Compare Air Fryers
Livwell 6 Quart Glass Container Air Fryer scores higher on safety - here's why.
The most important dimensions, side by side.
Crisper plate base material not disclosed — full opacity penalty on primary food-resting surface. Cannot assess material safety without knowing what food contacts during cooking.
Aluminum without food-grade qualifier — unconfirmed whether anodized, treated, or raw. Raw aluminum can leach into acidic foods. Score 4 reflects disclosed material without food-grade certification.
No applied coating — no degradation pathway, no chemical migration, no PFAS risk. Bare borosilicate glass and bare 304/316 stainless are inherently food-safe at all cooking temperatures. Ideal per primary source hierarchy.
nano-ceramic: engineered nano-scale particles (1–100nm) have documented enhanced penetration risk under abrasion vs standard ceramic — SKL explicitly rejected Ninja Crispi for 'nano-ceramic with limited transparency'. proprietary-not-disclosed: 'nonstick' without coating name — cannot assess PFAS/PTFE content. Both score 1 per opacity principle.
food-grade-aluminum: FDA food-contact approved; softer than stainless, less thermal durability. glass-unspecified: brand says 'glass' without borosilicate/tempered/heat-resistant qualifier — food-safe material class but glass type unconfirmed. Both score 5: known safe material without grade/type confirmation.
All confirmed food-grade material families: borosilicate glass (chemically inert, heat-resistant), 304/316/18-8/18-10 stainless (FDA 21 CFR compliant, non-reactive, corrosion-resistant). Explicit grade confirmation required to score 10 — 'stainless' alone maps to score 8. Both families recommended by primary sources as safest available.
Brand self-reports PFAS-free or PTFE-free without naming a certifying body or publishing a test report. SKL: 'PFAS-free does not guarantee a product is completely non-toxic.' No evidentiary weight, but positive claim is better than silence.

Serious Eats 34-model test: square baskets 'consistently outperform round for crisping quality' — more surface area, better airflow. Glass-bowl-convection-rack provides 360° airflow. Both represent optimal cooking geometry.

Fastest preheat, strongest temperature maintenance. Tom's Guide top pick (Ninja Pro) at 1750W rated 'supremely powerful'.
Strong performance. RTINGS top-pick (DZ550) measured 1510W, scored 8.2 in air frying performance.

Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want an uncoated glass bowl air fryer -- the glass container itself has no applied coating and zero degradation risk.
You value a lifetime warranty (10-year proxy) from a brand that stands behind its product.
Dishwasher-safe glass container and basket make cleanup easy for daily use.
You trust Livwell's PFAS-free claim and accept that no independent lab has verified it.
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 crisper plate material -- the surface your food actually sits on -- is not disclosed by Livwell on any listing, product page, or manual. Despite the glass bowl being uncoated and inert, the undisclosed rack material makes it impossible to verify what food contacts during cooking. The brand claims PFAS-free but no third-party lab has verified it.
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 need to know exactly what material the crisper plate is made of -- Livwell does not disclose it.
You require UL or ETL safety certification -- none is disclosed for this product.
You want independently verified PFAS-free testing, not just a manufacturer claim.
You need a published max temperature specification -- none is available from any source.
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 Livwell 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 Livwell 6 Quart Glass Container Air Fryer uses a borosilicate glass basket with a not-disclosed crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the Livwell 6 Quart Glass Container Air Fryer (borosilicate glass basket, 4.9/10 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 Livwell 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.
