Ninja is a small-appliance brand that has bet on different formats. Among Ninja air fryers there are dual-zone models, for cooking two foods at once, and the Crispi range, with glass containers that can also be used for storage.

• Anyone who wants to cook two foods at once in a single appliance thanks to the dual zone.
• Anyone who prefers glass containers over non-stick metal baskets.
• Anyone who values a different design and compares features beyond litres.

• Usable capacity. Choose based on how many people you cook for; the advertised litres don't always equal the real amount of food.
• Power and consumption. The wattage is on the label. If you want to work out the cost, see how much power an air fryer uses.
• Cleaning. Check the model's manual to see which parts can be washed and which can't.
• Warranty and spare parts. Verify the statutory warranty and the availability of replacement parts.
• Compatible accessories. Liners, racks or moulds must fit the size of your basket; take a look at the air fryer accessories.
