Ninja AF100UK Air Fryer Review – 3.8L, 1550W Rapid Circulation Review UK 2026 — Worth It?

The Ninja AF100UK has become one of the UK's best-selling air fryers because it makes excellent food quickly and cleans up fast. The 3.8L capacity sits in the sweet spot for households of two to four — large enough for a full bag of chips, chicken thighs or even a small whole chicken, without taking over the worktop.

The rapid hot air circulation technology really does deliver on crispiness. Chips come out genuinely crunchy on the outside with a soft interior, chicken skin crisps up properly, and frozen foods reheat as if they came straight from the oven rather than a microwave. The 1550W power heats up fast, and the 200°C maximum temperature handles most tasks with ease.

Ninja have kept the controls simple: a temperature dial, a time dial, and a mode selector for Air Fry, Roast, Reheat, and Dehydrate. There's no touchscreen to confuse and no app required. The crisper plate that sits in the basket lifts out for washing, and both pieces are dishwasher safe which makes cleaning the fastest part of using it.

If you're cooking regularly for five or more people you'd want the larger 5.2L XL model instead, and the lack of a viewing window is a mild frustration when cooking something new. But for everyday use by a small family, this is simply one of the best appliances you can put in a UK kitchen.
