Cosori Mini Air Fryer 2.1 Qt
Avoid until Cosori clarifies its nonstick formula.
This compact Cosori model has a nonstick-coated basket with undisclosed composition. Most air fryer nonstick coatings historically used Teflon-family coating like Teflon-type coating, creating elevated PFAS concern without transparency.

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.
Non-stick coating degradation and fume release
Unknown coating type means unknown degradation threshold. If Teflon-type coating-based, overheating or scratching can release fumes; if ceramic, durability over time is less documented. Cosori's silence prevents risk assessment.
Coating peeling into food
Non-stick coatings can shed particles if scratched or degraded over time. Risk increases with aggressive cleaning or utensil use; regular inspection is essential.
Polymer off-gassing during initial use
New non-stick cookware often releases minor VOC odors on first heating. This is typically not hazardous but unpleasant; ensure good ventilation during first few uses.
Teflon-type coating decomposition fumes if coating is Teflon-type coating
If the basket coating is Teflon-type coating and is overheated or damaged, fumes can occur. Risk is low under normal use but cannot be ruled out without material disclosure from Cosori.
What’s reassuring
Aluminum leaching from heating element
Internal heating components are likely aluminum; direct food contact with uncoated aluminum is minimal in air fryers. No reported leaching issues specific to Cosori models.
The full breakdown
What it's made of and why it matters
The Cosori Mini Air Fryer uses a non-stick coated basket, but Cosori has not publicly specified whether the coating is Teflon-type coating-based (Teflon-like), ceramic, or another polymer. This matters because non-stick coatings in cookware can degrade when overheated, scratched, or used improperly, potentially releasing harmful fumes or particulates into food. The heating element itself reaches approximately 400F degrees, well within the range where some coatings begin to break down if damaged or if the basket is preheated empty or overheated.
The brand's record and disclosure
Cosori does not publicly disclose non-stick coating chemistry on product specifications or safety documentation for this model. The company has no known published PFAS reduction commitment or third-party certifications (such as GOTS or Cradle to Cradle) specific to cookware materials. This silence is notable in a product category where PFAS disclosure has become increasingly common among competitors; absence of clarity suggests either uncertainty on the brand's part or lack of transparency priority.
How it compares in its category
Most competing air fryer brands (Instant Pot, Ninja, Philips) now label their baskets as either Teflon-type coating-free ceramic or explicitly disclose Teflon-type coating use. Cosori's lack of specification puts this model at a transparency disadvantage, even if the actual material is safe. Budget air fryers often use the same undisclosed coatings, so this is not unusual for the price tier, but it is increasingly expected that brands clarify composition at purchase.
If you buy it
Do not preheat the basket empty or leave it running unattended above 400F. Inspect the basket before each use for scratches, peeling, or discoloration; replace if visible damage appears. Hand-wash the basket only (do not put in dishwasher), use soft sponges, and avoid metal utensils to prevent coating damage. Keep the unit well-ventilated during use; if you smell unusual fumes, stop use immediately and contact Cosori support to clarify coating type.
