How to choose the right air fryer

The single most consequential choice in buying an air fryer is capacity relative to how you actually cook, not how you imagine you might cook. A compact single-basket model suits one or two people preparing straightforward sides, but families quickly find themselves running multiple batches, which largely defeats the efficiency argument. Dual-zone models, such as the Ninja MAX 6-in-1 Dual Zone Air Fryer 9.5L, address this by letting you cook two different foods at different temperatures simultaneously — a genuinely practical feature rather than a marketing embellishment. The newer stacked drawer format, like the Ninja Double Stack XL 9.5L Air Fryer, achieves comparable capacity in a notably smaller footprint, which matters a great deal in typical UK kitchens where worktop space is at a premium. Think carefully about the physical dimensions of any model before you buy, because capacity in litres tells you nothing about how much counter it will occupy.

Beyond size, the proliferation of function counts — four-in-one, seven-in-one — deserves scepticism. Additional modes are genuinely useful only if they replace appliances you already own or would otherwise buy. The glass-bowl designs, such as the Ninja CRISPi 4-in-1 Portable Glass Air Fryer or the larger Ninja CRISPi PRO 7-in-1 XL Glass Air Fryer, offer the practical advantage of being able to see what is cooking without opening the drawer and losing heat, and the glass vessel is somewhat easier to clean than textured non-stick baskets — but neither of those traits justifies paying a significant premium if the function count is otherwise surplus to your needs. Where tracked price history earns its keep is precisely here: knowing what a model has historically sold for tells you whether a retailer's current "seven functions for the price of five" promotion actually reflects a price reduction, or whether the launch price was always artificially high to make the current figure look attractive.

Who should look elsewhere

If you cook in very large volumes — roasting a full joint, baking bread, or regularly feeding more than four or five people in a single sitting — a countertop air fryer is likely to frustrate you regardless of which model you choose, and a compact oven with a convection or fan-assisted setting may serve you better without the capacity compromise. Equally, if your budget sits firmly at the lower end of the market, it is worth being honest that the tracked range shown on this page skews towards established mid-to-premium brands; there are cheaper air fryers from less prominent manufacturers that may suit a tighter budget, and our tracked set does not cover the full breadth of what is available in the UK market. Anyone with very limited worktop space and no permanent storage option should also consider whether any air fryer — including the more upright, space-conscious designs like the Ninja Air Fryer PRO 4.7L — is genuinely workable in their kitchen before committing.
