Cosori Iconic Smart Air Fryer
Skip until Cosori discloses nonstick coating chemistry.
Cosori's Iconic Smart Air Fryer uses a nonstick-coated surface it won't describe publicly. No lab verification or third-party certification addresses the specific PFAS risk here.

What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cookware is a category where PFAS exposure is more common.
Teflon-type coating-based nonstick coating degradation and fume release
If the basket uses traditional Teflon-type coating (Teflon), heating above 500°F can produce polymer fume inhalation event (Teflon-type coating), though air fryers typically operate 350-400°F. Cosori does not confirm the coating type, so this risk cannot be ruled out; degraded or flaking coating increases inhalation exposure.
PFAS
Nonstick coatings may contain PFAS "forever chemicals" (PFAS) to impart water and oil repellency. Repeated heating cycles can degrade the coating and potentially release fluorochemicals into food. Cosori's refusal to disclose coating chemistry means PFAS exposure is unquantified but plausible.
Source: ATSDR ↗Unspecified plastic housing leachables
The external housing and internal plastic components are not identified by polymer type (ABS, polycarbonate, polyethylene, etc.) in public materials. If polycarbonate, BPA leaching is theoretically possible under repeated heating; if recycled plastic, contaminant loads are unknown.
Nonstick coating mechanical wear and microparticle ingestion
Air fryer baskets with worn or scratched nonstick coatings can shed microscopic particles into food during cooking. This is a known failure mode across the air fryer category, including Cosori units, though no specific recall has been issued for this brand.
Inadequate cleaning and bacterial/mold growth in basket crevices
Nonstick basket surfaces with deep ridges or crevices can trap moisture and food residue, creating environments for bacterial or mold proliferation if not thoroughly dried. This is a maintenance risk rather than material toxicity but affects food safety.
The full breakdown
What it's made of and why it matters
The Cosori Iconic uses a nonstick-coated basket and cooking tray, but Cosori has not publicly disclosed whether this coating is Teflon-type coating-based (traditional Teflon), ceramic, or an alternative formulation. The housing is plastic (type unspecified in public materials), and the heating element is electric. Without transparency on coating chemistry, users cannot definitively assess fluorochemical exposure or whether the coating meets current PFOA phase-out standards.
The brand's record and disclosure
Cosori does not maintain a public materials disclosure policy or third-party certifications (NSF, Cradle to Cradle) specific to nonstick safety. The company has faced no major recalls tied to nonstick coatings as of available records, but their silence on PFAS and coating composition contrasts with competitors like Ninja and Instant Pot, which have begun disclosing safer alternatives or phase-out commitments. This lack of transparency is a red flag for informed purchasing.
How it compares in its category
Most air fryers (Ninja, Instant Pot, Philips) use similar nonstick baskets without full public disclosure, making this a category-wide issue rather than a Cosori outlier. However, some brands now offer ceramic or Teflon-type coating-free options. Cosori's lack of stated material alternatives puts it in the middle of the transparency spectrum for the category, neither leading nor trailing competitors.
If you buy it
Operate below 400°F to minimize any nonstick coating degradation or fume release; Teflon-type coating and some ceramic coatings can degrade above this threshold. Replace the basket or tray every 12-24 months of regular use, sooner if the coating visibly flakes or peels. Hand-wash only and avoid abrasive scrubbers to preserve the coating. Ensure good kitchen ventilation during use as a precaution against any fume release from the nonstick layer.
