No, many modern air fryers use ceramic or stainless steel and are free from antimony, though cheap plastic models may use it in casings.
You bought an air fryer to eat better. You wanted crispy fries without the oil bath. But now you read headlines about hidden toxins, and the panic sets in. The idea that your healthy appliance might leak chemicals into your dinner is scary. Antimony is a heavy metal often found in plastics, and heat accelerates chemical leaching.
The good news is that you have choices. Not every machine on the shelf carries this risk. Understanding where manufacturers use this metal helps you avoid it. This guide breaks down exactly where antimony hides, which materials are safe, and how to pick a unit that keeps your food pure.
The Role Of Antimony In Kitchen Appliances
Antimony is not a cooking ingredient. It is a chemical element used primarily in industrial applications. In the context of kitchen gadgets, you usually find antimony trioxide. Manufacturers use this compound as a flame retardant in plastics and as a catalyst to create polyethylene terephthalate (PET) plastic.
Your air fryer gets hot. To prevent the outer plastic shell from melting or catching fire, factories add flame retardants. If the unit is cheap and made almost entirely of plastic, the risk of antimony presence increases. The concern is not usually the metal basket itself, but the surrounding materials that heat up during operation.
When plastic heats up, it can off-gas. If you ever smelled that distinct “burning plastic” odor from a new appliance, you smelled volatile organic compounds (VOCs) releasing into the air. Antimony can be part of that chemical release. However, this does not mean it is directly touching your french fries.
Do All Air Fryers Have Antimony In Them? A Closer Look
It is a myth that every single unit contains this metal. Do all air fryers have antimony in them? No. High-end models constructed from stainless steel, glass, or ceramic often bypass the heavy use of treated plastics found in budget models. The internal cooking chamber is the most critical area. If your food touches stainless steel or ceramic, your exposure risk drops to near zero.
The confusion often comes from the exterior housing. Even a stainless steel air fryer might have plastic feet, handles, or control panels. But these parts do not contact your food. The primary danger zone is the basket and the tray. If those components are free from low-grade plastics and coatings, you are generally safe.
Antimony Risk Levels By Material Type
Different materials pose different risks. This table breaks down the components of an air fryer and where you might find antimony or other concerns. Use this to scan your current machine.
| Component Material | Antimony Risk Level | Common Location In Unit |
|---|---|---|
| Polypropylene (Plastic) | Moderate to High | Outer housing, cheap baskets |
| Stainless Steel (304 Grade) | None | Cooking chamber, racks, housing |
| Borosilicate Glass | None | Bowl, viewing windows |
| Ceramic Coating | Very Low | Non-stick basket surface |
| Teflon (PTFE) | Low (Uses different chemicals) | Standard non-stick baskets |
| Silicone Bumpers | Very Low | Tray stabilizers, feet |
| Aluminum (Bare) | None (concerns are aluminum) | Heating elements, fan blades |
| Polycarbonate | Moderate | Display screens, buttons |
Why Manufacturers Use Antimony In Plastics
Cost drives production decisions. Plastic is cheap, lightweight, and moldable. But plastic melts. To pass safety regulations regarding fire hazards, companies treat the plastic housing with chemicals. Antimony trioxide works in synergy with halogenated flame retardants to stop fires before they spread.
This is standard for electronics like TVs or computers. The problem arises when we apply the same logic to things that cook our lunch. An air fryer circulates superheated air. That air moves over the heating element, through the basket, and past the plastic walls. If those walls contain antimony-based retardants, the high heat could theoretically encourage migration.
A study on PET bottles showed that antimony leaching increases with temperature. While an air fryer is not a water bottle, the principle of heat-inducing migration remains valid. This is why the “plastic smell” is a red flag. It indicates the material is chemically active under heat.
Distinguishing Between The Housing And The Basket
You must separate the machine into two zones: the food zone and the structural zone. The structural zone includes the outer shell, the cord, and the electronics. This area often contains plastic. Unless you lick the outside of your fryer, direct ingestion is unlikely. The risk here is inhalation of fumes if the plastic degrades.
The food zone includes the basket, the crisping tray, and the heating element cover. This is where safety matters most. Cheap generic brands might use a plastic-heavy design even inside the cooking chamber. Avoid these. You want metals and ceramics here. If the manual warns of a strong chemical smell that persists after the first run, return it. That is off-gassing you do not want in your kitchen.
Health Risks Of Antimony Exposure
Antimony toxicity is real. Short-term exposure to high levels can cause nausea, vomiting, and diarrhea. Long-term inhalation of antimony dust is linked to heart and lung problems. The Agency for Toxic Substances and Disease Registry (ATSDR) notes that antimony attaches to particles in the air, which we then breathe.
In an air fryer context, you are not working in a mine or a factory. The levels are trace. However, bioaccumulation is a valid concern for health-conscious families. Why add even a microgram of heavy metal to your diet if you can avoid it? The goal is to reduce your total toxic load. Eliminating a plastic-heavy heating appliance is an easy win.
Confusion With Teflon And PFAS
Many users confuse antimony with PFOA or PTFE (Teflon). They are different beasts. Teflon uses fluoropolymers to create a slick surface. Antimony is a metal used in the plastic structure or as a catalyst. You can have an antimony-free fryer that still uses Teflon. You can also have a ceramic fryer (Teflon-free) that has a plastic shell containing antimony. Ideally, you want to avoid both.
Identifying Safe Air Fryer Materials
To ensure your unit is clean, look for specific materials. Brands are getting better at transparency because buyers like you are asking questions. Here is what to look for on the box.
Stainless Steel Construction
Food grade stainless steel, often labeled as 304 or 18/10, is the gold standard. It does not require a chemical coating to be safe. It withstands high heat without off-gassing. Some units look like stainless steel but are just plastic painted silver. Knock on the side. If it sounds hollow and plastic, it is just a facade. Real steel feels cold and solid.
Ceramic Coatings
Ceramic is a mineral-based non-stick option. It is made from silica (sand). It does not use PFOA or PTFE, and it does not require antimony to bond to the metal basket. Companies like Ninja and Philips often use high-grade ceramic coatings in their premium lines. These are generally inert, meaning they do not react with your food chemically.
Glass Air Fryers
Glass is the ultimate neutral material. A glass bowl air fryer lets you see the food cooking and contains zero metals or plastics in the food zone. These used to be rare but are gaining popularity. The lid usually contains the heating element and fan. As long as the underside of the lid is steel, a glass fryer is one of the safest bets against antimony.
How To Test Your Current Air Fryer
You might already own a machine and worry about it. You do not always need to toss it. First, do a smell test. Run the empty fryer at 400°F for 20 minutes. If the room smells like burning tires or sweet chemicals, that is plastic degradation. If it smells clean or just like hot metal, you are in better shape.
Next, check the basket condition. If the coating is chipping, the underlying metal is exposed. While the base metal is usually aluminum (safe but reactive with acids) or steel, chipping indicates the coating is failing. If pieces of coating flake off, you end up eating them. Replace any basket that shows signs of peeling.
Check the product manual or the manufacturer’s website. Search for “California Prop 65” warnings. California requires companies to label products containing chemicals known to cause cancer or reproductive harm. Antimony oxide is on that list. If you see a Prop 65 warning on your box, it suggests the presence of heavy metals or harsh chemicals.
Regulatory Standards And Safety Claims
In the United States, the FDA regulates food contact surfaces. They have strict limits on what can leach from a pan into food. However, they do not strictly regulate the *housing* of an appliance unless it poses an immediate danger. This is a loophole. The basket passes the test, but the plastic shell 2 inches away might be full of flame retardants.
European standards (REACH) are often stricter regarding hazardous substances in electronics. Buying a model that sells well in the EU market can sometimes offer a higher safety baseline. Look for RoHS compliance (Restriction of Hazardous Substances), which limits lead, mercury, and cadmium, though antimony has specific allowances.
Do All Air Fryers Have Antimony In Them? The Final Verdict
We circle back to the main question: do all air fryers have antimony in them? The answer remains a firm no. You can find units built with integrity. The market splits into two categories: cheap mass-produced units that rely on plastic engineering, and health-focused units that prioritize inert materials.
The price difference is real. A $30 air fryer likely cuts corners on material safety. A $150 unit typically invests in better steel and higher-grade coatings. When you pay more, you are often paying for what is *not* in the product.
Alternatives To Plastic-Heavy Models
If you are ready to switch, focus on “oven style” air fryers. These look like miniature toaster ovens. They usually have a stainless steel interior, metal racks, and a glass door. The amount of plastic near the heating elements is minimal compared to the “basket style” drawers that slide into a plastic cave.
Another strong option is the stainless steel basket style. Some brands offer a completely steel basket without non-stick coatings. You might have to scrub a bit harder to clean off cheese, but you gain peace of mind knowing no chemical coating exists to degrade over time.
Actionable Steps For A Non-Toxic Kitchen
You want to cook tonight without worry. Use this checklist to evaluate your next purchase or audit your current setup. This simplifies the chemistry into a simple “Yes” or “No” decision process.

| Chipping Basket Coating | Unsafe | Direct ingestion of coating particles. |
| “PFOA Free” Label | Good start | Does not guarantee plastic-free housing. |
Maintaining Your Safe Air Fryer
Once you buy a clean machine, keep it that way. Avoid abrasive scrubbers like steel wool on ceramic coatings. Even safe coatings can fail if scratched deep enough. Use silicone utensils rather than metal tongs. Metal scratches the surface, creating traps for bacteria and damaging the barrier between your food and the base metal.
Clean the heating element regularly. Grease buildup on the coil burns and smokes. This smoke is carcinogenic, regardless of what the machine is made of. Wipe down the interior roof of the fryer with a damp cloth after it cools. A clean machine runs more efficiently and keeps the air quality in your kitchen pure.
Ventilation Is Key
Even with the safest materials, high-heat cooking creates fumes from the oils and fats in the food itself. Always run your air fryer under your kitchen range hood or near an open window. Moving air reduces the concentration of any potential airborne particles, whether from the food or the machine.
See studies on heat-induced chemical migration to understand why ventilation matters during high-temperature cooking. It is a simple habit that protects your lungs.
Making The Right Choice
You have the power to choose what sits on your counter. Antimony is a valid concern in cheap plastics, but it is not an unavoidable evil. By shifting your focus to stainless steel, glass, and high-quality ceramic, you bypass the risk entirely. Read the labels, check the materials, and trust your nose. If it smells like a chemical factory, it does not belong in your home. Real food deserves real materials.
