Cons
- Premium pricing reflects the advanced glass construction and safety features, making it a significant investment compared to standard plastic air fryers

The Ninja Crispi Pro represents a significant evolution in air fryer design by prioritizing health and transparency. This glass-based system is built for families who cook in volume and want to eliminate exposure to PFAS, PTFE, and BPA found in traditional plastic air fryers. Whether you are meal prepping for a family of six, hosting dinner parties, or simply want healthier cookware, this modular system adapts to your needs.
The standout feature is the combination of thermal shock-resistant borosilicate glass and powerful 1800-watt performance. You can transfer frozen chicken directly from your freezer to the 6-quart container and have crispy results in minutes without thawing. The six cooking functions, from Max Crisp to Dehydrate, deliver professional-grade results for everything from weeknight proteins to homemade jerky and proofed bread. Temperature control is precise and consistent, ensuring reliable outcomes across different recipes.
Build quality is exceptional throughout. The modular stainless-steel base adjusts seamlessly between 2.5-quart, 4-quart, and 6-quart containers, meaning you invest once and scale up or down based on your meal. The snap-lock lids transform cooking containers into airtight storage solutions that go directly into your refrigerator, eliminating the need for separate meal prep containers. Heat-safe feet are permanently fixed, allowing safe placement on any countertop surface without trivets.
The primary consideration is the premium price point and physical footprint. The 6-quart capacity requires substantial counter and cabinet space, and glass containers demand more careful handling than plastic alternatives, though thermal shock resistance significantly reduces breakage risk. The investment is justified for health-conscious families prioritizing chemical-free cooking and long-term durability.
The Ninja Crispi Pro delivers exceptional value for families seeking a versatile, health-conscious cooking system that eliminates toxic coatings while providing restaurant-quality results. This is a premium appliance that justifies its cost through superior materials, thoughtful design, and genuine cooking versatility.

Buying Guide: What to Look For in a Ninja Air Fryer
Capacity and Cooking Versatility
The first factor to consider is how much food you typically prepare. The Ninja Air Fryer Pro 5 Qt holds up to 4 pounds of fries, making it ideal for couples or small families. If you often cook for gatherings or want to roast a whole chicken, the Ninja Crispi Pro 6-qt glass container feeds up to 10 people. The standard Crispi Glass model offers a 4-qt container for family meals and a 6-cup personal size for quick single servings. Think about your usual batch sizes before choosing.
Material and Safety
Ninja has introduced borosilicate glass containers in the Crispi and Crispi Pro models. These are free of PFAS, PTFE, and other chemical coatings, so you can cook and store food without worrying about toxins. The glass is thermal shock resistant, meaning you can take it straight from the freezer to the air fryer. The classic Ninja Air Fryer Pro uses a nonstick basket and crisper plate, which are dishwasher safe but rely on traditional coatings. If you prefer nontoxic cookware, the glass models are a clear advantage.
Functions and Presets
All three models offer at least four cooking functions. The Ninja Air Fryer Pro 5 Qt includes Air Fry, Roast, Reheat, and Dehydrate. The Crispi Glass adds Max Crisp, Bake, and Recrisp for a total of four modes. The Crispi Pro goes further with six modes: Max Crisp, Air Fry, Bake/Proof, Roast, Recrisp, and Dehydrate. If you bake bread or proof dough, the Crispi Pro is the only one with a proof setting. For most users, the standard four functions cover daily needs, but enthusiasts will appreciate the extra versatility.
Space and Storage
Counter space is precious in many kitchens. The Ninja Air Fryer Pro 5 Qt has a compact footprint and a vertical design that saves room. The Crispi models take a different approach: the PowerPod base nests inside the glass containers, so the whole system stores neatly in a cabinet. The Crispi Pro base adjusts to fit multiple container sizes, so you can scale up without buying a new appliance. If you hate cluttered counters, the Crispi line offers clever storage solutions.

After reviewing all three models, our top recommendation depends on your priorities. For a budget-friendly, no-fuss air fryer that delivers crispy results with minimal oil, the Ninja Air Fryer Pro, 5 Qt, 4-in-1, Grey, AF141 is a reliable workhorse. If you value nontoxic cookware and space-saving design, the Ninja Crispi Glass Air Fryer, 4-in-1, Stone offers a unique glass system that cooks, stores, and travels seamlessly. For larger families or those who want the most cooking functions, the Ninja Crispi Pro Glass Air Fryer, 6-in-1 is the ultimate choice. Whichever you pick, you will enjoy healthier meals without sacrificing flavor or convenience.
Frequently Asked Questions
Can I put glass containers from the freezer directly into the Ninja Crispi air fryer?
Yes, the borosilicate glass used in the Crispi and Crispi Pro is thermal shock resistant, so you can go straight from freezer to air fryer without thawing. This saves time and reduces dish use. Always check that the container is not chipped before use.
How does the Ninja Air Fryer Pro 5 Qt compare to the Crispi models in terms of cooking speed?
The Ninja Air Fryer Pro 5 Qt uses 1750 watts and Air Crisp Technology to cook food quickly. The Crispi Pro has 1800 watts, making it slightly more powerful for larger meals. The standard Crispi operates at around 1500 watts. In practice, all three cook frozen foods to crispy in minutes, but the Crispi Pro handles big batches faster.
Are the glass containers in the Crispi models dishwasher safe?
Yes, the CleanCrisp borosilicate glass containers, crisper plates, and snap-lock lids are all dishwasher safe. The PowerPod base should be wiped clean with a damp cloth. This makes cleanup effortless compared to traditional basket air fryers.
Which Ninja air fryer is best for a small kitchen?
If counter space is limited, the Ninja Air Fryer Pro 5 Qt has a slim vertical profile that fits easily. However, the Crispi models store the base inside the glass containers, so they take up almost no cabinet space when not in use. For a truly space-saving solution, the Crispi line is ideal.
