Ninja has established itself as a dominant name in the air fryer market, particularly with its dual-drawer models designed for cooking multiple foods simultaneously. The range now includes several distinct variants: the large-capacity Ninja Foodi MAX Dual Zone AF400UK, the more compact AF300UK, and the innovative vertical Double Stack. Choosing between them depends on kitchen space, household size, and budget.
Each model employs Dual Zone technology, allowing two independent cooking compartments to work in sync or with separate settings. The core question for most buyers in 2025 is which version delivers the best balance of capacity, footprint, and running cost for their specific needs.

The AF300UK has a total capacity of 7.6L, while the AF400UK offers 9.5L — roughly 25% more food capacity, according to a comparison video. Woman & Home identifies the AF400UK as the biggest Ninja air fryer in the Dual Zone range, with two 4.75L drawers. The Double Stack also totals 9.5L, but its key advantage is a much narrower footprint: 28cm wide versus the AF400UK’s 41.5cm width, according to Ideal Home.
Is the Ninja Double Air Fryer 9.5 Litre Worth It? (Honest Review)
What makes the 9.5L model stand out?
The 9.5-litre total capacity of the AF400UK and Double Stack is well suited for households of 3–5 people. Both models can cook a full meal in one session, using separate drawers for different components. The AF400UK is often described as the best “classic” dual-zone choice for those who want maximum drawer space and do not mind a wider countertop footprint.
Is it easy to clean?
All three models feature non-stick, dishwasher-safe components. The AF400UK and AF300UK have removable baskets that go straight into the dishwasher. The Double Stack’s shelves are also dishwasher safe, which simplifies cleanup after layered cooking.
The smaller AF300UK is described as slightly more energy efficient to run. One comparison claims it can be up to 75% cheaper than an oven for some foods, versus about 65% savings for the larger AF400UK, because more space must be heated. Both represent significant reductions compared to a traditional oven.
Does it use less oil?
The manufacturer states that air frying can reduce fat by up to 75% compared to deep frying. Independent tests confirm a significant reduction in oil usage, though exact savings depend on the food type and cooking method.
How Does the Ninja Dual Zone Technology Work?
Sync and Match explained
Dual Zone technology allows each drawer to be set to a different time, temperature, and cooking function. The Sync feature ensures both drawers finish at the same moment, so a complete meal is ready together. Match copies the settings from one drawer to the other for larger batches of the same food.
What can you cook with it?
The core functions — Max Crisp, Air Fry, Roast, Bake, Reheat, and Dehydrate — are consistent across the AF400UK, AF300UK, and Double Stack, according to a comparison video. The Double Stack adds Stacked Meal racks that create four cooking spaces across two drawers, a feature not available on the other two models.

Price differences across models
One comparison video gives UK RRPs of about £149 for the AF300UK and £230 for the AF400UK. Another review notes the Dual Zone family commonly sits around £180–£200 depending on model and retailer. The Double Stack is typically priced at £200 or above. PriceRunner shows a spread of roughly £34 between the AF300 and AF400 models.
The cream colour variant of the Double Stack and Dual Zone models is increasingly popular as a kitchen aesthetic choice. Availability varies by retailer, with Currys and Amazon UK often stocking it, though not all colour options are consistently in supply.
Air fryer prices can shift significantly during seasonal sales. The AF400UK, launched in 2022, has seen periodic discounts as newer models enter the market. Tracking prices across multiple retailers before purchasing is advisable.

Why Has the Ninja Double Air Fryer Become So Popular?
The Ninja Double Air Fryer ecosystem has evolved significantly since 2020, moving from single-drawer units to sophisticated dual-zone and vertical stacking designs. The market is highly competitive, with Ninja dominating the mid-to-premium price segment. The addition of the Double Stack in 2024 addressed a clear consumer pain point: counter space. Price sensitivity remains high, and the integration of independent review data from outlets such as The Independent provides authenticity often missing from pure e-commerce listings.
