• Kismile 5QT — best for small kitchens and one- or two-person meals; pick this if you want a compact 5QT glass basket with a digital touch panel, 8 presets and a 100–400°F range.
• Havato 5 — best for anyone who wants the cleanest possible cooking surface; pick this if an uncoated PTFE/PFAS-free borosilicate pot plus a stainless steel rack matters more to you than anything else.
• Generic 8-in-1 — best for tight countertops and smaller portions; pick this if a 4.2QT glass bowl with eight one-touch modes and a recipe book in the box suits how you cook.
• Fritaire Glass Air Fryer — best for whole-chicken roasts and low-effort cleanup; pick this if you want a rotisserie, a tumbling basket and a self-cleaning mode in a 5QT glass machine.
The Kismile is the straightforward glass air fryer: a 5QT glass basket, a white body, digital touch controls, and 1500W of heating. The basket is the headline. It's BPA-free, coating-free and chemical-free, which is the whole point of buying glass in the first place — you're not seasoning a nonstick layer, and you're not wondering what's flaking off into dinner.
In daily use, 5QT is a small-meal capacity. Think a portion of wings, a side of fries, roasted vegetables for two, or a reheat job. Kismile itself frames it for apartments, dorms and modern kitchens, and at roughly 13.2 by 11.2 by 9.96 inches it sits in that compact-countertop lane rather than dominating your workspace. The 11-pound weight is light enough to move when you need the counter back.
The controls are the part I'd actually live with every day. Eight presets, a 60-minute timer, and a 100–400°F range give you real flexibility — 400°F for crisping, lower settings for warming or gentler reheats. The basket and the detachable bottom tray are both dishwasher safe, and there's an oil-separating base to catch renderings. That last detail matters more than it sounds: with glass you can see the grease pooling, so you're not guessing.
The trade-off is capacity and the lack of accessories. There's no rotisserie, no rack mentioned in the box, and 5QT won't feed four people in one batch. If you cook for a family or want to roast a whole bird, this isn't the one. If you cook for one or two and want a clean, visible, easy-to-wash glass basket, it's a sensible pick.
Havato 5
The Havato takes the same basic shape — 5QT, glass, touch controls, 100–400°F, up to 60 minutes — and pushes the non-toxic angle harder than anything else here. The pot is high-borosilicate glass, uncoated, and explicitly free of PTFE and PFAS as well as BPA. It also ships with a 304 stainless steel grill rack, which is the detail I like most: food sits on steel, the bowl is glass, and there's no coating anywhere in the path.
Capacity is stated for two to four people, and Havato lists a whole 3 lb chicken, 1.5 lb of fries, or about 15 wings in one batch. The footprint claim is the interesting one: it stands under 11.5 inches tall, which is deliberately shorter than tower-style fryers that need clearance under upper cabinets. At 1550W it's the most powerful unit in this group, and the 5QT bowl is dishwasher safe along with the rack.
Two things to weigh. The heat-dissipation design and handle insulation are there specifically because glass gets hot — that's inherent to the material, not a flaw, but you handle this basket differently than a coated one. And there's no rotisserie or tumbling accessory, so whole-bird roasting is limited to what fits and sits on the rack. In my opinion, if "non toxic" is your primary filter, this is the one I'd point you to first.
This one is the compact option. It's a 4.2QT borosilicate glass bowl with a beige finish, 1200W of heating, and a body that measures about 14.1 by 11.2 by 11.7 inches — a space-saving countertop footprint aimed at small kitchens and apartments. The listing calls it "Large," but 4.2QT is the smallest capacity in this comparison, so read that as marketing rather than a spec.
The preset list is unusually specific: Reheat, Preheat, Wings, Fries, Steak, Seafood, Warm and Roast. That's eight one-touch modes covering the things people actually cook in an air fryer, plus adjustable temperature and timer for anything the presets don't cover. The 100–400°F range matches the others. You also get a stainless steel rack, a recipe book and a user manual in the box, which softens the learning curve if this is your first glass fryer.
The glass here is described as smooth and non-porous, which resists stains and odors — a real benefit with fish and anything heavily spiced, since glass doesn't hold onto last night's dinner the way a porous surface can. The basket is dishwasher safe, and the construction mixes borosilicate glass, silicone and stainless steel.
Fritaire Glass Air Fryer
The Fritaire is the most feature-loaded machine in this group, and it's the one to look at if you want glass but don't want to give up capability. It's a 5QT unit with a full 360° glass bowl, 1300W of convection, and a 400°F top temperature. The glass is BPA-, Teflon- and PFAS-free, so it meets the same non-toxic bar as the others while adding cooking modes they don't have.
The standout is the rotisserie and tumbling basket. You can roast a whole chicken on the skewer, or tumble fries and vegetables so they crisp evenly without you shaking the basket by hand. That hands-free tumbling is the feature I'd miss most going back to a plain glass drawer. It runs nine functions overall — air fry, bake, roast, broil, reheat, dehydrate and more — via one-touch presets, with a rotisserie skewer, rack and tumbler included. All the accessories are dishwasher safe; the glass bowl itself is not, so that part is a hand wash.
Then there's the self-cleaning mode, which is genuinely unusual. Add water and dish soap, press a button, and the unit scrubs itself. If the reason you're hesitant about an air fryer is the cleanup, this addresses it directly.
The trade-offs are real, though. It's the largest footprint here at roughly 10.8 by 13.9 by 12.6 inches, so measure your counter first. The voltage field on the spec sheet reads 60 volts, which doesn't match a standard North American 120V appliance and looks like a listing error — worth confirming with the seller before you buy. And note the material listing: the inner material is given as stainless steel rather than glass, so the "glass" refers to the bowl and outer construction. If you want rotisserie capability plus self-cleaning in a glass machine, I'd start here.
I compared published specifications and features only — basket material and coating claims, capacity, wattage, temperature range, controls, accessories and cleaning. The ranking is my independent editorial opinion, weighted toward how genuinely "non-toxic" each build is (uncoated glass, stainless steel contact surfaces) and then toward everyday usefulness. No brand paid for placement, and no product here was supplied for testing.
It depends on the basket, not the word "glass." The units here use borosilicate glass that is described as uncoated and free of BPA, PTFE and PFAS, which is what you want. If a glass fryer still uses a coated rack or nonstick insert, you've reintroduced the coating you were avoiding.
Glass is not nonstick in the slick sense, so food can stick more — a rack or a light oiling helps. In exchange you get full visibility, no coating to wear through, and no chemical odor as it heats. Glass also retains heat and stays hot after cooking, so handle it carefully.
Roughly 4 to 5 quarts covers one to four people depending on the food. The 4.2QT model here is the smallest and best for singles, couples or sides; the 5QT units fit more, with one listed as handling a 3 lb chicken, 1.5 lb of fries or about 15 wings in a single batch.
On the Kismile, Havato and Generic models, yes — the glass basket and tray or rack are listed as dishwasher safe. The Fritaire is the exception: its accessories are dishwasher safe but the glass bowl is not, so plan on hand washing that one.
