Quick answer: The best glass air fryer for most people is the Ninja Crispi Pro, whose listing says all its food-contact surfaces are free of forever chemicals. The original Ninja Crispi is the smaller, most-reviewed option, and the Cuisinart glass basket air fryer is the pick if you want a classic pull-out drawer. One catch we found: in 14 glass air fryers we checked, only 6 said the crisper plate or rack inside the glass is PFAS-free too.

Key Findings: 14 Glass Air Fryers
- 6 of 14 glass air fryers say every food-contact part, including the crisper plate or rack, is PFAS-free or uncoated.
- 4 of 14 make the PFAS claim only about the glass container and say nothing about the plate or tray inside it.
- 4 of 14 make no PFAS claim at all, and two of those mention a “coating” or a nonstick tray.
- Ninja makes 4 of the 14, and its original Crispi has more than 7,000 reviews, far more than any other glass model we found.
The Data: What Touches Your Food in Each One
We searched the largest US online store for glass air fryers and recorded what each listing says about the glass and about the plate, rack or tray that sits inside it.
| Air fryer (as listed) | Glass | What the listing says about parts inside |
|---|---|---|
| Ninja Crispi Pro | Borosilicate | “All food-contact surfaces” free of forever chemicals |
| Ninja Crispi Microwave & Air Fryer | CleanCrisp glass | Glassware and crisper plate “100% PFAS, PTFE, and PFOA free” |
| Cuisinart Glass Basket 4 Qt | Borosilicate | Glass basket and nonstick crisper plate “both PFAS-free” |
| Chefman Crisp n’ Go 4 Qt | Glass | Glass bowl and crisper rack PFAS-free |
| 5 QT Glass Air Fryer (unbranded) | Borosilicate | Uncoated glass and a 304 stainless steel rack |
| WILLOW Eco Series 5 Qt | Tempered glass | Whole fryer “free of PTFE, PFOA, PFAS, BPA, and Teflon” |
| Ninja Crispi (original) | Borosilicate | Claim covers the glass containers |
| Ninja Crispi DualZone | CleanCrisp glass | Claim covers the glassware; crisper plates not addressed |
| Kismile 5 QT | Glass | Glass basket “coating-free”; bottom tray not addressed |
| Kismile AeroLucen 5 QT | Borosilicate | Glass barrel PFAS-free; inner parts not addressed |
| Fritaire 9-in-1 Pro | Glass | Stainless steel rotisserie and basket; no PFAS claim |
| BOSWELL 7.5 QT | Glass | Mentions a “non-toxic coating”; no PFAS claim |
| NutriChef 8.5 QT Dual | Glass | No PFAS or coating claim |
| Nutrichef 5.8 QT | Transparent bowl | Nonstick tray; no PFAS claim |
Why it matters: if the glass is coating-free but the plate your food sits on is a nonstick coating, the “glass” part only solves half the problem. A missing claim doesn’t prove a plate is coated. It means you can’t tell from the listing.

Best Overall: Ninja Crispi Pro
The Ninja Crispi Pro comes with a 6-quart and a 2.5-quart CleanCrisp borosilicate glass container, each with a crisper plate and a snap-lock storage lid. Its listing says the containers are “100% free from forever chemicals on all food-contact surfaces,” the broadest claim among the Ninja models. The base also fits a 4-quart container, and the listing says the glass is thermal-shock resistant, so you can go from freezer to air fryer.

Best Compact: Ninja Crispi
The original Ninja Crispi is the glass air fryer most people have heard of, with more than 7,000 reviews. A small “PowerPod” heater sits on top of a 4-quart or a 6-cup borosilicate glass container. Ninja says the containers are “free of PFAS, PTFE, and nonstick chemical coatings,” and you can cook, serve and store leftovers in the same dish. CNET named it its top nontoxic pick after testing 20 air fryers.

The Ninja Crispi DualZone is a countertop unit with two independent 4-quart glass containers (8 quarts total), so you can cook two foods at different settings and have them finish together. The listing says the glassware has “no PFAS or PTFE” and is thermal-shock resistant. It doesn’t make a separate claim about the crisper plates.

Best Microwave Combo: Ninja Crispi Microwave and Air Fryer
Short on counter space? The Ninja Crispi Microwave and Air Fryer combines both in one 14-in-1 unit. Its listing makes one of the clearest claims we found: the glassware and crisper plate are “100% PFAS, PTFE, and PFOA free.”

Best Budget: WILLOW Eco Series
The WILLOW Eco Series is a 5-quart drawer-style fryer with a tempered glass basket. Its listing says the fryer is “completely free of PTFE, PFOA, PFAS, BPA, and Teflon.” It has fewer reviews than the Ninja models, so it’s a newer, less proven option.

How to Use a Glass Air Fryer Safely
- Follow the maker’s limits for temperature and for going from fridge or freezer to hot.
- Don’t put a hot bowl on a wet or cold surface. Sudden temperature changes are the usual cause of cracked glass.
- Stop using a chipped or cracked bowl. Check the rim and base before each use.
- Use the heat-safe feet or a trivet as the maker recommends.
Why avoid PFAS at all? Minnesota has banned the sale of cookware with intentionally added PFAS since January 1, 2025, under a law whose definition covers Teflon-type coatings. Our Kitchen Truth Bible covers what’s in your kitchen in more depth.

Frequently Asked Questions
Are glass air fryers non-toxic?
The glass bowl itself has no coating, so there’s nothing to peel off. But check what sits inside it: in our check of 14 glass air fryers, only 6 said the crisper plate or rack was PFAS-free too. Look for a claim that covers all food-contact parts.
What is the best glass air fryer?
For most people, the Ninja Crispi Pro. Its listing says its glass containers are free of forever chemicals “on all food-contact surfaces,” and it comes with a 6-quart and a 2.5-quart container. The original Ninja Crispi is the smaller, most-reviewed option.
Is a glass air fryer better than a regular one?
It’s better if you want to avoid nonstick coatings and see your food cook. A regular basket air fryer is usually lighter and more common. Several glass models in our check also had smaller capacities than family basket air fryers.
Can glass air fryers shatter?
Any glass can break if dropped or hit. Ninja says its CleanCrisp glass is thermal-shock resistant, but follow each maker’s instructions, avoid putting a hot bowl on a wet or cold surface, and stop using a bowl that’s chipped or cracked.
Do glass air fryers cook as well as basket air fryers?
We didn’t test cooking performance ourselves. Food Network and CNET have both reviewed the Ninja Crispi favorably, and CNET named it its top nontoxic pick after testing 20 air fryers.
Is the Ninja Crispi PFAS-free?
Ninja’s listing says the Crispi’s CleanCrisp borosilicate glass containers are free of PFAS, PTFE and nonstick chemical coatings. The Crispi Pro listing goes further and says all food-contact surfaces are free of forever chemicals.
