Air fryers have become a must-have kitchen gadget, and Ninja leads the way with its Dual Zone Air Fryer range. Both the Ninja MAX 6-in-1 Dual Zone Air Fryer DZ400UK (9.5L) and the Ninja 6-in-1 Dual Zone Air Fryer DZ300UK (7.6L) promise healthier, faster cooking with the flexibility to prepare two different dishes at once. But which model is the better fit for your kitchen?
Let’s compare them side-by-side.
Capacity & Size – How Much Can You Cook?
One of the main differences comes down to size:
-
Ninja DZ400UK (9.5L) – This is the larger option, perfect for bigger families or batch cooking. Each drawer can fit a 2kg chicken or up to 1.4kg of fries. Ideal for entertaining or cooking large portions in one go.
-
Ninja DZ300UK (7.6L) – Slightly smaller, each drawer holds a 1.6kg chicken or around 1kg of fries. Still generous enough for 6–8 people, but more suited to those with less counter space.
If you regularly cook for a crowd, the DZ400UK’s extra capacity will make a noticeable difference.
Cooking Functions – Same Versatility
Both models come with 6 cooking modes:
-
Air Fry – Enjoy crispy results with up to 75% less fat than traditional frying.
-
Max Crisp – Cook frozen favourites in minutes at up to 240°C.
-
Roast – Perfect for meats, fish, and vegetables.
-
Bake – For fresh bread, cakes, and desserts.
-
Dehydrate – Make dried fruits, veggie crisps, and herbs.
-
Reheat – Restore leftovers to their freshly-cooked taste.
Functionality is identical, so performance in terms of cooking style is the same. The main distinction is how much you can fit in at once.
Dual Zone Technology – Cook Two Foods, Two Ways
Both the DZ300UK and DZ400UK feature Ninja’s SYNC and MATCH settings:
-
SYNC lets you cook different dishes with separate times and temperatures, but have them finish together.
-
MATCH applies the same settings to both drawers – perfect for doubling up a recipe.
This means you can cook chicken in one drawer and roast potatoes in the other, or just make double portions when needed.
Energy Efficiency & Cooking Speed
While both are far more efficient than a traditional oven, there’s a slight difference:
-
DZ300UK – Can save up to 75% on your oven energy bill and cook up to 75% faster.
-
DZ400UK – Offers up to 65% energy savings and the same speed advantage.
If ultimate energy saving is your goal, the DZ300UK edges ahead slightly.
Design & Build
Both models have a sleek gunmetal grey finish with updated metallic trim. They include:
-
2x non-stick drawers
-
2x non-stick crisper plates
-
Dishwasher-safe parts for easy cleaning
-
Simple digital control panel with a countdown timer
The DZ400UK is slightly larger and heavier (8.8kg vs 8.2kg), so if storage space is limited, the DZ300UK may be the better choice.

Which One Should You Buy?
-
Choose the Ninja DZ400UK (9.5L) if you want maximum cooking space, often prepare large roasts, or regularly feed a big household.
-
Choose the Ninja DZ300UK (7.6L) if you prefer a more compact design, value slightly higher energy efficiency, or cook for smaller groups while still having the flexibility of Dual Zone cooking.
Either way, both models deliver the same crisp, delicious results Ninja is known for – it’s just a matter of size and efficiency.
Final tip: If you’re upgrading from a single-drawer air fryer, both of these models will feel like a massive leap forward in convenience and versatility.
