For anyone with a Cosori, the accessory I'd reach for first is the Geolinhome Air Fryer Rack — a three-tier 304 stainless steel set that turns one cooking zone into three, and the single biggest upgrade you can make to a machine that only came with one basket.
• Geolinhome Air Fryer Rack — best for batch cooking and dehydrating in one go; pick this if you want three stackable 304 stainless steel layers that maximize the space your Cosori already has.
• DOMEM Air fryer Basket — best for replacing a worn or missing basket and adding a handle; pick this if your square Cosori has an inner width above 8.5 inches and you want a single mesh basket that doubles as a steamer.
• ZEENEEK 8 — best for a complete stacked-cooking kit; pick this if you want three removable racks plus anti-scald clips so you can pull hot layers out safely.
• HLEIUKT Hot Air Fryer — best for baking, cakes and messy foods; pick this if you'd rather line your Cosori with reusable silicone than keep buying disposable paper.
This is a three-piece set of square stainless steel mesh racks that stack on top of each other inside the air fryer. Each layer measures roughly 8.19 to 8.27 inches square and stands about 3.54 inches tall, and the set is built from polished, food-grade 304 stainless steel. The idea is simple: instead of cooking one layer of wings at the bottom of your Cosori basket, you cook three layers at once.
The design detail that matters most is the support legs. They hold each rack above the one below so hot air can move up through the mesh rather than being blocked by a solid tray. In practice that means a tray of vegetables on the bottom, chicken on the middle and something quicker on top can all cook in the same cycle, with the mesh letting the air reach every piece. For anyone who regularly cooks for more than one person, that's the difference between two rounds in the air fryer and one.
The mesh openings are also small enough that they're genuinely useful for dehydrating. Sliced fruit, vegetable chips and jerky-style strips sit on the mesh without dropping through, which is why I think of this as the batch-cooking pick rather than a single-purpose rack. Cleanup is straightforward — it's dishwasher safe, and the polished finish means most residue rinses off before it even goes in.
The trade-off is fit. At around 8.2 inches square and over 3.5 inches tall per layer, this needs a reasonably large square Cosori to stack all three without touching the heating element. Geolinhome itself says to measure your tray before buying, and I'd take that seriously — in a smaller basket you'll likely use one or two racks rather than the full stack. It's also a set of racks only, so it replaces nothing you already own; it adds capacity to a basket you keep using.
DOMEM Air fryer Basket
The DOMEM basket is a different kind of accessory. It's a single square mesh basket, 8.19 x 8.19 x 2.8 inches, designed to sit inside a square air fryer with an internal width above 8.5 inches. DOMEM lists it as compatible with the Cosori 5.8QT, the Instant Vortex 6qt and Vortex Plus 6qt, and the Philips XXL HD9650 and HD9630, among other square models.
It's also more versatile than the name suggests. DOMEM positions it as both a fryer basket and a steamer basket, and the 304 stainless steel construction is rust-resistant, which matters for something that lives in a damp kitchen and gets washed constantly. Whole chicken, steak, vegetables, snacks and desserts are all fair game. It's dishwasher safe, though DOMEM notes that stuck-on food benefits from a soak first — worth knowing before you assume it's a wipe-and-go item.
The trade-off is that this is one layer. You get a better basket, not more capacity, so if your goal is cooking three times as much food at once, the stackable sets will serve you better. And compatibility is specific: it wants a square fryer with an inner dimension above 8.5 inches, so a round or unusually narrow Cosori is the wrong home for it. Weigh it at 7.8 ounces, it's light enough that it won't meaningfully change how your drawer sits, but it also won't feel like heavy-gauge cookware.
ZEENEEK's offering is the most complete stacked-cooking kit of the four. It's a set of three removable square racks in 304 food-grade stainless steel — rustproof, high heat resistant and dishwasher safe — and the listing describes it as 13 pieces, which points to the extras bundled alongside the racks.
Those extras are the interesting part. The anti-scald clips are silicone and stainless steel with a non-slip texture, and they exist for one reason: pulling a hot rack out of a hot air fryer without burning your fingers. If you've ever tried to retrieve a middle layer with a fork, you'll understand why I rate that inclusion. Each rack measures about 8.27 inches square and only 0.63 inches tall, so the stack is thin and low rather than bulky.
The layered design is aimed at families. ZEENEEK's pitch is that you can run one, two or three racks depending on the job, with enough room for fried food, dehydrated fruit, meat, vegetables and baked treats. The mesh is sized to keep food from falling through, and the spacing between layers is intended to stop flavours and textures from merging — so a batch of chicken nuggets and a batch of veg don't end up tasting like each other.
The trade-off is that thin racks trade sturdiness for stackability. At 4 ounces per rack, these are light inserts, not heavy pans, so you'll want to load them sensibly rather than piling on a dense roast. And like the Geolinhome set, this adds capacity without replacing anything, so it's an addition to your kit rather than a fix for a broken basket.
HLEIUKT Hot Air Fryer
The HLEIUKT set is the odd one out here, and that's exactly why it earns a place. Instead of steel mesh, it's built around food-grade silicone: a one-piece mould, a 2-in-1 mould, a baking rack, five kebab skewers, a silicone toast box, a classic bundt cake mould, six silicone cake moulds, a pizza pan and silicone tongs.
The material is the whole story. The silicone is non-stick, odourless, grease-repellent and BPA-free, heat resistant up to 230°C, and designed as a reusable replacement for disposable baking paper. If you bake in your Cosori — cakes, muffins, small loaves — paper liners are fiddly, they curl, and they block airflow at the base. A mould that holds its shape solves all three problems at once.
The 2-in-1 design is the feature I'd highlight. It lets you cook two different dishes simultaneously without the aromas crossing over, and the one-piece insert is sized for whole chickens and other large items. That's a genuinely useful trick in an air fryer, where a single drawer usually means one flavour profile per cycle.
Compatibility is the widest of the four, but also the most specific. HLEIUKT says the moulds suit square air fryers of 20–24 cm, covering 4.7–8L machines, and names the Cosori 4.7L, 5.5L, 6L, 6.2L and 6.4L alongside Philips, Cecotec, Ninja and Russell Hobbs models. The trade-off is twofold: silicone doesn't deliver the same hard sear or crisp edge that a bare metal rack does, so it's a baking and messy-food tool rather than a crisping one. And with this many pieces, storage becomes a real consideration — you'll want a drawer or box for the moulds you're not using that week.
How We Picked
We compared the published specs and features of each set — materials, dimensions, layer count, compatibility ranges and what's actually in the box — and judged them against the jobs Cosori owners most often want to do: cook more at once, replace a basket, stack safely, and bake without paper. The ranking is our independent editorial opinion, based on those specs and everyday use cases rather than hands-on testing. No brand paid for placement or had any input into the order.
It depends on which Cosori you own. The stackable racks want a square basket roughly 8.2 inches across; the DOMEM basket wants an inner width above 8.5 inches; the HLEIUKT silicone set targets 20–24 cm square fryers in the 4.7–8L range, including several Cosori sizes. Measure your basket before ordering.
They do different jobs. Steel mesh racks maximize airflow for crisping, roasting and dehydrating, while silicone moulds are better for batters, cakes, eggs and anything that would run through a mesh. Many Cosori owners end up with one of each.
Only if your air fryer is tall enough. Each layer adds height, and the racks need clearance from the heating element. In a large square Cosori you can often run the full stack; in a smaller one, one or two layers is more realistic.
The Geolinhome racks, DOMEM basket and ZEENEEK racks are all listed as dishwasher safe. The HLEIUKT silicone set can be washed by hand or in the dishwasher, and its soft material turns inside out easily for cleaning.
