Crispi Glass Air Fryer
Borosilicate-glass cooking containers with no PTFE - but food still sits on a nano-ceramic-coated aluminum crisper plate, so it is not fully coating-free.
Plastic-free verdict: Minimal plastic contact
The CleanCrisp glass containers are borosilicate and marketed by Ninja as free of PFAS and PTFE - a real step up from a Teflon basket. The honest catch is the crisper plate that food actually rests on: it is a nano-ceramic (sol-gel) coated aluminum plate, not bare glass or stainless. That coating is PTFE/PFAS-free but is still a proprietary applied coating in direct food contact, so we rate it minimal-contact - the same treatment we give ceramic-nonstick cookware, not plastic-free.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| cooking container CleanCrisp borosilicate glass; brand states free of PFAS/PTFE | Borosilicate Glass | Yes |
| crisper plate nano-ceramic (sol-gel) coating over aluminum per SharkNinja support; PTFE/PFAS-free but still an applied coating | Ceramic Nonstick (sol-gel coating) | Yes |
| PowerPod housing heating unit that sits above the container | Plastic (other / unspecified) | No |
The Crispi is Ninja's answer to the coating backlash: a palm-sized heating "PowerPod" that drops onto borosilicate glass containers, marketed as nontoxic and free of forever chemicals. The glass itself is genuinely coating-free and inert. But the piece food sits directly on - the crisper plate - is coated aluminum, described by SharkNinja as a nano-ceramic surface and by independent reviewers as a sol-gel "quasi-ceramic" coating. It is PTFE/PFAS-free, so it clears the worst of the air-fryer problem, but it is not the bare-glass-and-steel setup the marketing implies. Good if you want the glass form factor and accept a ceramic coating on the plate; if you want zero coating, the Fritaire (glass bowl, stainless accessories) or an oven-with- stainless-tray route is cleaner.
Pros

Cons
- Crisper plate food rests on is ceramic-coated aluminum, not bare
- The "ceramic" coating is an undisclosed sol-gel formula, not solid ceramic
- PowerPod is plastic-bodied (not in food path)
- Small capacity per container
