Nickel Allergy and Stainless Steel Air Fryers: What We Found
If you have a stainless steel allergy, meaning a nickel allergy, please ask your doctor first. We found no measurement of nickel in an air fryer, so we can't tell you how one compares. This page shows what exists and where it stops, so you can bring the facts along.

The short answer
We found no measurement in an air fryer, so we can't answer for your model. One study measured nickel up to 26 times higher in tomato sauce after six hours of simmering at 85 °C (185 °F) in a stainless pot. That is acidic sauce in a pot, in contact for hours. If you have a nickel allergy, ask your doctor.

We are not doctors and we have no lab. Nothing here is medical advice.
What did the study find?
The study most people mean was published in 2013. Researchers cooked store-bought tomato sauce in stainless steel for 2 to 20 hours and measured the sauce.
- After six hours at 85 °C (185 °F), nickel was up to 26 times higher and chromium up to 7 times higher.
- New steel gave the highest amounts. They levelled off after about six rounds of cooking.
- The authors say stainless steel cookware “can be an overlooked source of nickel and chromium”, depending on the steel type, cooking time and how much it has been used.
Where does the study stop?
- It used acidic sauce, which is a special case.
- It used a pot, and the food touched the steel the whole time.
- It has no air fryer data, and we found none anywhere else.
So we can't say whether an air fryer gives off more, less or the same. Some websites say an air fryer must give off less. We found nothing behind that, so we don't repeat it.
Who should I ask?
The American Academy of Dermatology says nickel is one of the most common causes of allergic skin reactions. It advises seeing a board-certified dermatologist for a proper diagnosis. Its page is about jewelry and household items, not air fryers.
Bring these to your doctor:
- The model you own or are thinking about.
- Which parts touch the food, and what the brand says about each.
- The limits of the study above.
Where does stainless actually sit on an air fryer?
On most models, stainless describes the outside. Check the basket and the inside walls separately.
We couldn't find a brand document that describes an uncoated stainless drawer or oven basket as the main cooking part. Fritaire's page says its extras, including a tumbling basket, are “Non-Coated” 304 stainless steel, in a glass-bowl fryer. That describes what we could read, not every product on sale.
Our Place lists its oven as “Stainless steel” and its basket and rack as “Chromed steel”, which is a plated finish. Many other brands don't say what the metal is. You could ask: “Which metal is each part that touches food made of, and is it coated?” How to check an air fryer's coating shows where to look.
What about glass?
Some people prefer a glass bowl. Glass air fryers compares them by what brands say. The bowl is glass, but check the plate, lid and handles, since racks may be metal. We make no claim that any model suits a nickel allergy, so raise it with your doctor too.
For the wider question, see is stainless steel “non-toxic”? and the material table.
Common questions
Which air fryer should I buy with a nickel allergy?
We can't tell you. We found no measurement in any air fryer, and this is a medical question about you. Ask your doctor first. After that, our material table shows what each brand says about each part.
Do people with a nickel allergy need to avoid stainless steel?
That's a question for your doctor. The study's authors write that advising people with a nickel sensitivity to avoid stainless steel may be prudent, and that whether it helps is not known. That is one cautious remark about cookware, not a rule, and it isn't about air fryers.
Does stainless steel get nickel into food?
It can, in one study of tomato sauce simmered for hours in a pot. We found no air fryer data.
