The useful question is not which air fryer looks newer. It is whether your household needs a flexible glass-container routine or a larger basket for recurring meals. Here we compare the Ninja Crispi 4-in-1 FN101ST with the Ninja Air Fryer Pro XL AF181, a 6.5-quart single-basket model.

The quick answer
Consider Crispi if smaller portions and cooking or storing in compatible glass containers match your routine. Consider the AF181 if a larger single basket and additional cooking modes matter more than container flexibility. Neither model offers two independently controlled cooking zones.
| Feature | Crispi FN101ST | Pro XL AF181 |
|---|---|---|
| Cooking vessel | Glass-container system with removable heating pod | Single nonstick basket |
| Included capacities | 4-quart and 6-cup containers | 6.5-quart basket |
| Modes | Max Crisp, Bake, Air Fry, Recrisp | Max Crisp, Air Fry, Air Roast, Bake, Reheat, Dehydrate |
| Main buying reason | Different portion sizes and compatible storage lids | Larger basket capacity and more modes |
What makes Crispi interesting?
The FN101ST set includes the heating pod, two differently sized glass containers, crisper plates, storage lids, and a container adapter. Its practical attraction is changing the vessel to suit the task and using compatible containers for storage.
That can suit one person’s lunch, smaller dinners, or a household that dislikes moving leftovers between cooking and storage containers. Think about the whole sequence: preparation, cooking, serving, cooling, storage, and washing. A workflow advantage matters only if you actually use it.
SharkNinja named Crispi as a driver of cooking and beverage category growth in its Q2 2026 results. That is a current market signal within its portfolio, not proof that it is the best air fryer or the highest-selling model across all brands.

When the larger AF181 basket makes more sense
The AF181 provides a 6.5-quart nonstick basket and six cooking functions. Its larger nominal capacity is the clearest distinction from the 4-quart Crispi vessel. It is worth investigating when your usual portions make a smaller vessel feel limiting.
Do not translate quart capacity directly into a guaranteed number of dinners. Food shape, desired airflow, and whether ingredients need room affect usable capacity. Compare your normal meal with the manufacturer’s cooking guidance, rather than choosing from a serving-count slogan.
The additional Roast and Dehydrate modes are useful buying reasons only if you expect to use them. If your routine is simply reheating snacks, more named modes alone may not justify buying a new appliance.

Glass versus nonstick: compare handling and care
Glass and a nonstick basket require different habits. The Crispi containers need careful handling, suitable storage, and attention to the manual’s heating and cooling instructions. A nonstick basket needs care that preserves its coating; check permitted utensils and cleaning methods.
Neither design makes cleanup disappear. Ninja describes dishwasher-safe accessories, but confirm instructions for each part. Keep electrical components out of water as directed. Check whether the washable pieces fit your dishwasher and whether you will be comfortable handwashing them when needed.
We are not making a blanket health or safety judgment about one material over the other. Choose from documented materials and care guidance, not a broad “toxin-free” marketing phrase.
Counter space is only half the storage question
Measure where you will cook and where you will store the appliance. The Crispi system includes several separate pieces; the AF181 has a larger basket assembly. Allow the operating clearance specified in each manual, plus space to move food safely.
If you plan to store Crispi meals in its containers, consider what happens when the container you want for cooking is already holding leftovers. Extra compatible glassware may be useful, but count that purchase before deciding the base set is better value.
Evaluate value using your actual week
Write down three recent meals you would use the appliance for. For each, identify the portion, the cooking vessel, the cleanup, and the job it would replace. This makes the decision more concrete than comparing promotional photos.
As a hypothetical example, a $180 purchase used four times weekly for two years costs about $0.43 per use before electricity, accessories, and repairs. Used once monthly over those two years, the purchase cost is $7.50 per use. These are illustrative numbers, not either model’s current price.
A sale is helpful only after the product fits. Compare equivalent colors and bundles, included containers or plates, new versus used condition, and return terms. Avoid buying extra accessories before discovering a real need.
Who should skip these models?
Keep your existing air fryer if it already handles your meals well. Consider another design if you regularly need two foods cooked at separate temperatures or a much larger serving area. These two models should not be presented as independent dual-zone systems.
If an oven already does the job conveniently, an additional appliance may add clutter rather than value. The strongest reason to buy is a recurring inconvenience it removes.
Our recommendation
Choose Crispi for the glass-container workflow and varying smaller portions. Choose AF181 for a larger single basket and additional modes. We would decide on meal size and handling preferences before paying extra for novelty.
