Both are Ninja Foodi DualZone air fryers with two independent baskets that let you cook two foods two ways at once. The difference is size: the DZ201 holds 8 quarts total, the DZ401 holds 10, and the DZ401 adds a stainless steel finish. For two to four people, the DZ201 is usually enough. For larger households or bigger batches in each basket, the DZ401’s extra capacity is the reason to size up.
Quick verdict
- Choose the DZ201 if you cook for two to four people and want the more compact two-basket Ninja.
- Choose the DZ401 if you regularly cook larger portions in each basket, or want a stainless finish on a DualZone unit.

What’s actually different
Total capacity. The DZ201 splits 8 quarts across two independent baskets; the DZ401 splits 10 quarts across two baskets of its own. Both let you run Match Cook to copy one basket’s settings to the other for a full-capacity single-food batch.
Finish. The DZ401 has a stainless steel exterior. Ninja also states its non-stick cooking surface is 100% PFAS free.
Functions. Both run the same 6-in-1 set: Air Fry, Air Broil, Roast, Bake, Reheat and Dehydrate.
Footprint. The extra 2 quarts on the DZ401 come with a larger overall footprint — measure your counter space before sizing up.
Where Ninja’s DualZone range goes from here. Above the DZ401 sit the DZ302 and the DZ550 Smart XL, which adds an integrated Smart Cook thermometer — see the full Ninja lineup if you want to compare further up the range.
Who should buy which
Buy the DZ201 if you cook for two to four people and Smart Finish/Match Cook is the feature you want, without paying for extra capacity you won’t use regularly.
Buy the DZ401 if you routinely fill both baskets with larger portions, or specifically want a stainless finish. See our best air fryer for family of 4 guide if you’re sizing for a larger household generally.
