Air fryers are one of the most popular kitchen appliances of the last few years, and the range on offer can be confusing. Two models that look almost identical can differ a lot in how much food they cook, how evenly they cook it and how easy they are to clean. This guide walks through the points that make a real difference, so you can pick one that fits your kitchen and your cooking habits.

1. Capacity: match it to your household

Capacity is usually listed in litres or quarts. As a rough rule:

• 2–3 litres – one person, snacks and sides.
• 4–5 litres – two to three people, the most common size.
• 6 litres and up – families, whole chicken, batch cooking.

Remember that food needs space for hot air to circulate. A basket that is packed to the top will cook unevenly, so it is usually better to go one size up than one size down.

2. Basket, dual-basket or oven style

Single-basket models are compact and simple. Dual-basket models let you cook two foods at different temperatures and finish them at the same time – handy for a main and a side. Oven-style air fryers have shelves and a door, take more counter space, but can also toast, bake and dehydrate.

3. Power and heat-up time

Most models sit between 1,200 and 1,800 watts. Higher wattage generally means faster preheating and better browning on larger loads. If you plan to cook for several people, avoid very low-power units.

4. Cleaning

This is the point people regret ignoring. Look for a non-stick basket and crisper plate that are dishwasher-safe, and check that there are no hard-to-reach corners where grease can collect. Some people prefer ceramic coatings over traditional non-stick; both work well if you avoid metal utensils.

5. Controls and presets

Digital controls with a clear display are easier to use than dials, but presets are less important than they look – most cooking comes down to temperature and time. A shake reminder and an automatic shut-off are genuinely useful extras.

6. Noise and size

All air fryers make fan noise. If your kitchen is open-plan, check the product's listed noise level or user feedback. Measure the space under your cupboards too: some larger models are taller than you expect.

Whatever you choose, compare prices across a few retailers before buying – kitchen appliances are frequently discounted, especially around seasonal sales.
