The cooking bowl is tempered glass — no nonstick coating, no ceramic layer, nothing to chip or off-gas onto your food. Borosilicate confirmation isn't available, so let the glass cool 5–10 minutes before rinsing to avoid thermal shock. Under normal use, cracking risk is low.
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 crisper rack is stainless steel with no coating, so there's nothing to flake or degrade. Fritaire hasn't confirmed the alloy grade — most residential racks use 304 (18/8), which holds up well to acidic foods, but you can't verify that here. Contact the brand if grade confirmation matters to you.
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.
Fritaire claims PFAS-free, Teflon-free, and BPA-free, but no independent lab has verified this — no NSF cert, no Mamavation testing, no SGS report linked anywhere. At $199.99, you're taking the brand's word for it. If lab-verified PFAS-free claims matter, products like Cosori or Ninja with third-party certification exist at lower prices.
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.
At 260W per quart, this fryer handles chicken wings, fries, and vegetables without issue. Dense proteins like a thick pork chop will cook more evenly if you flip halfway through. That's a minor extra step, not a dealbreaker.
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.
400°F covers the vast majority of air fryer recipes — frozen foods, roasted vegetables, breaded chicken all cook well. You won't get deep steakhouse browning or heavy searing at this ceiling. If high-heat crisping is important to you, competitors like Typhur Dome 2 max out at 450°F.
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.
Five quarts works well for one to two adults per batch — a full chicken breast, a side of fries, or a small sheet of vegetables fits comfortably. If you're cooking for three or more, plan on multiple rounds. Fritaire doesn't publish interior bowl dimensions, so actual usable cooking area can't be confirmed.
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.
Every food-contact part goes straight in the dishwasher — glass bowl, rack, and lid. No scrubbing, no soaking, no exceptions. That matters more than it sounds: it's the difference between using this nightly and leaving it in a cabinet.
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.
At 55 dBA, this runs quieter than a normal conversation. You can watch TV at normal volume while it's going. Not suitable right next to a sleeping infant, but fine for an open-plan kitchen.
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.
Ninety days barely covers the return window at most retailers. If something fails at month four — a fan motor, a heating element — you're on your own. Pay with a credit card that offers purchase protection to extend your coverage.
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.
Everything you need to make the call — who each one is for, and who should skip it.
Go for it if you...
You want every food-contact surface to be coating-free — no PTFE, no ceramic, no nonstick layer anywhere.
You cook for one or two people and a 5qt capacity handles your typical meals.
You want to visually inspect the bowl mid-cook or confirm it's clean without guessing.
You prefer the self-cleaning mode (water, soap, hot air cycle) over scrubbing a basket by hand.
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
The main thing to know
The Fritaire is the only air fryer in this category with a tempered glass bowl and stainless steel rack — zero nonstick coating on any food-contact surface — but you're paying $199.99 for a 90-day warranty and a 400°F temperature ceiling.
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.
Skip this if you...
You need temperatures above 400°F — searing proteins or deep browning isn't achievable at this max.
You expect a standard warranty on a $200 appliance — 90 days is well below what most air fryers at this price offer.
You want the stainless steel grade disclosed — Fritaire doesn't specify the alloy, so you can't verify nickel content or food-grade certification.
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
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 Fritaire and Ninja across 3 independent criteria: Safety (50%), Efficacy (25%), Usability (25%). No sponsored rankings. No paid placements.
Straight answers — no sponsored content, no filler.
The Fritaire Non Toxic Air Fryer Pro, 9-in-1 Glass Air Fryer, Self-Cleaning uses a borosilicate glass basket with a stainless steel 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 Fritaire Non Toxic Air Fryer Pro, 9-in-1 Glass Air Fryer, Self-Cleaning's borosilicate glass basket scored 6.2/10. 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: Fritaire offers 5-qt vs Ninja's 5.7-qt. Noise is worth checking too - Fritaire runs quieter at 55dB. For cleanup, both are 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.
