The Ninja Crispi went viral because it has a glass bowl. So every review online stops there. But a glass bowl does not make an air fryer non-toxic. Food sits on a metal crisper plate with a coating most reviewers never even name. So this review evaluates the Crispi against the four things that actually matter for an air fryer — PTFE, PFAS, BPA, and the chemistry of “ceramic” non-stick coatings — using every official Ninja document, three-country support FAQs, retailer Q&As with SharkNinja Product Experts, and independent material analyses. Here is the answer, sourced line by line.
The Four-Pillar Framework for a Non-Toxic Air Fryer
“Non-toxic” has no legal definition for cookware. So before scoring the Crispi, here is the rubric every air fryer on this site runs through.
1. PTFE. The chemical name for Teflon. It is a non-stick coating that releases fumes above 500°F. The fumes can kill pet birds in minutes. The flu-like symptoms in humans are documented and have a name — polymer fume fever. Most coated air fryer baskets are PTFE.
2. PFAS. The broader chemical family Teflon belongs to. The “forever chemicals.” They do not break down in the body or the environment. PFAS shows up in non-stick coatings, water-repellent fabrics, and food packaging. A product can be Teflon-free and still contain other PFAS. So the distinction matters — which is exactly why we built The Fair Marrow Standard to separate the two.
3. BPA. A plasticizer that mimics estrogen. Most modern appliances claim BPA-free for food-contact plastics. The replacements (BPS, BPF) have similar issues, which is why BPA-free is necessary but not sufficient.
4. Heavy metals in ceramic coatings. Not all ceramic is the same. Real ceramic is fired clay. “Ceramic non-stick” coatings are usually sol-gel — a sprayed mix of silica, metals, and binders that gets called ceramic for marketing. Some are clean. Some are not. The brand’s transparency is the only signal you have.
That is the standard. Now the Crispi.
The Ninja Crispi’s Materials, Component by Component
One quick correction before we start. The Ninja Crispi is model FN101. The Pro is AS101. You will see SF301 floating around online — that is the Ninja Speedi, a different appliance entirely. The Amazon listing under ASIN B0D2Y6SRKY is the FN101 Crispi. We checked.
The Glass Bowl
The glass containers are borosilicate. Ninja Canada’s official FAQ states it plainly: “Containers: Borosilicate glass with BPA free plastic handles.” A SharkNinja Product Expert confirmed the same on Best Buy’s Q&A.
Borosilicate is what Pyrex was originally made from. It is genuinely inert. No coatings. Nothing leaches. This part of the Crispi is non-toxic with no asterisks. Say it cleanly: the glass is fine.
The Crisper Plate (This Is the Linchpin)
The crisper plate is what your food actually sits on. So this is the question that matters most. And it is the one nobody else answers.
Per Ninja’s own FAQ: “Crisper plates: Aluminum with a nano-ceramic coating.” So the substrate is aluminum. The non-stick layer is nano-ceramic.
And here is the strongest official statement Ninja has made anywhere. From the SharkNinja Canada product page: “All food-contact surfaces are designed without PFAS and PTFE. We work with independent third-party labs to ensure compliance with global regulations and safety standards.” A SharkNinja Product Expert said the same thing on Target’s Q&A: “completely PTFE free. All food contact surfaces are made without PTFE or PFAS.”
So the crisper plate is not Teflon. That is settled. RTINGS, the third-party hardware lab, also lists the coating as ceramic.
And here is the honest part. “Nano-ceramic” is a marketing term. The actual material is what materials scientists call a sol-gel quasi-ceramic — a sprayed mix of silica, metals, and binders. Prudent Reviews has a clean breakdown of what that actually means. Ninja does not publish the exact formula because cookware coating chemistry is shielded under trade secret laws. So is every competitor’s. There is no legal definition for “ceramic” or “non-toxic” in cookware, full stop.
So what we have, sourced and confirmed: aluminum substrate, nano-ceramic coating, no PFAS, no PTFE, no Teflon. What we do not have: the exact ingredient list of the coating. That is the trade-off you are accepting if you buy this. If that gap is unacceptable to you, there is a workaround. Aftermarket stainless steel racks fit the standard FN101 Crispi. They do not fit the Pro because of its sloped walls.
The Lids and Plastic Components
Storage lids are BPA-free plastic. Container handles are BPA-free plastic. The container adapter is BPA-free plastic and metal. All of that is in Ninja’s FAQ. The SharkNinja press release repeats the BPA-free claim for the lids.
One gap. The PowerPod itself — the heating unit — has a plastic shell. Ninja does not publicly disclose the exact polymer grade of that shell. It is also not a food-contact surface. The lids, handles, and adapter are. So the food-contact plastic is BPA-free and well-documented. The housing plastic grade is undocumented.
The Heating Element
The heating coil is exposed on the bottom of the PowerPod. Ninja does not specify the wire composition in any official document we could find. Air fryer heating elements in this category are typically nichrome or stainless steel resistance wire, both of which are inert. We can say “typically.” We cannot say “confirmed for the Crispi.” Material undisclosed.
Operating Temperature
Max is 450°F per RTINGS measurements and Ninja’s own spec. PTFE starts breaking down at 500°F. So even if the Crispi had used Teflon, it would not hit the degradation threshold. It does not use Teflon, so the point is academic. But useful to know.
Ninja Crispi vs. Ninja Crispi Pro — Does the Upgrade Change the Non-Toxic Picture?
Short answer: no. The non-toxic story is identical.
Both models use borosilicate glass containers with BPA-free plastic handles. Both use the same aluminum-plus-nano-ceramic crisper plate. Both are PFAS-free and PTFE-free per the same official statements. Both top out at 450°F. Target’s Q&A with a SharkNinja Product Expert spells it out for the Pro: “borosilicate glass containers with BPA free handles, aluminum crisper plates with a PFAS free nano ceramic coating, and BPA free plastic lids.”
What is different: the Pro has a stainless steel modular base instead of a plastic adapter. It also adds Roast and Dehydrate functions, runs at 1,800W instead of 1,500W, and is countertop-fixed rather than portable. The Pro’s containers are larger — 6 quart and 2.5 quart — versus the standard’s 4 quart and 6 cup.
If your decision is purely about non-toxic materials, the Pro buys you nothing. If you want more capacity and a stainless steel base, the Pro is worth the upgrade. If you want the option to swap in a stainless steel rack and skip the ceramic coating entirely, buy the standard FN101 — those aftermarket racks do not fit the Pro.
Honest Verdict — Is the Ninja Crispi Non-Toxic?
Yes, with one caveat we are going to be transparent about. Here is the breakdown.
What passes our standard:
- Borosilicate glass containers — inert, no coatings, confirmed
- BPA-free lids, handles, and adapter — confirmed by Ninja FAQ
- No PTFE, no PFAS on any food-contact surface — confirmed by Ninja Canada and SharkNinja Product Experts on Best Buy and Target
- Max temperature 450°F — well below any coating-degradation threshold
- Same materials in the Pro version
The honest caveat:
The crisper plate’s nano-ceramic coating is a proprietary sol-gel formula. Ninja does not publish the exact ingredient list. Nobody in cookware does — coating chemistry is trade-secret protected across the industry. Ninja’s claim that the coating contains no PFAS or PTFE is consistent with their official documentation in three countries and with their direct responses on retail Q&A. It is the strongest disclosure available short of a full chemical assay.
If a proprietary coating is a dealbreaker for you, the Crispi is not your air fryer. Buy the Fritaire or the Wonder Oven instead — both keep food on uncoated stainless steel. Or buy the standard Crispi and add an aftermarket stainless steel rack. We list the alternatives below.
For everyone else, the Ninja Crispi clears our standard. It is the cleanest air fryer ever shipped by a major mass-market brand. The marketing oversells the glass and underplays the ceramic plate, which is annoying. The materials themselves are solid. So if you are looking for the safest air fryer or the healthiest air fryer in mass-market retail, the Crispi is the strongest option we have tested.

| Ninja Crispi Pro (AS101) | Borosilicate glass + nano-ceramic-coated aluminum plate | PFAS-free, PTFE-free (proprietary coating) | 450°F | $230 |
| Our Place Wonder Oven | Stainless steel chamber + chromed steel basket; bake pan has ceramic non-stick | PFAS-free across all surfaces; AB1200 disclosed | 450°F | $185 standard / $199–$279 Pro |
| Fritaire Self-Cleaning | Tempered glass bowl + 304 stainless steel accessories (no coating) | PFAS-free, PTFE-free, no non-stick at all | 400°F | $200 |
| Cosori Iconic | Stainless steel exterior + PFAS-free ceramic-coated aluminum basket | PFAS-free, PTFE-free (proprietary ceramic coating) | 450°F | $249 |
Our Place Wonder Oven
The Wonder Oven is the most transparent option in the category. Stainless steel oven body. Chromed steel air fryer basket. Stainless steel crumb tray. The bake pan is the only piece with a coating, and Our Place discloses it as a “toxin-free non-stick ceramic” — the same sol-gel ambiguity as Ninja, but on an accessory rather than the primary cooking surface. Our Place is also California AB1200 compliant with full chemical disclosures. About $185 for the standard, $199 to $279 for the Pro depending on size. Sold direct, at Crate and Barrel, Target, Williams Sonoma.
Fritaire Self-Cleaning Glass Air Fryer
If you want zero coating on any food-contact surface, this is the cleanest option we found. The Fritaire uses a tempered glass cooking bowl with 304 stainless steel accessories — rotisserie, tumbling basket, air stand. No ceramic plate. No coating. Food contacts glass and stainless steel only. The brand also openly discloses that one internal component is food-grade PPS plastic rated to 500°F, which is a level of transparency Ninja does not match. Trade-offs: max temperature is 400°F (lower than the Crispi’s 450°F), the glass is tempered rather than borosilicate, and capacity is 5 quarts. About $200 at Fritaire.com or Home Depot.
Cosori Iconic (Stainless Steel Build)
If you want a more traditional air fryer form factor with a stainless steel body, the Cosori Iconic is what the toxicologists at Homes and Gardens and the editors at CNET point to. Stainless steel structure, 96% metal by visible area, PFAS-free ceramic-coated basket, BPA-free, 450°F max, 6.5-quart capacity, five-year warranty. Honest precision: the basket coating is the same category of PFAS-free sol-gel ceramic as the Ninja. The “stainless steel” refers to the exterior. About $249 at Best Buy or Cosori.com.
FAQ
Is the Ninja Crispi PFAS-free?
Yes. SharkNinja’s official statement on the Canadian product page confirms all food-contact surfaces are designed without PFAS and PTFE — glass containers, BPA-free lids and handles, and the aluminum crisper plate with its nano-ceramic coating. Ninja’s US marketing only emphasizes the glassware, which has caused confusion.
Is the Ninja Crispi BPA-free?
Yes for every food-contact plastic. Ninja’s official FAQ confirms storage lids, container handles, and the adapter are BPA-free, and the glass itself contains none. The PowerPod’s outer shell is not food-contact, so Ninja does not publish a BPA claim for it.
What are the disadvantages of the Ninja Crispi?
A few. The 64-square-inch cooking surface is small, there is no manual temperature control (only presets starting at 375°F), exposed heating coils sit two inches off the counter when set down, replacement glass runs $44 to $60, and the Pro is loud at 67 dBA.
Is the Ninja Crispi the same as an air fryer?
Yes, technically. It uses 1,500W convection air circulation, which is the definition. But the cooking vessel is a borosilicate glass container instead of a coated aluminum basket, and the detachable PowerPod snaps onto different container sizes so the same vessel cooks, stores, and serves.
Is the Ninja Crispi better than the Ninja Foodi?
For non-toxic materials and easy cleaning, the Crispi wins. But for multi-function cooking, the Foodi wins because it pressure cooks, slow cooks, and steams in addition to air frying. So pick based on what you actually cook, not the spec sheet.
What is so special about the Ninja Crispi?
It is the first major-brand air fryer to use borosilicate glass chambers instead of coated aluminum baskets — you prep, cook, serve, and store in the same container. So the materials story is meaningfully cleaner than every coated-basket competitor, provided you accept the crisper plate’s proprietary nano-ceramic coating.
One sentence verdict: the Ninja Crispi clears the Fair Marrow non-toxic standard with one honest caveat about the proprietary nano-ceramic coating, and it is currently the cleanest mass-market air fryer money can buy. Check current price on Amazon →
