How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a multi-function countertop oven that can air fry, bake, broil and reheat with a roomy interior and simple dials, choose GreenLife Countertop Toaster Oven; if you need a dedicated, slim air fryer with digital presets and a big XL basket that tucks into tight kitchen space, choose BELLA Fits-anywhere Slim 4qt.
• GreenLife Countertop Toaster Oven — biggest strength: A true countertop oven that air fries, bakes, broils and reheats, with dual heating elements, a clear viewing window and a PFAS-free ceramic nonstick pan and basket included.
• GreenLife — biggest trade-off: It's a manual, dial-controlled oven rather than a digital preset machine, and its capacity is built around 4 slices of bread or a 9" pizza, not giant batches of fries.
• BELLA Fits-anywhere Slim 4qt — biggest strength: A narrow, tall footprint with a 4-qt XL basket (up to 3.3 lbs of food), 1300 watts of circular heat and 6 digital presets including dehydrate, at temperatures from 90 °F to 400 °F.
• BELLA — biggest trade-off: It's a single-purpose air fryer with a nonstick coated basket, not a full oven, so it won't toast four slices of bread or bake a 9" pizza.
• Who GreenLife is for: Anyone cooking for one who wants one appliance that also handles toast, small bakes and reheats with zero digital fuss.
• Who BELLA is for: A single cook who wants fast, crispy air-fried portions and dehydrating in a slim unit that barely takes up counter width.
The GreenLife Countertop Toaster Oven is, at heart, a small oven that happens to air fry well. Two powerful heating elements sit behind a stainless steel dropdown door, and the adjustable time and temperature dials let you set a cook and walk away. There's no preset menu to learn, no touch panel to tap through, no manual to consult — you turn two knobs and you're cooking. For a one-person kitchen, that simplicity is the whole appeal.
Where it earns its place is flexibility. The generous interior fits 4 slices of bread or a 9" pizza, so it's genuinely useful for a single person's toast-and-leftovers routine, not just frying. It air fries with little to no oil, bakes, broils and reheats, and it ships with a PFAS-free ceramic nonstick baking pan and a PFAS-free air fry basket, so you're not buying trays separately. The large heat-resistant window means you can watch food without opening the door and dumping heat. At roughly 6 pounds and about 12.28"D x 14.29"W x 7.95"H, it's compact and easy to slide into a cabinet or a corner.
Who should buy it: the solo cook who wants one appliance to air fry a chicken breast, toast breakfast, reheat last night's dinner and broil a small piece of fish — and who prefers knobs over a digital display. Who should skip it: someone who mainly wants big batches of fries in one pull, or who wants one-touch presets and precise digital temperature setting. In my opinion, this is the better pick if your "air fryer" is really your second oven.
The BELLA Fits-anywhere Slim 4qt is built around one idea: fit where other air fryers won't. Its dimensions are 14.56"D x 8.22"W x 11.14"H — notice how narrow that width is. It's tall and shallow rather than wide, which is exactly what you want on a cramped counter or a narrow shelf. BELLA claims the design saves up to 50% more space compared to prior models, and the footprint backs that up.
It's also the more automated of the two. Touch controls drive 6 presets — air fry, bake, roast, broil, reheat and dehydrate — with temperature adjustable from 90 °F up to 400 °F. The 1300 watts and circular heat technology are there to push hot air around the basket for even crisping. The XL basket holds up to 3.3 lbs of food, so a family-size batch of fries or chicken fits in one go, and the EverGood ceramic nonstick coating is made without PFAS, PTFE, PFOA, lead or cadmium, which makes cleanup a wipe rather than a scrub. It weighs 7.3 pounds.
Who should buy it: a single person who wants fast, crispy portions with one-touch presets, and who may want to dehydrate — jerky, fruit, herbs — which the GreenLife doesn't offer. The narrow width is a real advantage in a small apartment. Who should skip it: anyone who needs an actual oven. It won't toast four slices at once or bake a 9" pizza, and if you want to bake a small cake or broil a full tray, you'll miss the GreenLife's oven cavity.
Side-by-Side: Which Should You Choose?
• Best for tight counter width → BELLA Fits-anywhere Slim 4qt. At 8.22" wide it's the slimmer of the two by a wide margin.
• Best for big single-batch air frying → BELLA. The 4-qt basket holds up to 3.3 lbs, versus the GreenLife's 4-slice / 9"-pizza interior.
• Best for preset-driven, hands-off cooking → BELLA. Six touch presets, including dehydrate, plus 90–400 °F temperature control.
• Best for dial-simple, no-menu cooking → GreenLife. Two knobs, adjustable time and temp, nothing to program.
• Best for watching food cook → GreenLife. The large heat-resistant window lets you monitor without opening the door; the BELLA is a closed basket.
• Best for dehydrating → BELLA. It's the only one of the two with a dehydrate function.
• Best for a "one appliance does everything" kitchen → GreenLife. Toast, reheat, bake and broil all live in the same box.
• Best for ceramic nonstick included accessories → GreenLife. It ships with a PFAS-free ceramic pan and basket, so you're ready to cook out of the box.
For one person, I'd buy the GreenLife Countertop Toaster Oven. Here's my reasoning: a single cook rarely needs a dedicated fryer — they need one appliance that toasts, reheats, bakes and air fries without juggling three gadgets on a small counter. The dials, the viewing window, the included nonstick pan and basket, and the 4-slice / 9"-pizza interior all point to a machine that earns its footprint every day. I'd pick the BELLA only if counter width is genuinely tight or if dehydrating and one-touch presets matter more to me than oven-style versatility. Both are solid; for the "best air fryer for one person" job, GreenLife wins on range of use.
Both. It air fries with little to no oil using dual heating elements, and it also bakes, broils and reheats in an oven interior that fits 4 slices of bread or a 9" pizza.
Yes. It has 6 touch presets — air fry, bake, roast, broil, reheat and dehydrate — with adjustable temperature from 90 °F to 400 °F and 1300 watts of power.
For narrow counters, the BELLA is slimmer at 8.22" wide, and BELLA states the design saves up to 50% more space than prior models. The GreenLife is shorter and more oven-shaped at about 14.29"W x 7.95"H, which can tuck under cabinets more easily.
Both use PFAS-free ceramic nonstick. GreenLife includes a PFAS-free ceramic baking pan and air fry basket; BELLA's EverGood ceramic coating is made without PFAS, PTFE, PFOA, lead or cadmium. For current pricing on either, check the latest price on Amazon using the button on this page.
