Compare Countertop Ovens
COMFEE Air Fryer Toaster Oven CFO-SA231 scores higher on safety - here's why.
The most important dimensions, side by side.
The oven interior is stainless steel — a bare metal that does not off-gas, chip, or degrade at any cooking temperature. This is the safest interior material available in countertop ovens.
The interior cavity uses galvanized (zinc-coated) steel rather than stainless steel. Health-focused reviewers flag this material for potential lead contamination concerns from the zinc coating, especially at high temperatures. The brand claims FDA compliance, but stainless steel interiors are considered safer.
Neither the brand nor any independent lab has verified this oven is free of PFAS chemicals. The stainless steel and enamel materials themselves are inherently PFAS-free by composition, but no one has formally tested or stated it.
HYSapientia has not made a formal PFAS-free claim or obtained independent testing for this product. The galvanized steel interior has no coating, so PFAS contamination is unlikely from the oven itself, but there is no verification to confirm this.
The included baking tray has an enamel coating — a glass-fused-to-metal surface that is naturally PFAS-free and will not leach chemicals into your food at any temperature.
The included baking tray is enameled iron, which is excellent for food safety. The enamel coating is completely inert -- no PFAS, no leaching risk, and it holds up at all oven temperatures. This is the surface your food will touch most directly.
At 24 quarts, this oven fits a 12-inch pizza, 6 slices of toast, or a 4-pound whole chicken. Solid for everyday family cooking but not large enough for a small turkey.
At 26 quarts, this oven fits a whole chicken comfortably and supports multi-tier cooking with three rack heights. It is one of the larger countertop ovens available.
Ten distinct cooking modes cover virtually every need: air fry, air roast, broil, sear crisp, rapid bake, pizza, bagel, toast, reheat, and dehydrate. This matches premium ovens costing significantly more.

The crumb tray slides out for easy cleaning, preventing buildup that could cause smoke or affect food taste.

At $210, this oven is competitively priced for a 10-function countertop oven with stainless steel interior and enamel accessories. The value score reflects a technical gap in our calculation, not the actual purchase value.
The value ratio could not be calculated for this product. At $149.99, this is a competitive price for a full-featured 26-quart countertop oven with rotisserie.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want a versatile 10-function countertop oven that handles everything from air frying to dehydrating.
A stainless steel interior and enamel-coated tray matter more to you than formal PFAS certification.
You cook for a family of 3-4 and need a 24-quart oven that fits a 12-inch pizza or whole chicken.
Fast preheating is important — the FLASHWAVE graphene elements heat in 0.2 seconds.
You always cook on the included enameled iron baking tray and never place food directly on the oven walls.
You want a large 26-quart countertop oven with rotisserie for under $150.
You value cooking versatility with 10 functions including dehydrate and rotisserie.
You prefer a stainless steel exterior over plastic for countertop durability and appearance.
The main thing to know
No one — not the brand, not a lab, not any certifier — has tested or even claimed this oven is free of PFAS. The materials themselves (stainless steel, enamel) suggest low risk, but the complete absence of verification is the single biggest score penalty.
The oven cavity is galvanized (zinc-coated) steel, which health-focused reviewers flag for potential lead contamination risk at high temperatures. The baking tray is safe enameled iron, but the interior walls your food heats near are not stainless steel.
Skip this if you...
You require independent PFAS-free verification or NSF certification on your cooking appliances.
You need a confirmed food-grade stainless steel interior — the stainless steel claim is inferred from the product title, not manufacturer-confirmed for the cavity.
You want a larger oven for small turkeys or large roasts — 24 quarts tops out at a 4 lb chicken.
You want stainless steel food-contact surfaces throughout the entire oven cavity, not just the baking tray.
Independent PFAS testing or material safety certification is a requirement before you buy a cooking appliance.
You are uncomfortable with galvanized steel as an oven interior material given the lead contamination concerns raised by safety advocates.
Neither of these quite what you're looking for?
