• WERTGHJ biggest strength: A large 37 × 34 × 29 cm glass body with a 90° wide cover and a thickened anti-scald handle, so loading and checking food is genuinely easy.
• WERTGHJ biggest trade-off: Its glass build and bigger frame take up more counter space and need more careful handling than a small metal unit.
• UOHLCX biggest strength: 3D hot air circulation heating in a "small stature with large capacity" stainless steel shell, plus a straightforward knob control.
• UOHLCX biggest trade-off: The compact footprint means less room for big batches, and its feature list is leaner.
• Who WERTGHJ is for: Cooks who want visibility, a wide opening and a glass chamber they can wipe down.
• Who UOHLCX is for: Cooks who want a space-saving stainless unit with even, circulated heat and no learning curve.
The WERTGHJ Air Fryer Oven is built around access and visibility. The 90° wide cover opens far enough that you can slide food in and out without wrestling with a tight basket, and the thickened anti-scald handle means you grab a cool-to-touch surface rather than a hot edge. The body is glass, and the non-stick coating on the cooking surface is described as easy to clean, oil-free and worry-free — which matters, because the single biggest driver of lingering air fryer smell is old oil and food residue baking onto surfaces you can't reach.
Think about who actually benefits. If you cook chicken legs, meat dishes, fish or seafood, you're generating the kind of spattery, aromatic grease that leaves a smell behind. A glass chamber you can see through and wipe down, with removable baskets, racks and tools that clean by hand or in the dishwasher, is a real advantage here. The multidimensional heat dissipation holes are another point in its favor for odor management: they give hot, greasy air somewhere to vent rather than trapping it inside the shell.
The trade-offs are honest ones. At roughly 37 × 34 × 29 cm, this is not a tucked-away appliance — it wants real counter space. It runs on 220V at 1350W, so confirm your outlet and kitchen setup match before buying. And if you mainly reheat small portions for one person, the capacity here is more than you need. Skip it if you want something you can stash in a cupboard between uses; buy it if you want a glass-front oven you can see into and clean easily.
The UOHLCX Air Fryer Oven takes the opposite approach: it does more with less space. The headline feature is 3D hot air circulation heating, which moves hot air around the food from multiple directions instead of relying on a single blast. That's the design choice most directly tied to crispiness without deep frying — the stainless steel build is described as producing extra-crispy meals with a fraction of the calories compared to oily, messy deep fryers.
Its second strength is the control scheme. A knob control keeps things dead simple, and the unit covers Air Fry, Bake and Reheat, plus a function that defrosts and then crisps for added crunch on fries or mozzarella sticks. There's also an anti-scalding handle and a defined heat dissipation hole position, so the venting is placed deliberately rather than wherever it fit. "Small stature with large capacity" is the pitch, and at 28 × 23 × 28.8 cm it's meaningfully more compact than the WERTGHJ.
Who should buy it? Anyone with a tight counter or a small kitchen who still wants bake, reheat and air-fry in one box. The stainless steel surface is also easier to wipe down than a glass shell in some ways — no seams or transparent panels to streak. Who should skip it? If you regularly cook for a family, the compact body will feel limiting, and if you want to watch your food through a window, this isn't that machine. It's also 220V at 1350W, same as the WERTGHJ, so the electrical requirement is a wash. In my opinion, this is the better pick for a single cook or a couple in a small space.
Side-by-Side: Which Should You Choose?
• Best for easy loading and visibility → WERTGHJ Air Fryer Oven. The 90° wide cover and glass body let you see and reach your food without guesswork.
• Best for small kitchens → UOHLCX Air Fryer Oven. At 28 × 23 × 28.8 cm it's the more compact of the two.
• Best for even, circulated crisping → UOHLCX Air Fryer Oven. 3D hot air circulation is the core of its cooking design.
• Best for odor control through design → WERTGHJ Air Fryer Oven. Multidimensional heat dissipation holes plus a wipe-clean non-stick surface give grease and smell fewer places to hide.
• Best for big-batch cooking → WERTGHJ Air Fryer Oven. Its larger frame and wide opening suit chicken legs, meat dishes, fish and seafood.
• Best for defrost-then-crisp convenience → UOHLCX Air Fryer Oven. Its dedicated sequence takes frozen fries or mozzarella sticks straight to crunchy.
• Best for a stainless steel finish → UOHLCX Air Fryer Oven. Metal body, easy to wipe, no glass panels to clean.
If I were buying for a small kitchen and mostly cooking for one or two, I'd take the UOHLCX Air Fryer Oven. The 3D hot air circulation, the compact frame and the no-nonsense knob control line up with how most people actually use an air fryer day to day. That said, if your priority is seeing your food, loading a big batch without a fight, and having a surface you can scrub clean to keep cooking smells from building up, I'd go with the WERTGHJ Air Fryer Oven instead. Both are 220V, 1350W units, so the real decision is size and access versus circulation and simplicity. Check the current price on Amazon for whichever one fits your counter.
how to get new air fryer smell out
A brand-new air fryer often carries a manufacturing residue that burns off in the first few uses. Run it empty at its normal setting for about 10–15 minutes in a ventilated kitchen, then wipe the interior with warm soapy water and let it dry fully before cooking. Doing this once up front prevents that plastic-and-metal odor from settling into your first meal.

Ventilation does most of the work. Run the unit under a hood or near an open window, and use the machine's heat dissipation holes to let greasy air escape rather than recirculate. Wiping the basket and interior after every session — easier on a non-stick surface like the WERTGHJ's — stops residue from baking on and re-releasing odor the next time you cook.

The smell usually lives in old oil and food particles, not the appliance itself. Clean the basket, racks and removable tools after each use — the WERTGHJ's parts are dishwasher-safe, which makes this painless — and check the heating element area for splatter. Let everything dry completely before storing, since trapped moisture and grease is what turns a faint cooking smell into a persistent one.
how to make air fryer smell better
Keep it clean first, then cook smart. Lining the basket, emptying grease promptly and running a short empty cycle with a slice of lemon or a splash of vinegar in a heat-safe dish can freshen the chamber. Both the WERTGHJ and UOHLCX run at 1350W, so a brief low-load cycle is enough to clear mild odors without overworking the unit.
