What size air fryer do I need?

As a rough guide, 3-4L suits one or two people, 5-6L suits a small family, and 7L and up (often dual-zone) suits larger households or batch cooking. Check the usable basket size, not just the headline figure.

Is a dual-zone air fryer worth it?

If you cook different foods that need different times or temperatures, dual zones are genuinely useful, letting you finish two things at once. For simple single meals, a single basket is cheaper and just as good.

Are air fryers cheap to run?

For smaller portions they're usually cheaper than heating a full oven, since they're smaller and faster to get up to temperature. Running cost depends on the wattage and how long you cook.

Air Fryer Buying Guide: How to Pick the Right One…

Air fryers went from novelty to kitchen staple fast, and for good reason: they cook quickly, use less oil and cost less to run than a full oven for everyday portions. But there are a lot of them out there, and the differences matter more than the marketing suggests. Here’s how to pick one you’ll actually keep using.

The short version

Match the capacity to your household, decide if you need dual zones, and check the wattage for running cost. Dishwasher-safe parts save you real hassle. Bigger isn't better if it won't fit your worktop.

Capacity: the decision that matters most

Get this right and you’ll love it; get it wrong and it gathers dust. Too small and you’re cooking in batches, too big and you’re wasting energy heating empty space. As a rough guide, 3 to 4 litres suits one or two people, 5 to 6 litres suits a small family, and 7 litres or more suits bigger households. Look at the usable basket size in reviews, since the headline capacity can be optimistic.

Single or dual zone?

Dual-zone models have two separate baskets, so you can cook your chips in one and your chicken in the other, finishing them together even if they need different settings. If you regularly cook full meals, that’s a real time-saver. If you mostly reheat or cook one thing at a time, a single basket is cheaper and does the job just as well.

Watts and running cost

A higher wattage heats faster but draws more power while it runs. Since air fryers are small and quick, they still tend to beat a full oven on cost for everyday portions. If running cost matters to you, compare the wattage and think about how long your typical meals take.

Features you’ll actually use

Ignore the long feature lists and focus on what you’ll use day to day: a clear display, a few useful presets, and a decent temperature range. The one that quietly matters most is cleaning, so look for dishwasher-safe baskets and a non-stick coating. Reviews will tell you fast whether a model is a pain to clean.

Where it goes matters too

Air fryers are chunky and they need room to vent, so measure your worktop and check the height under any wall cabinets before you buy. A great air fryer that has nowhere to live is no bargain.
