Air fryers are one of the cheapest ways to cook food, so it’s no surprise that growing numbers are turning to them as a way to keep energy bills down during the current cost of living crisis. 

Air fryers can cost anywhere from around 8p to 22p to run for 20 minutes, which is long enough to cook most things that could take up to 30 minutes in a standard oven. The cost of using your oven for this length of time could be as much as 54p, according to Utilita, more than triple the cost of an air fryer.

Like buying any other kitchen appliance, which is the best air fryer for you is really down to personal preference and your needs. After all, the best option for a family of four probably won’t be the most suitable for someone living by themselves. 

If you’re tempted to buy an air fryer but are baffled by the array of different sizes, functions and price ranges, you aren’t alone. Here, we’ve rounded up the best air fryers in a number of different categories so you can find the one that’s right for you.

How to find the best air fryer

Air fryers are not only cheap to run but also offer a healthier way of cooking food as you are able to use minimal oil while still achieving a great crisp to your food.

If you’re looking to add an air fryer to your kitchen appliances, it’s worth considering the following points before you splash any cash, as they’ll influence the type of air fryer you might want:

What do you plan to cook in your air fryer?

Air frying may be a relatively new experience for even the most proficient cooks. As a starting point, it’s important to know that some things cook better than others in an air fryer.

Air fryers work by circulating hot air around your food, essentially mimicking the cooking process of deep frying, but without a lot of hot oil. This does mean, though, that they are better at cooking things you’d usually want to be crispy, such as chips, chicken wings, roasted veg or shepherd’s pie. They aren’t so great at cooking sauce-based dishes, so a curry or bolognese probably won’t work.

However, if you want your air fryer to do more than just air fry, some models come with additional features, such as grills, steamers, rotating paddles and even rotisseries. Of course, additional features make these machines more expensive, so you’ll need to weigh up whether it’s worth the markup.

How many mouths do you need to feed?

One of the biggest limitations of air fryers is their size, and despite behaving like a powerful fan oven, their capacity is considerably smaller. When using an air fryer, you’ll load up the basket with whatever it is you’re cooking, whether that’s chips or a piece of chicken, so it’s important to think about the cooking capacity.

If you’re cooking for one or two people you’ll probably need to buy an air fryer with a 2-4.5 litre capacity. However, if you’re cooking for two to four people then a larger one with a 4.5-10 litre capacity is probably better. If you’re regularly cooking for more people than this, then you might want something bigger.

To give an idea of space, a 2-4.5 litre air fryer will usually have enough space for two fillets of fish or chicken, or enough for two portions of chips. Air fryers that have a capacity of 4.5 litres or more are usually able to hold much larger items, such as pizza, a whole chicken or larger portions of vegetables or chips.

If you’re limited on space and opt for a smaller model, it’s worth bearing in mind that you’ll need to cook in multiple batches, which could mean that you end up paying more in energy than if you cooked it in a regular oven.

Have you got a price limit?

Air fryers vary hugely in price, ranging from £30 to £300 or more, so start your decision-making process with an idea of how much you’d like to spend. This way, you won’t go over budget.

How much counter space can you spare?

Few of us have a large amount of space to fill with appliances on kitchen surfaces, so choosing an air fryer that won’t take up your entire work space is important. They range in size from 9cm to nearly 50cm wide, and between 12cm and 80cm high and 9cm and 40cm deep, so measure the space where you plan to put it before choosing a model.

How much do you want to spend on running costs?

If you’re conscious of your energy bills, then it’s important to think about how much your airfryer will cost to run. Different models have different features so the running costs of air fryers can vary considerably. For example, smaller models (1000w) can cost around 0.4p a minute to run, whilst the largest models (2400w+) can cost double this. Although the difference is small, when you multiply this out by total cooking time and frequency of use, the cost can easily add up.

Compare the cost of usage to your oven

If you’re looking to buy an air fryer to cut your energy bills, then it’s important that you take the time to work out how much your oven is currently costing you.

According to Utilita, the following figures show how much you can expect to spend cooking with various types of cooker based on an average of 15 minutes of use each day:

ApplianceCost per day to runCost per week to runCost per month to runCost per year to run
Electric cooker28p£1.95£8.46£101.48
Dual cooker (part electric, part gas)24p£1.67£7.23£86.80
Gas cooker10p£0.71£3.06£36.67

Source: Utilita

The benefit of air fryers is that they can cook food faster than a standard oven, so while you might use your oven for 30 minutes, you might be able to cook the same thing in 24 minutes using an airfryer.

It’s important to look at how much energy an air fryer uses if you’re conscious about energy costs. The cheapest model we found had a power output of 900w, costing 8.2p for 20 minutes, whereas the most expensive had an output of 2460w, costing 22.53p for the same amount of time.

Generally, air fryers with lower wattage will cost you less to run.

Air fryers with the largest capacity

The largest air fryers on the market at the moment have a 22-litre capacity, but really anything over 10 litres should give you plenty of room to play with. The Daewoo halogen air fryer that we’ve linked to above also gets an honourable mention here, as it ranks as the  cheapest air fryer to run with the biggest capacity.

It’s worth noting that with the rise in popularity of air fryers, and particularly large air fryers, a number of these models are selling out quickly, and others have a one to two month lead time, so it’s worth keeping your eye on them if you’re after one.

Here are some of the best large capacity air fryers:

Cheapest air fryers

Air fryers with the largest capacity

The cheapest air fryers tend to be on the smaller side, but as they cost less than other models, they tend to sell out fast. If you’re trying to keep costs down, it’s worth checking places like Facebook Marketplace for second-hand air fryers rather than buying a brand-new one. 

If you’re set on buying new, however, we’ve rounded up some of the cheapest ones currently available.
