TL;DR
- Worth it for most people who eat chips, wings, roast veg or reheat leftovers a few times a week.
- Speed and crunch are the real wins, not health miracles.
- Skip it if your counter is tiny, you cook for a big family in one go, or you rarely fry or roast.
- Cheap to run and no preheating a whole oven, so weeknight cooking gets easier.
- Downsides: small capacity, another gadget to store and clean, and mixed results with wet or battered food.

An air fryer is a small convection oven with a strong fan. That fan is the whole trick: it dries the surface of food fast enough to brown it, so you get crunch with a fraction of the oil. Whether that is worth your money and counter space depends on how you actually cook.
We buy and test every model on this site, so here is the honest version, not the marketing one. Our full method is in how we test air fryers.
What an air fryer does well
Crisping is where it earns its place. Chips, wings and roast vegetables come out golden without a pan of oil, and it reheats pizza or leftovers better than a microwave ever will.
Speed helps on a weeknight. A basket reaches temperature in two to three minutes, so you skip the long oven preheat. It also keeps the kitchen cooler in summer and costs little to run, as we break down in air fryer running costs.
Where an air fryer falls short
Capacity is the big one. Most baskets cook a single layer, so a family meal means cooking in shifts. Our size guide helps you avoid buying one that is too small.
Wet or heavily battered food struggles, because the fan blows loose coating around before it sets. And it is one more thing to store and wash, though cleaning is quick if you keep on top of it with our cleaning guide.
| Air fryer wins | Air fryer struggles | |
|---|---|---|
| Crisping | Chips, wings, roast veg, frozen food | Wet batter, saucy dishes |
| Speed | Fast preheat, quick weeknight meals | Large batches (cooks in shifts) |
| Cost | Cheap to run vs a full oven | Upfront cost of another gadget |
| Space | Compact models exist | Takes counter or cupboard room |
Is an air fryer healthier?
A little. Air frying uses far less oil than deep frying, so it cuts fat and calories on foods you would otherwise deep fry. Cooking meat at high heat can still create the same browning compounds any high-heat method does, so it is not a health halo, just a lighter way to get crisp results.
Who should buy one, and who should not
Buy one if you cook for one to four people, like crispy food, and want faster weeknights. Start with our best air fryers roundup and recipe collection.
Skip it if your kitchen is short on space, you already own a good air fryer oven or toaster oven, or you mostly batch-cook big trays for a crowd.
Frequently asked questions
Are air fryers actually worth it?
For most households, yes. If you regularly cook chips, wings, roast vegetables or reheat leftovers, an air fryer is faster than an oven, crisps better than a microwave and costs little to run. If you rarely fry or roast, or you cook large batches for a big family, the small capacity may frustrate you.
What are the disadvantages of an air fryer?
The main ones are small capacity, so family meals cook in shifts; poor results with wet batter or saucy food; and the fact that it is another appliance to store and clean. Larger dual-basket and oven models solve the capacity issue but take more space.
Does an air fryer use a lot of electricity?
No. Because it heats a small chamber for a short time and skips a long oven preheat, a typical air fryer costs only a few pence or cents per use. See our running costs guide for the kWh maths.
Is air-fried food healthy?
It is lighter than deep-fried food because it uses little or no oil, which cuts fat and calories. It is not a health cure, though; cooking meat at high heat still produces the usual browning compounds, so balance is key.
Can an air fryer replace my oven?
For small and medium portions, often yes. It struggles to replace an oven for big roasts, large trays or batch baking. Many people use both: the air fryer for weeknight crisping and the oven for big cooks.
