7 Best Non-Toxic Glass Air Fryers Without PFAS, Reviewed

I found and tested the best non-toxic glass air fryers in 2025 that are completely free from harmful chemicals like PTFE, PFOA, and Teflon. But this review wasn’t easy. While many air fryers claim to be “safe,” I discovered that several still use non-stick coatings or materials that can leach toxins into your food, especially when heated above 170°C. Food-contact parts like PBAS plastic lids, silicone seals, or Teflon-coated racks can release harmful chemicals, according to the Indian Council for Medical Research (ICMR). These harmful compounds affect thyroid health and have been connected to the development of serious conditions like cancer.

As someone living with Hashimoto’s, a thyroid condition sensitive to chemical exposure, I’m especially cautious about what I bring into my home and kitchen. That’s why finding a truly healthy, PFAS-free glass air fryer has been a top priority for me. After testing more than a dozen models, I was shocked to find that over five either underperformed, were difficult to clean, or simply didn’t live up to their claims.

In this guide, I’ll share the safest, most reliable glass air fryers that passed my strict tests, so you can cook with confidence and protect your health.

How I Tested These Glass Air Fryers

Different foods: For several weeks, I roasted vegetables like crispy Brussels sprouts, reheated leftover pasta, rotisserie-style chicken, frozen snacks like mozzarella sticks, and classic French fries. I want to see how these glass air fryers perform with dishes that most people prepare on a weekly basis. 

Cooking capabilities and evenness: I focus on key factors that affect daily cooking: Does the air fryer keep a steady temperature throughout the cooking time? How fast does it cook? And does it brown or crisp food evenly, or leave cold spots? For example, one model struggled to crisp fries on the top rack, while another delivered perfectly golden results every time.

Toxic-Free Food Contact Materials: But cooking performance isn’t the whole story. I only include non-toxic glass air fryers that come with clear certifications showing they are PFAS-free and contain no PTFE, PFOA, BPA, or any chemicals flagged under California’s Prop 65 list. I found their product labels, safety data sheets, and even reached out to manufacturers directly to verify these claims.  

Options for large families and two-person households: Capacity is another big factor. While we are a two-person household, I tested small models perfect for singles or couples, as well as larger units that can cook meals for a family of four or more. I pay attention to how much food actually fits and how easy it is to load and unload baskets without making a mess. Sometimes brands oversell capacity.

Ease of programming: I also evaluate how intuitive the controls are: Are the buttons and dials easy to read? Do presets like “chicken” or “frozen fries” actually work without guesswork? And after cooking, how tough is the cleanup? Glass bowls should wipe clean easily, not trap grease or odors.

Durability matters too. I test how sturdy the lid and basket feel after daily use. All flimsy plastics and rattling parts got disqualified. Plus, I research brand reputation for customer service, checking if they provide warranties, replacement parts, or responsive support when things go wrong.

Now, before we dive into the top best non-toxic glass air fryers in 2025, let me explain why avoiding PFAS, PTFE, and PFOA in kitchen appliances is so important.

What are PFAS, PFOA, and PFOS in Air Fryers?

PFAS (per- and polyfluoroalkyl substances) are a large family of over 12,000 synthetic chemicals used since the 1940s to make products resistant to heat, oil, water, and stains. You’ll find them in pretty much everything from waterproof jackets to dental floss—and yes, many air fryer coatings.

One of the most common types of PFAS is PTFE, better known as Teflon. It’s used to create “nonstick” cooking surfaces. The problem? PTFE coatings begin to degrade at around 500°F, and many air fryers reach temperatures close to that (400–450°F) during normal use. When overheated, these coatings can release invisible chemical fumes and microscopic particles that end up in your food or the air you breathe. Scientists published a study in eBioMedicine last year. They discovered that exposure to microplastics, especially PTFE, can cause lower sperm quality and male fertility.

Another concerning compound is PFOA, previously used in manufacturing nonstick coatings. While most U.S. brands phased it out by 2015 due to its link to cancer and hormone disruption, it’s still found in some imported or cheaper models.

Even products labeled “PFOA-free” or “non-toxic” can be misleading. They may contain newer PFAS substitutes like GenX or PFBS—chemicals with similarly worrisome health effects that aren’t as tightly regulated. PFOS, another PFAS chemical, was banned in many countries but still shows up in older or discounted appliances.

Unless your non-toxic glass air fryer specifically says “PFAS-free” and Prop 65-compliant (a strict California safety standard), it could still expose your family to toxic chemicals, especially when cooking at high heat.

The Health Risks of Air Fryers With Non-Stick Coatings 

Mounting scientific evidence shows that these substances accumulate over time, contributing to a range of serious health concerns. The International Agency for Research on Cancer (IARC) classifies PFOA as “possibly carcinogenic to humans”. The reports clearly show that elevated levels of PFAS in blood can cause kidney and testicular cancers. According to a new Science of The Total Environment study, one single scratch on a non-stick released 9,100 chemicals! PFAS exposure can interfere with endocrine function, affecting thyroid regulation and reproductive hormones, especially in women. One longitudinal study found that PFAS can reduce fertility and even delay puberty onset.

If that wasn’t enough, a 2020 study by the National Toxicology Program (NTP) confirmed that PFAS suppresses antibody production, potentially reducing vaccine efficacy and immune response in both adults and children.

A new research paper published in Nature Microbiology on July 1st, 2025, has found that certain human gut bacteria can absorb and store PFAS chemicals, potentially reducing their harmful effects on our health. Researchers suggest that boosting these bacteria in the gut could offer a natural way to defend against PFAS exposure.

Last month, a study published in the Journal of the American Heart Association linked prenatal PFAS exposure to a higher risk of elevated blood pressure that may cause cardiovascular issues later in life in children and teens. Researchers tracked over 1,000 children for 12 years and found stronger effects in adolescents, especially among males and Black children.

If you’re trying to avoid exposure to harmful chemicals, skip the confusing labels and go for a non-toxic glass air fryer without PTFE or PFOA. Models like a glass air fryer convection oven or a non-toxic air fryer glass bowl setup don’t rely on synthetic coatings. That means no fumes, no flakes, no “forever chemicals.”

Most experts recommend we find the best glass air fryer no Teflon.

What Is the Proposition 65 Warning On My Air Fryer?

California’s Proposition 65—formally called the Safe Drinking Water and Toxic Enforcement Act of 1986—requires businesses to provide warnings if their products expose consumers to any of over 900 chemicals known to cause cancer, birth defects, or reproductive harm. Everything from blenders and electric kettles to dumbbells can come with a warning!

Prop 65 warnings are often triggered by the presence of:

• Lead in electrical components or solder.
• BPA in plastics
• Flame retardants in wiring insulation
• PFAS in nonstick coatings

If an air fryer includes any of these, especially in parts that come into contact with food or heat—it may require a Prop 65 label. This is why it’s important to look for a BPA-free and PFAS-free air fryer in 2025 that doesn’t require a Prop 65 warning at all.

What Is An AB 1200 Warning?  

AB 1200, also known as California’s Cookware Right to Know Act, went into effect in January 2023. It requires cookware manufacturers to disclose if their products contain certain harmful chemicals, particularly those in the PFAS family, on any food-contact surface.

Under AB 1200, if an air fryer (or pan, pot, or utensil) contains chemicals like:

• PTFE (aka Teflon)
• PFOA or PFOS
• BPA
• Phthalates
• Heavy metals (e.g., lead, cadmium)

…manufacturers must clearly list those substances on the packaging or their website.

So if you’re shopping for a non-toxic glass air fryer PFAS free in 2025, look for brands that are AB 1200–compliant and openly disclose all materials used in their cookware.

Why Glass Air Fryers Without PTFE or PFOA Are the Safest Choice in 2025

In 2025, the safest air fryers are made with glass, stainless steel, or uncoated ceramic—but among these, glass stands out for both performance and peace of mind. Unlike metal or coated surfaces, glass is chemically inert, which means it won’t leach harmful substances, react with acidic foods like tomatoes or citrus, or trap odors over time. If you’re trying to avoid toxins like PTFE (Teflon) or PFOA, a glass air fryer eliminates the guesswork—no coatings, no risk.

And if you’ve ever wished you could actually see what’s happening inside your air fryer, glass gives you that advantage. Whether you’re crisping up cauliflower bites or watching a rotisserie chicken spin, the transparent cooking bowl lets you monitor browning, bubbling, and doneness without pausing the cycle or releasing heat. For visual cooks like myself—or anyone tired of burned fries—this is a game changer.

Cleaning is another win for glass. While traditional nonstick baskets scratch, flake, and absorb residue over time, borosilicate or tempered glass bowls rinse clean with minimal effort. They don’t stain or hold onto greasy smells, and many models are fully dishwasher safe. Some even come with self-cleaning steam cycles, which use high heat to melt away baked-on residue. You don’t have to baby them or worry about scrubbing delicate surfaces. Sadly, I was only able to find one truly safe, PFAS-free self-cleaning glass air fryer model.

And unlike coated models, you never have to wonder if something invisible is chipping off into your food. What you see is what you get, which is exactly why glass air fryers have become the go-to for people serious about non-toxic cooking in 2025.

7 Best Non-Toxic Glass Air Fryers Without PFAS and Teflon in 2025

1. Big Boss Large Glass Air Fryer Oven

Overall best non-toxic glass air fryer

• Capacity: 16 quarts 
• Settings: Air Fry, Bake, Grill, Roast & Toast 
• Features: Time & temperature knobs with 360° air convection  
• Wattage: 1300 watts
• Heat Range:  180℉ – 400℉
• Included Accessories: Mesh basket, high cooking rack, low cooking rack, glass bowl base

My Personal Review of Big Boss

Big Boss is by far the best non-toxic glass air fryer without PFAS in 2025! If you’re looking for a massive air fryer that can handle just about anything you throw at it, the Big Boss is all you need. I’ve been using this model for over six months. What makes the Big Boss stand out is its sheer size: the base unit comes with a 16-quart glass bowl, and with the extender ring, I am able to bump that up by an extra 5 quarts. That’s more than enough space to cook an entire chicken, a rack of ribs, or even dinner for 5 or 6 people when I have family over.

And because of the dual stainless steel racks, I can cook multiple foods at once—like veggies on the bottom and a seasoned steak or roast on top.

Performance-wise, the 1300W fan and 360° convection system deliver quick, even heating that outperformed several smaller air fryers I’ve tested. Chicken wings, fish, and even baked potatoes came out beautifully crisp on the outside and tender inside. I love how you can watch everything cook in real time, thanks to the glass bowl. Just adjust the dials as needed if you spot something browning too quickly.

The controls are basic but effective—just two dials (time and temperature), and once you get a feel for the heat curve, it’s easy to tweak on the fly. The built-in safety shut-off when lifting the handle is a smart touch, and I’ve used it more than once to quickly stop the machine when I noticed food was ready before the timer.

Another feature I appreciate is how the fryer bowl keeps food separated from excess fat. It’s ideal for anyone wanting to eat cleaner without sacrificing that deliciously crisp texture. Clean-up is also pretty painless: the glass bowl is dishwasher-safe, and I usually just give the lid and fan housing a wipe-down (since it’s not submersible).

This thing is heavy, though. The bowl on this glass air fryer without Teflon is thick and weighty, and the motorized lid is permanently attached, which can make cleaning a bit awkward. I wish the lid detached for better access, but the built-in handle is well-balanced, so it still feels manageable. Just don’t expect to casually lift it in and out of the cabinet with one hand.

❌ Cons:

• The glass bowl is very heavy, and the unit overall is quite bulky
• The lid is non-detachable, which makes it trickier to clean
• No digital controls or presets—just two simple dials
• This glass air fryer without PTFE or PFOA takes  up a lot of counter or cupboard space, so not ideal for small kitchens

2. BOSWELL Glass Air Fryer

Best non-toxic glass air fryer for 2 people

• Capacity: 4.5 quarts 
• Settings: Bake, Broil, Air Fry
• Features: Temperature Control, Timer
• Wattage: 1200 watts
• Heat Range:  60- 400°F 
• Included Accessories: Silicone pad, gloves, tweezers

My Personal Review of Big Boss

Right after Big Boss, this is the second-best non-toxic glass air fryer without PTFE or PFOA in 2025. I really don’t understand why there isn’t much hype around BOSWELL. Right off the bat, the transparent glass body makes this air fryer stand out. For more, watching your food crisp up in real time is both practical and oddly satisfying. There is no need to open the lid or lose heat. I always just glance through the glass to monitor doneness. It’s especially helpful if you’re cooking something delicate or trying not to overdo it.

This PFAS-free air fryer features five one-touch presets (chicken, steak, fries, baked goods, seafood), so it’s very user-friendly right out of the box. I tested it head-to-head against my small convection oven, roasting chicken wings at 400°F in both. No contest. The BOSWELL delivered wings with perfectly golden, crunchy skin, while the oven left them pale and underwhelming. That 360° hot air circulation system really does the job.

It also heats up fast. I was impressed by how quickly it reached temp, and unlike some models I’ve used, the BOSWELL lets you manually adjust the temperature and time—up to 400°F and 60 minutes—so you can really dial things in for anything from slow-roasted veggies to flash-fried tofu cubes.

Cleanup is easy, too. The glass bowl and basket are non-toxic and have a special coating that resists sticking. Just a quick rinse right after cooking kept things spotless. Bonus points for the included silicone mat, clamps, gloves, and recipe guide—all thoughtful touches that make the cooking process smoother and safer.

In short, if you’re looking for a compact, non-toxic glass air fryer without Teflon that consistently delivers crisp results without guesswork, this one is hard to beat.  

❌ Cons:

• Capacity is smaller—best for solo cooks or small portions.
• No digital display, just simple button controls
• You’ll want to rinse the grate quickly to avoid buildup

3. Ninja Crispi Glass Air Fryer

PFAS-free glass air fryer with the most programs

• Capacity: 4-qt & 6-cup glass containers
• Settings: Air Fry, Bake, Reheat, Max Crisp, Air Roast, Air Broil, Dehydrate 
• Features: Temperature Control, Timer, Automatic Shut-Off, Programmable
• Wattage: 1500 watts
• Heat Range: 22°F–450°F 
• Included Accessories: TempWare glass containers and 2 storage lids 

My Personal Review of Ninja Crispy

The Ninja Crispi All-in-One System is a truly unique find—and an easy favorite for portable, PFAS-free cooking. It’s a cleverly designed system that gives you multiple container sizes, the real glass you can see through while cooking, and a surprisingly compact base unit called the Crispi PowerPod.

Instead of the typical black plastic basket, you get high-grade borosilicate glass containers—one 6-cup for small meals and one 4-quart for family dinners. I absolutely loved being able to see my food crisp up without lifting the lid. That transparency added a whole new layer to my air frying. And just like Big Boss and BOSWELL, it also made it easier to know exactly when something was done.

What really impressed me was the easy storage system. Air fryers tend to be super bulky for my small countertops. But everything inside Ninja Crispi stacks and nests together, so it doesn’t take over my kitchen. Cleanup was a breeze since the containers, crisper plates, and adapters are all dishwasher safe. I’m someone who air fries several times a week, and this was hands down the easiest-to-clean air fryer I’ve ever used.

As far as performance, it did everything I wanted: perfectly crispy fries, tender roasted veggies, cheesy little pizzas, even grilled sandwiches. The ceramic-coated crisper plates reassured me that I wasn’t exposing my family to PFAS or mystery coatings. And since it only uses 1000 watts, I’m already planning to take it along in the RV for low-power cooking on the road.

Plus, this non-toxic glass air fryer comes with leak-proof lids for both containers, so I can go straight from cooking to storing leftovers without needing to transfer dishes. The adapter ring for the Crispi Pod makes it super easy to switch between the small and large bowls, and I loved how intuitive the whole system felt.

❌ Cons:

• At nearly 16 lbs, it’s marketed as portable, but it’s honestly a bit heavy to carry around often.
• The 4-quart capacity may not cut it for bigger families or entertaining.
• It lacks manual temperature control, and the preset modes are fewer than most full-size air fryers.
• On the pricier side (just under $200), it may not be ideal if you’re looking for a budget model.

4. Fritaire Glass Air Fryer With Rotisserie

Best self-cleaning glass air fryer without Teflon

• Capacity: 5 quarts 
• Settings: Air Fry, bake, roast, broil, reheat, or dehydrate
• Features: Self-Cleaning Mode, Rotisserie Capability, 6-IN-1 Single Touch 
• Wattage: 1500 watts
• Heat Range:  Up to 400°F 
• Included Accessories: Rotisserie skewer, rack, and tumbler

My Personal Review of Fritaire

The Fritaire Air Fryer is one of the most display-worthy non-toxic glass air fryers with rotisserie I’ve tested. Again, as someone who prefers non-toxic cookware and loves seeing my food as it cooks, the ability to monitor everything without opening the lid was a big plus. 

Fritaire promises a self-cleaning function, and I was honestly skeptical—but it works. I followed the instructions and added a bit of dish soap and water, hit the clean mode, and let it go. That said, I didn’t even need it most of the time. The glass bowl was simple to wipe down, and most food residues came off easily unless I used the rotisserie basket to cook my veggies and fish (more on that in a second). The bowl and lid inserts are all dishwasher safe, and I appreciated that convenience.

Cooking-wise, the 1500-watt convection power and 400°F vortex heat delivered some of the crispiest results I’ve had. Especially for homemade fries and breaded cauliflower. The temperature control dial gives me more precision than the Ninja Crispi, which was a welcome bonus. I cooked everything from roasted veggies to juicy chicken breasts, and it always felt intuitive and evenly heated.

This PFAS-free air fryer comes with 6-in-1 functions, and I tested most of them: bake, air fry, roast, reheat—you name it. The rotisserie feature is what initially drew me in, but here’s where I ran into some snags. The motor only turns at one speed, and I noticed that delicate crisped bits would fall off my food mid-rotation. Worse, unloading the basket while it was still hot (400°F) required a lot of awkward maneuvering—definitely not ideal if you’re impatient or juggling a busy dinner prep.

In terms of materials, the Fritaire’s non-toxic air fryer glass bowl is, BPA-free, and Teflon-free.  The accessories are mostly dishwasher safe except for the rotisserie basket, which needs to be hand-washed carefully. After making wings once, I had to scrub for a while—lesson learned.

Design-wise, it is a non-toxic air fryer glass bowl, and it does get hot on the outside. So you have to be mindful when lifting or moving it. Thankfully, the lid turns off the heat automatically when lifted, which I found to be both safe and convenient if you want to toss in extra ingredients partway through cooking.

❌ Cons:

• Rotisserie basket can be a hassle—too fast, and tough to open safely when hot.
• The glass bowl is heavy and gets hot to the touch during use.
• Metal accessories aren’t dishwasher safe and can be tricky to clean, especially after oily foods.
• Takes up a good amount of counter space

5. APSARAS Pro 8in1 Glass Air Fryer

Best for large families

• Capacity: 18 quarts 
• Settings: Cook, Bake, Grill, Steam, Broil, Roast & Air-Fry
• Features: Temperature Control, Shut-off, Timer, Stain Resistant, Programmable 
• Wattage: 1200 watts
• Heat Range:  Up to 480°F 
• Included Accessories: High rack, low rack, extended ring, tongs, holder, baking sheet, forks, grill 

My Personal Review of APSARAS

If you need an even larger non-toxic glass air fryer than Big Boss, look no further than Flying Apsaras. At first glance, it checked a lot of boxes—borosilicate glass, 304 stainless steel, BPA-free plastic, tons of accessories, and a gigantic 18-quart capacity. 

This unit is undeniably spacious. With the expansion ring in place, you could roast a small turkey in it. It’s great for batch cooking or family meals, and I appreciated being able to cook a few different dishes at once using the included short and tall wire racks, skewers, and mesh trays. I made some egg bites with parchment underneath (at 180°C for 9 minutes), and they came out surprisingly perfect—moist, fluffy, and evenly cooked.

The watch-your-food glass bowl is fun to use and helps reduce overcooking since you can check on things without guessing. The safety shut-off when lifting the lid is a thoughtful feature—just pop the lid off, check your food, and it starts right back up when the lid is replaced.

There’s also a wash cycle, although I found it easier to just use parchment or give the bowl a rinse. With all the included accessories—skewers, lid holder, expansion ring, racks, tray, tongs—it feels like a full oven kit.  

On another note, I was also disappointed by the total lack of instructions or recipes. YouTube helped, but if you’re new to these kinds of appliances, the learning curve will be steeper than it should be.

Another quirk: the PFAS-free air fryer makes a noticeable clicking sound every time the heat cycles on and off, which can get annoying fast. And while it’s not overly loud otherwise, that constant clicking pulls your attention—especially in a quiet kitchen.

❌ Cons:

• Heats slowly, sometimes slower than a regular oven
• Annoying clicking noise as the unit cycles on/off

6. Nutrichef Glass Air Fryer Convection Oven

Best non-toxic glass air fryer convection oven

• Capacity: 18 quarts 
• Settings: Cook, Bake, Grill, Steam, Broil, Roast & Air-Fry
• Features: Temperature Control, Shut-off, Timer, Stain Resistant, Programmable 
• Wattage: 1200 watts
• Heat Range:  Up to 480°F 
• Included Accessories: High rack, low rack, extended ring, tongs, ID holder, baking sheet, forks, grill 

My Personal Review of NutriChef

If you’ve ever wished your oven cooked faster, healthier, and cleaner, then you’re going to like what the NutriChef Glass Convection Oven brings to the table. This is NutriChef’s appliance, in my opinion. It holds up to 18 quarts of food in a wide glass bowl—perfect for prepping family-sized meals without heating the whole kitchen.

Despite the large capacity, the NutriChef is still countertop-friendly. Even for my small apartment, it didn’t take much space on the coutnertop. I found the setup refreshingly simple: just rotary dials for time and temperature, two wire racks, and a set of tongs for easy serving. The clear glass body is a nice bonus—you can watch your food cook without having to open the lid and lose heat.

Performance-wise, this cooker really shines. I roasted a batch of organic chicken drumsticks at 480°F for about 55 minutes, flipping them halfway. The result? Super crispy skin with golden, bubbling fat collecting at the bottom. The high heat paired with that built-in convection fan makes a huge difference—it circulates hot air evenly and cooks way faster than my regular oven.

I also threw in some asparagus spears marinated in a vinegar dressing, and they came out tender-crisp and full of flavor. Whether it’s meats, veggies, or even baked goods, this thing doesn’t just cook—it locks in juices and enhances flavor.

Health-wise, this is a truly non-toxic glass air fryer without PTFE or PFOA. The unit uses little to no oil thanks to its air-fry capabilities. It’s versatile enough to handle baking, broiling, grilling, roasting, steaming, and air frying. You really don’t need multiple kitchen gadgets when this one does it all.

That said, I did notice the seal between the lid and bowl could be a little tighter—not a dealbreaker, but something to keep in mind if you’re trying to retain every bit of heat. Still, I appreciated the lack of blinding lights and the quiet electric coil system that gets the job done efficiently. 

❌ Cons:

• The seal between the lid and bowl could be tighter.
• Analog dials might feel a bit dated to some
• No digital display or preset programs
• Almost always sold out

7. Midea Flexify Toaster Oven Air Fryer Combo

• Capacity: 26.4 quarts 
• Settings: Air Fry, Roast, Bake, Broil, Toast, Pizza, Reheat, Slow Cook, Dehydrate, and Warm 
• Features: Temperature control, VDE-certified heat evenness, Programmable, LED display 
• Wattage: 1750 Watts
• Heat Range: 100°F to 450°F
• Included Accessories: Roaster oven, baking tray, two baking racks, air fry basket, crumb tray

My Personal Review of Midea:

If you’re looking for a spacious, PFAS-free air fryer toaster oven that looks as good as it performs, the Midea Flexify is a fantastic choice. I’ve been testing this unit over the past several months, and it’s clear this model punches above its weight in value, versatility, and non-toxic performance.

What immediately stood out to me was the design. The French doors open smoothly with one hand, giving me easy access to a surprisingly roomy interior. At just over 16 inches wide, it fits comfortably under most cabinets, but inside it’s big enough to roast a full chicken, bake a 12-inch pizza, or layer multiple foods at once. The stainless steel air fryer interior and accessories are thoughtfully designed for durability and easy cleaning—plus, the brand confirmed with me directly that this model is completely free from PFAS, PFOA, and PTFE.  

The 10 cooking functions cover everything from air frying and baking to dehydrating and reheating. I’ve personally made steaks, lasagna, garlic bread, brownies, burgers, toast, and even lobster in this machine—and the results have consistently impressed me. The heat-up time is fast, and the 1800-watt power ensures crisp edges and juicy centers. One function I especially love is pizza: the crust turns golden without burning, and the cheese melts perfectly.

Controls are intuitive: the digital screen is easy to read, and adjusting time and temperature is straightforward. You get multiple cooking levels, and the Flexify comes with a wire rack, air fryer basket, and baking sheet, so you’re covered whether you’re crisping fries or roasting veggies.

Now for the downsides: The air fryer basket is smaller than you might expect for the oven’s overall size, so I found myself using the wire tray more often for bigger batches. And while the stainless steel housing looks great, it does get quite hot during extended use, so you’ll want to make sure there’s plenty of airflow around it. 

Overall, this is one of the best non-toxic air fryers toasted over combos that replaces several countertop gadgets in one sleek design. It’s especially great for families, batch cookers, and anyone trying to streamline their kitchen while avoiding PFAS-laced nonstick coatings.

❌ Cons:

• The air fryer basket is on the smaller side
• The toasting function doesn’t quite match a traditional toaster
• The exterior gets hot during use
• A bit noisy when the fan is running

PFAS-Free Glass Air Fryers I Don’t Recommend

• Gourmia GTF7520 Toast Oven Air Fryer: Similar to the GTF7460, this model comes with an aluminum baking tray, which has raised concerns among users about its non-toxic claims.
• GE Digital Air Fry 8-in-1 Toaster Oven: Although the brand disclosed that there are no PFAS, PTFE, PFOA, or BPA in the oven or its accessories, some users have reported concerns about the materials used in the baking trays and racks, suggesting a need for caution.

How to Choose the Best Glass Air Fryer Without Teflon for Your Needs

• Prioritize Non-Toxic Materials: Look for air fryers labeled PFAS-free, PTFE- and PFOA-free, and BPA-free. Check if the brand discloses materials under California AB 1200 for extra transparency.
• Match the Size to Your Household: For solo or couple cooking, 2–4 quart models are ideal. For families or meal prep, go for a larger glass air fryer with rotisserie or multi-rack features.
• Evaluate Cooking Performance: Choose models with a wide temperature range, fast preheat, and even heat distribution. Reviews that mention crisp results and consistent browning are a good sign.
• Check for Easy Cleaning Features: Choose units with glass bowls, removable parts, or even self-cleaning options. Avoid models with tricky crevices or coatings that can wear off.
• Look for Intuitive Controls: Digital touchscreens, useful presets, and a simple user interface make a big difference—especially if you’re new to air frying.
• Don’t Skip the Warranty: A solid warranty and responsive customer support are essential for peace of mind. It also signals the manufacturer stands behind its product.
• Beware of Greenwashing: Claims like “PFOA-free” don’t always mean Teflon-free air fryer. Always read the fine print and verify materials if health is your top priority.

How to Clean and Care for Your Glass Air Fryer 

Caring for your glass air fryer without PTFE or PFOA properly not only keeps it performing at its best—it also protects the integrity of the materials and ensures it stays a safe, toxin-free part of your kitchen.

• Always let it cool completely before cleaning. Rapid temperature changes can cause thermal shock in glass components, increasing the risk of cracking.
• Avoid abrasive scrubbers. Use a soft, plastic-free sponge or cloth with non-toxic dish soap to prevent scratches on the glass bowl or surface.
• Check if it’s dishwasher-safe. Many non-toxic glass air fryer bowls are top-rack safe, but always confirm with the manual to avoid warping or seal damage.
• Clean food residue right away. Burnt bits left on racks or trays can be harder to remove and may damage non-coated surfaces over time.
• Don’t use metal utensils. To preserve both the glass and any included accessories, stick with silicone, wood kitchen utensils.
• Inspect for cracks or chips regularly. Even minor damage to the glass can compromise safety during high-heat use—replace parts if needed.
• Store it safely. If you disassemble your unit for storage, make sure the glass bowl is cushioned and protected from hard knocks or falls.

More Brands With Non-Toxic Kitchen Appliances 

• Our Place: I’ve tested the Our Place ceramic pressure cooker, the Always Pan, and the PFA-free stainless steel air fryer oven. Their designs are absolutely stunning. But most importantly, this non-toxic company is very transparent with its materials and certifications.
• GreenPan: I have used GreenPan’s non-toxic panini press and PFAS-free ceramic nonstick cookware pretty much on a weekly basis since last December. This company pioneered the first PFAS-free ceramic nonstick cookware using their patented Thermolon™ coating made from sand derivatives.

Final Thoughts on the Best Non-Toxic Glass Air Fryers Free of PFAS, PTFE, & PFOA

There you have it, my top picks for glass air fryers without PTFE or PFOA, tested in my kitchen. When it comes to choosing a safe air fryer, the material matters. The worst options you should absolutely avoid are nonstick baskets coated with Teflon (PTFE) or other PFAS-based chemicals, which can release toxic fumes and degrade over time, especially under high heat. Instead, look for PFAS-free glass air fryers made with borosilicate glass, 304 stainless steel, and ceramic-coated or bare metal baskets free from synthetic coatings. These materials are durable, non-toxic, and heat-safe, making them a smarter, safer choice for daily cooking. Remember that beyond materials, key features to look for include adjustable temperature controls, a glass or see-through cooking bowl so you can monitor food safely, a stainless steel heating element, and easy-to-clean parts without hidden coatings.
