If you want a drop-in crisper plate that turns your 5.5-quart Ninja AF150AMZ into a better grill and crisper, choose GSZN 5.5QT; if you need a multi-layer stainless rack system for a Ninja Combi 14-in-1, choose INFRAOVENS Air Fryer Rack. These two accessories look similar in a listing thumbnail, but they solve completely different problems, and buying the wrong one means it either won't fit or won't do what you wanted.
• GSZN 5.5QT — biggest strength: A round, double-layer nonstick carbon steel crisper plate sized specifically for the 5.5QT Ninja AF150AMZ Air Fryer XL, with a handle for lifting it out and dishwasher-safe cleanup.
• GSZN 5.5QT — biggest trade-off: It only fits that one air fryer family. If you own a different brand or a larger model, this plate is not for you.
• INFRAOVENS Air Fryer Rack — biggest strength: A stainless steel rack plus reusable liners and a mesh mat that let you stack layers inside a Ninja Combi SFP701, so you cook more food at once and keep the trays clean.
• INFRAOVENS Air Fryer Rack — biggest trade-off: It's built for the Ninja Combi 14-in-1 multicooker, not a standard basket-style air fryer, so it's useless to anyone without that appliance.
• Who each pick is for: GSZN for owners of the 5.5QT Ninja AF150AMZ who want crispier grilling and easier release; INFRAOVENS for Ninja Combi SFP701 owners who want layered cooking and less scrubbing.
The GSZN 5.5QT is a single-purpose accessory done deliberately. It's a round crisper plate made from food-grade carbon steel with a double-layer nonstick coating, and it's shaped to sit inside the 5.5-quart Ninja AF150AMZ Air Fryer XL. The idea is simple: instead of cooking directly on the air fryer's basket bottom, you set food on this plate, which has a handle so you can lift the whole thing out without tongs gymnastics. It measures about 8 x 8 x 0.5 inches and weighs next to nothing, so it doesn't eat into your cooking capacity in any meaningful way.
What it does best is the job most air fryer owners actually want: better browning and crisping on the underside of food, plus a nonstick surface that releases food cleanly and goes in the dishwasher. The double-layer coating is described as high-temperature resistant and resistant to flaking, which matters because a cheap single-coat tray tends to peel after a few months of high-heat use. GSZN also includes three silicone rubber bumpers and a nonstick cleaning cloth, which tells you the company expects you to baby the coating rather than attack it with steel wool.
Buy it if you own the 5.5QT Ninja AF150AMZ and want a dedicated crisper plate for things like chicken thighs, vegetables, bacon or reheated leftovers. Skip it if you own any other air fryer, a different Ninja size, or a multicooker — the fit is specific, and the listing itself notes you may need to adjust the tension of the tray's feet to seat it properly. Also skip it if you mainly want to cook in multiple stacked layers; this is one flat plate, not a rack system.
The INFRAOVENS Air Fryer Rack is a different animal entirely. It's a stainless steel rack designed for the Ninja Combi SFP701 14-in-1 multicooker, and the whole point is vertical space. You set the rack inside the Combi, elevate food on it so hot air circulates underneath, and then use the included reusable liners and mesh mat to protect the trays and keep small pieces from dropping through the gaps. The set includes a rack, a reusable liner and a reusable mesh, with the liners sized for both the large and smaller Combi trays.
The material story here is the selling point. Stainless steel won't rust, peel or flake the way coated racks eventually can, so nothing is shedding into your food over time. The liners are PFOA-free fiberglass, dishwasher safe, and rated to 400°F, and INFRAOVENS lists the rack as suitable for cooking, baking, broiling, reheating, dehydrating, steaming and roasting. That's a genuinely broad range, and it lines up with the Combi's whole pitch as a do-everything appliance. The mesh mat is the detail I like most: it turns the rack into a usable surface for small items like fries or nuggets that would otherwise fall straight through.
Buy it if you own a Ninja Combi SFP701 and find yourself limited by single-layer cooking, or you're tired of scrubbing baked-on residue off your Combi trays. Skip it if you have a standard basket air fryer — this won't fit, and the layered-rack concept only makes sense inside a Combi-style multicooker. Note that INFRAOVENS is an independent accessory maker and states it isn't affiliated with or endorsed by the Ninja brand; the rack is simply built to fit that appliance.
Side-by-Side: Which Should You Choose?
• Best for the Ninja Combi SFP701 14-in-1 → INFRAOVENS Air Fryer Rack. Nothing about the GSZN plate helps you here.
• Best for crisping and grilling in a single layer → GSZN 5.5QT. A flat nonstick plate gives you direct, even contact and easy release.
• Best for cooking more food at once → INFRAOVENS Air Fryer Rack. Stacking layers is the rack's whole purpose, and the mesh mat expands what you can put on it.
• Best for long-term durability against heat and moisture → INFRAOVENS Air Fryer Rack. Bare stainless steel can't peel or flake; a nonstick coating always eventually can.
• Best for easy cleanup → a tie, with different mechanics. GSZN is dishwasher safe with a nonstick surface; INFRAOVENS is dishwasher safe and uses liners so the trays barely get dirty.
• Best for small, loose food like fries or nuggets → INFRAOVENS Air Fryer Rack. The mesh mat exists precisely to stop small pieces falling through.
• Best for a simple, low-fuss upgrade → GSZN 5.5QT. One plate, one job, no assembly or layering to think about.
If I owned a 5.5QT Ninja AF150AMZ, I'd buy the GSZN 5.5QT. In my opinion it's the cleaner solution for the most common air fryer frustration — food that doesn't crisp underneath and sticks to the basket — and the handle plus dishwasher-safe nonstick coating make it genuinely convenient day to day. I'd only reach for the INFRAOVENS Air Fryer Rack if I had a Ninja Combi SFP701 and wanted to cook in layers while keeping my trays clean. These aren't competitors so much as answers to two different questions. Match the accessory to the appliance you actually own, and you'll be happy either way.
FAQ
No. GSZN states it's made for the 5.5-quart Ninja AF150AMZ Air Fryer XL. If you own a different model or size, the plate likely won't seat correctly, so check your model number before buying.
Both are dishwasher safe, so it's close. GSZN relies on its nonstick coating, which you should avoid scrubbing with abrasives. INFRAOVENS uses reusable liners and a mesh mat, so residue often never reaches the rack itself. For baked-on messes, the liner approach wins in my view.
I don't quote prices here — check the current price on Amazon using the button on this page. Value really comes down to fit: the GSZN plate is the better buy if you own the AF150AMZ, and the INFRAOVENS set is the better buy if you own a Ninja Combi. Buying the wrong one is the only genuinely bad deal.
