Compare Air Fryers
Ninja Foodi 6-in-1 8-Qt. 2-Basket Air Fryer with DualZone Technology 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 substrate material not disclosed by Typhur for the Sync model.
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 degrades over time.
The baskets are steel with PTFE coating. No food-grade qualification (304/316) confirmed.
Typhur does not state basket base material for the Sync. HALT flag -- cannot publish score without resolution.
Ninja makes no PFAS-free claim for this product. PTFE coating is a PFAS compound confirmed present on the baskets.
Typhur claims PFAS-free without third-party certification.
Two independent square baskets let you cook two different foods at different temperatures simultaneously.
10.3 x 10.3 inch square basket for optimal crisping.
1690 watts total provides strong heating across both cooking zones.
1750 watts for fast preheat and strong cooking.
All four removable parts (two baskets, two crisper plates) are dishwasher-safe.
All removable parts are dishwasher-safe.
No noise level data is published.
No noise level data published for the Sync.
Standard 1-year limited warranty from Ninja.
1.5-year warranty, slightly above standard.
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 a 1750W square-basket air fryer with ceramic PFAS-free coating and wireless probe thermometer.
You can accept undisclosed base materials and trust Typhur's 'non-toxic' claim.
You want dishwasher-safe parts with a 1.5-year warranty.
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.
Typhur does not disclose the basket or grill plate substrate materials for the Sync model. This material opacity is the single biggest safety concern and cannot be resolved without brand confirmation. HALT flag on container_material.
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 full material transparency -- basket and crisper plate substrates are not disclosed.
You need third-party PFAS-free certification or ETL/UL electrical safety certification.
You want to know exactly what your food touches during cooking -- substrate is unknown.

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 Ninja Foodi 6-in-1 8-Qt. 2-Basket Air Fryer with DualZone Technology (stainless steel basket, 3.9/10 safety) uses materials I'm more comfortable with at high heat. The Typhur Sync Air Fryer's undisclosed material basket scored 2.6/10. 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 Ninja 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.
