Air fryers have become a staple in modern kitchens. They are quick, energy-efficient, and make it easier than ever to prepare meals at home. But while most consumers focus on convenience, researchers are increasingly examining the materials used inside these popular appliances.
According to research highlighted by the CDC, EBioMedicine, and scientists at Slovak Medical University, certain non-stick coatings may contain PFAS, a group of synthetic compounds commonly referred to as "forever chemicals."
These substances break down very slowly and can accumulate in both the environment and the human body over time, reports Unilad.
Growing concern
PFAS have long been used in cookware because of their heat-resistant and non-stick properties. However, a growing body of research has linked prolonged exposure to some PFAS compounds with a range of health concerns.

Scientists have investigated potential connections to cardiovascular disease, thyroid disorders, fertility issues, and several forms of cancer. Studies also suggest that a large proportion of the population already has detectable levels of PFAS in their bloodstream.
When the risk increases
Experts stress that air fryers themselves are not considered a major source of exposure under normal conditions. The concern primarily arises when non-stick coatings become scratched, worn, or damaged after extended use.
As these surfaces deteriorate, there may be a greater chance of small amounts of chemicals being released during cooking. For that reason, researchers recommend regularly checking air fryer baskets and trays for signs of wear.
What you can do
Those looking to reduce their exposure may consider:

- Replacing cookware with damaged non-stick coatings
- Avoiding abrasive cleaning tools that can scratch surfaces
- Choosing alternatives such as stainless steel, cast iron, or glass
Researchers are not calling for alarm, but they do encourage consumers to be mindful. Small changes in everyday habits could help reduce overall chemical exposure over the long term.
