When someone asks us about an air fryer, at the counter or in writing, we don't start with "how much do you want to spend?". We start with another question: "how many of you eat at home?". And we're not asking to be difficult. The most expensive mistake with an air fryer isn't buying a bad one; it's buying the wrong size. One that is too small forces you to cook in two batches every evening and ends up in the cupboard. One that is too big takes up half the worktop, takes longer to heat up and uses more power than the food inside needs.

So this guide is not yet another list of "the best air fryers of 2026". That universal list doesn't exist: the best one for a couple is not the best one for a family of six. Here you will see which one suits you, whether there are two, four or seven of you at home, with real numbers and no frills. We are a family shop in Albox with many years behind the counter, and we would rather you get it right the first time than have to handle a return.

First, understand how it works (and why capacity rules)

Inside, an air fryer is a small convection oven: a fan moves very hot air at high speed around the food, and that air is what browns it and makes the surface crisp without anything being dunked in oil. There is no other trick. And because the circulating air does the work, the space in the basket matters a great deal. If you pile the food up, the air can't get between the pieces and, instead of crisp, it comes out soft, almost steamed.

That is why the variable that really decides the purchase is capacity. These are the ranges that work in a real kitchen, which don't always match what the box promises:

1-2 people: around 4 litres.
3-4 people: between 5 and 6 litres. This is the best-selling range, and for good reason.
5 or more: 8-10 litres, a dual-basket model (dual zone) or simply a countertop oven with an air fry function.

Make a note of those numbers, because now comes the nuance that almost no product listing explains.

Litres on the box versus usable litres: count on half

The nominal capacity printed on the carton (5.5 L, 6.5 L, 8 L) is not the capacity you can use while keeping the food crisp. It is the total physical volume of the basket, right up to the brim. If you fill it to the top, the air stops circulating and the result drops sharply.

The rule we give everyone who comes in is simple: count on roughly half of the advertised litres for a portion that comes out properly golden. A 5.5 L air fryer works well for three or four portions spread in a single layer; a 6.5 L gives you that extra margin for when there are four of you with big appetites or you load the tray a bit fuller.

In day-to-day practice:

Chips for four without piling them up: you need about 5-6 L nominal.
A small whole chicken: from 6 L, and it's a tight fit.
Two portions (a couple, or someone cooking for two days): 4 L is more than enough.

With this in mind, nobody will sell you a mini 3-litre model saying it's "for the whole family".

If there are 1 or 2 of you: compact, and that's it

If you live alone, as a couple, or cook small portions, an air fryer of about 4 litres is the right fit. With the half rule you have about 2 usable litres: plenty for two portions of chips, a couple of chicken fillets, vegetables, or reheating yesterday's pizza so it comes out crisp instead of rubbery.

What you can do without in this case:

The dual basket. For two people it means paying for worktop space you won't use.
High 2000 W power. You don't need it for small portions.
The panel with twenty programmes. In practice you will end up using three: chips, chicken and manual mode. It's nice to have them, but that is not where the budget should go.

What does matter here: that it is compact, easy to store and has a non-stick basket you can clean in two minutes. For a home of one or two people, simple and well made does more than big and full of features.

If there are 3 or 4 of you: the 5 to 6 litre range

This is the middle of the market and, most likely, your case if you are reading this. A family of four, or of three with teenagers at home, works very well in the range of 5 to 6 litres. It is also the purchase that generates the fewest returns for us, because it suits almost everyone.

Within this range we work with two Orbegozo models that cover both ends:

The Orbegozo FDR 67 Freidora de Aire 5,5 L 1700 W 8 Programas Sin Aceite is the workhorse for 3-4 people. 5.5 litres, 1700 W, eight programmes and simple controls. For the everyday needs of an ordinary family it does the job without problems.
The Orbegozo FDR 6510 Freidora de Aire 6,5 L 1700W 8 Programas Táctil is the same idea with one more litre and a touch panel. It is the one we recommend if there are four of you with good appetites or you are at the top end of the range: that extra litre is exactly what saves you from cooking in two batches.

Notice one detail: both have 1700 W. Why that figure suits these litres we cover next, in the power section. And a seasonal note: in summer, being able to sort out dinner with 1700 W for twenty minutes without switching on the big oven stops the kitchen from turning into an oven for you too. In July and August it is, by a long way, what we sell most in this category.

If there are 5 or more of you: dual basket or an oven with air fry

If you are a large family, get together often or cook for several days at once, a single basket will leave you frustrated, cooking in batches. Here you have two routes, and they follow different philosophies.

Route 1: dual basket (dual zone). This is the strong trend of 2026, and it's not just marketing. It has two independent compartments that cook at different temperatures and times and finish together. You can do the chips in one zone and the fish in the other, each one done to perfection, and take everything out hot at the same time. For anyone who puts together full meals it is a real change. The downside: they take up quite a lot of worktop and the good ones are not cheap.

Route 2: countertop oven with air fry function. If, besides the air fryer effect, you want to grill, bake a tray of biscuits or roast properly, a countertop oven with built-in air fry gives you both. This is where the Horno Infiniton B698-AF 60L Inox comes in: 60 litres, stainless steel finish and a built-in air fry function. A really large tray fits, so for five or more people, or for anyone who prefers a single appliance that does almost everything, it is the most versatile option. It is not a basket air fryer: it is a full oven that also air fries. That difference is exactly what many large families are looking for.

Watts per litre: the figure almost nobody checks

Here is the piece of data that almost no review mentions. Don't look only at the power. Don't look only at the litres. Look at the ratio between the two: divide the watts by the litres and you will know whether the appliance has the muscle for its size.

As a reference, the comfortable range starts at around 300 watts per litre and goes up; between 400 and 450 W/L you have a very generous appliance that preheats quickly even with a full basket. Note that it is not a pass or fail: below 300 W/L in large models is where browning problems begin. With the numbers in hand it is clear:

A 5.5 L air fryer with 1700 W gives about 309 W/L: more than enough for normal home use and very well balanced.
A 6.5 L one with 1700 W drops to about 262 W/L: still valid, although you will notice it preheats a little more slowly with a well-loaded basket. Nothing dramatic for ordinary use, and in return you gain capacity.
A mini 4 L with 1400 W comes to around 350 W/L: nimble and quick for small portions.

Typical household power runs from 1400 to 1700 W, with large models reaching about 2000 W and minis starting at around 800 W. The practical conclusion is this: beware of the huge air fryer with mini-sized power. If you see 8 litres with 1200 W, that appliance won't have the strength to brown all that volume properly and will end up cooking in batches anyway. A big litre figure, on its own, means nothing.

How much it really uses compared with the big oven

It is one of the questions we get most, with electricity prices as they are. And the answer is good: the air fryer uses noticeably less per meal than a traditional oven for small and medium portions, and the reason is pure common sense.

The big oven has a large volume of air to heat and needs a long preheat before you put anything in. The air fryer is a small chamber that reaches temperature in a couple of minutes and cooks faster. A 1700 W air fryer working for 20 minutes, with almost no preheating, uses far less than preheating and running the big oven for that same dish of chips or those wings.

In broad strokes, to give you an idea:

Air fryer: 1700 W, about 20 minutes, practically no preheating. Small consumption per meal.
Big oven: more power, much more volume to heat and a long preheat. The cost multiplies for the same result with small and medium portions.

Add that in summer you don't heat up the kitchen, so you also save a little on air conditioning. That said, let's be honest: if you are going to roast a whole lamb or cook for twelve, the big oven is still the right tool. The air fryer shines in the everyday cooking of small and medium portions, which is most of what we cook at home.

Myths and mistakes that ruin the result

At the counter we hear the same misunderstandings again and again. They are worth clearing up, because the difference between loving the appliance and leaving it to gather dust is right here.

Myth: "it fries with no oil at all". That's not accurate. It fries with very little oil, not none. A teaspoon or a spray over the chips or the chicken makes the difference between crisp and dried out. The air does most of the work, but a little fat helps with browning. "Oil-free" is a figure of speech, not a literal instruction.
Myth: "the bigger, the better". We have already seen it: a huge air fryer for two people is a worse experience, not a better one. It heats more slowly with a half-empty basket and takes up worktop space for nothing. Size is chosen by the number of people eating, not out of fear of coming up short.
Mistake: overfilling the basket. The most common failure of all. If you pile the food up in a mountain, the air doesn't circulate, the bottom steams and nothing comes out crisp. A single layer, with gaps between the pieces. If it doesn't fit, do two batches: it takes longer, but it comes out right.
Mistake: not turning or shaking the food. Halfway through cooking, shake the basket or turn the pieces. It takes ten seconds and changes the result completely.

What comes out brilliantly and what is better left in the frying pan

You won't read this on a technical data sheet, but it is what you really want to know before paying. After years of selling them and using them at home ourselves, this is what comes out perfectly in an air fryer:

Chips and potato wedges, frozen or homemade. The star dish.
Wings, drumsticks and chicken in general: crisp outside, juicy inside.
Frozen croquettes and empanadillas: like freshly made.
Roasted vegetables, crispy chickpeas, toasts.
Reheating any fried food from the day before. Here it has no rival: it revives it like the first day.

And this is what is better left in the frying pan or the oven, with no false promises:

Foods coated in liquid egg batter, omelettes or fried eggs: they drip and make a mess.
Very runny batters or tall sponge cakes, unless the air fryer is one of those that bakes well.
Large quantities in one go: that is what the big oven or the 60 L Infiniton are for.

On everyday cleaning, which you also ask about a lot: the basket and the rack are usually non-stick and either go in the dishwasher or are cleaned with a soft scourer in a minute. The honest trick is to clean it while it's still warm, as soon as you finish. If you let the grease dry and stick, it then takes three times as long. Done straight away, it is one of the most grateful appliances in the kitchen.

Our direct recommendation for your case

To sum up everything above, so you don't have to go back:

There are 3-4 of you (the most common case): the Orbegozo FDR 67 5.5 L. The safe option for everyday family life.
There are 4 of you with good appetites or you are at the limit: the Orbegozo FDR 6510 6.5 L, touch panel and with that extra margin you will appreciate.
There are 5 or more of you, or you want an appliance that does almost everything: the Horno Infiniton B698-AF 60 L with air fry function. It air fries and also bakes, grills and roasts a large tray.

You can see these and the other options in our small appliances collection. As a price guide, without tying ourselves to a specific model: the basic ones usually start from around €50-60, and the dual-basket ones or full ovens can go over €150. What makes the difference is size and versatility, not the brand on its own.

Frequently asked questions about air fryers

What size of air fryer do I need for the number of people at home?

For 1-2 people, about 4 litres. For 3-4 people, between 5 and 6 litres (the best-selling range). For 5 or more, 8-10 litres, a dual-basket model or a countertop oven with air fry. Remember to count on half of the nominal litres as the capacity that is really crisp.

Why do they say you should count on half of the litres?

Because the nominal capacity on the box is the total volume of the basket up to the brim, but if you fill it completely the air doesn't circulate and the food doesn't come out crisp. For a nicely golden result you need to cook in a single layer, so the real usable capacity is around half of the advertised one.

How much power should an air fryer have?

Typical household power runs from 1400 to 1700 W, up to about 2000 W in large models. As a reference, divide the watts by the litres: from about 300 W per litre it performs well, and between 400 and 450 W per litre you have a very generous appliance. Be wary of very large air fryers with low power, because they won't brown the whole volume properly.

Does an air fryer use less than the oven?

Yes, quite a bit less per meal for small and medium portions. Being a small chamber it heats up in a couple of minutes and cooks quickly, while the big oven needs a long preheat and has much more volume to heat. For large roasts or cooking for many people, the traditional oven still makes sense.

Is it true that it fries with no oil at all?

Not entirely. It fries with very little oil, not none. A teaspoon or a spray helps the food brown and come out crisp instead of dried out. The hot air does most of the work, but a minimum of fat greatly improves the result.

What guarantee and returns do I have when buying at Híper Ocio?

You get a 3-year guarantee, the legal one in Spain, and 30 days to return the product if you are not convinced, under our returns policy. In addition, delivery is free anywhere in Spain from €49.99 because it is a small appliance.

Updated in September 2026: if you are also wondering whether the air fryer is healthy, with the acrylamide question and how much electricity it uses, we have explained it with data from OCU and AESAN in Is the air fryer healthy? Acrylamide and electricity, no scares.
