If you want one small round rack that fits a wide range of air fryers, stockpots and pressure cookers, choose WHTCHSU 1; if you need a dedicated replacement crisper rack built for specific Ninja Crispi glass-container models, choose Itsall Stainless Steel Replace.
• WHTCHSU 1 — biggest trade-off: it is a generic size, so it only works if the diameter and height actually suit your appliance; nothing about it is model-specific.
• Itsall Stainless Steel Replace — biggest strength: it is a purpose-built replacement rack for a defined list of Ninja Crispi models, in 2.5Qt and 4Qt glass containers, rated for heat up to 500°F.
• Itsall Stainless Steel Replace — biggest trade-off: it is narrow by design. It does not fit 5-cup or 6-cup containers, it must stay out of the microwave, and it is useless outside that Ninja ecosystem.
• Who each pick is for: WHTCHSU 1 for the cook who wants one flexible round rack to layer, steam, cool or roast across several vessels; Itsall for the Ninja Crispi owner who specifically needs to replace or add a crisper rack for their glass container.
WHTCHSU 1 is a single round rack, 5.9 inches across, made of pure stainless steel with a mirror finish and seamless welded wire. Each rack sits about 1 inch high off the base, which is the whole point: that gap lets hot air move under and around the food instead of trapping it against a flat surface. In an air fryer basket, a stockpot or a pressure cooker, that translates into more even browning and faster cooking on repeat batches. The close parallel wire spacing also keeps smaller pieces from slipping through, and the smooth, rounded edge means you can lift it out without hunting for a towel.
The honest trade-off is that it is a generalist. It is not shaped or sized for any one machine. If your air fryer basket is significantly wider or narrower than the rack, or if you need the rack to key into a specific container rim, this is not that product. It simply drops in and sits there.
So who should buy it? I recommend WHTCHSU 1 for anyone who wants a small, rust-resistant, dishwasher-safe rack they can move between appliances — layering food in an air fryer, lifting a chicken off the bottom of a pot, cooling cookies on a round cake pan, or draining oil and water off fried food. The thick wire and sturdy feet mean it will hold heavier items without bowing, and the stainless steel construction is meant to survive years of oven heat and washing. It is also a sensible choice if you already own several vessels of similar diameter and want one insert that works in all of them.
Itsall Stainless Steel Replace: Who It's For
Itsall Stainless Steel Replace is a different kind of product entirely. It is a replacement crisper rack made from solid SUS304 stainless steel with no coating, so there is nothing to peel or degrade when it is exposed to high heat. The seamless welded wire is designed to hold its shape up to 500°F, and the elevated structure is there to keep air moving around the food for more consistent results.
The defining feature is compatibility. This rack is built for Ninja Crispi air fryer models FN090, FN091, FN100, FN101 and FN103, and it is designed for 2.5Qt and 4Qt glass containers only. It is explicitly not compatible with 5-cup or 6-cup containers, and it must not go in a microwave. That is a narrow lane, but inside that lane it is the correct part: you place it directly into the compatible glass container, no tools needed, and let it cool before removing it after cooking.
Buy it if you own one of those listed Ninja Crispi models and you need to replace a lost or worn crisper rack, or you want a spare so you can cook back-to-back without waiting on a wash. The rounded, sharp-edge-free design is comfortable to handle, and it is dishwasher safe and stands up to metal utensils, which matters for daily use.
Skip it if you do not own a compatible model, if your container is 5-cup or 6-cup, or if you want a rack that can also be used in the microwave. This is a precise-fit accessory, not a universal one.
Side-by-Side: Which Should You Choose?
• Best for broad appliance compatibility → WHTCHSU 1. One 5.9-inch round rack that fits air fryers, stockpots, pressure cookers and round cake pans.
• Best for lifting food for airflow → WHTCHSU 1. Roughly 1 inch of elevation on sturdy feet, with close wire spacing so food does not fall through.
• Best for high-heat tolerance → Itsall Stainless Steel Replace. Seamless welded wire rated to hold shape up to 500°F.
• Best for non-stick-free, coating-free cooking → Itsall Stainless Steel Replace. Solid SUS304 stainless steel with no coating at all.
• Best for cooling, steaming and draining → WHTCHSU 1. Mirror finish and smooth edges make it easy to release food and rinse clean.
• Best for dishwasher convenience on both counts → either. Both are dishwasher safe; WHTCHSU 1 also washes easily by hand.
• Best for microwave use → neither. Itsall explicitly rules out microwave use, and the WHTCHSU 1 is specified for oven, air fryer and stovetop-style vessels.
In my opinion, the right answer comes down to what you already own. If you have a Ninja Crispi in one of the listed models and a 2.5Qt or 4Qt glass container, I would buy Itsall Stainless Steel Replace — it is the part that actually belongs in that machine, and the 500°F rating and coating-free SUS304 build are exactly what a crisper rack should offer. If you do not have that specific setup, I would buy WHTCHSU 1 instead, because a 5.9-inch round stainless steel rack at about 1 inch of elevation is far more useful across an air fryer, a stockpot or a pressure cooker. For most people reading this, WHTCHSU 1 is the safer, more versatile pick — but if the Itsall fits your model, it fits it perfectly.
how to use air fryer rack
Set the rack in the bottom of your air fryer basket or compatible container so the food sits above the base, then cook as normal. The WHTCHSU 1 lifts food about 1 inch to let air circulate underneath; the Itsall rack is placed directly into a compatible Ninja Crispi glass container, no tools needed. Let either rack cool before you lift it out.
how to clean air fryer rack
Both racks are dishwasher safe, and both are stainless steel, so they resist rust and everyday wear. WHTCHSU 1 has a mirror finish and smooth edges that release food easily for hand washing; Itsall is rounded and sharp-edge-free and stands up to metal utensils. For either one, a warm soapy soak handles stuck-on grease fast.
how to air fry rack of lamb
A rack of lamb is a large piece of meat, so the rack insert matters mostly for airflow and drainage. Use a rack that elevates the meat so fat drips away and heat reaches all sides — WHTCHSU 1's 1-inch elevation and sturdy feet are built for holding heavier food. If you are cooking in a Ninja Crispi, use the Itsall rack in a compatible 2.5Qt or 4Qt glass container instead.
how to air fry rack of ribs
Ribs need airflow on all sides and a rack that will not buckle under weight. WHTCHSU 1 uses thick stainless steel wire with seamless welding and sturdy feet intended to hold heavier food without warping. Keep the ribs elevated so hot air moves underneath, and check that your rack's diameter actually fits your basket before you commit to it.
