Measure the interior dimensions of your air fryer basket and compare them to the plate dimensions listed for each product. Most Ninja models need an 8.2 × 8.2 inch plate, while Cosori 5‑qt units use an 8.1 × 8.1 inch size. Instant Pot Vortex and Gourmia models have slightly larger plates around 9 × 9 inches. Choosing the exact match prevents gaps that reduce airflow and uneven cooking.

Stainless‑steel plates, like those on the Instant Pot Vortex and Cosori models, are highly durable, rust‑free, and often dishwasher‑safe, but they rely on a Teflon or enamel non‑stick coating for easy release. Ceramic‑coated plates, such as the Ninja replacement, provide a natural non‑stick surface without PTFE, which some users prefer for health reasons. Both materials perform well, so the choice depends on your preference for durability versus a PTFE‑free surface.

A well‑designed handle lets you lift the plate out of the hot basket without burning your fingers, which is especially useful when cooking heavy items like steak. All listed plates feature a central handle, but the Ninja and GWY models highlight a double‑layer enamel coating for extra grip. This small feature can improve safety and make cleaning easier.

Rubber bumpers protect the interior walls of your air fryer from scratches caused by the metal plate, extending the life of both the appliance and the accessory. Cosori, Chefman, and GWY kits include four bumpers, while the Ninja and Instant Pot options may omit them. If your fryer has a delicate coating, choosing a plate with bumpers adds extra value.

The GWY 8‑inch Ninja plate provides a versatile size, a sturdy non‑stick enamel coating, and includes a cleaning cloth plus multiple bumpers, giving a comprehensive package at a modest price. The Instant Pot Vortex plate also offers a solid stainless‑steel build with an enamel coating and is dishwasher‑safe, but it lacks extra accessories. Overall, GWY delivers the most features for the cost.

Yes, most of the plates listed have perforated or airflow‑optimized designs that allow hot air to circulate, which is ideal for dehydration. The Instant Pot Vortex and Gourmia models explicitly mention dehydrating as a use case. Just be sure to spread food in a single layer and use the lowest temperature setting for best results.

Avoid abrasive sponges, steel wool, or metal scrubbers, as they can damage the coating and reduce its lifespan. Wash the plates in the dishwasher or by hand with a soft sponge and mild detergent, and dry them thoroughly before storing. Periodic seasoning with a thin layer of oil can also help preserve the non‑stick surface.

A larger plate, such as the 8.97 × 8.97 inch Gourmia grill pan, maximizes the cooking area and lets you fit more food in a single batch, reducing overall cooking time. However, ensure your specific Gourmia model matches the dimensions; some 7‑qt units have slightly smaller baskets. If you frequently cook for a family or like to batch‑cook, the larger plate offers clear convenience.
