Air fryers have become one of the most popular kitchen appliances in recent years thanks to their convenience, energy efficiency, and ability to cook food with less oil. However, health experts are raising concerns about certain air fryers that may contain substances known as “forever chemicals.” These chemicals, called PFAS (per- and polyfluoroalkyl substances), are commonly used in non-stick coatings because they resist heat, grease, and water. While they help prevent food from sticking, scientists have increasingly questioned their long-term impact on human health.
What Are “Forever Chemicals”?
PFAS are a large group of synthetic chemicals that have been used in consumer products for decades. They are often referred to as “forever chemicals” because they break down extremely slowly in the environment and can remain in the human body for many years. Research has found PFAS in water supplies, food packaging, household products, and even in the blood of most people tested. Their widespread presence has made them a growing concern for scientists and public health officials worldwide.
Why Air Fryers Are Part of the Discussion
The concern surrounding air fryers focuses primarily on models that use PFAS-containing non-stick coatings inside cooking baskets and trays.Experts say that under normal cooking conditions, the amount of PFAS released from an intact coating is believed to be relatively low. However, problems can arise when the non-stick surface becomes scratched, chipped, or damaged through repeated use. In such cases, tiny particles from the coating may be released during cooking. Higher temperatures can also increase concerns. Some studies suggest that prolonged exposure to very high heat may affect the structure of non-stick coatings, although air fryers typically operate below temperatures associated with significant degradation.
Potential Health Risks
Scientists continue to study PFAS exposure, but a growing body of research has linked long-term exposure to a variety of health concerns. Studies have associated certain PFAS compounds with increased risks of thyroid disorders, fertility problems, high cholesterol, hypertension, cardiovascular disease, liver and kidney damage, and some forms of cancer. Researchers have also expressed concern about the potential impact on fetal development and infant health because PFAS can be transferred during pregnancy and through breast milk. Importantly, these findings relate to PFAS exposure in general rather than air fryers specifically. Experts emphasize that air fryers are only one potential source among many everyday exposures.
Should Air Fryer Owners Be Worried?
Most specialists do not recommend throwing away an air fryer simply because it has a non-stick coating. Many experts note that modern air fryers remain safe when used correctly and that intact coatings are not believed to release significant amounts of PFAS during normal cooking. The greater concern is cumulative exposure from multiple sources over many years rather than occasional use of a well-maintained appliance.
How to Reduce Your Risk
There are several simple steps consumers can take to minimize potential exposure:
Avoid using metal utensils that may scratch the basket.
Replace air fryer baskets that show significant wear or damage.
Follow manufacturer temperature guidelines.
Clean the appliance with non-abrasive materials.
Consider ceramic-coated or stainless-steel models if purchasing a new air fryer.
The Bottom Line
Air fryers themselves are not considered inherently dangerous, and many health experts still view them as a healthier alternative to deep frying. However, growing awareness of PFAS has prompted consumers to pay closer attention to the materials used in their cookware and kitchen appliances. While current evidence suggests that a properly maintained air fryer poses a relatively low risk, experts agree that reducing unnecessary exposure to “forever chemicals” wherever possible is a sensible precaution.
