Compare Air Fryers
Typhur Dome 2 Air Fryer scores higher on safety - here's why.
The most important dimensions, side by side.
The crisper plates are aluminum without a food-grade qualification. Without knowing if the aluminum is treated, there is some risk of leaching with acidic foods.
Grill plate is aluminum with ceramic coating. 'Durable aluminum' stated but no food-grade qualification.
The cooking baskets use PTFE (Teflon) nonstick coating. PTFE is a PFAS compound that can release toxic fumes when overheated or degraded.
Ceramic coating is PFAS-free and PTFE-free. Safer than PTFE but ceramic coatings degrade over time.
The baskets are steel with PTFE coating. No food-grade qualification (304/316) confirmed.
'Durable aluminum alloy' without food-grade qualification.
Ninja makes no PFAS-free claim for this product. PTFE coating is a PFAS compound confirmed present on the baskets.
Typhur claims PFAS-free with SGS test report but no FDA food-contact certification.
Two independent square baskets let you cook two different foods at different temperatures simultaneously.
Dome-style round cooking surface trades crisping evenness for unique design.
1690 watts total provides strong heating across both cooking zones.
1750 watts provides fastest preheat and strongest temperature maintenance.
All four removable parts (two baskets, two crisper plates) are dishwasher-safe.
Basket is dishwasher-safe.
No noise level data is published.
55dB is near-quiet operation. Some reviewers measured 59-60dB in practice.
Standard 1-year limited warranty from Ninja.
18-month limited warranty, slightly above standard 1 year.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You need dual-zone cooking capability to prepare two different foods simultaneously and prioritize performance over material safety.
You are comfortable with PTFE coatings on food-contact surfaces and want a proven dual-basket design.
Dishwasher-safe parts and dual-zone convenience outweigh material safety concerns for your household.
You want the quietest air fryer available (55dB) with ceramic PFAS-free coating.
You prioritize usability and quiet operation over verified food-grade materials.
You want the strongest wattage (1750W) for fastest cooking.
The main thing to know
PTFE-coated baskets and bare-aluminum crisper plates mean both food-contact surface types raise safety concerns. No safety certification could be verified, and the SharkNinja product page returns a 404 error.
Despite ceramic-standard PFAS-free coating and excellent usability (55dB quiet, dishwasher-safe), bare aluminum construction without food-grade qualifier and no electrical safety certification limit the overall score. At $399, the safety gap is hard to justify.
Skip this if you...
You want PFAS-free or PTFE-free food-contact surfaces -- PTFE is confirmed on the baskets.
You need a safety certification (UL/ETL) -- none could be verified; the SharkNinja product page returns 404.
You prefer food-contact surfaces made of glass or bare stainless steel with no coatings.
You want a product with active manufacturer support -- the 404 product page suggests possible discontinuation.
You need verified food-grade aluminum or stainless steel construction.
You need third-party PFAS-free certification (not just manufacturer claim).
You need ETL/UL electrical safety certification.
You want better crisping performance -- square baskets outperform round in testing.
Neither of these quite what you're looking for?
I've reviewed all Air Fryers options at every price pointEvery Air Fryers in our database is scored using R3's deterministic scoring system - the same inputs always produce the same score. For this comparison, we evaluated Ninja and Typhur across 3 independent criteria: Safety (90%), Efficacy (7%), Usability (3%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
The Ninja Foodi 6-in-1 8-Qt. 2-Basket Air Fryer with DualZone Technology uses a stainless steel basket with a bare-aluminum crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the Typhur Dome 2 Air Fryer (bare-aluminum basket, 4.3/10 safety) uses materials I'm more comfortable with at high heat. The Ninja Foodi 6-in-1 8-Qt. 2-Basket Air Fryer with DualZone Technology's stainless steel basket scored 3.9/10. In our scoring system, basket material accounts for a significant portion of the safety pillar, which is our highest-weighted scoring factor.
For families, capacity comes first: check the capacity specs for your family size. Overall, I'd lean toward Typhur for most families.
304 stainless steel is inherently PFAS-free and won't off-gas at any cooking temperature. Nonstick coatings (PTFE/Teflon) are stable below 400°F but can begin degrading above that threshold. In our scoring system, stainless and borosilicate glass baskets consistently score higher on the safety pillar. That said, a well-maintained nonstick basket from a reputable brand still meets safety baselines - it's a question of margin, not danger.
