Best Non-Toxic Air Fryers: Glass, Ceramic & Stainless Steel Picks

If you’re searching for the best non toxic air fryer, the first thing to decide is what you actually want to avoid.

Some shoppers want no PTFE where food cooks. Others want a clearly documented PFAS-free ceramic coating. Some would rather use glass or bare stainless steel even if that means giving up some of the easy-release benefits of a coated basket.

There isn’t one universal certification called a “non-toxic air fryer,” so this guide uses something more useful: documented food-contact materials.

The models below were selected because their manufacturers currently identify food-contact surfaces such as glass, steel, or ceramic coatings described as PFAS- or PTFE-free.

Manufacturer specifications checked: September 29, 2026.

This is a specification-based comparison, not a Fryer Bites hands-on test. Material, capacity, temperature, and feature claims are attributed to the manufacturers.

Also, choosing a PFAS-free model does not mean every conventional PTFE air fryer is automatically unsafe. If that’s the question you’re trying to answer first, see what the evidence says about air fryer toxicity.

Best Non-Toxic Air Fryers at a Glance

The right choice depends less on a single “best” model and more on whether you prioritize glass, an uncoated steel design, easy-release ceramic, capacity, or cooking surface area.

What Does “Non-Toxic Air Fryer” Mean Here?

“Non-toxic” is a popular shopping term, but it doesn’t identify one specific material or regulatory standard.

For this guide, a model needs a manufacturer-documented food-contact design that includes at least one of the following:

• explicitly PFAS-free cooking surfaces
• explicitly PTFE-free cooking surfaces
• glass cooking vessels
• bare stainless-steel or steel food-contact surfaces
• ceramic coatings specifically described as PFAS-free

That is more useful than marketing phrases such as:

• healthy coating
• green coating
• eco coating
• natural nonstick
• safer coating

The wording also needs to apply to the parts that actually contact food.

A stainless-steel exterior doesn’t tell you what the basket is made from. Likewise, a glass cooking bowl doesn’t necessarily mean every removable crisper plate inside it is bare glass or steel.

Glass vs. PFAS-Free Ceramic vs. Stainless Steel

Before comparing individual air fryers, it helps to choose the material approach that fits your priorities.

Glass

Glass gives you one of the clearest food-contact materials to understand.

It can also let you see food while it cooks.

But don’t assume a product marketed as a “glass air fryer” is made entirely from glass. Some systems pair a glass vessel with a separate coated crisper plate.

Glass can also be:

• heavier than a standard drawer
• more awkward to move with one hand
• breakable if dropped or exposed to inappropriate handling

PFAS-free ceramic

Ceramic-coated baskets feel more familiar if you’re used to a traditional pull-out air fryer.

They usually offer easier food release than bare steel while avoiding PTFE when the manufacturer explicitly documents the coating as PFAS- or PTFE-free.

But ceramic is still a coating.

It should be protected from:

• metal utensils
• abrasive pads
• aggressive scraping
• cleaning methods the manufacturer doesn’t recommend

Stainless steel and steel

Bare steel avoids the need for a conventional nonstick coating on that specific food-contact surface.

It also tends to be durable.

The tradeoff is that food can stick more easily, especially with lean or starchy foods.

Steel is especially common in oven-style air fryers, where the basket may resemble a wire mesh tray rather than a deep drawer.

If you’re deciding between those appliance styles, our basket vs. oven-style air fryer guide explains the practical differences.

1. Ninja Crispi Pro — Larger Glass-System Option

The Ninja Crispi Pro is one of the more interesting current choices for shoppers who specifically want a glass cooking system but need more room than the original Crispi.

Food-contact design

The system combines:

• borosilicate glass cooking containers
• nano-ceramic-coated aluminum crisper plates

SharkNinja says the food-contact surfaces are designed without PFAS and PTFE.

That’s an important distinction.

The food isn’t necessarily sitting directly on bare glass for every cooking task. When the crisper plate is used, food can contact the nano-ceramic-coated aluminum plate.

Key specifications

• 6-quart glass container
• 2.5-quart glass container
• 1,800 watts
• up to 450°F
• six cooking functions
• adjustable temperature
• transparent cooking vessel

Why the design stands out

The larger glass container gives the Crispi Pro more family-meal flexibility than the original compact system.

You also get the visibility advantage of glass without switching to a round bowl-style appliance.

The smaller container is useful when you’re reheating leftovers or making a smaller portion and don’t need the full six-quart vessel.

Main considerations

Glass is heavier than a conventional metal drawer.

You may also prefer using two hands when moving a hot glass container instead of pulling out a basket by one handle.

And while the main vessels are glass, the crisper plates remain separate coated components.

Original Ninja Crispi vs. Crispi Pro

The original Ninja Crispi still makes sense if compact size and portability matter more than capacity.

The Crispi Pro is the stronger fit when you want:

• more cooking space
• adjustable temperature
• additional cooking modes
• a more conventional countertop-air-fryer role

Neither should be described simply as “all-glass cooking.”

2. COSORI Iconic 6.5-Quart — Traditional Smart Ceramic Basket

If you like the familiar pull-out air fryer design but want explicitly documented PFAS-free ceramic food-contact surfaces, the COSORI Iconic 6.5-Quart takes a different approach from the glass models.

Food-contact design

COSORI currently describes its ceramic-coated cooking surfaces as free from:

• PFAS
• PTFE
• BPA

The appliance also uses a stainless-steel structure.

Key specifications

• 6.5-quart capacity
• ceramic-coated basket and crisper plate
• 90°F–450°F range
• five fan speeds
• smart connectivity
• five-year limited warranty

Why the design stands out

You don’t have to adapt to a glass bowl or oven rack.

The Iconic keeps the conventional basket format many air fryer users already understand.

The multiple fan speeds also give the appliance more airflow control than basic single-speed models.

Main considerations

The food still cooks on a coated surface.

If you specifically want no coating at all where food sits, glass or bare steel will make more sense.

Ceramic also needs careful cleaning to protect the cooking surface.

3. Typhur Dome 2 — Wide, Shallow Ceramic Basket

The Typhur Dome 2 is different from most air fryers because it prioritizes usable horizontal area instead of a tall, deep drawer.

Key specifications

Typhur currently lists:

• 5.6-quart capacity
• PFAS-free ceramic coating
• approximately 139.5 square inches of cooking area
• room for up to a 12-inch pizza
• roughly 2.3-inch basket height
• 105°F–450°F temperature range
• top and bottom heating
• approximately 19.7 × 15.6-inch countertop footprint

Some app and fan-control features vary between the AF03 and AF05 versions, so check the exact model number before buying.

Why surface area matters

A five- or six-quart air fryer isn’t automatically small just because another model says eight quarts.

Foods such as:

• wings
• bacon
• steaks
• burgers
• vegetables
• pizza

often benefit from being spread in a single layer.

A wide basket can therefore be more useful than a deeper basket with a larger volume number.

Main considerations

The Dome 2 takes up significant countertop space.

Its shallow cooking chamber can also be less convenient for tall foods.

It’s a particularly good design to compare by dimensions and usable area, not just quarts.

If you’re unsure how capacity numbers translate into real cooking space, see our guide to choosing the right air fryer size.

4. Our Place Wonder Oven Pro — Steel Oven-Style Option

The Our Place Wonder Oven Pro is the most different appliance in this group because it’s an oven-style air fryer rather than a pull-out basket.

It’s also important not to confuse the current Wonder Oven Pro with the smaller standard Wonder Oven.

Current Wonder Oven Pro specifications

The Pro is currently listed with:

• 28-liter capacity
• eight cooking functions
• 80°F–450°F temperature range
• stainless-steel and glass interior
• large steel air fryer basket
• steel wire rack
• steel crumb tray
• aluminum bake pan with ceramic coating

Our Place states that its included interior accessories are made without:

• PFAS
• PTFE
• PFOA
• lead
• cadmium

The company also reports third-party materials testing performed in 2026. That is a manufacturer-provided testing claim, not testing performed by Fryer Bites.

Why the design stands out

The main air-frying basket and racks are steel rather than a conventional coated pull-out drawer.

The oven format also works better for foods that benefit from:

• broad racks
• toast
• baking
• larger flat items
• multi-purpose oven use

Main considerations

The Wonder Oven Pro is much larger than a typical basket air fryer.

If your main goal is reheating fries or making one portion of chicken, you may not need a 28-liter countertop oven.

Also remember that not every accessory is bare steel: the included bake pan uses a ceramic coating.

5. GreenLife EZ 4.5-Quart — Simple Ceramic Basket

Not everyone needs Wi-Fi, app controls, several fan speeds, or a large touchscreen.

The GreenLife 4.5-Quart EZ Air Fryer keeps the design straightforward.

Food-contact materials

GreenLife says the ceramic nonstick used on the drawer and tray is made without:

• PFAS
• PFOA
• lead
• cadmium

Key features

• 4.5-quart capacity
• ceramic-coated drawer
• ceramic-coated tray
• manual time and temperature controls
• stay-cool handle
• dishwasher-safe removable drawer and tray

Why the design stands out

The appeal is simplicity.

You get a conventional basket-style air fryer with an explicitly documented PFAS-free ceramic cooking surface without paying for features you may never use.

Main considerations

This is a more basic appliance than the COSORI Iconic or Typhur Dome 2.

If you specifically want:

• app control
• advanced airflow adjustment
• many cooking functions
• a very wide basket

another model will fit better.

6. Fritaire 5-Quart — Glass Bowl With Stainless Accessories

The Fritaire 5-Quart Glass Air Fryer takes the glass concept in a completely different direction from the Ninja Crispi systems.

Instead of a rectangular glass container, it uses a large transparent glass bowl.

Food-contact materials

Fritaire currently describes:

• tempered-glass cooking bowl
• 304 stainless-steel accessories
• no food-contact coating
• PFAS-free food-contact surfaces
• PTFE/Teflon-free food-contact surfaces
• BPA-free food-contact surfaces

Current features

The current version is listed with:

• 5-quart capacity
• nine cooking functions
• 90°F–400°F range
• rotisserie
• tumbling basket
• bake
• roast
• toast
• dehydrate
• self-cleaning function

Why the design stands out

The transparent bowl makes the cooking process easy to see.

The rotating tumbler is also unusual among glass air fryers and may appeal if you frequently cook foods such as:

• fries
• vegetables
• smaller roasted pieces

The stainless accessories also give this product a distinctly different food-contact setup from ceramic drawer models.

Main considerations

The round glass design is less familiar than a normal drawer basket.

It’s also not especially compact.

One specification worth noticing is the manufacturer’s relatively short 60-day warranty, which is much shorter than the warranty offered by some competing models.

That doesn’t tell you how long the appliance will last, but it is a practical purchasing difference worth checking before buying.

7. Bella PRO SmartCrisp 8-Quart — Large Ceramic Basket

The Bella PRO SmartCrisp 8-Quart is the large conventional basket option in this comparison.

Food-contact coating

Bella says its EverGood ceramic nonstick coating is made without:

• PFAS
• PTFE
• PFOA
• lead
• cadmium

Key specifications

• 8-quart capacity
• 1,700 watts
• 90°F–450°F temperature range
• Air Fry
• Broil
• Roast
• Bake
• Reheat
• Dehydrate
• shake reminder
• dishwasher-safe removable basket and crisper tray

Why the design stands out

Eight quarts gives you more basket volume than the smaller GreenLife and glass systems.

That can make sense for:

• families
• larger batches
• meal prep
• bigger portions

while retaining a conventional drawer design.

Main considerations

An 8-quart capacity doesn’t mean you should fill the basket to the top when crispness matters.

Air still needs room to circulate around the food.

It’s also a single large basket rather than a dual-zone system, so you can’t independently run two different time and temperature settings at once.

Also Consider: Nuwave Brio Plus 7-Quart

The Nuwave Brio Plus 7-Quart is another current option worth checking if you want a family-size ceramic basket.

Nuwave currently lists:

• 7-quart capacity
• all-metal interior
• PFAS-free ceramic basket
• 50°F–400°F temperature range
• adjustable power up to 1,800 watts

It doesn’t need a full eighth slot in this guide, but it’s a reasonable alternative if the main seven don’t match your preferred size or design.

What Actually Touches Your Food?

This is the question I would check before relying on any “glass,” “ceramic,” or “stainless steel” headline.

This is also why exterior materials aren’t enough.

A product can have a stainless-steel shell and still cook food in a coated aluminum basket.

Likewise, a product with a plastic exterior may have glass or metal where the food actually sits.

If you’d like to understand why basket shape and airflow matter once you’ve chosen the material, see how air-fryer airflow works.

Which Size and Shape Should You Buy?

Don’t choose an air fryer based only on the quart number.

Compact glass systems

Best suited to:

• smaller portions
• reheating
• couples
• limited meal sizes
• people who want to cook and store food in the same glass vessel

The original Ninja Crispi fits this role better than the larger Crispi Pro.

Traditional 4–7 quart baskets

These are the most familiar general-purpose format.

Examples in this guide include:

• GreenLife EZ
• COSORI Iconic
• Nuwave Brio Plus

They work well for everyday meals without requiring oven-size counter space.

Wide, shallow baskets

The Typhur Dome 2 is the clearest example.

Instead of emphasizing depth, it gives food more horizontal room.

That’s useful when a recipe needs a single layer.

Large 8-quart baskets

The Bella SmartCrisp gives you more overall basket volume, but remember that usable crisping area and total volume aren’t the same thing.

Oven-style designs

The Wonder Oven Pro offers racks and broader interior space.

It’s better suited to shoppers who want one appliance to handle:

• air frying
• baking
• toast
• larger flat foods
• oven-style cooking

The tradeoff is countertop space.

How to Protect a PFAS-Free Ceramic Coating

Choosing a ceramic coating doesn’t eliminate the need to care for it.

PFAS-free ceramic is still a surface layer that can wear or become damaged.

Use gentler utensils

When the manufacturer allows them, use:

• silicone utensils
• wooden utensils
• nonabrasive tools

Avoid repeatedly scraping the cooking surface with metal tools.

Clean without aggressive abrasion

Start with:

• warm water
• dish soap
• a soft sponge or cloth

rather than immediately reaching for harsh scrubbers.

For more detailed care, use our guide to cleaning a coated air fryer basket safely.

Don’t invent a lifespan

There isn’t one useful rule saying every ceramic coating lasts a specific number of months or years.

Durability can vary with:

• coating formulation
• cleaning
• utensils
• cooking frequency
• dishwasher use
• manufacturer design

The condition of your actual basket matters more than a generic lifespan claim.

Replace seriously deteriorated parts

If a cooking surface begins:

• peeling extensively
• blistering
• flaking repeatedly
• separating from the underlying material

follow the manufacturer’s replacement guidance.

Which Air Fryer Fits Your Priorities?

There isn’t one model here that is automatically right for every shopper.

Use your biggest priority to narrow the list.

These are matches based on documented features and materials, not a Fryer Bites performance ranking.

Before ordering, also check:

• exact model number
• current dimensions
• current warranty
• replacement-part availability
• electrical requirements
• whether every accessory you plan to use has the material you want

Manufacturers can change product generations and specifications, so the exact model matters.

Frequently Asked Questions

Is a glass air fryer completely coating-free?

Not always. The cooking vessel may be glass while another component is coated. For example, Ninja’s Crispi systems use glass containers with separate nano-ceramic-coated aluminum crisper plates.

Does ceramic automatically mean PFAS-free?

No. “Ceramic” alone isn’t enough. Look for an explicit manufacturer statement that the relevant cooking surfaces are PFAS-free or PTFE-free.

Does PFOA-free mean PFAS-free?

No. PFOA is only one member of the wider PFAS family. A PFOA-free product can still use PTFE.

Our guide to air fryer toxicity and PFAS concerns explains that terminology in more detail.

Are there air fryers with stainless-steel baskets?

Yes. Oven-style models are more likely to use steel air-fryer baskets or wire racks. However, inspect every included tray and baking pan separately because one accessory may use a coating even when the main basket is steel.

Is glass better than ceramic?

Neither is universally better.

Glass gives you an easily identified uncoated cooking vessel but is heavier and breakable.

PFAS-free ceramic gives you more traditional nonstick-style release but remains a coating that needs appropriate care.

Which type is easiest to clean?

That depends on the exact design, coating, dishwasher compatibility, and type of food you’re cooking. Without direct comparative testing, there isn’t a defensible universal winner.

Is the Ninja Crispi really PFAS-free?

SharkNinja says the Crispi food-contact surfaces are designed without PFAS and PTFE. That includes its glass containers and the nano-ceramic-coated aluminum crisper plates.

Should I buy the biggest air fryer I can afford?

Not necessarily. Basket shape and usable single-layer space can matter as much as total quart capacity. A wide smaller basket can be more useful for some foods than a deeper basket with a larger volume rating.

Final Takeaway

The most useful way to shop for a non-toxic air fryer is not to look for one magic label.

Start by deciding which material approach you actually prefer:

• glass if you want a clearly identifiable primary cooking vessel
• bare steel if durability and avoiding conventional basket coatings matter most
• documented PFAS-free ceramic if you still want the convenience of a nonstick-style drawer

Then check the parts that really touch your food.

A glass model may still have a ceramic-coated crisper plate. A steel oven may include a ceramic-coated bake pan. A ceramic air fryer is only meaningfully “PFAS-free” for this comparison when the manufacturer specifically says so.

For larger glass cooking, the Ninja Crispi Pro is the model to compare. For a traditional smart ceramic basket, look at the COSORI Iconic. For wide single-layer cooking, the Typhur Dome 2 takes a different approach. The Wonder Oven Pro makes more sense if you want steel oven-style air frying, while GreenLife, Fritaire, and Bella cover simpler ceramic, glass-bowl, and large-basket needs.

The final choice should come down to documented food-contact materials, usable cooking shape, capacity, counter space, and the features you will actually use—not a vague “non-toxic” sticker on the box.
