Compared with deep-fat fryers, air fryers are a more healthy way to cook as they use hot air and less cooking oil – or sometimes no oil at all.

　　Instead, air fryers blast hot air around a small cooking chamber. Their compact cooking space and fast circulation of hot air allows you to make crispy, golden-brown food more quickly than using an oven.

　　Looking for an air fryer from a popular brand? We❿ reviewed hero models from some of the biggest:

　　Generally, you can get an air fryer for as little as £40, but we❿ found that a decent model usually costs between £70 and £80.

　　There is a correlation between the price and quality of air fryers, but this does not mean that all expensive air fryers are good, nor the opposite.

　　In our tests, some cheaper air fryers were so poor that we named them Don❽Buys. We also found some pricier models that gave disappointing results, including soggy, limp or tasteless chips.

　　Unlike free-to-access websites, which typically get the air fryers they review as freebies or loans from manufacturers, we pay for all the appliances we test, so you can have complete trust in our verdict.

　　Our tests include an assessment of the cooking quality of frozen chips, chicken drumsticks and baguettes. For example, the best models turn out evenly cooked chips with a crispy golden brown exterior and fluffy insides. We mark down air fryers that produce greasy, soggy, undercooked or overcooked chips.

　　We also find out how speedy they are, how much energy they use, and how tricky they are to clean. The quickest air fryers take just 20 minutes to cook four portions of chips, and you don❽have to preheat. On the other hand, the slowest take over 45 minutes – that❼simply way too long to wait.✖Read more about .

　　This list of buying questions will help you narrow down your options and ensure you get the best air fryer for your needs:How much food do you typically cook? Most air fryers can cook around 800g (around four to six portions) of chips. Some can manage up to twice as much. If you have lots of people to cater for, opt for a larger capacity, or a model with double-level cooking or a second compartment.How much free worktop space or cupboard space do you have? Some air fryers are huge and heavy. The is 36cm high and 42cm wide, and weighs 10kg out of the box. Some also come with lots of extra accessories that you❵ need to find storage for. We always list power cable length in our reviews because it can determine how close you❵ need to place your air fryer to a socket.Do you prefer digital or manual controls? Digital models can make it easier to see how much cooking time is left. Some air fryer models come with smartphone control via an app.Do you own a dishwasher? If you have a dishwasher, choosing a model with dishwasher-safe parts will help save on cleaning time.How much are you willing to spend? Basic air fryers start from around £60, but models with extra features – such as multiple compartments – can set you back well over £200. The cheapest models will usually have a smaller capacity, too.

　　Manufacturers usually quote the total internal volume of their air fryers in litres as a guide to their size. However, this doesn❽always match our own measurements of how much food you can realistically fit inside an air fryer, as not all the internal space is usable.

　　This is why part of our lab test measures the optimal and maximum capacity of each air fryer in grams of food. The smallest air fryers we❿ tested can hold up to 400g of food – about two portions of chips and roughly equivalent to the amount of food you can fit on two baking trays in an oven. If you want to cook for more than four people – or you just have a particularly hungry household – air fryers such as the can fit almost twice as much (1.7kg).

　　Dual air fryers are also an option if you❻ cooking for more people. They can fit between 0.6kg and 2.3kg of food.

　　By reading our  air fryer reviews  you can see exactly how much food, such as chips or chicken, you can comfortably fit in an air fryer.

　　It is also possible for an air fryer with large external dimensions to have less space available inside for cooking than a smaller one.Our review Tech Specs include the width, height and depth of every air fryer we’ve tested.The ‘Small’ filter will help you to find all the best air fryers for two people that we’ve tested, based on their capacity. Our ‘Compare’ function makes it easy to compare your choice of small air fryers side by side.

　　This is the most common type of air fryer. They have a cooking bowl or basket with a handle, so you can shake your food during cooking. This helps ensure the food cooks evenly and makes it easy to lift out of the air fryer once it❼ready.

　　Sometimes they come with a stirring paddle, though we’ve found this doesn❽always make for better results.

　　ProsGenerally cheaper than oven-type air fryers.The handle on the bowl makes it simple to turn your food.Normally straightforward to use.

　　ConsYou can❽usually check on the progress of your food without stopping the air fryer and pulling the basket out.Cheaper basket models may lack additional functions such as pre-set programs.Often smaller in capacity than oven-type air fryers or multicookers.

　　Take a look at our  to see all of the models we❿ tested.

　　Right now, countertop cooking appliances are becoming bigger, bulkier and more feature-laden as they take on a multitude of cooking tasks.

　　While most air fryers can also roast, grill and bake, a multi cooker can also cook in other ways, such as pressure cooking, steaming and slow cooking.

　　All this versatility typically comes at a higher price, so it❼worth considering if you❵ use all the features before spending the extra cash.

　　In most cases, yes. If you❻ looking for a convenient appliance that will save you time and potentially money, an air fryer could be a worthwhile investment.

　　Our tests also prove that air fryers really can save you money, but only if you use them effectively by considering the cooking capacity and number of people you❵ be cooking for.

　　A word of caution though: if you❻ looking to recreate that chip shop taste at home, then you are likely to be disappointed. We find that foods made in an air fryer, and chips in particular, do have a fried quality but if you❻ used to deep-fried food, you❵ easily be able to taste the difference. If that fried food taste is your sole reason for buying, an air fryer may not be worth it.

　　Reliability is important too. See our guide to the most reliable .

　　Don❽pay over the odds for features that you❵ rarely use. Consider this list before you decide on a model.

　　All air fryers have timers that allow you to set how long you want your food to cook for, and show you how much cooking time is left. Some, such as the and , have manual dials that you turn to set the time, but most other air fryers, including the , have digital timers instead. A digital timer can make it easier to see at a glance how much time is left on the clock.

　　You’ll need to clean your air fryer every time you use it, so you might appreciate being able to put the various parts in the dishwasher and letting it do the work. Ideally, the basket/bowl, lid and stirring paddle should all be dishwasher safe, although this isn’t always the case.

　　Some models, like the , have a second cooking compartment that allows you to cook two different types of food (at different temperatures) at the same time. For example, you could make steak and chips without having to mix them together. See our guide to the .Grill – gives you the option of grilling your food instead of air frying it, handy for cooking things like meat and fish.Bake – permits you the option of baking, handy for making desserts or even pastries.Roast – allows for roasting potatoes and vegetables.Dehydrate – provides you the option of dehydrating fruit or veg.Reheat – enables reheating leftovers.

　　Some basket-type air fryers have baskets set at an angle. This tilt, combined with a rotating action, tumbles your food around, helping it cook more evenly.

　　A ❼art✩ir fryer is one you can control from your phone or tablet. You select the recipe you want to use from the app, which then sends instructions to the air fryer to cook the food to a particular temperature and length of time.

　　You can keep an eye on the cooking time using the app on your phone, and it will let you know once cooking is finished.

　　This is a fairly uncommon feature and products with smart capabilities that we❿ tested have come and gone from the market. But when we come across any more, we❵ be sure to flag them.

　　Some air fryers come with a paddle that automatically moves the food around as it cooks. However, we❿ found that some air fryers that stir your food for you don❽do a very good job, so while a stirring paddle does make it more likely that your food will be evenly cooked, it❼not guaranteed.

　　With most air fryers, you can set the temperature at which you want the food to cook. Typically, this ranges from 80°C to 200°C.
