Ninja Crispi Pro 6-in-1 Glass Air Fryer
Glass construction means lower PFAS concern than typical nonstick air fryers.
This Ninja model features a glass cooking chamber that doesn't need PFAS coatings, with stainless steel basket and heating elements. Ninja stays silent on PFAS, but borosilicate glass poses lower risk than coated nonstick cookware.

Material
Glass cooking vessel with stainless steel components
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
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.
Thermal shock / glass breakage risk
Glass cookware is susceptible to cracking if exposed to rapid temperature changes (e.g., adding cold food to hot vessel). This is a mechanical safety hazard rather than a chemical one, but can cause injury or product failure.
What’s reassuring
Uncoated safe material
Bare cast iron, stainless steel, carbon steel, or glass with no PFAS coating.
Gasket / seal leachables
Rubber or silicone seals in the lid or heating element connections are not publicly documented to contain harmful additives for this model. However, Ninja does not disclose seal composition; aging seals could theoretically leach if not replaced periodically.
Stainless steel off-gassing
Food-grade stainless steel does not off-gas at air fryer operating temperatures. No documented risk for this product.
Aluminum frame leaching
The frame and housing are stainless steel, not aluminum, so aluminum leaching is not a concern for this model.
Microplastics
Glass does not shed microplastics and does not contain nonstick polymers that could fragment. This hazard is eliminated by the material choice.

What it's made of and why it matters
The Ninja Crispi Pro uses a glass cooking vessel rather than ceramic or metal coated with nonstick polymers. Glass is chemically inert across normal cooking temperatures and does not leach contaminants into food. The stainless steel frame and heating elements are stable materials that do not degrade or release heavy metals under typical air fryer operating conditions (up to around 400-450°F). This material choice avoids the primary hazard category for air fryers, which is degradation of nonstick coatings at high heat.
The brand's record and disclosure
Ninja (SharkNinja Operating LLC) does not publicly disclose detailed material safety documentation or independent third-party certifications for this specific model. The brand has not faced major recalls related to chemical leaching or coating hazards on air fryer products, though transparency on PFAS use in gaskets or seals remains absent. No formal statement on PFAS avoidance or use has been found in public records; silence on this issue is typical for the category but represents a disclosure gap rather than evidence of contamination.
How it compares in its category
Most air fryers use aluminum baskets with ceramic nonstick coatings (which may contain Teflon-type coating or PFOA precursors) or stainless steel mesh trays. The glass vessel approach is less common and reduces risk of coating degradation fume release at high temperature. However, glass is heavier and can crack if subjected to thermal shock or impact; this is a mechanical rather than chemical risk that users of ceramic or metal alternatives do not face as acutely.
If you buy it
Avoid rapid temperature changes (do not add cold food or liquid to a preheated glass vessel). Hand wash the glass rather than using abrasive scrubbers to prevent microfractures that could lead to breakage during cooking. Monitor seals and gaskets visually; replace them if discolored or hardened, as aging rubber can degrade. The glass itself does not need replacement unless cracked; it does not degrade chemically at air fryer temperatures.
