What Big Boss 16 Qt. Black Built-in Timer is made of, ingredients and materials
The Big Boss air fryer uses a nonstick-coated cooking surface, but Big Boss has not publicly disclosed the specific chemistry of this coating. The housing and internal components appear to be plastic and metal alloys, but material composition details are unavailable. Nonstick coatings on cookware are the primary vector for PFAS exposure during cooking, and without transparency on whether this uses Teflon-type coating, GenX, or other fluorinated alternatives, actual safety cannot be assessed. Heating nonstick coatings above their recommended temperature threshold can release fumes.
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.
PFAS
Big Boss has not disclosed whether this coating is Teflon-type coating-based or contains legacy PFAS compounds. Given the brand's silent stance and the prevalence of Teflon-type coating in budget air fryers, fluorinated coating is probable. Heating above 400-500F can release fumes; air fryer operation often exceeds 350F.
Source, ATSDR ↗Coating degradation and particle ingestion
Budget nonstick coatings commonly show wear within 1-2 years of normal use. Peeling or flaking coating particles can be ingested with food, with unknown long-term health effects. No durability testing for this specific model is publicly available.
Aluminum leaching from internal components
Air fryer heating elements and baskets often contain aluminum alloys. Acidic foods or prolonged contact can promote leaching. Big Boss does not specify whether aluminum components are anodized or otherwise treated to prevent migration.
Formaldehyde / VOCs
The external plastic housing is not identified by type (ABS, polycarbonate, etc.). Budget air fryers may use lower-grade thermoplastics that off-gas VOCs when heated near the cooking chamber. No off-gassing testing or material certifications are reported.
Source, ATSDR ↗Thermal fume inhalation from nonstick degradation
Air fryers operate at sustained high temperatures in an enclosed or semi-enclosed cooking space, concentrating fumes near the user's breathing zone. Without coating chemistry disclosure, risk of Teflon-type coating polymer fume fever or other thermal degradation products cannot be ruled out.
How is this PFAS grade calculated?
The brand's record and disclosure
Big Boss has maintained silence on nonstick coating chemistry and PFAS content across its product line. No third-party certifications (such as GREENGUARD or OEKO-TEX equivalents for cookware) are claimed on this model. The brand has not published statements addressing PFAS phase-out or transitions to coatings with lower concern, which is increasingly expected of major cookware manufacturers. This lack of disclosure contrasts with competitors who now explicitly commit to PFOA-free or fluorine-free nonstick alternatives.
How it compares in its category
Air fryers are a growing category, and nonstick coatings are nearly universal for ease of cleaning. However, brands like Instant Pot and Cosori have begun disclosing PFAS-free or lower-risk coatings; Big Boss does not. Most premium air fryers now highlight coating safety as a selling point. The 16 qt capacity is large, but size does not offset the lack of material transparency, which is now a standard expectation in the cookware market.
If you buy it
Do not use at temperatures above the manufacturer's recommended setting, as excess heat accelerates coating degradation and fume release. Hand-wash only; abrasive scrubbing or dishwasher use damages nonstick coatings and releases particles. Inspect the cooking surface regularly for scratches, discoloration, or peeling, and discontinue use if damage is visible. Replace the unit if the coating shows signs of wear within the first 1-2 years, as this suggests poor durability.
