Quick answer: For most UK households, a dual-zone basket air fryer in the 7–9L range hits the best balance of price and capacity. Below is how to actually choose one, not just a list of names.
Start With Household Size, Not the Model Name
Capacity matters more than brand for most people’s day-to-day happiness with an air fryer. As a rough guide:
- 1–2 people: 2–4L is usually enough for everyday meals and snacks
- 3–4 people: 5–7L, or a dual-zone model so you can cook two things at once
- 5+ people or regular batch cooking: 8L+, or an oven-style air fryer with multiple racks

Basket vs Oven-Style
Basket models are compact, preheat almost instantly, and are the easiest to clean — best for fries, snacks, and everyday cooking. Oven-style models (with a door and internal racks) trade some of that speed and convenience for genuinely large capacity and more versatility, particularly for baking or cooking multiple trays at once. Most UK households are better served by a basket model unless you’re regularly cooking for a crowd.
Single vs Dual Zone
Dual-zone models — most famously the Ninja Foodi range — let you run two baskets at different times and temperatures, syncing them to finish together. Genuinely useful if you regularly cook two different foods (say, chips and chicken) that need different settings. If you mostly cook one thing at a time, it’s an expensive feature you won’t use often.
What Actually Matters vs What’s Marketing
Worth paying for:
- A wide, genuinely useful temperature range (most go from around 40°C up to 200–230°C)
- Dishwasher-safe parts — makes daily cleaning far less of a chore
- A viewing window, if you like checking progress without opening the basket and losing heat
Less essential than it sounds:
- Wi-Fi and app control — nice if you multitask around the kitchen, unnecessary if you’re usually nearby anyway
- A very high maximum wattage — beyond a point it mostly affects preheat speed, not final results
- Preset food buttons — convenient, but the same result as looking up a time and temperature yourself
Budget Guide
- Under £60: Solid basic single-basket models. Fewer features, but perfectly capable of good everyday results.
- £60–£120: Where most dual-zone and larger single-basket models sit — the sweet spot for most households.
- £150+: Larger oven-style models, premium builds, and smart/app-connected features.
Frequently Asked Questions
Is a more expensive air fryer actually better?
Past a certain point, mostly no — you’re paying for capacity, extra features, or smart connectivity rather than meaningfully better cooking results. A well-reviewed £70 model will produce very similar food to a £200 one.
How much capacity do I actually need?
More than you think, generally. Air fryer capacity fills up faster than expected once food needs a single layer to crisp properly — sizing up slightly from your first instinct is usually the right call.
Do I need a dual-zone model?
Only if you regularly cook two different foods needing different times or temperatures in the same meal. If you mostly cook one dish at a time, a single larger basket serves you just as well for less money.
