• Oster Compact Countertop Oven — best for small kitchens that want air frying plus real oven functions; pick this if you want five cooking modes, three rack positions, and a 60-minute timer in a 12.4-pound unit that fits a 9-inch pizza.
• Ninja ® Combi™ All-in-One — best for feeding a crowd from one machine; pick this if you need 14 functions, family-sized capacity for up to 8 people, and combi cooking that steams and crisps at the same time.
• Tovolo Stainless Steel Tongs — best for handling hot food in and out of an air fryer basket; pick this if you want silicone-tipped tongs rated to 600°F that won't scratch nonstick coatings.
• GreenLife Countertop Toaster Oven — best for a compact, PFAS-free setup; pick this if you want a ceramic nonstick pan and air fry basket included, with a clear window for watching your food.
This is a countertop oven first and an air fryer second, and that combination is exactly why I recommend it. Oster built a single stainless steel box that covers air fry, bake, adjustable broil, toast and warm. The body, door and finish are all stainless steel with a brushed look, so it reads as a proper appliance rather than a plastic gadget on your counter.
In daily use, the independent dials matter more than they sound. Temperature, function and timer each get their own knob, which means you set the mode you want without paging through a menu. There are three rack positions and a 60-minute timer, and the adjustable broil lets you broil at whatever temperature you choose instead of a single fixed setting. Turbo Convection Technology is the part that does the heavy lifting here — it circulates heat so food cooks faster and browns more evenly than a conventional oven would.
The air fry claim is the headline: Oster states you can make fried favorites with 99.5% less oil compared to 3.7L deep fryers. That comparison matters, because it tells you the reference point is a full-size deep fryer, not a splash of oil in a pan. Vegetables come out as crunchy snacks rather than soggy ones, and that alone justifies the counter space for a lot of people.
Ninja ® Combi™ All-in-One
The Ninja Combi is a different animal entirely. Where the Oster is a small oven with air frying built in, this is a countertop multicooker that happens to air fry. The function list runs to fourteen: Combi Meals, Combi Crisp, Combi Bake, Rice/Pasta, Sear/Sauté, Steam, Bake, Toast, Pizza, Slow Cook, Proof, Sous Vide, Air Fry and Broil. That's a lot of jobs in one stainless steel and grey unit with a dropdown door.
The technology behind the name is HyperSteam plus Air Fry working at once. Super-heated steam cooks the food through and keeps it juicy while rapid cyclonic air crisps the outside. In practice that means you get the texture of fried food without the two-step process of cooking then crisping. Ninja also states you can go from frozen to table in under 30 minutes, because the steam thaws and cooks frozen ingredients directly rather than making you defrost first.
Capacity is the real selling point. Ninja says it feeds up to 8 people and fits 1.5 boxes (24 oz) of pasta, 4 cups of dry rice, a 6-pound roast chicken, 2 pounds of fries, a 10-inch pizza or a 5-pound top round roast. It also claims complete meals cook in about 15 minutes, roughly 50% faster than a wall oven. If you're cooking for a household or entertaining, those numbers are the difference between one appliance doing the work of several and you still reaching for the oven.
The trade-off is footprint and complexity. At 14.92 by 15.43 by 13.11 inches and 20.2 pounds, it takes up more counter than the Oster, and fourteen functions mean a learning curve — you'll lean on the included recipe book and cooking charts at first. Cleanup is easier than you'd expect, since the Combi Cooker Pan doubles as a serving dish and the accessories are dishwasher safe. In my opinion this is the pick for anyone who wants one machine to replace a slow cooker, steamer, rice cooker and air fryer at once, and who has the counter to spare.
Tovolo Stainless Steel Tongs
Not every stainless steel air fryer purchase is a big one, and this set solves a problem nobody thinks about until they burn their fingers: getting food out of a hot basket. You get three tongs — two at 9 inches for medium portions and one at 12 inches for larger items — so you're not using the same tool to flip a shrimp and lift a whole chicken.
Two small details earn their place. The easy-lock mechanism keeps them closed and compact in a drawer, and they're dishwasher safe, so cleanup is a non-issue. The color is listed as assorted, and the set is three pieces.
The trade-off is simple: this is a tool, not an appliance. If you already own tongs you like, you don't need these. If your current pair is flimsy, scratched, or too short to reach into a deep air fryer basket safely, this set is the practical add-on I'd suggest alongside whichever oven you choose.
GreenLife's take is the smallest and lightest of the group, and it leans hard into the nonstick story. The unit is 12.28 by 14.29 by 7.95 inches and weighs 6.3 pounds — noticeably more compact than the Oster, with a painted stainless steel door and a pink body finish.
Inside, you get a PFAS-free ceramic nonstick baking pan and a PFAS-free air fry basket, both included. That's the differentiator. If you're trying to move away from coated cookware you're unsure about, GreenLife is explicitly building the air fryer around that concern. Dual heating technology uses two elements for faster, more even cooking, and the air fry mode is designed to give you crispy, golden results with little to no oil.
Controls are two dials — adjustable time and temperature — which keeps things simple. A large heat-resistant window lets you watch your food without opening the door and losing heat, and auto shutoff is there for safety. Capacity fits four slices of bread or a 9-inch pizza, the same practical range as the Oster. The included accessories are the oven, removable air fry basket, baking pan and rack.
The main trade-off is scale and scope. It's the least versatile of the ovens here — no broil functions list, no convection branding, no multi-cooker modes — and the small interior limits you to small-batch cooking. In my opinion it's the right pick for a single person, a couple, or a dorm and small-apartment kitchen where PFAS-free materials and a genuinely small footprint matter more than cooking a whole meal at once.
We compared published specifications and feature sets — cooking modes, capacity, materials, controls, dimensions and included accessories — for stainless steel air fryers and air fryer accessories. The order above reflects our independent editorial judgment about which product fits which kind of cook, not a ranking of quality. No brand paid for placement or had any input into these picks.
Stainless steel construction is chosen for durability and appearance, and it's what you'll find on the Oster, Ninja and GreenLife ovens here. It doesn't change how the air frying works — that comes from the heating elements and fan — but it does affect how the appliance looks and holds up over time.
The Oster and GreenLife both fit a 9-inch pizza or about four slices of bread, which suits one or two people. The Ninja Combi is the family-sized option, with capacity for up to 8 people, a 10-inch pizza, 2 pounds of fries or a 6-pound roast chicken.
You don't need them, but silicone-tipped tongs help. They protect nonstick baskets from scratches and the 12-inch length keeps your hands away from hot surfaces. Tovolo rates its set to 600°F, which covers anything you'll do in an air fryer.
For small-batch cooking, yes — the Ninja Combi comes closest, with 14 functions and combi cooking that Ninja says makes complete meals in about 15 minutes. For large roasts or big baking projects, you'll still want a wall oven.
