Which Ninja Double Oven models does this basket fit?

Ninja lists it as compatible with a wide range of Double Oven models. Check your oven's model number against Ninja's compatibility list before buying, since it is made for the Double Oven line rather than standard ovens.

Can I use it for dehydrating as well as air frying?

Yes. The mesh is designed for airflow, which suits dehydrating fruit, vegetables and jerky as well as air frying wings, fries and vegetables.

Does the mesh let small pieces fall through?

The mesh is open to let air through, so very small or thin pieces can slip through the gaps. Use it for larger pieces or line it when working with fine food.

Is it dishwasher safe?

Ninja does not state dishwasher use for this basket. Hand washing in warm soapy water is the safe way to keep the chrome finish clean.

Is it worth buying as a spare?

If you air fry often in your Double Oven, a second basket lets you cook one batch while another is in use or being cleaned. If you rarely use the air fry mode, the basket that came with your oven is enough.
