Full Ninja Foodi MAX Dual Zone AF400UK review: specs, who it suits, FAQs
Our verdict
A good fit if you…
- cook for a family of three or four and want the main and the sides ready at the same time
- want the air fryer most UK owners already use, backed by one of the largest pools of Amazon UK ratings
- want dishwasher-safe baskets and crisper plates
- want to use the oven less and cook most weeknight meals in one appliance
Look elsewhere if you…
- –have limited worktop space – the side-by-side design is wide (the Double Stack XL is narrower)
- –want to cook a whole chicken or a large joint in one go – each basket is 4.75L and they can't be combined
- –like watching food cook – there's no viewing window

The key specs, in plain English
- 9.5L total (2 × 4.75L baskets)
- Two separate drawers, each with its own temperature and timer. One drawer will do chips for two; both together will feed four. The two baskets can't be combined into one big space.
- Sync and Match functions
- Sync works out the start times so that, for example, chicken and chips cooking at different temperatures finish together. Match copies one drawer's settings to the other when you're cooking a double batch.
- 2470W power
- High wattage means it heats up and recovers quickly. It still usually costs much less to run than heating a full-size oven for the same food, because it heats a much smaller space for less time.
- 41 × 32 × 27cm, 8.2kg
- Measure the gap under your wall cupboards and leave space around the rear vent. It's a machine you'll want to leave out on the worktop rather than put away after use.
Choose the Ninja Foodi MAX Dual Zone AF400UK if…
you have the worktop width, want wider baskets that are easier to load and clean, and want the lower price.
Choose the Ninja Double Stack XL SL400UK if…
your worktop is tight. It gives you the same 9.5L dual-zone capacity stacked vertically in a smaller footprint, for a bit more money.
Ninja Foodi MAX Dual Zone AF400UK: common questions
Can the Ninja AF400UK cook a whole chicken?
Only a small one, as each basket is 4.75L. If you regularly roast whole chickens, the Ninja FlexDrawer AF500UK has a 10.4L MegaZone that's designed for it.
Are the baskets dishwasher safe?
Yes, the baskets and crisper plates are dishwasher safe. Hand-washing can help the non-stick coating last longer.
Is it noisy?
It's about as loud as most air fryers, but owners mention it's louder on the Max Crisp setting. It's a fan noise, so it's more noticeable in an open-plan kitchen.
Is the AF400UK usually cheaper on Black Friday?
It's one of the most heavily promoted air fryers in UK sales. Check its price history before buying – our air fryer Black Friday guide explains how to tell a real saving from an inflated "was" price.
