Compare Air Fryers
Granitestone Big Boss 16Qt Large Glass Air Fryer scores higher on safety - here's why.
The most important dimensions, side by side.
The crisper plate is aluminum without a confirmed food-grade certification. Coating (PTFE) is scored separately.
The racks are stainless steel but the specific grade (304, 316, 18/8) is not disclosed. Likely food-safe but unconfirmed.
PTFE (Teflon) nonstick coating confirmed via California AB 1200 mandatory chemical disclosure. Degrades above 500F.
Glass bowl and bare stainless steel racks -- nothing to chip, flake, or degrade.
The basket body is aluminum. Amazon lists 'Aluminum' without food-grade qualifier.
The glass bowl is tempered glass. Food-safe but less chemically inert than borosilicate glass.
This product contains PFAS per Dash's own California AB 1200 disclosure. No PFAS-free verification exists.
Granitestone claims the product is free of Teflon and forever chemicals. Glass + stainless inherently lack PFAS, but no third-party testing published.
Round baskets crowd food and produce less even crisping than square designs.
Glass bowl with halogen, convection, and infrared heating provides 360-degree cooking.
At 1000 watts, this air fryer is underpowered. Preheating is slow and temperature drops significantly when the basket opens.
At 1300 watts, preheating is slower than higher-wattage competitors.
Both the crisper tray and drawer are dishwasher safe.
All removable parts including the glass bowl go in the dishwasher.
Standard 1-year warranty. Extended to 2 years with Feel Good Rewards registration.
Standard 1-year limited warranty.
Under $60 makes this one of the most affordable air fryers available.
$129.99 for 16 quarts of zero-coating glass + stainless steel cooking.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You need a compact, budget air fryer under $60 for personal portions.
PTFE coating is acceptable to you and you want dishwasher-safe convenience.
You cook small portions (2.6 qt capacity) and want 400F max temp.
You want a large-capacity (16 qt) glass air fryer with zero coatings at a mid-range price.
Dishwasher-safe parts (including the glass bowl) matter for easy cleanup.
You want the glass bowl convection cooking experience with halogen + infrared.
The main thing to know
PTFE (Teflon) coating confirmed on all food-contact surfaces via California AB 1200 mandatory disclosure. PTFE is itself a PFAS compound. No safety certification (UL/ETL) disclosed. Crisper plate and basket are bare aluminum without food-grade qualifier.
The Granitestone Big Boss uses tempered glass and stainless steel racks with zero coatings -- strong material safety. The stainless steel grade is unconfirmed (generic, not 304). ETL certification is referenced in Amazon text but not independently verified.
Skip this if you...
You want PFAS-free or PTFE-free food-contact surfaces -- consider the ceramic variant DCAF26CM instead.
You need to cook for a family -- 2.6 qt is personal-size only.
You require independently verified safety certifications (UL/ETL).
You need confirmed 304 or 316 stainless steel on food-contact surfaces.
You want independent PFAS verification beyond manufacturer claims.
You need independently confirmed UL/ETL certification.
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 Dash and Granitestone across 3 independent criteria: Safety (90%), Efficacy (7%), Usability (3%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
The Dash Tasti-Crisp Electric Air Fryer DCAF260 uses a bare-aluminum basket with a bare-aluminum crisper plate. PTFE-coated nonstick may contain trace PFAS compounds, which is reflected in its 3.0/10 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 Granitestone Big Boss 16Qt Large Glass Air Fryer (borosilicate glass basket, 7.7/10 safety) uses materials I'm more comfortable with at high heat. The Dash Tasti-Crisp Electric Air Fryer DCAF260's bare-aluminum basket scored 3.0/10. 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 Granitestone 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.
