Best Air Fryers (2026)

How to Choose an Air Fryer: A Complete Buying Guide

Air fryers have become one of the most popular kitchen appliances in British homes over the past few years, and it's easy to see why. They promise the crispy, satisfying results of deep-frying with a fraction of the oil, they heat up faster than a conventional oven, and they can handle everything from chips and chicken wings to roasted vegetables and even baked goods. But walk into any appliance retailer and you'll find shelves heaving with options at wildly different price points, with specifications that can feel bewildering if you don't know what to look for.

This guide cuts through the noise and gives you the practical knowledge you need to choose the right air fryer for your household — without wasting money on features you'll never use.

What to Look For

Capacity: Litres Actually Matter

Capacity is the single most important specification to understand before buying. Air fryers are rated in litres, but manufacturers tend to be optimistic about how much food those litres will realistically hold.

As a practical rule of thumb:

• 1–2 litres: Suitable only for a single person cooking snacks or small portions. Genuinely useful only if you live alone and cook modest amounts.
• 3–4 litres: The sweet spot for one or two people. Comfortably handles a couple of chicken breasts, a portion of chips, or a small roast. This is the most common size on the market.
• 5–6 litres: Good for a family of three or four. You can cook a whole chicken, a generous batch of chips, or multiple portions simultaneously.
• 7 litres and above: Family-sized or dual-basket models. If you're regularly cooking for four or more, or want to cook different foods at different temperatures simultaneously, you're in this territory.

The key mistake people make is underestimating how much space food actually needs. Air fryers work by circulating hot air around the food — if you pack the basket too tightly, the air can't circulate properly and you end up with uneven cooking and limp rather than crispy results. A 4-litre air fryer does not mean you can cook 4 litres of food; in practice, you should fill the basket no more than halfway to two-thirds for best results.

Wattage: Power and Preheating

Most air fryers sit in the 1,400–2,200W range. Higher wattage generally means faster preheating and more consistent temperatures, but it also means higher electricity costs per use.

For everyday cooking — chips, vegetables, reheating leftovers — anything above 1,500W is perfectly capable. Where higher wattage earns its keep is in larger models: a 7-litre air fryer genuinely benefits from 2,000W or more to maintain temperature when cooking larger quantities of food. For compact models under 4 litres, chasing wattage is largely unnecessary.

Worth noting: air fryers are still significantly more energy-efficient than a conventional oven for small-to-medium cooking tasks, even at higher wattage, because they reach temperature faster and cooking times are shorter.

Single Basket vs Dual Basket

Single-basket models are the classic form factor: one drawer, one cooking zone. They're simpler, cheaper, and easier to clean. For most households, they're entirely sufficient.

Dual-basket models have two independent cooking zones side by side, each with its own heating element and controls. The selling point is that you can cook chips in one basket and chicken in the other, finishing both at the same time. This is genuinely useful — but only in specific circumstances:

• You regularly cook full meals rather than single dishes
• You're cooking for three or more people consistently
• You frequently need to cook foods at different temperatures simultaneously

For one or two people eating relatively simple meals, a dual-basket air fryer is often overkill. The units are significantly wider — they'll take up more worktop space — and they're harder to clean because you have twice as many components.

Controls: Digital vs Analogue

Entry-level air fryers often use analogue dials for temperature and time. These are intuitive, durable, and require no learning curve. Their weakness is imprecision — you're setting approximate rather than exact temperatures.

Digital models offer precise temperature control (typically in 5°C or 10°C increments), preset cooking programmes, and in some cases app connectivity. The presets can be helpful for newcomers — a dedicated 'chips' programme at the correct temperature and time removes guesswork — but experienced cooks often ignore them and set temperature and time manually.

App connectivity and smart features are largely unnecessary for an appliance you're standing next to in your kitchen. Don't pay a premium for these unless they genuinely appeal to you.

Common Mistakes to Avoid

Buying Too Small

This is by far the most common regret reported by air fryer owners. A 2-litre model might look appealing because it's compact and inexpensive, but if you cook for two people and want chips with dinner, you'll find yourself cooking in multiple batches — which largely negates the time-saving benefit of the appliance.

Be honest about how many people you cook for regularly, and size up rather than down. An air fryer that's slightly larger than you need is more useful than one that's slightly too small.

Ignoring Cleaning Difficulty

Air fryer baskets and drawers need cleaning after every use, and some designs are significantly harder to clean than others. Before buying, check:

• Whether the basket and drawer are dishwasher safe (most modern models are, but not all)
• Whether there are intricate mesh panels or ridged surfaces that trap grease
• Whether the basket can be fully disassembled

A model that's slightly more expensive but trivially easy to clean is almost always worth the premium over one that's a pain to maintain. An air fryer you dread cleaning is an air fryer that ends up gathering dust.

Overvaluing Dual-Basket Features

Dual-basket air fryers are heavily marketed, and the 'SyncFinish' or 'MatchCook' type features that allow both baskets to finish simultaneously are presented as transformative. They can be genuinely useful — but for many buyers, the reality is that they end up using both baskets at the same temperature cooking the same food, in which case they've bought a very wide single-zone air fryer at a significant premium.

If your cooking genuinely involves preparing multiple components simultaneously at different temperatures, a dual-basket makes sense. If not, a larger single-basket model will serve you better and be easier to clean.

Price Tiers

Budget: Under £70

At this price point you're typically looking at single-basket models in the 3–4 litre range. Build quality is serviceable rather than premium, and controls are usually analogue or basic digital. These models handle the core job — chips, vegetables, chicken — perfectly well.

If you're new to air frying and want to try before committing to a more expensive model, or you're cooking for one or two people with straightforward needs, the sub-£70 market is a sensible place to start. Don't expect sophisticated presets, rapid preheating, or heirloom-quality construction.

Look out for: the quality of the non-stick coating (cheaper coatings degrade faster), and whether the basket is dishwasher safe.

Mid-Range: £70–£150

This is where the market becomes genuinely competitive and the options most interesting. At this price point you can expect:

• Better build quality and more durable non-stick coatings
• Digital controls with accurate temperature settings
• Larger capacity options (5–7 litres)
• Faster preheat times
• More comprehensive preset programmes
• Dual-basket options at the upper end of this range

For most British households — a couple or a small family of three — the mid-range is the optimal landing point. You get meaningfully better performance and usability compared to budget models without the premium price of flagship products.

Premium: £150 and Above

At this price point, you're typically looking at large-capacity dual-basket models or oven-style air fryers with multiple racks. These units can handle much larger quantities of food and often double as compact ovens — some include rotisserie functions, multiple rack positions, and dehydrating modes.

Oven-style air fryers are worth serious consideration if:

• You regularly cook for four or more people
• You want to replace or supplement your main oven
• You need to cook things that don't fit in a drawer-style basket (a whole joint of meat, for example)

Be aware that oven-style models take up significantly more worktop space and can be harder to store. They also tend to have more external surfaces to clean.

Specific Advice: Matching the Air Fryer to Your Household

Do You Actually Need Dual Baskets?

Ask yourself this honestly before reaching for a dual-basket model. Dual baskets work best for households that:

1. Cook full evening meals regularly (protein plus a side)
2. Have at least three people to feed
3. Often need different temperatures for different components

If you're cooking for two and your typical use is a batch of chips, some chicken thighs, or leftovers, a well-chosen single-basket model at 5–6 litres will serve you better. The internal basket of a dual unit is typically only 3.8–4.5 litres per side, and the divider creates cleaning complications.

How Many People Are You Cooking For?

• Solo: 3–4 litres is plenty. Don't be tempted by larger models; you'll just heat unnecessary air.
• Two people: 4–5 litres. This comfortably handles a complete meal for two.
• Family of three or four: 6–7 litres, or a dual-basket at 8–9 litres total. Size matters here — cooking chips in two batches for a family is a frustrating experience.
• Larger households or frequent entertaining: Oven-style models or the largest basket models. Expect to spend £150 or more.

What Will You Actually Cook?

Be realistic about your cooking habits rather than aspirational. Most air fryer owners use their machine primarily for:

• Chips and potato products
• Chicken pieces (thighs, wings, breasts)
• Reheating leftovers and takeaways
• Roasted vegetables

If this describes you, a mid-range 5-litre single-basket model is entirely sufficient. If you plan to bake, dehydrate, or use it as a full oven replacement, you'll want a more capable machine with oven-style functionality.

Final Thoughts

An air fryer is one of the more genuinely useful small appliances you can buy for a British kitchen — it excels at the everyday cooking tasks that a conventional oven handles inefficiently. But the best air fryer is the one that's properly sized for your household and realistic about your cooking habits, not the one with the most impressive specification sheet.

Start with capacity — that's the specification that will most directly affect your daily satisfaction with the machine. Then consider whether dual baskets genuinely suit your cooking style, and don't pay a premium for features like app connectivity or voice control that you'll use once and forget.

If you're buying your first air fryer and aren't sure where to start, a 5-litre digital single-basket model in the £70–£120 range will satisfy the majority of British households without overpaying for features or capacity you don't need.
