Comparisons of the best air fryers are usually won by whichever has the largest number printed on the box, which is why so many kitchens contain a 10 quart machine used to reheat two portions of chips. Quoted capacity is the volume of the basket, not the area of its floor, and food only crisps in a single layer. A 6 quart basket that is wide and shallow cooks more in one go than a 10 quart one that is tall. For the other side of a training routine, our protein powder roundup compares blends, hydrolysate and bulk tubs on grams per scoop.
The machines themselves are not complicated. An air fryer is a small convection oven with a fan fast enough to move hot air around food in a perforated basket, which browns the surface the way a deep fryer does without the oil. What separates the seven below is the shape of the cooking space, whether it splits into two zones, what the basket is coated with, and how much of your worktop disappears permanently.
Best Air Fryers Compared on Capacity, Baskets and Footprint
Read capacity and layout together. Two baskets are only an advantage if you cook two things at once; if you usually cook one thing, a single large drawer gives you more usable floor area for the same money.
| Air fryer | Capacity | Layout | Top temperature | Best suited to |
|---|---|---|---|---|
| Breville Smart Oven Air Fryer Pro | 1 cubic foot interior | Countertop oven, 13 functions | Oven range with super convection | Replacing a second oven |
| Ninja French Door Premier FO101 | 20.3 quarts, 5 quart fry basket | French door oven, 10 functions | 450F cyclonic air | Family meals and whole roasts |
| Cosori TWINFRY | 9 quarts | Two 4.5 quart zones or one 9 quart | 6 functions | Households that want both layouts |
| Ninja DoubleStack XL SL401 | 10 quarts | Two stacked baskets, 4 levels | 6 functions | Two dishes where worktop is tight |
| Instant Pot Vortex Plus 6QT XL | 6 quarts | Single basket | 400F, from 95F | Most households, most of the time |
| Gourmia 10 Qt Dual Basket | 10 quarts, two 5 quart baskets | Two side-by-side drawers | 7 preset functions | Feeding a crowd on a budget |
| Chefman 2 Qt Mini | 2 quarts | Single square basket | 400F | One or two people, small kitchens |
Basket Coatings Are the Specification Nobody Reads
Almost every air fryer basket is nonstick, and until recently almost all of those coatings were made with fluorinated compounds. PFAS are a large family of synthetic chemicals the EPA now regulates in drinking water, and manufacturers have responded by moving to ceramic coatings and advertising the fact. The Cosori TWINFRY here states a PFAS-free ceramic coating on both the basket and the crisper plate, which is the specific wording to look for rather than the vaguer nonstick.
The practical difference day to day is smaller than the marketing suggests but not zero. Ceramic coatings tolerate higher temperatures and are less likely to degrade if a basket is run empty or scoured, which is what actually ruins a cheap nonstick finish within a year. If the coating in your current machine is flaking, that is the signal to replace it regardless of what the coating is made from.
The other health claim worth understanding is the opposite of the usual one. Air frying uses far less oil than deep frying, but browning starch at high heat produces acrylamide whichever method you use, and some research suggests air frying can produce more of it in certain foods than other methods. The mitigation is the same in any kitchen: cook potatoes and bread to golden rather than dark brown. The same applies to anything cooked hot and fast, including on a cast iron skillet.
1. Instant Pot Vortex Plus 6QT XL: The One Most Kitchens Should Buy
Six quarts in a single basket is the size that suits the largest number of households, and the Vortex Plus is the version of it with the fewest irritations. Six functions cover air fry, bake, roast, broil, dehydrate and reheat, the touchscreen shows which stage the cooking is at rather than just counting down, and there is little to no preheating.
The temperature range is the underrated part. It goes down to 95F as well as up to 400F, which is what makes the dehydrate setting genuinely usable for fruit and jerky rather than a label on a button. EvenCrisp is Instant Pot’s name for the airflow design, and the claim attached to it is 95 percent less oil than deep frying. For one to four people this is the machine to buy before considering anything larger.
What it does well
- Six quarts is the right size for most households.
- Temperature range from 95F to 400F makes dehydrating practical.
- Touchscreen shows the cooking stage rather than only a timer.
- Little to no preheating needed.
What to know before buying
- One basket, so no cooking two things at different settings.
- Stainless exterior marks easily with fingerprints.
- Tall basket shape limits single-layer floor area.
2. Cosori TWINFRY: Two Baskets or One, Decided by a Divider
The standing argument about dual basket air fryers is that you gain the ability to cook two things and lose the ability to cook one big thing. The TWINFRY settles it with a removable divider: leave it in for two 4.5 quart zones, take it out for a single 9 quart basket that fits a whole chicken.
That makes it the most flexible machine here for a household whose cooking varies. Sync finishes two different foods at the same moment and Match copies settings across both zones, which are the two features that make dual baskets worth having rather than merely present. The basket and crisper plate use a PFAS-free ceramic coating, which is a claim few competitors at this size make explicitly.
What it does well
- Removable divider converts two zones into one 9 quart basket.
- PFAS-free ceramic coating on both basket and crisper plate.
- Sync and Match handle two foods finishing together.
- Six functions covering air fry, roast, bake, broil, reheat and dry.
What to know before buying
- A 9 quart body takes serious worktop space.
- The divider is another part to store when not in use.
- Fewer preset programmes than the Gourmia.
3. Ninja DoubleStack XL: Two Zones Without the Width
Side-by-side dual basket air fryers are wide, and width is the dimension most kitchens cannot spare. Ninja stacked the baskets instead. The DoubleStack XL holds 10 quarts across two independently controlled zones, is about 40 percent slimmer than a conventional two-basket machine, and still fits under standard wall cabinets.
Each basket takes a removable meal rack, so you can cook on two levels per zone and run four foods at once. That is genuinely useful for a full meal, and it is also where the capacity claim needs reading carefully: four levels of food is four smaller single layers, not one large one. Smart Finish syncs two different foods to end together and Match Cook copies settings across both zones for a full 10 quart meal.
What it does well
- Stacked layout saves roughly 40 percent of the width.
- Two independently controlled zones, four cooking levels.
- Fits under standard wall cabinets.
- Smart Finish and Match Cook for two foods or one large batch.
What to know before buying
- Stacked baskets mean bending and lifting to reach the lower zone.
- Four levels are four small layers rather than one big one.
- Taller than it looks on a worktop with a low shelf above.
4. Ninja French Door Premier: An Oven That Air Fries Properly
At 20.3 quarts this stops being an air fryer and becomes a countertop oven, and that is the point. The included air fry basket holds 5 quarts and takes up to 5 pounds of chips, while the oven cavity itself takes a whole roast. French doors open together with one hand, which matters when the other hand is holding a tray.
Ten functions cover air fry, air roast, whole roast, bake, pizza, broil, reheat, dehydrate, toast and bagel. Ninja quotes a 90 second preheat and cooking up to 60 percent faster than a conventional oven, which is the real argument for a machine this size: it replaces turning on a full oven for a weeknight meal. Cyclonic air at 450F means bake, pizza and whole roast need no rotating partway through.
What it does well
- Largest usable capacity here, with a 5 quart dedicated fry basket.
- French doors open together with one hand.
- 90 second preheat and no rotating needed on the main functions.
- Ten functions including toast and bagel, so it replaces a toaster too.
What to know before buying
- Dominates a worktop and cannot be put away.
- Overkill for one or two people.
- More interior surfaces to clean than a basket machine.
5. Breville Smart Oven Air Fryer Pro: The Most Capable, at a Price
The Smart Oven Air Fryer Pro is the one machine here that would be worth owning even if it could not air fry. Five independent quartz elements are steered by the Element iQ system, which moves power to where it is needed, and digital PID temperature control eliminates the cold spots that make cheap countertop ovens bake unevenly.
Thirteen functions run from toast and bagel through pizza, proof, slow cook and dehydrate up to four trays at once. A two speed convection fan gives a super setting that Breville says cuts cooking time by up to 30 percent, and the 16 by 13.5 by 7 inch interior takes nine slices of bread, a 14 pound turkey or a 9 by 13 inch pan. For a household without a reliable main oven, this is a genuine replacement rather than a supplement.
What it does well
- Element iQ with five quartz elements and PID control for even heat.
- Thirteen functions including proof, slow cook and dehydrate.
- Takes a 14 pound turkey or a 9 by 13 inch pan.
- Two speed convection, with super convection cutting time up to 30 percent.
What to know before buying
- The most expensive machine in this guide by a wide margin.
- A large, heavy unit that is effectively permanent once placed.
- Air frying is one of thirteen jobs rather than the only one.
6. Gourmia 10 Qt Dual Basket: The Cheap Way to Feed a Crowd
If the requirement is two baskets and a large total capacity without a premium price, this is the machine. Ten quarts across two 5 quart drawers, seven one-touch preset functions, and Smart Finish to sync both baskets so everything lands on the table at the same time.
Match Cook duplicates settings across both drawers when you want the full capacity for one food, which is the other half of what makes a dual basket machine worth owning. FryForce 360 is Gourmia’s name for the airflow, and both baskets and crisper trays are dishwasher safe, which matters more than it sounds when there are two of everything to wash. What you give up against the Cosori is the removable divider and the stated PFAS-free coating.
What it does well
- Ten quarts across two independent 5 quart drawers.
- Smart Finish syncs both baskets to end together.
- Seven one-touch preset functions.
- Baskets and crisper trays are dishwasher safe.
What to know before buying
- No removable divider, so the two zones stay separate.
- The listing does not state a PFAS-free coating.
- A wide body that needs real worktop width.
7. Chefman 2 Qt Mini: The Right Size for One Person
Two quarts sounds useless until you count how often an air fryer is actually used to cook for one. The Chefman mini has a square basket, which uses its small volume better than a round one because the usable floor is the whole base rather than a circle inside a square. At the other extreme, party food in batches pairs with our guide to the best halloween costumes.
It reaches 400F, the same as machines three times the size, because top temperature is a function of the element rather than the capacity. A capacitive touchscreen sets time and temperature, a shake alarm sounds halfway through, and the basket and rack are dishwasher safe. The narrow body is designed to live on a worktop without dominating it, or to go in a cupboard between uses, which no other machine in this guide realistically does.
What it does well
- Square basket makes better use of a small capacity.
- Reaches 400F despite the size.
- Shake alarm partway through cooking.
- Small enough to store in a cupboard between uses.
What to know before buying
- Two quarts genuinely only feeds one or two people.
- No presets beyond manual time and temperature.
- Too small for a whole chicken or a full tray of chips.
How to Size an Air Fryer Without Guessing
Capacity in quarts describes the basket volume, and food crisps in a single layer, so the number that matters is floor area. A wide shallow basket beats a tall narrow one of the same quoted size every time. Work from the meal you cook most often rather than the largest one you can imagine.
- One or two people, cooking sides and snacks: 2 to 4 quarts.
- Two to four people, cooking a main: 5 to 6 quarts in a single basket.
- Four or more, or two dishes at once: 9 to 10 quarts split into two zones.
- Replacing an oven, or roasting whole birds: a countertop oven rather than a basket machine.
- Short on width rather than height: a stacked machine instead of a side-by-side one.
Measure the space before buying, including the gap above, because most of these need clearance for the hot air to vent and several are taller than the standard distance between a worktop and a wall cabinet. The machines that get used are the ones that live out permanently, which is the same reason a home espresso machine with a five minute warm-up gets used at weekends only. The same measuring job applies at floor level, which our guide to the best robot vacuums sets out before any suction figure. Frying also puts odours and fine particles into the room, which is what the carbon stages in our guide to the best air purifiers are for.
Which of These Air Fryers to Buy
For most households the Instant Pot Vortex Plus 6QT XL is the right answer: the correct size, a wide temperature range and nothing to go wrong. If you regularly cook two things at once, the Cosori TWINFRY is the better buy because the divider comes out and gives you a single 9 quart basket on the days you need one.
The Ninja DoubleStack XL is the pick when worktop width is the constraint rather than money. The Gourmia is the budget route to two baskets and ten quarts. At the top, the Ninja French Door Premier and the Breville Smart Oven Air Fryer Pro are countertop ovens that air fry rather than air fryers that bake, and either one can replace a second oven. The Chefman mini is the honest choice for one person, and it is the only machine here that will go back in a cupboard. Buy for the meal you cook on a Tuesday, not the one you cook at Christmas, and give it a permanent spot next to the kettle.
Frequently Asked Questions
Is a bigger air fryer always better?
No, and it is the most common buying mistake in the category. Quoted capacity measures basket volume while food crisps in a single layer, so a wide shallow basket cooks more at once than a taller one of the same quoted size. A larger machine also takes longer to heat and permanently occupies more worktop.
Are dual basket air fryers worth it?
Only if you genuinely cook two things at different temperatures. If you mostly cook one food, a single large basket gives more usable floor area for the money. The exception is a machine like the Cosori TWINFRY whose divider comes out, because that gives you both layouts in one body.
What does PFAS-free mean on an air fryer basket?
It means the nonstick coating is made without the fluorinated compounds that the EPA regulates in drinking water, usually by using a ceramic coating instead. Ceramic also tolerates higher temperatures and is less likely to degrade from scouring, which is what ruins most cheap nonstick baskets.
Do air fryers need preheating?
Most of these need little or none, which is a large part of their appeal against a conventional oven. The countertop ovens here quote a preheat of around 90 seconds, against ten minutes or more for a full oven, and that difference is what decides whether a machine gets used on a weeknight.
