An air fryer is a small convection oven with a fan fast enough to matter. There is no frying involved, and the marketing around “healthy” versions of fried food is mostly noise. What the appliance genuinely does well is cook small quantities quickly without heating a full-size oven, and produce a dry, crisp surface that a microwave never will.
The seven below cover the four shapes this appliance actually comes in: single basket, dual basket, toaster-oven style and pod. The shape matters far more than the brand, because it decides what fits and what you can cook at once.

The Seven Compared
Capacity in quarts is the basket volume, not how much food fits flat. Air frying needs airflow around the food, so a 6-quart basket holds roughly two portions in a single layer rather than six quarts of chips.
| Model | Type | Capacity | Max temperature |
|---|---|---|---|
| Cosori TurboBlaze | Single basket | 6 qt | 450F |
| Ninja Air Fryer Pro AF142 | Single basket | 5 qt | 400F |
| Ninja Foodi DualZone DZ302 | Dual basket | 10 qt total | Not stated |
| Chefman TurboFry | Single basket | 8 qt | 450F |
| Cuisinart Air Fryer Toaster Oven | Toaster oven | 0.6 cu ft | Not stated |
| bella Fits-Anywhere Slim | Single basket, slim | 6 qt | Not stated |
| Ninja Crispi | Pod and glass containers | 4 qt and 6 cup | 450F |
1. Cosori TurboBlaze: The Fastest Fan and a PFAS-Free Basket
Two specifications separate this from the crowd, and both are unusual to see published. The fan runs at 3,600 rpm with five selectable speeds, and the temperature range runs from 90F all the way to 450F. Fan speed is what actually produces crisping, so a manufacturer quoting an rpm figure is telling you something most do not.
The other is the coating. The basket uses a PFAS-free ceramic non-stick rather than the PTFE coatings used almost everywhere else in this category. PFAS are the class of compounds behind most non-stick surfaces, and whether that matters to you is a personal call, but Cosori is one of very few brands making the claim explicitly rather than leaving you to guess. The 90F low end is genuinely useful for proving dough and dehydrating, which most fryers cannot reach.
What it does well
- 3,600 rpm fan with five speeds, published rather than implied.
- PFAS-free ceramic coating instead of PTFE.
- 90F to 450F range covers proving and dehydrating.
- Nine functions in a 6-quart basket.
What to know before buying
- Ceramic coatings historically wear faster than PTFE.
- Taller than the slim models, so check cupboard clearance.
2. Ninja Air Fryer Pro AF142: The Straightforward One
Ninja effectively created this category in its current form, and the AF142 is the version without complications. It is a 5-quart single basket with a 1,750-watt element and five functions: air fry, air roast, bake, reheat and dehydrate.
Max temperature is 400F rather than the 450F the Cosori and Chefman reach, which matters less than the spec sheet suggests for most cooking but does cost you some browning speed. The trade you are making is a smaller, simpler machine that takes up less counter than the dual-zone models and does the everyday job without a menu to learn.
What it does well
- 1,750W element in a compact 5-quart body.
- Five genuinely distinct functions rather than renamed presets.
- Smallest counter footprint of the basket models here.
- Ninja’s basket coating and build are well proven.
What to know before buying
- 400F ceiling is lower than the Cosori and Chefman.
- 5 quarts is tight for a family of four.
3. Ninja Foodi DualZone DZ302: Two Baskets That Finish Together
The single genuine innovation in air fryers since the original is the second basket, and this is the machine that popularised it. Ten quarts split across two independent zones, each with its own settings.
Two features do the work. Smart Finish runs both baskets on different settings and different times, calculating backwards so they finish at the same moment, which solves the real problem of protein and vegetables needing different treatment. Match Cook copies one basket’s settings to the other when you just want double capacity. If your complaint about air fryers is that they cook one thing at a time and everything else goes cold, this is the direct answer.
What it does well
- Two independent baskets with separate temperature and time.
- Smart Finish syncs two different foods to finish together.
- Match Cook doubles capacity for a single dish.
- 10 quarts total, the largest basket capacity here.
What to know before buying
- Physically large; measure your counter before ordering.
- Two baskets mean two things to wash.
- Each basket alone is smaller than a single 8-quart.
4. Chefman TurboFry 8 Qt: The Most Basket for the Money
Eight quarts in a single basket is the most usable volume here for cooking one large thing, a whole chicken or a full tray of wings, rather than two smaller things. Chefman pairs it with a 450F Hi-Fry setting, matching the Cosori at the top end.
The function list is short and honest: air fry, bake, reheat and a Frozen setting that defrosts before crisping, which is the one preset most people will actually use given what tends to go in these machines. Controls are a touchscreen. This is the value option of the group and does not pretend to be more.
What it does well
- 8-quart single basket, the largest undivided capacity here.
- 450F Hi-Fry for faster browning.
- Frozen function defrosts then crisps in one cycle.
- Usually the cheapest of the full-size models.
What to know before buying
- Four functions where others offer nine.
- Single basket means sequential cooking.
5. Cuisinart Air Fryer Toaster Oven: The One That Replaces Two Appliances
A basket fryer sits on the counter doing one job. This does eight, and the capacity is quoted in a way you can actually picture: Cuisinart states it toasts 6 slices of bread, air fries 3 lbs of chicken wings, bakes a 12-inch pizza or roasts a 4-lb chicken.
At 1,800 watts it is the most powerful appliance here, and the function list covers air fry, toast, convection bake, bake, convection broil, broil and warm. The trade against a basket is real: oven-style air frying is slightly less effective at crisping because the airflow is less concentrated, and the glass door and larger cavity take longer to come up to temperature. What you get back is a machine that removes your toaster and your countertop oven at the same time.
What it does well
- Replaces a toaster, a small oven and an air fryer.
- 1,800W, the most powerful unit here.
- Capacity stated in real terms: 12-inch pizza, 4-lb chicken.
- Easier to load flat food than a deep basket.
What to know before buying
- Oven-style crisping is a little less aggressive than a basket.
- Takes the most counter space of anything here.
- Longer preheat than a basket model.
6. bella Fits-Anywhere Slim: 6 Quarts in a Narrow Body
The usual objection to air fryers is that they are bulky objects that live permanently on a worktop. bella’s answer is a 6-quart basket in a deliberately slim body designed to fit gaps other fryers cannot.
It also uses what bella calls an EverGood non-toxic ceramic non-stick coating rather than a conventional PTFE surface, which puts it alongside the Cosori as one of the two here making that claim. Full capacity, less width. For a small kitchen that is the whole argument.
What it does well
- 6-quart capacity in a notably narrow footprint.
- Ceramic non-stick rather than conventional PTFE.
- Fits gaps that standard fryers will not.
- Sold in colours rather than black plastic.
What to know before buying
- Slim means deep, so check cupboard depth as well as width.
- Fewer functions than the Cosori or Ninja.
7. Ninja Crispi: The One That Cooks in the Container You Store In
This abandons the basket entirely. The Crispi is a palm-sized PowerPod that clamps onto borosilicate glass containers, supplied in 4-quart and 6-cup sizes with snap-lock storage lids.
The consequence is that you prepare, cook, serve and store in the same glass dish, then put the lid on and refrigerate it. There is no basket to wash and no permanent appliance on the counter, because the pod goes in a drawer. It reaches 450F, matching the full-size models. The limitation is obvious: capacity is smaller, and you are cooking in glass rather than a perforated basket, so airflow beneath the food is reduced and very crispy results are harder to achieve than in a mesh basket.
What it does well
- Cook, serve and store in the same borosilicate glass container.
- Pod stores in a drawer, freeing the counter permanently.
- 450F, matching the full-size machines.
- Two container sizes plus storage lids included.
What to know before buying
- Solid glass base restricts airflow under the food.
- Smallest capacity here by a distance.
- A different workflow that takes getting used to.
What Actually Determines Whether Food Crisps
Airflow, not temperature. The reason an air fryer beats a conventional oven at the same heat is fan speed and the perforated basket that lets air reach the underside of the food. This is also why overfilling the basket is the single most common mistake: food in two layers steams instead of crisping, no matter what the machine is set to.
A thin coating of oil still matters. The name promises otherwise, but crisping is a surface reaction that needs some fat. A teaspoon tossed through a basket of potatoes makes a visible difference over none at all.
Maximum temperature buys speed, not better results. The 450F machines here brown faster than the 400F Ninja. The finished food is similar; you wait less.
Capacity claims describe volume, not usable area. Because a single layer is the rule, a 10-quart dual-zone unit does not hold twice the food of a 5-quart basket. It holds two separate 5-quart-ish loads, which is a different and often more useful thing.
Basket, Dual-Zone, Oven or Pod
Single basket is right for one or two people who cook one component at a time. It crisps best because airflow is concentrated, and it takes the least space.
Dual basket solves the timing problem in a way nothing else does, and is the honest answer for a household cooking a protein and a side together. It needs the counter space.
Toaster oven style earns its footprint only if it replaces appliances you already own. As a pure air fryer it is slightly worse than a basket; as a toaster, oven and fryer in one it is comfortably ahead.
Pod and glass suits people who resent permanent counter clutter and cook small portions. It is the least effective at aggressive crisping and the most convenient to store.
Which Air Fryer to Buy
For most households the Cosori TurboBlaze is the pick. It publishes a fan speed rather than implying performance, reaches 450F, drops to 90F for proving and dehydrating, and uses a PFAS-free ceramic basket, which very few competitors offer at any price.
Buy the Ninja Foodi DualZone DZ302 instead if the thing that annoys you about air fryers is cooking one item at a time, because Smart Finish genuinely solves it. Buy the Chefman TurboFry if you want the most basket volume for the least money and do not need nine functions. Buy the Cuisinart if it can retire your toaster and countertop oven, which changes the space calculation entirely. Take the bella if your kitchen is short of width, and the Ninja Crispi if you would rather store the appliance in a drawer than look at it.
Whichever you choose, measure the gap it has to live in before ordering, including the clearance above and behind, because these machines vent hot air upwards and need room to do it. If you are rebuilding the kitchen counter generally, our drip coffee maker comparison covers the other appliance that occupies the same stretch of worktop, including the only two on Amazon with third-party brewing certification.
Frequently Asked Questions
What size air fryer do I need?
For one or two people, 4 to 6 quarts is enough. For three or four, either an 8-quart single basket or a dual-zone model. Remember that food needs to sit in a single layer for proper crisping, so quoted volume overstates how much you can cook at once.
Do air fryers really use less oil?
Yes, compared with deep frying, because you are circulating hot air rather than submerging food. You still want a small amount of oil for browning, so the realistic comparison is with oven roasting rather than with frying.
What is a PFAS-free air fryer?
Most non-stick baskets use PTFE coatings, part of the PFAS family of compounds. A PFAS-free basket uses a ceramic coating instead. The Cosori TurboBlaze and the bella Fits-Anywhere are the two here that state this explicitly.
Is a dual-basket air fryer worth it?
If you routinely cook two things that need different temperatures or times, yes. Smart Finish on the Ninja DualZone times both so they are ready together. If you mostly reheat or cook one item, a single basket crisps just as well in less space.
