Best Air Fryers UK 2026: How to Choose & Cosori Picks

Choosing an air fryer comes down to four things: how much you cook at once, whether you want one big basket or two zones, how much worktop you can spare, and whether app control matters to you. Below are five Cosori air fryers that cover those needs, from the £109.99 Dual Blaze 6.4L to the £299.99 Turbo Tower Pro Smart, plus a short buying guide to help you decide. All five are our own models, so the differences between them are laid out plainly: a quick-pick table first, and a full comparison at the end.

Quick picks: which Cosori air fryer suits you?

Each pick below is the best fit for a different kitchen. They are compared with one another within our range, not ranked from first to last.

How we chose these air fryers

We looked at the things that decide whether an air fryer fits your kitchen: capacity, basket layout, how it heats, the functions and temperature range, how easy it is to clean, whether it has an app, the warranty and the price. The details come from each model’s official specifications and listed features. All five are our own models, so you won’t find other brands here, and each comes with a two-year warranty.^*

How to choose an air fryer

How much capacity do you need?

Capacity is measured in litres and tells you how much food fits in at once. How many people that feeds depends on what you cook, so use the table as a starting point.

Single basket, dual basket, stacked or convertible?

The layout changes how you cook more than the litre figure does.

• Single basket: the simplest set-up, one dish at a time. The TurboBlaze 6L and Dual Blaze 6.4L work this way.
• Dual basket, side by side: two independent baskets, so you can cook different foods at different settings. The Dual Basket 8.5L has two 4.25L baskets and a Sync Finish mode that makes both finish together.
• Stacked: two zones, one above the other, so you get dual-basket cooking without the width of a side-by-side model. The Turbo Tower Pro Smart is built this way.
• Convertible: one large basket that can be divided into two. The TwinFry 10L splits into two 5L zones.

If you are still weighing one basket against two, our dual vs single basket air fryer guide goes through the trade-offs in more detail.

How much worktop space do you have?

Check width and height before you buy. The TwinFry is the widest of the five at 51.8cm. The Turbo Tower Pro Smart is only 30cm wide but 40.5cm tall, so measure the gap under your wall units. The full dimensions are in the comparison table below.

What should you look for in performance and features?

• Heating: the Turbo Tower Pro Smart has dual heating elements in the lower basket. The TwinFry’s Dual Blaze system uses four heating elements, which we describe as no-flip cooking, and the Dual Blaze 6.4L heats from above and below with dual sensors.
• Fan: the Turbo Tower Pro Smart and TurboBlaze 6L both have a 5-speed fan matched to the cooking function.
• Temperature range: 30–230°C on the TurboBlaze, 35–230°C on the Dual Basket and 35–240°C on the TwinFry.
• Functions: from 7 on the Turbo Tower Pro Smart (including Dry and Proof) to 12 on the Dual Blaze 6.4L.

Do you need a smart air fryer?

The Turbo Tower Pro Smart and TwinFry work with the VeSync app, where you can control settings, browse recipes and monitor your cooking. Both have to be switched on by hand, and Alexa is not supported. The Dual Blaze 6.4L also uses the VeSync app for recipes and cooking history, and does not support Alexa either. The Dual Basket 8.5L and TurboBlaze 6L don’t have app control, so you set everything on the appliance.

What does an air fryer cost to run?

The formula is simple: watts ÷ 1,000 × hours = kilowatt-hours (kWh). Multiply that by the unit rate on your energy bill to get the cost. A 2,000W appliance running flat out for 30 minutes uses 1 kWh. Rated power is a maximum, so treat the result as an upper estimate: the heating element cycles on and off while it cooks.

The five Cosori air fryers

We have listed them from the highest price to the lowest. Each follows the same format, so you can compare like with like.

Cosori Turbo Tower Pro Smart: best for app control and stacked dual-zone cooking

The Pro Smart stacks two cooking zones one above the other, so you can cook two foods at once in a body that is 30cm wide. It is the Turbo Tower model with app control.

Why we picked it

• Dual heating elements in the lower basket, plus a 5-speed fan matched to each cooking function.
• Seven functions: air fry, dry, roast, bake, reheat, proof and grill.
• A DC motor designed to run quietly, and ceramic-coated food-contact surfaces.

Great for

• Cooking a main and a side at the same time without a wide, side-by-side appliance on the worktop.
• Proving dough or drying fruit and vegetables, as well as everyday air frying.
• Controlling settings and browsing recipes from your phone. You switch it on by hand, and Alexa is not supported.

Look elsewhere if

• Worktop space is the main limit. Short on room? Read whether the Turbo Tower Compact is worth it.
• You don’t need app control. The Turbo Tower Standard offers the same 10.8L capacity for £60 less, and our Turbo Tower comparison guide shows how the Compact, Standard and Pro Smart differ.

Cosori Dual Blaze TwinFry 10L: best for big batches and a flexible layout

The TwinFry gives you one large 10L basket for big dishes, or a divider that turns it into two 5L zones when you want to cook two things at once.

Why we picked it

• Dual Blaze heating with four heating elements, designed for no-flip cooking, and two baking racks included.
• Eight functions: air fry, roast, bake, reheat, dehydrate, grill, Sync Finish and Match Cook.
• It saves 66% energy compared with a traditional oven and cooks up to 65% faster.^†

Great for

• Roasting a whole chicken in the single large basket.
• Cooking two different dishes in the two 5L zones, with Sync Finish so both are ready together.
• Browsing around 70 online recipes in the app. As with the Pro Smart, you switch it on by hand and Alexa is not supported.

Look elsewhere if

• Worktop space is tight. At 51.8cm wide, it needs the most room of the five. The Turbo Tower Pro Smart is 30cm wide.

The Black model has a PFAS-free ceramic coating, while the Rose Gold model has a non-stick coating.

Cosori Dual Basket 8.5L: best for a dual basket at a lower price

Two independent 4.25L baskets let you cook a main and a side separately, and Sync Finish makes both ready at the same moment.

Why we picked it

• Sync Cook sets the same time and temperature for both baskets, while Sync Finish lets each basket run its own settings and finish together.
• Eight functions: air fry, roast, bake, reheat, grill, dry, Sync Cook and Sync Finish.
• It cooks up to 55% faster and saves up to 75% energy compared with a traditional oven.^†
• Non-stick baskets and accessories that are dishwasher-safe.

Great for

• Getting a main and a side ready together on a weeknight.
• Keeping two foods apart, for example when people at the table have different dietary needs.
• Trying a dual basket model without paying for extra features.

Tip: when you use Sync Finish, turn the preheat off on both baskets, otherwise the finish times will not line up.

Look elsewhere if

• You want app control. The Turbo Tower Pro Smart and TwinFry both work with the VeSync app.
• You often cook one big dish. Each basket holds 4.25L, so the TwinFry’s single 10L basket gives you more room.

Cosori Dual Blaze 6.4L: best for dual heating with no preheating

This single-basket model heats from above and below, and you tap the screen to start cooking without waiting for it to preheat.

Cosori TurboBlaze 6L: best for a family-size single basket

FAQ

What size air fryer do I need for a family of four?

It depends on what you cook. We list the 6L TurboBlaze for 3 to 6 people and describe the 6.4L Dual Blaze as suitable for family size. If you want to cook a main and a side separately, look at the 8.5L Dual Basket or a larger two-zone model.

Are dual basket air fryers worth it?

They are if you often cook a main and a side together, because each basket has its own settings and Sync Finish makes them ready at the same time. If you mostly cook one dish at a time, a single basket is simpler and costs less. The Dual Blaze 6.4L is £109.99, for example.

What is the difference between a dual basket and a stacked air fryer?

A side-by-side dual basket puts the two baskets next to each other, so it is wider. A stacked model like the Turbo Tower Pro Smart puts one zone above the other, so it is narrower but taller.

Do air fryers use less electricity than an oven?

Our air fryers use less energy than a traditional oven, and the figure differs by model: up to 75% for the Dual Basket 8.5L and 66% for the TwinFry 10L.^† To estimate your own cost, multiply the rated power in kilowatts by the hours of use and then by your unit rate.

Can you put foil or baking paper in an air fryer?

Only if your user manual allows it. Light paper can lift in the airflow and touch the heating element, so it must always be weighed down by food. Don’t cover the whole base of the basket either, because air needs to circulate. Never preheat with an empty liner inside.

Do I need a smart air fryer, and can I start it from my phone?

The Turbo Tower Pro Smart and TwinFry work with the VeSync app for settings, recipes and monitoring, but you have to switch them on by hand. The Dual Blaze 6.4L uses the app for recipes and cooking history. None of them supports Alexa, because of regulatory and safety requirements for portable cooking appliances.

Are Cosori air fryer baskets dishwasher-safe?

The Turbo Tower Pro Smart, TurboBlaze 6L, Dual Basket 8.5L and TwinFry 10L all have dishwasher-safe parts. The Dual Blaze 6.4L page describes a non-stick basket that is easy to clean, so check its user manual before using the dishwasher. For hand-washing tips, see our guide to cleaning an air fryer.

How long is the Cosori warranty?

All five models come with a two-year warranty.^*

Why does my air fryer cook food unevenly?

Common causes include overfilling the basket and food blocking the airflow. Our guide to why air fryers cook food unevenly explains the causes and how to fix them, and how an air fryer works covers the basics.

What can I cook in an air fryer besides chips?

All five models have more than air frying. Depending on the model, you can roast, bake, grill, reheat, dehydrate or prove dough. Our air fryer cooking times guide has settings to start from.

The bottom line

Pick by how you cook rather than by capacity alone. Choose a single basket for everyday family meals, a dual basket for a main and a side together, the TwinFry for big batches, and the Turbo Tower Pro Smart if you want a narrow two-zone model with app control.
