The cooking vessel is borosilicate glass — chemically inert at any cooking temperature, no coatings to chip or degrade, and fully transparent so you can see exactly what's happening inside. It won't leach anything into your food, full stop.
The food-contact surfaces are stainless steel — uncoated, no PTFE, no ceramic nonstick. The grade isn't disclosed, so you can't independently verify corrosion resistance if you're cooking acidic foods frequently. Contact Our Place to confirm 304 (18/8) — if it is, this is one of the safest container materials available.
The crisper plate has a ceramic nonstick coating, which doesn't contain PTFE or PFOA per Ninja's claims — but no independent lab has verified it's free of PFAS binders that can appear in sol-gel ceramic formulations. If the coating is your main concern, that's a meaningful gap. Plan for hand-washing and non-metal utensils to extend its life.
The crisper plate is chrome-plated steel, which is food-safe at cooking temperatures. Modern chrome plating uses trivalent chromium — the safe form — but Our Place doesn't confirm this explicitly. Hand wash promptly and inspect weld points periodically for rust if the plating wears.
ETL Listed means the electrical components passed a safety review — it says nothing about whether the food-contact surfaces are PFAS-free. No independent lab (Mamavation, SGS, Intertek) has tested this fryer's ceramic crisper plate coating. If third-party chemical verification matters to you, it isn't here.
Our Place declares AB 1200 compliance, which legally prohibits the most acutely hazardous PFAS and heavy metals from food-contact materials. This is a brand self-declaration, not an independent lab result. Compliance also doesn't mean PFAS-free across the board — only the compounds named in the regulation.
At 271.93 W/qt, this fryer handles everyday family cooking well — wings, vegetables, reheating, and frozen foods all come out properly. For dense proteins like thick chicken thighs or pork chops, plan on flipping halfway through to get even browning.
At 53.6 watts per quart, this oven doesn't generate enough heat density to crisp dense proteins — think chicken thighs or pork chops — at full load. It handles reheating, toast, and lighter air frying well. If your household air fries frequently and in volume, this is a real limitation.
450°F covers the full cooking range: air frying, roasting, high-heat crisping, and finishing. You won't hit a ceiling on any standard recipe. At max temp, food can overcook fast — check it early.
The 450°F ceiling covers every common cooking task: air frying, roasting, broiling, and high-heat finishing. You won't hit a temperature wall mid-recipe. Just know that at max temp, food can go from perfect to overdone in under two minutes — stay close.
At 5.7qt, this fryer fits a single-batch cook for a family of 4 (roughly 1 lb of wings plus vegetables) per Good Housekeeping's testing. Ninja hasn't published interior bowl dimensions, so you can't confirm exact usable area — estimated interior diameter is around 9.5 inches based on exterior geometry.
At 31.7 quarts, this oven fits a 12-inch pizza or a full rotisserie chicken — confirmed by Our Place. The interior dimensions aren't officially published, so the listed capacity is the best available size reference. For families cooking in batches, plan for about 20 extra minutes per meal while the second batch catches up.
Every food-contact part is dishwasher-safe, so cleanup is load-and-forget. One caveat: repeated dishwasher cycles will wear down the ceramic nonstick coating on the crisper plate faster than hand-washing would.
Nothing goes in the dishwasher — not the basket, rack, or any accessory. Over a year of regular use, that adds up to 10-15 hours of hand washing. Perforated parchment sheets (rated to 450°F) or silicone liners cut cleanup to a quick wipe and make this oven significantly more livable day-to-day.
At 72 dB, this is loud enough that you'll need to raise your voice to hold a conversation in the same room while it's running. Evening use in an apartment or open-plan home will be noticeable to everyone nearby.
At 58 decibels, you'll hear it running but it won't interrupt a conversation across the room. It's comparable to a quiet dishwasher. In a studio or open-plan apartment with a bedroom nearby, it may be noticeable during early mornings or late nights.
One year covers manufacturing defects — standard for US air fryers. Accidental glass breakage from thermal shock (pouring cold water on a hot bowl) isn't covered after 90 days. If you pay with an Amex or Visa Signature card, you'll typically get the warranty doubled to two years at no extra cost.
One year covers manufacturing defects under normal use — that's the US standard for countertop appliances. It won't cover fan wear or degradation from heavy use over time. If you pay with an Amex or Visa Signature card, you typically get an automatic second year of coverage at no cost.
Everything you need to make the call — who each one is for, and who should skip it.
Go for it if you...
You cook for 5+ people regularly and the base Crispi's 4qt basket isn't big enough to get dinner on the table in one batch
You want a borosilicate glass cooking vessel — no coatings touching your food, fully transparent so you can watch the cook, and chemically inert even at high heat
You'll actually use multiple cooking modes — air fry, bake, roast, dehydrate, and steam — and want one appliance instead of five
You want a countertop oven with zero nonstick coating on any food-contact surface — the racks, basket, and interior are all bare stainless.
You need a true multi-mode oven that toasts, bakes, broils, air fries, and dehydrates without buying separate appliances.
Your family meals require real capacity — it holds a 12-inch pizza or a full rotisserie chicken across three rack positions.
You're replacing a coated toaster oven and hand-washing the accessories is an acceptable trade-off for uncoated surfaces.
The main thing to know
The borosilicate glass vessel is genuinely coating-free, but the crisper plate is ceramic nonstick — Ninja claims it's safe, and no independent lab has verified that. You're also paying $120 more than the base Crispi for a larger basket and extra cooking modes, not a safer cooking surface.
Every food-contact surface is bare stainless steel — no PTFE, no ceramic, no off-gassing risk at any temperature — but the air fry mode is underpowered at 53.6 watts per quart, and nothing in the box is dishwasher safe.
Skip this if you...
You need the crisper plate to be independently lab-verified PFAS-free — it's ceramic nonstick with brand-only safety claims, not third-party tested
Your household is 1-4 people and a 4qt basket is enough — the base Ninja Crispi has the same glass vessel for $120 less
You're price-sensitive — at $299.99, this is one of the most expensive air fryers on the market, and glass-vessel alternatives exist at a fraction of the cost
You need crispy results on dense proteins like chicken thighs — 53.6 W/qt can't sustain crisping temperature under a full load.
You expect dishwasher-safe accessories — the crumb tray, racks, and basket all require hand washing every time.
You want independently lab-tested PFAS-free certification — AB 1200 is a California regulatory disclosure, not a third-party verified result.
You're spending $245 and expect premium air frying performance — the wattage-to-capacity ratio doesn't match the price.
Neither of these quite what you're looking for?
I've reviewed all Air Fryer options at every price pointEvery Air Fryer in our database is scored using R3's V4.2 deterministic rubric — the same inputs always produce the same score. For this comparison, we evaluated Ninja and Our Place across 3 independent criteria: Safety (50%), Efficacy (25%), Usability (25%). No sponsored rankings. No paid placements.
Straight answers — no sponsored content, no filler.
The Ninja Crispi Pro 6-in-1 Glass Air Fryer uses a borosilicate glass basket with a ceramic nonstick crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the Ninja Crispi Pro 6-in-1 Glass Air Fryer (borosilicate glass basket, 7.8/10 safety) uses materials I'm more comfortable with at high heat. The Our Place Large Wonder Oven's stainless steel basket scored 7.8/10. In our V4.2 rubric, basket material accounts for a significant portion of the safety pillar, which carries 50% of the overall score.
For families, capacity comes first: Ninja offers 5.7-qt vs Our Place's 31.7-qt. Noise is worth checking too - Our Place runs quieter at 58dB. For cleanup, Ninja is dishwasher-safe. 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 V4.2 rubric, 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.
We use our V4.2 deterministic rubric with four weighted pillars: Safety (50%), Efficacy (20%), Usability (20%), and Value (10%). For air fryers, safety evaluates basket material composition, Prop 65 compliance, third-party certifications, and PFAS testing. Efficacy covers cooking performance, temperature accuracy, and capacity-to-wattage ratio. Usability scores noise levels, cleanup ease, and warranty terms. Every score is reproducible - the same product data produces the same score.
