• Flylin's biggest strength: three stackable 304 stainless steel layers that create vertical space for dehydrating, draining and dry-and-crisp cooking — no coating to wear out.
• Flylin's biggest trade-off: it is a rack, not a plate, so it fits by shape and cavity depth rather than by round diameter, and it gives you no nonstick surface or brush.
• HERCHR's biggest strength: a perforated round replacement tray designed to drop into a round air fryer cavity, with a nonstick coating, eight anti-slip feet, a handle and a silicone oil brush in the same package.
• HERCHR's biggest trade-off: the nonstick layer needs gentler handling — no abrasive pads or metal scouring balls — and a round plate has no stackable storage function.
• Choose Flylin if you want more usable layers inside the basket, or you want the rack to double as a draining and storage rack outside the air fryer.
• Choose HERCHR if you want a simple one-piece cooking surface that drains oil, sits still in the basket and comes with a brush for oiling or saucing food.
Flylin's rack is best understood as a space multiplier. It is one unit made of three detachable layers, each built from 304 stainless steel that has been hand-polished so the edges are smooth rather than sharp. The mesh is uniform, which keeps food from sticking to it, and the material is described as both high-temperature resistant and corrosion resistant. In practical terms, that means you can put it in a hot air fryer basket or on a grill without worrying about a coating blistering or flaking — because there is no coating to begin with.
The whole rack measures roughly 7.4 inches deep, 4.7 inches wide and 4.5 inches high, and it weighs a little under twelve ounces. That footprint is compact enough to sit on a crowded counter, and the stackable design is the point: instead of laying a single layer of vegetable slices across the bottom of the basket, you spread them across three levels. For dehydrating fruit slices, jerky strips, herbs or vegetable chips, that is a real difference in how much you can process in one go. The description also calls out thawing and draining, and the multi-layer structure lets liquid fall through instead of pooling around the food, which is what keeps things crisp rather than soggy.
Flylin says the rack mounts to the Instant Pot Vortex and to air fryers or the Ninja Foodie Grill. I would treat that as a starting point rather than a guarantee — before buying, check your basket's interior dimensions against that 7.4 x 4.7 x 4.5 inch envelope, because a rack that is too tall will not let the basket close and one that is too wide will not sit flat.
Who should buy it? Someone who already uses their air fryer for more than reheating — drying apple rings, crisping chickpeas, resting fried food on a draining layer, or smoking and grilling. The removable layers come apart for sink or dishwasher cleaning, and the same rack works as a household storage and draining rack for fruit and vegetables, so it earns counter space even when the air fryer is off. Who should skip it? Anyone who wants a single flat nonstick surface to cook a steak or a pizza on, and anyone who wants a brush included. This product is a rack and only a rack — the packaging contains the three-layer rack, nothing more.
HERCHR takes the opposite approach: one round, ready-to-cook surface. It is a 20 cm replacement crisper plate made of food grade 304 stainless steel with a nonstick coating, designed to swap in for the original rack in most round-cavity air fryers. If your stock rack has gone missing, warped or never drained well, this is a direct substitute rather than an add-on.
The engineering here is about airflow and grease. The plate has a large number of long and round hollow holes across its surface, plus a perforated channel through the middle, and the idea is that hot air can move up through the food from below instead of only circulating over the top. That is what helps food cook more evenly and what lets excess oil drip away from what you are cooking rather than sitting under it. The result is the crispier texture people buy an air fryer for in the first place — and less fat left on the food.
Two details make it more livable than a bare metal plate. First, there are eight small square anti-slip feet attached to the grill buckles. They keep the plate from sliding around, cut down vibration, and protect the basket walls from scratches — a small thing until you have watched a loose rack bang around inside a running air fryer. Second, there is a handle, so you can lift the hot plate out of the basket without fishing for an edge. The package also includes a high-temperature silicone oil brush, which is a genuinely useful pairing: you can brush oil or sauce onto food directly, and the brush doubles as a cleaning aid for the grill.
Side-by-Side: Which Should You Choose?
• Best for dehydrating fruit, herbs or jerky → Flylin Stainless Steel Dual. Three stackable layers beat one flat surface when you are drying in batches.
• Best for draining oil under food → HERCHR Air Fryer Replacement. The perforated holes and central airflow channel are purpose-built to shed grease.
• Best for nonstick convenience → HERCHR Air Fryer Replacement. The coating releases food easily and cleans up with a wipe.
• Best for uncoated, coating-free durability → Flylin Stainless Steel Dual. 304 stainless steel with no nonstick layer to scratch or wear.
• Best for round-cavity air fryer fit → HERCHR Air Fryer Replacement. It is a 20 cm round plate meant to replace the original rack; the anti-slip feet and handle fit the same basket.
• Best for storage and draining outside the air fryer → Flylin Stainless Steel Dual. It works as a household rack for fruit and vegetables, so it stays useful between cooks.
• Best if you want a brush in the box → HERCHR Air Fryer Replacement. The silicone oil brush comes with it; Flylin's package is the rack only.
• Best for small kitchens with limited height → HERCHR Air Fryer Replacement. A flat plate adds almost no height, while the Flylin rack needs about 4.5 inches of clearance.
If I were buying for myself, I would take the HERCHR Air Fryer Replacement. It solves the problem most air fryer owners actually have — the food sitting in its own oil on a tired original rack — and it does so with airflow holes, a nonstick surface, anti-slip feet, a handle and a brush already included. It is the lower-effort upgrade. I would only switch to the Flylin Stainless Steel Dual if my priority were stacking layers for dehydrating, or if I wanted an uncoated stainless rack that doubles as a draining and storage rack. Both are sensible; they just answer different questions. Check the current price on Amazon before you commit, and measure your basket first — fit matters more than anything else here.
FAQ
It is a 20 cm round plate designed for most round-cavity air fryers, so measure your basket's inner diameter before ordering. It is meant to replace or upgrade the original rack, not to sit on top of it. If your basket is square or unusually small, this plate is probably not the right shape.
HERCHR is the easier daily clean because the nonstick coating releases food with a wipe, and the rack, brush and silicone mat are all washable — just avoid abrasive pads and metal scouring balls. Flylin's layers detach and go in the sink or dishwasher, but bare stainless steel can hold onto baked-on residue a little more stubbornly.
You could, in principle, but it is not necessary. The Flylin rack needs about 4.5 inches of clearance, so stacking it on top of a plate in a shallow basket may leave no room to close the drawer. Pick the one that matches your main cooking habit and keep the other on your wishlist.
