7 Safest Non-Toxic Air Fryers Without Teflon or PFAS

Air fryers are becoming the must-have kitchen appliance in 2026. They're much healthier, reducing the fat content of your food by up to 80%. They also use less energy than a conventional oven.

But did you know that the non-stick coatings on some traditional air fryers are potentially toxic? Teflon (PTFE) and PFAS (forever chemicals) coatings can degrade over time and leach into your food.

Non-toxic air fryers help you keep "forever chemicals" out of your kitchen. They're made from safer materials like glass, stainless steel, or ceramic for all cooking and food-contact surfaces, so your food never comes into contact with harmful chemicals. They are still nonstick, but without resorting to PTFE, PFOA, and heavy metals.

As an avid home chef, I was keen to add an air fryer to my kitchen. So my team and I set out to research and test the safest non-toxic air fryer brands on the market.

Here's our list of the best air fryer options that effortlessly combine efficiency, safety, and sustainability, without damaging the planet or compromising taste or convenience.

7 Best Non-Toxic Air Fryers to Buy Online

Why It's My #1 Pick: The Our Place Wonder Oven is one of the safest air fryers on the market. This versatile appliance bakes, steams, broils, toasts, and roasts with ease.

Personal Experience: The Wonder Oven has transformed my cooking routine. The steam infusion technology ensures that every dish is perfectly cooked, retaining moisture and flavor.

It roasts a hefty 4.50 lb chicken without any problems. This doubles the cooking capacity of compact units I tested. Multiple accessories and thoughtful design make this Teflon-free air fryer both user-friendly and versatile.

Why It's Good for Large Families: The Our Place Wonder Oven Pro offers an increased 30 liter capacity and a precise digital display. The increased space makes it easy to cook larger meals or multiple items at once. The size is more than enough for our family's needs and even handles dinner parties without us needing to cook multiple batches.

The Wonder Oven Pro comes with a bake pan, fryer basket, and two wire racks, all of which are 14" wide. The racks are made from durable chromed steel, which adds to the oven's modern design and longevity.

Personal Experience: I tested the Wonder Oven Pro for six weeks because I needed a large replacement for my broken Green Pan Elite. I soon discovered that I actually prefer this to the Green Pan.

The digital touchscreen of the Wonder Oven Pro gives me precise temperature control, and I love the flexibility of 8 different cooking modes (Air Fry, Bake, Roast, Toast, Broil, Dehydrate, Proof, Reheat).

The Wonder Oven Pro is non-toxic because it does not have any PFAS or PTFE coatings on any food-contact surface. The bake pan has a ceramic nonstick coating on a cast-aluminum base, and the heating elements are made of quartz and stainless steel.

The standard Wonder Oven earned my top overall recommendation because its 12-liter capacity and compact footprint are better suited to most kitchens. The standard model costs less and weighs 11.6 lbs compared to the Pro's 18 lbs. This makes the regular Wonder Oven easier to move and store for average households.

However, the Wonder Oven Pro makes sense if you regularly cook large quantities. The 30-liter capacity is 2.5 times that of the standard model, and the extra 300 watts of power (1700W vs 1400W) help reduce heat-up times.

Why It's the Best Glass Air Fryer: The Ninja Crispi features a transparent glass design that allows you to monitor your food safely and easily. Its BPA-free and PFAS-free glass construction means no harmful chemicals come into contact with your food because glass is inherently non-reactive and has no coating.

Personal Experience: The Ninja Crispi 4-in-1 Glass Air Fryer is remarkably easy to use and clean.

You can do a lot with it, despite a relatively modest 4 Qt capacity. Its clever design means it can comfortably cook enough food for 4 to 5 people, even those with slightly larger appetites like me! Most dishes cook in 10-15 minutes.

The Crispi cooks food evenly and did a particularly good job on my favorite spicy chicken wings.

One of the key benefits I noticed during personal use is that with a glass air fryer, you can keep an eye on your food as it cooks without opening the basket and releasing heat.

The two glass bowls are super easy to clean. I use warm water and mild dish soap, but they are also dishwasher safe if you prefer.

This product is slightly cheaper than the Wonder Oven, although it has a lower capacity and fewer preset functions. But if you are attracted to the superior safety and durability of a coating-free glass air fryer, this is the best on the market right now, in my opinion.

Why It's Good for Rotisserie Chicken: The rotating rotisserie function ensures even cooking and thorough seasoning, producing restaurant-quality rotisserie chicken at home...juicy on the inside with a perfectly crispy exterior!

Personal Experience: The ease of making healthier versions of fried favorites and the convenience of its preset functions have streamlined my cooking process, giving me the confidence to try new recipes.

In my experience, this air fryer consistently delivers a satisfying food crisp on fries, chicken tenders, and other favorites, thanks to its precise temperature controls, heat efficiency, and ceramic-coated basket.

The Aria is the smallest Air Fryer I tested, although the 10Qt capacity is still large enough to fit in multiple 12" pizzas. I would say it isn't as quiet as other options. But it's powerful, did the best job of cooking chicken, and it comes with the longest warranty.

Why It's the Best Stainless Steel Air Fryer: The BLACK+DECKER Crisp' N Bake is a very sturdy steel air fryer toaster oven designed for those who need extra wide space for cooking.

Its extra-wide interior allows you to fit a whole tray of food, making it ideal for large meals or multiple dishes at once. The racks and baskets are made from durable polished stainless steel, which gives it a pleasing modern look.

Personal Experience: From toasting bread to perfection to creating crispy, air-fried delights, the BLACK+DECKER Air Fryer Toaster Oven has never let me down. 

The ease of switching between functions without sacrificing quality or taste stood out. 

But what really impressed me with this toaster oven is how well it cooks my specialty margarita pizza with hand-stretched sourdough crust.

Why It's Recommended for Versatility: The Typhur Dome 2 Air Fryer is a highly versatile model that combines air frying, convection oven, toaster, griddle, dehydrator, and self cleaning. You can use it to bake pizzas, grill steaks, make pancakes, toast bread, roast vegetables, broil proteins, and dehydrate foods using 15 different preset modes and cooking functions.

All cooking surfaces in the Typhur Dome 2 Air Fryer are made from non toxic materials (ceramic and stainless steel) for a safer cooking experience. The ceramic coating is a non-stick sand-derived, sol-gel coating, which is more environmentally sound than traditional non-stick options.

Personal Experience: The Typhur Dome 2 pleasantly surprised me with its wide, shallow design that cooked food faster than most traditional-style air fryers I tested.

I used it to cook wings, pizza, and jacket potatoes. The dual heating elements cooked everything evenly without flipping or shaking. My homemade pizzas came out crispy in just 8 minutes.

The non-toxic ceramic coating cleaned easily after each use, and the self-cleaning mode broke down grease buildup with high heat when I ran it weekly. After use, I found it equally easy to put the basket in the dishwasher or clean it with warm soapy water.

Why It's Good for Space Saving: The bella 4Qt Slim Air Fryer is a budget friendly option that takes up less space on your countertop, making it ideal for small kitchens or apartments. It features a Fits-anywhere™ system which saves up to 50% more space compared to previous bella models. But it still offers a 4-quart capacity and is free from PFAS, PFOA, PTFE, lead, or cadmium. 

Personal Experience:  I tested the bella 4Qt Slim Air Fryer with chicken, vegetables, and frozen fries. The 1300-watt power system cooked everything evenly using circular heat technology. My chicken came out crispy on the outside and juicy inside every time. The frozen fries turned golden and crunchy, just like I wanted.

The EverGood™ ceramic nonstick coating was impressive. Food did not stick during testing, and cleanup was simple. I put both the basket and tray in the dishwasher without any issues.

The bella's digital controls made cooking foolproof, and the 60-minute timer with audio alert prevented any burnt meals. Cool-touch handles kept my hands safe even when the unit was hot.

5 Models We Didn't Choose (And Why)

• Big Boss 16Qt Large Air Fryer Oven - This was my original recommendation for the best glass air fryer. I liked the 16-quart glass bowl, which I felt was ideal for families. But in recent months, it's frequently out of stock. Then I tested the Ninja Crispi 4-in-1 and was so impressed, I'd have made it my top recommendation anyway, even if the Big Boss was still readily available.
• Cosori Iconic Stainless Steel 6.5 Qt - This is an updated version of the old Cosori TurboBlaze. It's a nice little air fryer that looked great and did everything I asked it to. But it costs around 33% more than the Our Place wonder oven, and only offers around half the capacity.
• Typhur Sync Air Fryer - Another model in the impressive Typhur range. The Sync is equally non-toxic and sustainable as the Dome 2, which I recommended, and it's less than half the price. But I felt the 15-in-1 versatility of the Dome 2 justified the extra cost. Choose the Typhur Sync if you love the brand but want a more entry-level price point.
• Cuisinart Air Fryer Toaster Oven - This stainless steel air fryer compares most closely to the BLACK+DECKER 8-Slice Crisp' N Bake that I recommended. The BLACK+DECKER is around 30% cheaper and has a slightly larger capacity. I also found that the Cuisinart runs around 20 degrees too hot, which can make timing your cooking difficult and often leads to burnt edges on pizzas.
• GreenPan Clearview 10QT Double Air Fryer - I found the controls on this model to be very awkward to use. It is nowhere near as intuitive and beginner-friendly as the Our Place Wonder Oven models I recommended, despite coming in at a similar price point.

What to Look For in Non-Toxic Air Fryers

When shopping for a non-toxic air fryer, it’s essential to focus on features that prioritize your health and safety. Here’s what to look for.

• Safe Materials: The best non toxic air fryers are made from glass, stainless steel, or ceramic. These materials are naturally resistant to high heat and typically do not release toxic fumes or chemicals into your food because they do not contain PTFE and PFOA
• Minimal Plastic Components: Look for air fryers with as few plastic parts as possible, especially in food contact areas. Reducing plastic components helps prevent microplastics from contaminating your meals. Some conventional air fryers are made with plastics that can release volatile organic compounds (VOCs) when heated, posing additional health risks (Beel et al., 2023).
• Wide Temperature Range: A broad temperature range allows you to cook a variety of foods, from crispy fries to baked goods, while ensuring even heat distribution and optimal results.
• Multiple Cooking Modes: Versatile cooking modes (like air fry, bake, roast, toast, and dehydrate) make it easy to prepare a wide range of dishes in one appliance. Models like the Place Wonder Oven and Wonder Oven Pro offer impressive flexibility.
• Easy-to-Clean Design: Removable baskets, crumb trays, and wire racks that are dishwasher-safe or easy to wipe down make cleanup a breeze, encouraging regular use without hassle.
• User-Friendly Controls: Digital displays and intuitive controls help you set precise temperatures and cooking times, ensuring consistent results every time.

Popular non-toxic air fryer models, such as the Our Place Wonder Oven Pro, Ninja Crispi 4-in-1 Glass Air Fryer, and Bella Ceramic Air Fryer Toaster Oven, combine these features to deliver safe, convenient, and delicious cooking.

What Makes an Air Fryer Non-Toxic?

All of the models recommended above are classified as non-toxic, meaning they meet the following criteria.

• No PFAS/PTFE - All models must be made without PFAS (including PTFE and PFOA), which means you avoid toxic fumes from overheated Teflon coatings and other risks associated with forever chemical exposure. There is a potential risk of exposure to chemicals like PFAS and PFOA from non-stick coatings, especially if these coatings are damaged or overheated.
• Non-reactive materials - All food contact surfaces must be made of materials such as glass and stainless steel that don't leach chemicals into food, even when scratched.

Although they are PFAS-free, "non-toxic" ceramic coatings can still wear out over time and need to be treated with care to prolong their lifespan. Glass and stainless steel models are often considered the safest long-term option as they do not have any coatings.

The main consideration is to avoid potentially toxic nonstick coatings like Teflon.

Which Nonstick Coatings Can Be Toxic?

The main groups of chemicals associated with the nonstick coating used in some air fryers are Teflon (PTFE), which is a subset of PFAS (also known as forever chemicals), and PFOA, a type of PFAS.

To minimize toxic exposure, it is recommended to avoid air fryers with PFOA, PTFE, phthalates, and BPA.

The air fryers listed in this article do not contain any of the following.

Teflon (PTFE)

Teflon is a brand name for a polymer known as polytetrafluoroethylene (PTFE). It is used in cookware as a non-stick coating.

Our guide to the toxicity of nonstick kitchenware explains how PTFE releases toxic fumes when overheated and can leach chemicals and microplastics into food when scratched or damaged.

There is a potential risk of exposure to toxic fumes and chemicals from PTFE coatings, especially when the surface is overheated or damaged.

"At normal cooking temperatures, PTFE-coated cookware releases various gases and chemicals that present mild to severe toxicity," (Sajid M, Ilyas M., 2017).

While PTFE is relatively inert and safe in lower temperatures, its degradation at high temperatures can release harmful fumes. These fumes have been known to cause polymer fume fever (also known as 'Teflon flu') in humans and can be fatal to birds (Shimizu et al, 2012).

Environmentally, the production and disposal of PTFE-coated products can contribute to pollution and waste.

PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals used in various consumer products, including nonstick cookware coatings (EPA).

Joseph G. Allen of Harvard T.H. Chan School of Public Health first described PFAS as 'forever chemicals' due to their persistence in the environment and the human body.

Exposure to elevated PFAS levels is linked to health issues, such as increased cholesterol, high blood pressure, developmental effects, reduced immune response, and certain cancers. (Fenton et al., 2021). These elevated levels can result from exposure to PFAS that leach into food or air, especially when non-stick coatings in air fryers are damaged or overheated.

Some types of PFAS, including PFOA and PFOS, are classified as carcinogenic to humans by the International Agency for Research on Cancer, based on evidence from animal studies and human exposure (IARC).

The environmental impact of PFAS is equally concerning. They can accumulate and remain in the environment for an extended period, contaminating soil, water, and air.

PFOA

Major manufacturers have phased out perfluorooctanoic acid (PFOA), once commonly used in the manufacturing of nonstick coatings, due to health concerns. PFOA exposure has been associated with various adverse health effects, including potential risks of cancer (American Cancer Society).

From an environmental standpoint, PFOA is persistent and can lead to long-term contamination of water and soil. It doesn't break down easily in the environment, leading to widespread global distribution, even in remote areas.

Bisphenol A (BPA)

Some older air fyers may incorporate components or baskets made from polycarbonate plastic that contains BPA.

Be careful of old, cheap, or second-hand models, which may have polycarbonate in food contact areas, because BPA can migrate into food (USDA).

To ensure safety, always choose air fryers with BPA-free food contact surfaces.

BPA isn't an issue if you're buying new. The brands recommended above are all BPA-free and have non-toxic coatings as described below.

What Are the Safest Non-Toxic Coatings?

Ceramic Coatings

Ceramic coatings are primarily made from silicon dioxide (silica) derived from sand.

These coatings offer a nonstick surface without the potentially harmful chemicals found in some traditional coatings.

Silicone-Based Coatings

Another innovative option in nonstick technology is silicone-based coatings.

Silicone, a synthetic rubber made from silicon and oxygen, offers a flexible, heat-resistant, nonstick surface.

Silicone coatings are known for their durability and resistance to high temperatures. They don't degrade quickly, which means a longer lifespan and less frequent need for replacement.

No Coatings at All

Air fryers made from glass (such as the Ninja Crispi) or polished stainless steel (such as the BLACK+DECKER) do not require coatings.

Both glass and stainless steel are stable, non-porous, and inert, meaning they do not react with food or release harmful chemicals.

Air fryers made from glass, stainless steel, or ceramic are generally more durable and require proper maintenance to stay in good condition.

Are There Any Disadvantages of PTFE-Free Non-Stick Coatings?

PFA and PTFE coatings may be more durable and stay more non-stick for longer than most PTFE-free “ceramic” non-stick coatings, largely due to differences in the materials used for the cooking surfaces.

A 2024 study compared Teflon to sol-gel ceramic coatings in a pancake-batter detachment test (Guerrero-Vacas et al., 2024). The results show some performance reduction in non-toxic coatings in the following areas.

• Food release: PTFE coatings release food more easily, especially after lots of use. Ceramic, glass, or stainless steel surfaces may not release food as easily as PTFE.
• Durability: PTFE coatings keep their non-stick performance through more cooking cycles in lab tests, while ceramic cooking surfaces may wear down faster.

If your main priority is the strongest, longest-lasting non-stick performance, PTFE (Teflon-type) tends to perform better than PTFE-free ceramic coatings. But if you prioritize health and a chemical-free kitchen environment, then non-toxic cookware with safer cooking surfaces is a better choice, and ceramic coatings are generally considered more environmentally sound.

Whichever type of air fryer you choose, it can offer benefits over other cooking methods.

What Are the Benefits of Air Fryers?

Air fryers are healthier than frying food with oil, and better for the environment than cooking in conventional ovens.

However, it's important to note that acrylamide, a potentially harmful compound, can form when starchy foods like potatoes are cooked at high temperatures, which is a concern with air fryers.

Choosing a non-toxic air fryer means you can enjoy all the crispy, delicious results of air frying without worrying about toxic air or the potential health or environmental risks associated with conventional models.

Health Benefits

• Reduced Fat Content: Traditional deep frying involves submerging food in oil, significantly increasing the fat content. Air fryers reduce the fat content of meals by 70% to 80% compared to oil frying (health.com; Feng et al., 2020). They offer a healthier alternative without sacrificing taste.
• Lower Calorie Intake: With less oil, air-fried foods are lower in calories (Medical News Today). This makes air frying an excellent option if you're monitoring your calorie intake but don't want to give up all your favorite fried foods.

Environmental Benefits

From an environmental standpoint, air fryers have a couple of notable benefits:

• Energy Efficiency: Air fryers typically cook food faster and at lower temperatures than conventional convection ovens. They're more energy-efficient, using up to half the energy of a traditional oven, especially when cooking for one or two people (Which?; Energy Saving Trust).
• Reduced Oil Usage and Waste: By minimizing oil usage, air fryers promote better health and reduce oil waste, a significant environmental concern (Téllez-Morales et al., 2024).

What Are the Different Types of Air Fryers?

Basket, Oven-Style (Air Fryer Toaster Ovens), and Paddle-Type are the three most common types of air fryers. Each has a different appearance and primary usage as listed below.

• Basket Air Fryers: The most traditional type, featuring a pull-out drawer and basket where food is placed for cooking. They use rapid air circulation technology to cook food evenly.
• Oven-Style (Air Fryer Toaster Ovens): These air fryers resemble mini ovens with shelves or racks, offering more space and flexibility. They often come with additional functions like baking, toasting, and rotisserie. Many large-capacity models can accommodate a whole chicken for roasting or baking, making them ideal for preparing family-sized meals.
• Paddle-Type Air Fryers: These air fryers use a stirring paddle to continuously move food during cooking. This ensures even cooking without manual intervention.
• Halogen Air Fryers: Halogen air fryers use a halogen bulb as their heating element, combined with a fan to circulate hot air.
• Digital vs. Manual: Digital air fryers feature touch screens and preset programs for various foods, offering precise control over cooking times and temperatures. Manual air fryers use dials to control time and temperature.

What Are Some Tips for Effective and Safe Air Fryer Use?

To get the most out of your air fryer, my top tips are to be realistic about what it can and cannot do, learn how to operate it safely, and know how to maintain it.

Set Expectations for Air Fryer Use

It's important to approach air frying with realistic expectations.

Air fryers can produce results similar to frying with less oil, but they might not replicate the exact taste or texture of your favorite deep-fried foods.

How to Operate Your Air Fryer Safely

1. Preheat Properly: Just like your oven, preheating your air fryer can lead to better cooking results. It ensures that your food starts cooking immediately and evenly once it hits the basket.
2. Don't Overcrowd: Give your food enough room to cook. Overcrowding can lead to uneven cooking and less crispiness. Cook in batches if necessary.
3. Use Appropriate Accessories: If you use any accessories or inserts (such as baking pans, grill racks, and tongs), ensure they're designed for air fryers. This ensures safe operation and the integrity of your appliance.

How to Clean and Maintain Your Air Fryer

1. Set a Regular Cleaning Schedule: Keeping your air fryer clean is not just about hygiene; it's about maintaining performance. Clean the basket, pan, and interior after each use. Most air fryers have dishwasher-safe parts, but check your manual to be sure.
2. Check for Wear and Tear: Regularly inspect your air fryer for any signs of wear, especially the basket and nonstick coating. Worn ceramic affects cooking performance but doesn't carry the same chemical risks as degraded PTFE. Damaged PTFE coatings are a health and safety concern, which is precisely why we recommend avoiding them.
3. Avoid Abrasive Cleaners: Avoid using abrasive materials that could scratch or damage the nonstick coating. Using low-calorie oil sprays that contain lecithin can damage the non-stick coating of air fryers, leading to the release of harmful chemicals. Gentle, soapy water and a soft sponge or cloth are usually all you need.

How to Dispose of an Old or Broken Air Fryer

If your air fryer is damaged or broken in any way, you should stop using it to avoid potential toxic exposure.

Check with local recycling programs to see if they accept small appliances. Some manufacturers even offer take-back or recycling programs for their products.

We all need to do whatever we can to stop harmful materials from ending up in landfills.

Still have questions about nontoxic air fryers? Based on common questions from readers, here are the key answers.

What are the best air fryers with ceramic coating?

The Our Place Wonder Oven, Wonder Oven Pro, Aria 10Qt, Typhur Dome 2, and bella 4Qt all feature PTFE-free ceramic non-stick coatings.

Does air frying produce acrylamides?

Yes, air frying can produce acrylamide, especially when cooking starchy foods like potatoes at high temperatures. Acrylamide forms when starchy foods are cooked at high temperatures in air fryers, which is a concern because acrylamide is a probable human carcinogen.

Reducing cooking time, avoiding overly browning or burning foods, and opting for lower cooking temperatures can help minimize acrylamide formation in air-fried foods.

Can I replace my conventional oven with a non-toxic air fryer?

Yes, you can replace your oven with an air fryer. However, while they can complement or substitute certain oven tasks, they may not completely replace a conventional oven's full range of capabilities, especially for large-scale cooking.

Can I cook frozen foods in a non-toxic air fryer?

Yes, non-toxic air fryers are excellent for cooking frozen foods efficiently.

Do air fryers emit harmful radiation?

No, air fryers cook food using rapidly circulating hot air without microwave technology or emitting harmful radiation.

Are Ninja XL air fryers toxic?

It is unclear whether Ninja air fryers are likely to release toxic chemicals because the brand has not yet released sufficient information about the composition of its nonstick coating. For that reason, I cannot yet recommend Ninja's ceramic-coated products - although their glass model is one that I recommend.

The Final Word

Switching to a non-toxic air fryer is a smart move for anyone who values health, safety, and great-tasting food.

My experience and rigorous testing show that non-toxic air frying is a great way to enjoy your favorite fried foods without compromising taste, health, or environmental ethics.

The Our Place Wonder Oven is my top pick because I love the steam function and the impressive capacity of such a compact unit. It's also free from harmful chemicals like PFAS, PFOA, and PTFE, which is a huge plus.

If you have a large family and need extra capacity, the Our Place Wonder Oven Pro is a great choice that also benefits from 8 preset functions and a digital display.

For those who live alone or have limited counter space, such as in small apartments, I recommend the bella 4Qt Slim Air Fryer. This is also a great choice if you need a non-toxic option on a budget.
