What the Cosori air fryer is made of and whether it poses health risks

The Cosori air fryer uses a combination of materials common to most air fryers: a stainless steel or plastic exterior housing, an aluminum or steel cooking basket, and a non-stick coating on the basket interior. The non-stick surface is typically PTFE-based (polytetrafluoroethylene, the same material used in Teflon cookware). At normal air fryer operating temperatures—around 400°F—PTFE coatings are considered safe by the FDA and do not release harmful fumes. The risk of chemical release only becomes real if the coating is damaged and the temperature exceeds 500°F, which Cosori models do not reach.

The plastic housing and any plastic components are food-contact safe plastics designed to withstand heat. The basket itself does not come into contact with food directly in most models—food sits on the basket surface, which is the non-stick coating. If you are concerned about the non-stick coating specifically, you can line the basket with parchment paper or an air fryer silicone mat, which eliminates direct contact entirely.

Key Takeaways

  • Cosori air fryers use PTFE non-stick coatings that are FDA-approved and safe at the temperatures these machines reach (typically under 450°F).
  • The risk of non-stick coating breakdown only occurs above 500°F or if the coating is visibly scratched or peeling, neither of which happens in normal use.
  • You can further reduce any concern by using parchment paper or silicone mats inside the basket to avoid direct contact with the non-stick surface.
  • Cosori does not publish detailed material specifications on their website, so contacting their customer service directly can confirm the exact coating type for your specific model.

How non-stick coatings work and when they become unsafe

Non-stick coatings like PTFE are polymers—long chains of molecules bonded together. At temperatures below 500°F, these bonds remain stable and the coating does not break down or release particles into food. The FDA has reviewed PTFE safety extensively and concluded that cookware with intact PTFE coatings poses no health risk during normal cooking. Air fryers operate at lower temperatures than stovetop cooking, so the risk is even lower.

The concern people often raise is about PTFE fumes, which can occur if a non-stick pan is left empty on a stovetop and overheated to 600°F or higher. This scenario does not explore to air fryers because the heating element is enclosed, the temperature is capped by the machine's design, and food is present (which also helps regulate temperature). A damaged or peeling coating is a separate issue—if you see flaking, the basket should be replaced, but this is rare with Cosori baskets under normal use.

What Cosori publishes about their materials

Cosori's product pages and user manuals do not always specify the exact type of non-stick coating or the material composition of every component. Their customer service team can provide this information if you contact them directly through their website or the phone number in your manual. Most Cosori models use the same basket design across product lines, so if you own one model, the information applies to similar sizes as well.

If you want to verify the coating type before purchase, check the product listing on Amazon or Cosori's official site—some listings include material details in the specifications section. If the information is not there, a quick email to Cosori support will get you a direct answer about whether the basket is PTFE, ceramic, or another coating.

How to inspect your basket for damage

Check your Cosori basket every few months by looking at the interior surface under good light. Run your finger gently across the bottom and sides—you should feel a smooth, uniform surface. If you see white or gray flaking, peeling, or rough patches, the coating is compromised and the basket should be replaced. Cosori sells replacement baskets separately, and they are inexpensive compared to buying a new unit.

Damage usually happens from metal utensils scraping the surface or from dropping the basket. To prevent this, always use silicone, wood, or plastic utensils when moving food around inside the air fryer. Wash the basket by hand rather than in the dishwasher, even if the manual says it is dishwasher-safe—hand washing extends the life of the coating significantly. Avoid stacking other items on top of the basket when it is not in the machine.

Comparing Cosori to other air fryer brands on material safety

Most mainstream air fryer brands—when ready Pot, Ninja, Philips, and others—use the same PTFE-based non-stick coatings as Cosori. Some brands offer ceramic-coated baskets as an alternative, which are also safe but can wear faster and are more expensive. The difference between brands is usually in build quality and how long the coating lasts, not in the safety of the coating itself at normal operating temperatures.

If you prefer to avoid PTFE entirely, some air fryer models use ceramic or stainless steel baskets without any non-stick coating. These require more oil to prevent sticking and are harder to clean, but they eliminate the non-stick coating question altogether. Cosori does not currently offer a ceramic-basket model, so if that is important to you, you would need to choose a different brand.

What to do if you are still concerned

If you own a Cosori air fryer and want to eliminate any contact with the non-stick coating, the simplest solution is to use parchment paper or an air fryer silicone mat inside the basket. These are inexpensive, widely available, and do not affect cooking performance. Make sure the mat or paper does not block the air vents at the bottom of the basket, as airflow is what makes the air fryer work.

Another option is to cook foods that naturally do not stick—roasted vegetables, meat with skin, frozen foods—which require less reliance on the non-stick surface. You can also increase the oil content slightly when cooking items prone to sticking, which reduces contact between food and the coating.

Frequently Asked Questions

Does Cosori use PTFE or ceramic non-stick coating?

Most Cosori models use PTFE-based non-stick coatings, but Cosori does not always specify this on their product pages. Contact Cosori customer service with your model number to confirm the exact coating type for your unit.

Is it safe to use a Cosori air fryer every day?

Yes. Daily use at normal temperatures does not degrade the coating or pose any health risk. The coating is designed to withstand hundreds of hours of use. Inspect the basket occasionally for damage, and hand-wash it to extend the coating's life.

What happens if I accidentally scratch the non-stick coating?

A small scratch or minor damage does not make the air fryer unsafe to use. The risk only becomes real if the coating is visibly peeling or flaking in large areas. If that happens, replace the basket. Minor scratches do not require replacement.

Can I use metal utensils in my Cosori air fryer?

Metal utensils will scratch the non-stick coating over time. Use silicone, wood, or plastic utensils instead. This straightforward habit extends the life of the basket significantly and reduces the chance of coating damage.

Is parchment paper safe to use in an air fryer?

Yes, parchment paper is safe in air fryers as long as it does not block the air vents. Cut it to fit inside the basket and weigh it down with food so it does not blow around. Some people prefer silicone mats, which are reusable and do the same job.
