12.5 Quart Air Fryer
Internal coating unknown; Siemens offers no PFAS disclosure.
Siemens does not publicly disclose PFAS status for this air fryer. The basket and internal surfaces lack specification, and the nonstick coating identity remains unknown.

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 fume inhalation (thermal decomposition)
If the internal coating is Teflon-type coating-based (common in air fryers), heating above 500°F can release polymer fumes; Siemens does not specify the coating type or safe temperature ceiling. Risk is mitigated by typical air fryer operating ranges (350, 400°F) but unquantified given lack of material disclosure.
Coating degradation and particle ingestion
Without specification of coating durability or material, users cannot assess whether flaking or peeling will occur after repeated heating cycles. Air fryer baskets experience high thermal stress; poor-quality coatings are known to degrade within months of regular use.
Non-stick coating off-gassing at normal operating temperatures
While Teflon-type coating fume syndrome requires extreme temperatures (600°F+), some modern coatings and spray-applied non-sticks can emit volatile compounds at lower thresholds (350, 400°F) during normal air fryer use, especially on first use. Siemens provides no safe use or ventilation guidance.
What’s reassuring
Aluminum leaching from basket or housing
Most air fryer baskets are stainless steel or coated aluminum; if aluminum is uncoated or the coating degrades, mild acidic foods can leach aluminum, though levels in typical use remain within regulatory limits. Siemens likely uses food-grade materials, but this is unconfirmed.
Electrical or heating element safety
No recalls or safety issues documented for this model; Siemens is a reputable manufacturer. Standard electrical safety standards apply, and this product likely meets CE/UL marks in target markets.
The full breakdown
What it's made of and why it matters
The Siemens 12.5 quart air fryer uses a heating element, perforated metal basket, and internal cooking surfaces typical of the category. Siemens does not publicly specify the non-stick or anti-corrosion coating on internal components, which is the primary concern for consumer exposure during heating. Most air fryer baskets use either Teflon-type coating-based non-stick (which carries fume risk at high temperatures) or ceramic or silicone alternatives. Without material transparency, you cannot assess whether the coating degrades or releases particles under the high heat cycles air fryers sustain.
The brand's record and disclosure
Siemens is primarily a B2B industrial and appliance manufacturer, not a consumer safety leader. The company has not published voluntary PFAS disclosures or certifications (such as GOTS, Bluesign, or similar consumer appliance standards) specific to air fryers. Siemens maintains EU compliance records but does not exceed regulatory minimums in public safety communications for kitchen appliances. No major recalls or safety controversies are documented for this specific model, though the lack of disclosure remains a compliance red flag in a category where PFAS use is widespread.
How it compares in its category
Most commercial air fryers (Instant Pot, Ninja, Cosori, Philips) similarly fail to disclose coating composition upfront, making Siemens typical rather than exceptional. A few brands (e.g., Cosori) market ceramic or Teflon-type coating-free baskets explicitly; others provide EU/LFGB certifications that hint at lower PFAS risk. The 12.5 quart size is on the larger end, which means longer heating cycles and more surface area exposure; smaller units may pose lower cumulative risk. At this price point and brand tier, expect EU compliance but not transparency beyond legal minima.
If you buy it
Avoid preheating above 400°F (204°C) for extended periods, as this is where Teflon-type coating fume risks rise in non-stick coatings. Do not use metal utensils on internal surfaces; hand-wash the basket gently to preserve any coating. Replace the basket or non-stick liner if you notice flaking, discoloration, or degradation. Contact Siemens directly before purchase to request coating composition documentation; silence on this question after inquiry is a sign to reconsider. Ensure adequate kitchen ventilation during use, especially on high-temperature cycles.
