Instead of a metal basket, the Ninja Crispi clamps a palm-sized PowerPod onto borosilicate glass containers — a 4-quart and a 6-cup size come with the standard set. Ninja states both containers are free of PFAS, PTFE and nonstick chemical coatings. This review is research-based, using Ninja’s own product documentation rather than a hands-on lab test.

What it does well
The PowerPod nests inside the glass containers for storage, and it works with both the 4-quart and 6-cup sizes via an adapter, so one small motor unit covers cooking for one person or a small family. The glass containers double as leak-proof storage with their snap-lock lids, and both containers are dishwasher safe.
Where it falls short
At 4 quarts, the main container is moderate for larger families, and the pod-style format costs more than a comparable basic basket model. If you need bigger single-container capacity in the glass format, the Crispi Pro’s 6-quart container is the step up.

How it fits in the Ninja lineup
The standard Crispi sits below the larger-container Crispi Pro and the two-basket Crispi DualZone. See our Crispi vs Crispi Pro comparison, or best glass air fryer for glass picks across brands.
Buy it if / Skip it if
Buy it if you specifically want a coating-free glass cooking vessel and cook mainly for one to two people.
Skip it if you regularly cook larger batches — the Crispi Pro’s 6-quart container or a traditional basket model will serve you better.
Frequently asked questions
Is the Crispi’s glass actually coating-free? Ninja states the CleanCrisp glass containers are free of PFAS, PTFE and nonstick chemical coatings — this is the maker’s claim, not our independent lab measurement.
Can I use just the 6-cup container on its own? The PowerPod is designed to work with either included container via an adapter, so yes, for smaller portions.
How is this different from the Crispi Pro? The Pro steps up to a 6-quart main container and higher wattage. See our Crispi vs Crispi Pro comparison for the full breakdown.
Final verdict
For one to two people who specifically want to avoid a traditional nonstick basket, the Crispi’s glass-and-PowerPod format is a genuinely different approach worth considering. For larger households, size up to the Crispi Pro or a standard basket model instead.
