Does Cosori Air Fryer Have PFAS? | PFAS-Free Models

PFAS chemicals earned the nickname “forever chemicals” because they don’t break down easily in the environment or the human body. That reputation has made many home cooks wary of nonstick coatings, especially on appliances that reach high heat like air fryers. Cosori is a popular brand, and if you’re shopping for one, it’s reasonable to wonder whether its baskets are safe.

The good news is that Cosori has largely moved away from traditional PTFE-based nonstick coatings. The company now offers multiple models with ceramic or stainless steel cooking surfaces that are explicitly marketed as PFAS-free. Still, the answer depends on which model you choose and when it was made.

What PFAS Are and Why They Matter in Air Fryers

PFAS (per- and polyfluoroalkyl substances) are a broad group of synthetic chemicals used in nonstick cookware coatings, including PTFE—better known as Teflon. These coatings prevent food from sticking and make cleanup easy, but they’ve raised concerns about environmental persistence and potential health effects when overheated.

The FDA regulates PFAS in cookware and generally considers PTFE coatings safe under normal use. But the risk emerges when PTFE is heated above roughly 500°F (260°C). At that point, the coating can degrade and release fumes that may cause temporary flu-like symptoms in people—sometimes called “polymer fume fever.” Air fryers often run at high temperatures (commonly up to 400–450°F), so the concern is understandable.

That’s why many manufacturers, including Cosori, have shifted to alternative materials. Ceramic and stainless steel options eliminate PFAS entirely, removing even the theoretical risk from overheating.

Why the PFAS Question Sticks for Air Fryer Shoppers

When you search for air fryers, the phrase “nonstick coating” appears everywhere. It’s a selling point for easy cleaning. But now that PFAS have become a household concern, shoppers want to know whether that convenience comes with hidden trade-offs.

The confusion is understandable: not all nonstick coatings are the same. Some air fryers use PTFE (a type of PFAS), while others use ceramic sol-gel coatings made from silica. Both can be labeled “nonstick,” but only one contains PFAS. Cosori’s shift to ceramic and stainless steel means you can get nonstick convenience without the “forever chemical” concern.

• PTFE coatings (Teflon): These are a type of PFAS. They work well but may release fumes if overheated above ~500°F. Older Cosori models may still use PTFE.
• Ceramic coatings (sol-gel): Made from silica sand, these are PFAS-free and can handle higher temperatures without releasing toxic fumes. The Cosori TurboBlaze uses this coating.
• Stainless steel: Completely coating-free, so no PFAS at all. The Cosori Iconic Stainless Steel model features a bare stainless steel cooking chamber.
• Mixed surfaces: Some air fryers have a ceramic basket but a PTFE drip tray—check the full specifications. Cosori’s current models list all cooking surfaces as PFAS-free.

Once you know the material, the answer becomes clear. If you own or are considering an older Cosori model, check the product description for “PTFE” or “Teflon.” If you see it, the coating does contain PFAS. For the latest models, the brand has made PFAS-free construction a headline feature.

Cosori’s Official Position on PFAS in Its Air Fryers

Cosori’s own disclosure page acknowledges that PTFE is a common PFAS used in nonstick cookware. The company doesn’t claim every product is PFAS-free for life—older models may still use PTFE. But for the current generation, the message is clear: the TurboBlaze and Iconic Stainless Steel lines are designed without PFAS.

The TurboBlaze 6 Qt air fryer features a PFAS-free ceramic coating on the basket and crisper tray. Amazon’s product page calls it “enhanced durability and heat resistance compared to traditional PTFE coatings.” The Iconic Stainless Steel model goes a step further with a PFAS-Free Cooking Chamber made entirely of stainless steel—no coating at all.

For anyone looking to avoid PFAS entirely, a terrawellness guide offers tips on identifying PFAS-free air fryers, including checking for 100% ceramic coatings and stainless steel construction. Cosori’s current lineup checks both boxes.

If you’re buying a new Cosori today, the TurboBlaze or Iconic models are your safest bet for PFAS-free cooking. Secondhand or older units may still contain PTFE, so always verify the model number before purchasing.

How to Confirm Your Air Fryer Is PFAS-Free

If you already own a Cosori air fryer or are shopping for one, here’s a simple checklist to decide whether it contains PFAS.

1. Check the model name and year: Cosori’s PFAS-free models are the TurboBlaze (released 2023) and Iconic Stainless Steel (released 2024). Older models like the Pro II, Lite, and original Smart series used PTFE.
2. Read the product description: Look for the words “PFAS-free,” “PTFE-free,” or “ceramic coating.” If the description says “nonstick” without specifying the material, assume it’s PTFE until proven otherwise.
3. Inspect the basket interior: Ceramic coatings are usually a solid color (often white or dark gray) with a smooth, almost glassy finish. PTFE coatings tend to be darker and more matte. Stainless steel is metallic with visible grain.
4. Contact Cosori support: You can email the company with your model number. They typically respond quickly and can confirm the basket material.

Taking these steps takes only a few minutes but removes all doubt. Once you confirm the material, you can cook confidently knowing your air fryer matches your health and environmental priorities.

Ceramic Coating vs. PTFE: Which Performs Better?

Ceramic and PTFE coatings each have strengths and weaknesses beyond just PFAS content. Understanding them helps you decide which trade-offs you’re comfortable with.

Ceramic (sol-gel) coatings are made from silica—essentially sand. They’re PFAS-free and can handle temperatures well above 500°F without releasing fumes. The trade-off, according to Caraway Home’s comparison, is that ceramic may lose its slickness faster than PTFE, especially with metal utensils or abrasive cleaning. Many users find ceramic stays nonstick for one to two years with proper care, while PTFE can last longer when kept below 500°F.

Stainless steel, on the other hand, has no coating at all. It’s durable, scratch-resistant, and completely inert. However, food can stick more easily than with either ceramic or PTFE. Tomsguide’s coverage notes that the new ceramic coating in Cosori’s line is a significant shift in the industry, calling it a “game-changer” because Cosori ditches PFAS without sacrificing nonstick performance for most users.

For most people, the choice comes down to longevity versus PFAS avoidance. If you’re willing to replace a basket every couple of years, ceramic is a strong fit. If you want something that will last for a decade, stainless steel is the better bet—even if it requires a little more oil or attention to prevent sticking.

The Bottom Line

Newer Cosori air fryers—specifically the TurboBlaze and Iconic Stainless Steel models—are PFAS-free. If you already own an older Cosori with a PTFE coating, the air fryer is still safe to use under normal temperatures, but the coating does contain PFAS. For a worry-free purchase, stick with the models explicitly labeled as PFAS-free.

Your specific cooking habits and cleaning routine should guide your choice—ceramic coating offers easy release with moderate lifespan, while stainless steel is virtually indestructible. If you decide on a ceramic model, Cosori’s TurboBlaze is the most tested PFAS-free option on the market today.
