Cosori Air Fryer Pro LE 5-Qt Airfryer
Pass on this model until Cosori reveals nonstick coating chemistry or switches to Teflon-type coating-free.
The Pro LE has a nonstick-coated aluminum basket, but Cosori reveals nothing about the Teflon-family coating type or PFAS content. Industry-standard nonstick coatings frequently contain PFAS or substitutes.

What Cosori Air Fryer Pro LE 5-Qt Airfryer is made of, ingredients and materials
The cooking basket is aluminum with an unnamed nonstick coating. Aluminum itself is generally stable during cooking at air fryer temperatures (typically 180-200°C), but the nonstick surface is the critical unknown. Cosori has not publicly specified whether the coating is Teflon-type coating-based (Teflon), ceramic, silicone, or another formulation, which prevents independent assessment of fume risk or durability. Coating degradation or scratching can expose underlying aluminum, which may leach trace amounts under acidic or prolonged contact, though air fryer use cycles are brief.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.
Teflon-type coating fume risk (nonstick coating)
Cosori has not disclosed the nonstick coating chemistry. If Teflon-type coating-based, overheating (above ~260°C) can release fluorinated gases; air fryers typically stay below 200°C, but damaged or degraded coating increases risk. Unknown coating type makes independent risk assessment impossible.
Nonstick coating degradation over time
All nonstick coatings on cookware degrade with use, scratching, or aggressive cleaning. Once the coating chips or peels, the underlying material is exposed. No specific durability data for this Cosori model is published, but user reviews and manufacturer warranty terms (typically 1-2 years) suggest coatings are expected to wear.
Off-gassing or odor on first use
New air fryers, especially those with nonstick coatings and plastic housings, may emit a mild odor during initial heating cycles. This is not necessarily hazardous but is typical of new nonstick cookware. Ensure ventilation the first few times you use the unit.
What’s reassuring
Aluminum leaching
Uncoated aluminum can leach trace amounts in acidic foods or with prolonged contact; the nonstick coating provides a barrier. No recalls or documented incidents of aluminum leaching from this model are on record. Risk is low if the coating remains intact.
Electrical housing and cord safety
No recalls or safety issues with electrical components, housing materials, or power cord integrity are on record for this model. Standard UL or equivalent certification applies to the heating element and electronics.
How is this PFAS grade calculated?
The brand's record and disclosure
Cosori does not publicly disclose the chemistry of its nonstick coatings or provide PFAS-free certification. No major safety recalls tied to nonstick degradation or chemical release have been publicly documented for this specific model, but the lack of transparency on coating composition is a red flag for consumer choice. Cosori markets the product as having a 'professional-grade nonstick coating' without specifying material class, compliance standard, or PFAS absence, which is inconsistent with industry leaders who name their coating systems (e.g., 'ceramic' or 'Teflon-type coating-free').
How it compares in its category
Many competing air fryer brands (Ninja, Instant Pot, Philips) now advertise ceramic or ceramic-hybrid coatings explicitly and market PFAS-free or Teflon-type coating-free claims. Cosori's silence on this point, combined with the PFAS safety score of 15/100, suggests the nonstick system may be conventional Teflon-type coating-based rather than a newer alternative. Budget air fryers from less-known brands often use similarly undisclosed coatings; premium models tend to be more transparent. The 5-Qt capacity and Pro LE designation do not differentiate the nonstick safety profile.
If you buy it
Never exceed the manufacturer's stated maximum temperature, typically around 200°C (400°F), to minimize nonstick fume risk if the coating is Teflon-type coating-based. Inspect the basket regularly for scratches, peeling, or discoloration; discontinue use if the coating shows visible wear. Hand-wash the basket gently with soft sponges; avoid abrasive scouring pads and the dishwasher, which accelerate coating degradation. Allow the unit to cool before opening the basket to avoid inhaling any fumes from a hot surface, and ensure the kitchen is well-ventilated during use.
