Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
Zero-coating, PFAS-free food-contact surfaces are your top priority.
You want glass bowl visibility and 360-degree convection cooking.
You accept the premium price and short warranty for material safety assurance.
You want borosilicate glass containers that are chemically inert and heat-resistant.
You accept nano-ceramic crisper plates as a compromise for the glass-bowl design.
The 62 dB noise level matters -- this is quieter than most air fryers on the market.
Dishwasher-safe glass containers and crisper plates simplify daily cleanup.
The main thing to know
The Fritaire achieves the highest safety score in this batch thanks to 304 stainless steel racks and zero coatings. The tradeoff: a 90-day warranty (well below the 1-year industry standard), no UL/ETL electrical safety certification, and a $200 premium price.
The borosilicate glass container is excellent, but your food rests on crisper plates coated with nano-ceramic -- engineered nano-scale particles that Sustainably Kind Living explicitly rejected for limited transparency. The crisper plate base is aluminum without a food-grade qualifier. SharkNinja claims PFAS-free and PTFE-free, but no independent lab has verified it.
Skip this if you...
You require UL/ETL electrical safety certification before purchasing any appliance.
A 90-day warranty on a $200 appliance is unacceptable to you.
You need dishwasher-safe cooking vessels for easy cleanup.
You want zero coating risk -- nano-ceramic has the same transparency concerns as undisclosed coatings per SKL.
You need independently verified PFAS-free testing, not just a manufacturer claim.
You want stainless steel crisper plates with no coating at all (e.g., Fritaire).
You require UL or ETL safety certification -- none is disclosed for this model.
Neither of these quite what you're looking for?
I've reviewed all Air Fryers options at every price pointEvery Air Fryers in our database is scored using R3's deterministic scoring system - the same inputs always produce the same score. For this comparison, we evaluated Fritaire and Ninja across 3 independent criteria: Safety (90%), Efficacy (7%), Usability (3%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
The Fritaire Non Toxic Air Fryer Pro, 9-in-1 Glass Air Fryer, Self-Cleaning uses a borosilicate glass basket with a stainless steel crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the Fritaire Non Toxic Air Fryer Pro, 9-in-1 Glass Air Fryer, Self-Cleaning (borosilicate glass basket, 8.4/10 safety) uses materials I'm more comfortable with at high heat. The Ninja Crispi 4-in-1 Glass Air Fryer's borosilicate glass basket scored 4.5/10. In our scoring system, basket material accounts for a significant portion of the safety pillar, which is our highest-weighted scoring factor.
For families, capacity comes first: check the capacity specs for your family size. Overall, I'd lean toward Fritaire for most families.
304 stainless steel is inherently PFAS-free and won't off-gas at any cooking temperature. Nonstick coatings (PTFE/Teflon) are stable below 400°F but can begin degrading above that threshold. In our scoring system, stainless and borosilicate glass baskets consistently score higher on the safety pillar. That said, a well-maintained nonstick basket from a reputable brand still meets safety baselines. It's a question of margin, not danger.
