• Turbokey Round Barbecue Wire — biggest strength: a 9.5" round 304 stainless rack with a tight 1/2" mesh, rated to handle up to 1470°F, so it moves from oven to grill to pressure cooker without complaint. Biggest trade-off: it only fits if your cooker or grate has a full 9.5" of usable interior diameter, and it is the heavier of the two at 7.2 ounces.
• TOPPERFUN Stainless Steel Air — biggest strength: a square 8.07" x 8.07" x 1.77" stainless rack explicitly designed as a stackable air fryer layer for grilling, steaming and dehydrating. Biggest trade-off: the smaller footprint and thinner build (3.36 ounces) mean less usable surface and no stated high-heat ceiling.
• Pick Turbokey if you cook in a pressure cooker, on a grill, or in a full-size oven and want one rack that does all three.
• Pick TOPPERFUN if your priority is layering food inside an air fryer basket and you want a lightweight square rack that stacks.
• Both are 304 stainless steel with a silver finish and easy-clean surfaces, so the real decision comes down to shape and footprint, not material.
The Turbokey Round Barbecue Wire is the more serious piece of hardware of the two. It's a 9.5" (24cm) round rack made from 304 stainless steel with the joints spot welded, which is the detail that matters most for anything that lives near heat and moisture. The mesh opening is 1/2" (1.2cm), and that tighter weave is the whole point: small enough that nothing small slips through, dense enough that the rack holds its shape under a heavy piece of meat instead of sagging between supports.
Where it earns its place is versatility. The 1470°F (800°C) heat rating means it's genuinely oven safe and grill safe, so you can use it as a grill net over a fire pit for beef, chicken, fish or vegetables, as a cooling rack on the counter, as a steaming insert in a pressure cooker or Instant Pot, or sitting in a baking dish to lift food out of its own juices. The description also lists leg heights of 3/4 inch (1.9cm) and 1-3/4 inch (4.5cm) across the range, and fourteen size options overall — so this specific 9.5" version is one entry in a broader family rather than a one-off.
Who should buy it: anyone cooking in a pressure cooker, Instant Pot, or on a grill who wants one rack that crosses over between appliances. The no-rust claim is grounded in the 304 steel and welded joints, and the rack can sit in plenty of water for steaming without corroding — that's a real advantage over cheaper painted or coated racks.
TOPPERFUN Stainless Steel Air: Who It's For
The TOPPERFUN Stainless Steel Air is built around a different job. It measures 8.07" x 8.07" x 1.77" (20.50 x 20.50 x 4.50cm) — square, not round — and the manufacturer describes it as specifically designed to fit air fryers, with stacking as one of its four stated uses alongside grilling, steaming and dehydrating. That square footprint is not an accident: air fryer baskets are typically square or rounded-rectangular, and a square rack uses that space far more efficiently than a circle does.
At 3.36 ounces it's less than half the weight of the Turbokey, which tells you something about the gauge of the steel. That's a trade-off worth naming: lighter usually means thinner wire and a rack that flexes more under load. In practice that's fine for a layer of wings, vegetables, or a dehydrating tray, and less ideal if you're planning to rest a heavy roast on it.
The "stackable dehydrating layer" feature is the real selling point. If you've ever tried to cook a full basket of food in one flat layer, you know the frustration — you either crowd the basket and steam everything instead of crisping it, or you cook in two batches and double your time. A stackable rack lets you put a second level in and cook more at once. The listing also flags easy-clean and sturdy build, and the material is 304 stainless with a silver finish, so it holds up the same way the Turbokey does in terms of corrosion resistance.
Who should buy it: air fryer owners who regularly cook for two or more people and want to stop running back-to-back batches. It's also the better fit if your appliance is on the smaller side, since the 8.07" square will drop into baskets where a 9.5" round simply won't go.
Who should skip it: anyone who needs a rack for a pressure cooker or a full-size grill grate. The square shape and small footprint aren't designed for that, and the listing doesn't state a maximum temperature, so I wouldn't treat it as a grill-rated piece the way I would the Turbokey.
• Best for air fryer multi purpose rack use → TOPPERFUN Stainless Steel Air. Its whole design brief is air fryer layering, stacking and dehydrating.
• Best for grilling over fire or on a grate → Turbokey Round Barbecue Wire. The 1470°F rating and 1/2" mesh are built for direct heat.
• Best for pressure cookers and Instant Pots → Turbokey Round Barbecue Wire, provided you measure first and confirm 9.5" of usable interior diameter.
• Best for small air fryer baskets → TOPPERFUN Stainless Steel Air. At 8.07" square it fits spaces the 9.5" round rack can't.
• Best for heavier loads → Turbokey Round Barbecue Wire. 7.2 ounces of spot-welded 304 steel versus 3.36 ounces.
• Best for cooking more food in one go → TOPPERFUN Stainless Steel Air, because stacking is a stated design feature rather than a workaround.
• Best for someone who wants one rack for everything → Turbokey Round Barbecue Wire. Oven, grill, steamer and cooling rack in a single round piece.
• Best for a first air fryer accessory → TOPPERFUN Stainless Steel Air, since it's the more targeted fit and the lighter, simpler add-on.
In my opinion, the TOPPERFUN Stainless Steel Air is the better buy for most people searching for an air fryer multi purpose rack — it's designed for exactly that job, the square footprint fits more baskets, and stacking genuinely changes how much you can cook at once. I'd choose the Turbokey Round Barbecue Wire instead if you own a pressure cooker or grill and want one rack that crosses over between them, since the 1470°F rating and 9.5" round build make it the more capable piece of hardware. Buy the Turbokey for heat and versatility; buy the TOPPERFUN for air fryer layering and fit. Check the current price on Amazon for both before you commit, since the gap between them is worth weighing against how you actually cook.
how to use multi layer rack in air fryer
Set the rack flat in the basket, put food on the lower level, then place a second stackable rack on top and load that too. The TOPPERFUN Stainless Steel Air lists stacking as a designed use, so it's the more natural fit for this. Leave gaps around the edges so hot air can still circulate.
how to put rack in air fryer
Lower it in flat with the legs pointing down so the basket floor stays clear and air moves underneath. Measure your basket first — the Turbokey Round Barbecue Wire needs a full 9.5" of usable interior diameter, while the TOPPERFUN is an 8.07" square that fits smaller baskets.
can you use an air fryer without the rack
Yes. A rack is an accessory, not a requirement — you can cook directly on the basket floor. What the rack buys you is airflow underneath the food and, with a stackable design like the TOPPERFUN, a second cooking level so you're not crowding everything into one layer.
can you stack racks in an air fryer
Yes, if the rack is designed for it. The TOPPERFUN Stainless Steel Air is explicitly built as a stackable layer. Don't stack so high that you block the heating element or block airflow, and keep heavier food on the lower level so nothing tips.
