Cosori Dual Blaze Smart Air Fryer
Skip until Cosori reveals nonstick coating chemistry or testing results.
This Cosori model uses a nonstick-coated basket without public disclosure of what that coating contains. Standard nonstick air fryers frequently rely on Teflon-type coating or Teflon-family coating that may harbor PFAS.

Material
nonstick-coated cooking basket (type unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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 fume risk (thermal degradation)
If the coating is Teflon-type coating-based, overheating or basket damage can release fluorinated fumes; Cosori does not specify maximum safe temperature for the basket coating or confirm absence of Teflon-type coating, making risk assessment incomplete.
Nonstick coating degradation and shedding
All nonstick air fryer baskets degrade over time with repeated use and temperature cycling; visible flaking or peeling is common after 1-3 years depending on care, at which point basket replacement is recommended.
Off-gassing of volatile organic compounds (VOCs) from housing or wiring insulation
Plastic components and electrical insulation in the housing and handle may emit low levels of VOCs during initial use or if the unit is opened; typical mitigation is first-use ventilation and avoiding inhalation of early operating fumes.
What’s reassuring
Aluminum leaching from heating elements or housing
No reports or testing of aluminum leachate from Cosori air fryer components; most air fryer housings and heating elements are aluminum alloy and do not directly contact food, lowering leaching risk compared to cookware.
Electrical or burn safety during operation
No established safety recalls for the Dual Blaze model; standard air fryer burn risk from hot surfaces applies to all models in this category.
The full breakdown
What it's made of and why it matters
The Cosori Dual Blaze features a nonstick-coated cooking basket, but Cosori has not publicly disclosed whether the coating is Teflon-type coating-based (traditional Teflon), ceramic, or proprietary formulation. The heating element and housing materials are not specified in available product documentation. Nonstick coating chemistry is critical because Teflon-type coating-based systems release fluorinated compounds when degraded or overheated, while ceramic coatings carry different durability and leaching profiles.
The brand's record and disclosure
Cosori does not publish detailed material safety data or coating chemistry specifications for this product model. The brand has not issued public PFAS testing results or commitment statements comparable to competitors like Ninja or Instant Pot, which have begun voluntary disclosure. No established safety recalls or independent testing failures are on record for the Dual Blaze specifically, but silence on coating composition is a red flag in the air fryer category.
How it compares in its category
Most mid-range air fryers use Teflon-type coating or ceramic nonstick coatings without full transparency. Cosori's lack of disclosure is less transparent than Ninja (which clarifies Teflon-type coating use and safe temperature limits) but not unusual in the budget-to-mid market. Higher-end or eco-focused brands increasingly specify stainless steel or ceramic-only baskets with published safety data, making those safer choices if PFAS risk concerns you.
If you buy it
Do not exceed the manufacturer's temperature guidelines, as overheating any nonstick coating accelerates degradation and potential fume release. Replace the basket if the coating chips, peels, or shows visible wear; contact Cosori about replacement basket availability before purchase. Clean with soft tools only (no abrasive scrubbers) to preserve the coating. Request written confirmation from Cosori of the nonstick coating type and PFAS status before committing to the purchase if this is a concern for your household.
