Compare Air Fryers
Livwell 6 Quart Glass Container Air Fryer scores higher on safety - here's why.
The most important dimensions, side by side.
The crisper plate base is bare aluminum without food-grade certification. Scores 4/10.
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.
Ceramic nonstick coating explicitly marketed as PFAS-free. But ceramic coatings can chip and degrade over time.
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.
The basket is bare aluminum. Source says aluminum without food-grade qualifier.
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.
Cosori explicitly claims PFAS-Free Ceramic Coating on this model. No independent lab has verified this, but it is a stronger claim than the Pro LE which only claims PFOA-free.
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.
Square basket design for optimal crisping and airflow.
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.
At 1725 watts with DC motor, this is the most powerful air fryer in the lineup. Fast preheat and excellent temperature recovery.
Fastest preheat, strongest temperature maintenance. Tom's Guide top pick (Ninja Pro) at 1750W rated 'supremely powerful'.
Full temperature adjustability from 90 to 450 degrees F.
band_boolean:null→5
Both basket and crisper plate are dishwasher safe.
band_boolean:true→10
Less than 53 dB even on highest fan speed -- among the quietest basket-style air fryers.
band_range:null→5
2-year limited warranty from Cosori.
≥3 years: uncommon — signals manufacturer confidence in durability.
Good value at $99.99 for a high-wattage 6-quart air fryer.
$161–300: premium range.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the strongest cooking performance available -- 1725W TurboBlaze with DC motor.
Quiet operation matters -- less than 53 dB even on the highest fan speed.
You want an explicit PFAS-free claim from a well-known brand and are comfortable with manufacturer self-reporting.
You cook for three to five people and want a 6-quart, dishwasher-safe, square-basket design with a 2-year warranty.
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.
The main thing to know
The PFAS-Free Ceramic Coating is a manufacturer marketing claim -- no independent lab has tested or certified it. The food-contact surfaces are ceramic-coated bare aluminum, and the ceramic coating introduces a degradation pathway absent in uncoated surfaces. Both basket and crisper plate are aluminum without food-grade certification.
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.
Skip this if you...
You want uncoated food-contact surfaces -- look at glass or bare stainless steel air fryers instead.
You require third-party PFAS-free verification (NSF 537 or lab testing), not just a manufacturer claim.
You prioritize material purity above all else -- the ceramic-coated bare aluminum design scores below average on safety.
Budget is a concern -- at $99.99, other models offer better material safety at similar or lower prices.
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.
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 Cosori and Livwell across 3 independent criteria: Safety (90%), Efficacy (7%), Usability (3%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
The Cosori 9-in-1 TurboBlaze Air Fryer 6 Qt uses a bare-aluminum basket with a bare-aluminum crisper plate. PTFE-coated nonstick may contain trace PFAS compounds, which is reflected in its 4.3/10 safety score in our scoring system. For a PFAS-free alternative, look for models with stainless steel or borosilicate glass baskets.
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 Cosori 9-in-1 TurboBlaze Air Fryer 6 Qt's bare-aluminum basket scored 4.3/10. 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: Cosori offers 6-qt vs Livwell's 6-qt. 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.
