De'Longhi Livenza Air Fry Convection Oven
Avoid until De'Longhi discloses the interior coating type.
The interior cooking surfaces on this convection oven remain unspecified by De'Longhi. Standard designs often use non-stick coatings that may contain PFAS, but specific materials aren't documented.

Material
Stainless steel housing; interior cooking surfaces unspecified (likely non-stick or ceramic-coated)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
Teflon-type coating (Teflon) fume release under thermal stress
Interior coating type unconfirmed; if Teflon-type coating-based, overheating or prolonged preheating may release polymer fumes. Risk is low at normal cooking temps (350-400F) but rises significantly above 500F.
Coating degradation and microparticle ingestion
Any non-stick or ceramic coating can flake with age, rough handling, or abrasive cleaning. Air fryer baskets see frequent mechanical contact; chipped coating particles may enter food. No specific recalls exist for this model.
Bacterial or mold growth in heating chamber
Air fryer chambers can trap grease and moisture if not cleaned after each use. This is a maintenance issue, not a manufacturing hazard, but poor design that limits access worsens risk. De'Longhi's chamber design allows some accessibility.
What’s reassuring
Aluminum leaching from anodized surfaces
If the basket is hard-anodized aluminum (common in air fryers), properly sealed anodization prevents leaching. Risk is minimal unless coating is visibly damaged. De'Longhi does not confirm basket material publicly.
Heavy metals
Food-grade stainless steel (typically 304 or 316) is safe for cookware use. Nickel leaching is not a documented risk for exterior housing. Interior coating, if nickel-plated, is the only theoretical concern; not specified here.

What it's made of and why it matters
The De'Longhi Livenza has a stainless steel exterior housing, which is chemically inert and safe. The critical unknown is the interior cooking surface: air fryer baskets and chamber linings are typically either hard anodized aluminum, ceramic-coated steel, or non-stick polymer (Teflon-type coating/Teflon-type coating alternatives). De'Longhi's product pages do not specify which. If Teflon-type coating is used, overheating above 500F can release fumes; ceramic or hard-anodized surfaces carry minimal thermal risk but may degrade over years of use.
The brand's record and disclosure
De'Longhi does not publicly disclose interior coating composition or PFAS testing results for this model. The brand has no known formal certifications (NSF, Greenguard, etc.) for chemical safety in cookware. No major recalls or hazard reports have been documented for this specific model. This silence is typical of the air fryer category but limits consumer ability to assess coating risk before purchase.
How it compares in its category
Most mass-market air fryers (Ninja, Cosori, Instant, Philips) similarly omit interior coating specifications. Premium brands like Cosori and some Instant models have begun publishing Teflon-type coating-free or ceramic-lined options. The Livenza is mid-market: more transparent than budget brands, less transparent than premium competitors. Stainless steel housing is standard and not a differentiator.
If you buy it
Do not exceed manufacturer temperature guidance (typically 400F for cooking; max 450F calibration). Never preheat empty for extended periods, as this accelerates non-stick degradation. Inspect the basket and chamber annually for peeling, discoloration, or roughness; replace basket if coating shows wear. Hand-wash interior surfaces only; abrasive scrubbing damages any coating. Contact De'Longhi for interior material specification before purchase if PFAS or Teflon-type coating is a dealbreaker for you.
