If you want a smaller appliance than a Ninja 5-in-1, first check the Ninja model number: “5-in-1” does not identify one specific kind of cooker. The clearest match in Ninja’s official results is the Foodi DZ090C, a 6-quart, two-basket air fryer—not a pressure cooker. For a smaller pressure cooker, consider the Instant Pot Duo Mini 3QT; for a compact air fryer, the Vortex Mini 4QT; and for both pressure cooking and air frying, the Duo Crisp 6QT. Each gives up something, so choose by the function you actually use and check your counter and storage space before buying.

Confirm which Ninja 5-in-1 you mean

The name alone is not enough for a fair comparison. Ninja makes different multi-cookers and combination ovens, and the strongest official match for “Ninja 5-in-1” is the Foodi DZ090C: Ninja describes it as a 6-quart, two-basket air fryer. The result does not establish that it pressure-cooks. Its detailed dimensions and current price were not verified, so there is no reliable basis here for saying a particular alternative is physically smaller or cheaper than that Ninja.

Before comparing, read the model number from the appliance label or product listing and note its actual functions. The DZ090C reference is based on Ninja’s official search result; its product page redirected to Ninja’s home page when opened.

Choose by the function you want to keep

For pressure cooking in less space: Duo Mini 3QT

The Duo Mini is the clearest fit if your priority is a compact pressure cooker rather than a replacement for every Ninja function. Instant Pot lists it at 3 quarts and 10.0 × 11.4 × 11.2 inches. Its smaller capacity is a real tradeoff, and it does not air-fry. The official US product collection listed it at $89.99 when accessed 2026-10-07. See the Duo Mini product page and verify the live price before purchase.

For air frying in a smaller-capacity appliance: Vortex Mini 4QT

If air frying is what you use most, the Vortex Mini keeps that role while reducing capacity to 4 quarts. Instant Pot lists six functions: air fry, bake, roast, broil, dehydrate and reheat. It is not a pressure cooker and does not offer dual baskets, so it is not a function-for-function substitute for the DZ090C. Instant Pot’s product page lists variant-dependent or missing prices, so check the exact variant and current local listing. See the Vortex Mini product page.

  • OUTDOOR GRILLING POWER: Engineered with the BTU cooking power of a full-size outdoor grill, the AG301 replicates the high-heat sear and char-grilled flavor of a gas or charcoal grill — right from your countertop, year-round.
  • COOK FROM FROZEN — CHAR-GRILLED IN UNDER 25 MINUTES: The AG301 takes frozen steaks, chicken breasts, burgers, and fish fillets straight from frozen to perfectly char-grilled in under 25 minutes — no thawing required.
  • AIR FRY WITH UP TO 75% LESS FAT: The 4-qt crisper basket air fries wings, fries, and more with up to 75% less fat than traditional deep frying* — crispy results with little to no oil. *vs. hand-cut deep-fried French fries.

For both pressure cooking and air frying: Duo Crisp 6QT

The Duo Crisp combines pressure cooking and air frying, using separate lids for those functions. Instant Pot lists an 11-in-1 design, 6-quart capacity and dimensions of 13.58 × 13.58 × 13.97 inches. Its capacity matches the likely Ninja reference, and the verified data do not show that it occupies less counter space. Instant Pot’s US air-fryer collection listed it at $269.99 when accessed 2026-10-07; that snapshot does not establish that it is cheaper than the Ninja. Check the Duo Crisp product page for current specifications and availability.

How to decide whether an alternative will fit

  • Measure the appliance and the storage space. Compare external width, depth and height—not just capacity or function count. Include room needed to open lids and use handles, and check whether a separate lid needs its own storage.
  • Match the functions you actually need. The Duo Mini trades air frying for compact pressure cooking; the Vortex Mini focuses on air-fryer functions; the Duo Crisp covers pressure cooking and air frying but does not have verified smaller dimensions than the likely Ninja.
  • Choose capacity for your household and meals. Moving from a 6-quart appliance to a 3- or 4-quart one means less cooking capacity. Smaller capacity may suit your kitchen, but it is not a like-for-like replacement.
  • Compare the live local price for the exact model. The cited prices are US listing snapshots, not guaranteed current prices or prices for other regions. Compare the same model and included accessories, and confirm the functions on its product page.
