” or “no non-stick coating.” Avoid: “non-stick,” “non-stick coating,” “PFOA-free” (without also saying PFAS-free), and any milk frother with a dark, smooth interior.

And ceramic coatings?

Ceramic coatings are often presented as a safe alternative, but they aren’t automatically PFAS-free. Some use PFAS as a processing aid in the manufacturing process. For milk frothers, the safest choice is simple: no coating. Glass or uncoated steel.
