Cosori Smart 12 in 1 26qt Air Fryer Cooling Rack
Lower PFAS concern, this is a cooling rack, not a nonstick-coated cookware item.
This product is a stainless steel cooling/drying rack accessory for an air fryer, not cookware with a nonstick coating. Stainless steel mesh is inherently non-absorptive and does not require PFAS-based water or grease repellency treatments.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
This is a stainless steel mesh grate designed to cool baked goods after air frying. Stainless steel (typically 18/8 or 18/10 chromium-nickel alloy) is chemically stable at typical kitchen temperatures and does not leach metals into food or the air under normal use. There is no nonstick coating (Teflon-type coating, ceramic, or other) applied to the mesh, which eliminates the primary concern of fume release from degraded coatings during high-heat cooking.
The brand's record and disclosure
Cosori manufactures small appliances and kitchen accessories but maintains minimal public disclosure on material sourcing, safety testing, or PFAS policy. No major recalls specific to this cooling rack model are on record, and the product carries no notable third-party certifications (e.g., NSF, FDA letter of non-objection). The brand has not faced established safety controversies tied to this accessory type.
How it compares in its category
Stainless steel cooling racks are among the safest options in the accessory category because they require no coating maintenance and are inert across the temperature range of air fryer and toaster oven use. Wire racks made from painted steel or aluminum may pose marginal concerns around coating wear; silicone or ceramic racks carry their own material questions. Stainless steel avoids these issues entirely.
If you buy it
Wash the rack by hand or in the dishwasher before first use to remove manufacturing residue. Inspect the welds and mesh periodically for corrosion or loose strands, especially if exposed to acidic foods or high-moisture environments. Stainless steel is durable and does not require special care; replace only if structural damage occurs. Avoid abrasive scouring that may damage the finish, though minor surface wear does not compromise safety.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Metal leaching (aluminum, iron, nickel)
Stainless steel 18/8 alloys are designed to resist corrosion and do not leach measurable quantities of chromium or nickel under normal kitchen use; no reports of leaching from Cosori steel cooling racks.
Coating degradation and fume risk
This product has no applied nonstick or enamel coating, eliminating the primary mechanism for Teflon-type coating fume release or ceramic glaze contamination. The bare mesh is not subject to chipping or peeling.
Structural integrity and food contamination
Wire mesh can accumulate food debris in joints or develop small corrosion pits over years of use in humid conditions; regular inspection and cleaning minimize risk. Loose wires or rust spots are rare but should trigger replacement.
Manufacturing residue or machining oils
Stainless steel mesh manufactured abroad may carry light machine oil, coolant residue, or dust. Pre-use washing removes these; no specific reports of residue toxicity on Cosori racks.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
