• Belfort Etech Silicone Liners — biggest strength: Tailor-made for the Ninja Foodi MAX Dual Zone 10-quart baskets (DZ550 / DZ401), with 0.3-inch raised silicone lines on the base that keep food off the bottom and let air circulate underneath.
• Belfort Etech Silicone Liners — biggest trade-off: They are built for one family of air fryers. If you don't own a 10-quart Ninja dual-zone, the fit simply won't be right, and silicone will never give you hard grill marks.
• KunoNana Air Fryer Grill — biggest strength: Food-grade stainless steel with a nonstick coating and a built-in handle, sized for the PowerXL Vortex Pro 8 QT, plus a kit that includes six rubber bumpers and a cleaning cloth.
• KunoNana Air Fryer Grill — biggest trade-off: It's a metal grate, so drippings still land in the basket below, and it only fits the 8 QT Vortex Pro — wrong machine, wrong pan.
• Who each pick is for: Belfort Etech for Ninja dual-zone 10-quart owners who hate scrubbing and want tender, evenly heated food; KunoNana for PowerXL Vortex Pro 8 QT owners who want seared edges and a grill-like finish.
The Belfort Etech liners are the rare accessory that was actually measured for a specific basket instead of being cut to a generic "large." Each liner measures 8.3 x 6.3 x 4.4 inches and is designed around the Ninja Foodi MAX Dual Zone 10 Quart (DZ550 / DZ401), which means you get two pieces that drop into a dual-zone setup without folding, trimming or wedging. The material is platinum-cured food-grade silicone, BPA-free and non-toxic, rated from -60°F up to 464°F. That range covers basically everything an air fryer does, from frozen fries to reheated leftovers, and it means the liner won't warp or give off odors the way cheap silicone sometimes does.
What I find genuinely smart here is the base design. The bottom has 0.3-inch raised silicone lines, and the point of those ridges is airflow. Food sits above the floor of the liner, hot air moves underneath, and moisture and oil drain away instead of pooling. Belfort Etech also states these lines let you cook at roughly the same speed as using the air fryer with no liner at all — which is the whole reason a lot of people avoid liners in the first place. At 0.1 inch thick, the walls hold their shape when you lift a full liner out, so you're not dealing with a floppy silicone bag that spills before it reaches the counter. Cleaning is the other half of the pitch: the silicone inverts, rinses, and is dishwasher safe, though hand washing is recommended if you want to keep it looking new.
KunoNana Air Fryer Grill: Who It's For
The KunoNana grill pan takes the opposite approach. Instead of shielding the basket, it replaces the cooking surface with a stainless steel grate roughly 10 x 10 inches, built specifically for the PowerXL Vortex Pro 8 QT. The steel is food-grade and FDA-compliant, BPA-free, odorless and non-toxic, and it's finished with a smooth nonstick coating so proteins release cleanly. There's a practical handle on the tray, which matters more than it sounds — lifting a hot grate out of a deep basket with tongs is how people burn knuckles and lose dinner to the floor. That handle plus the dishwasher-safe construction makes the whole routine shorter.
The design language here is all about "whirlwind" airflow. The grate has a vortex-style structure meant to push heat around the food rather than just up through it, which is the mechanism behind crisp, golden edges on steak, chicken wings, fish, fries, pizza and vegetables. Because it's metal, it heats up and transfers that heat directly to whatever is sitting on it, so you get browning and texture that a silicone surface can't produce. The trade-off is honest and worth stating plainly: a grate is open. Fat and crumbs fall through to the basket underneath, so you're still cleaning the basket — just less of it, and nothing is welded on.
The package is also more complete than most single-piece accessories. You get the grill pan, six protective rubber bumpers that keep the grate from scratching the basket and rattling around, and a nonstick cleaning cloth. KunoNana's own care notes are worth repeating: measure your basket before buying, and skip harsh brushes or metal pads, which will chew through the coating. Who should buy it? PowerXL Vortex Pro 8 QT owners who want grill-style results and don't mind a basket rinse afterward. Who should skip it? Ninja dual-zone owners — the 10-inch square won't sit right — and anyone who wants zero contact between food and the basket floor.
• Best for easy cleanup → Belfort Etech Silicone Liners. The liner is the thing that gets dirty, and it goes straight into the dishwasher.
• Best for grill marks and browning → KunoNana Air Fryer Grill. Stainless steel transfers heat directly; silicone does not.
• Best for Ninja Foodi MAX Dual Zone 10 QT (DZ550 / DZ401) → Belfort Etech Silicone Liners. The 8.3 x 6.3 x 4.4-inch shape is designed for those exact baskets.
• Best for PowerXL Vortex Pro 8 QT → KunoNana Air Fryer Grill. The 10 x 10-inch pan and handle are tailored to that model.
• Best for delicate, sticky food → Belfort Etech Silicone Liners. Non-stick silicone with a ridged base handles fish and marinated proteins without tearing.
• Best for searing steak, wings and pizza → KunoNana Air Fryer Grill. The vortex airflow structure and metal surface are aimed at crisp, golden results.
• Best temperature flexibility → Belfort Etech Silicone Liners. Rated from -60°F to 464°F, so it tolerates freezing and high heat without deforming.
• Best starter kit → KunoNana Air Fryer Grill. You get the pan, six rubber bumpers and a cleaning cloth in one box.
If I had to pick one, I'd buy the Belfort Etech Silicone Liners — but only because my priority is a clean basket and two liners that fit a dual-zone Ninja without any fiddling. In my opinion, the 0.3-inch raised base lines are the detail that makes it work: you keep airflow and even heat instead of trading performance for convenience. That said, if you own a PowerXL Vortex Pro 8 QT and you actually want browned, grill-style food, the KunoNana Air Fryer Grill is the better tool, and I'd choose it without hesitation for steak, wings or pizza. Match the accessory to your machine first — that's the decision that matters most.
what are the best air fryer accessories
It depends on your air fryer and what you cook. For Ninja Foodi MAX Dual Zone 10 QT owners, a fitted silicone liner like the Belfort Etech keeps baskets clean while its raised base lines preserve airflow. For PowerXL Vortex Pro 8 QT owners, a stainless steel grill pan like the KunoNana gives you browning and a handle for safe removal. Both are dishwasher safe, so cleanup is the common win.
Not necessarily. The Belfort Etech liners have 0.3-inch raised silicone lines on the bottom that lift food off the floor and let hot air circulate underneath, and the brand states you can cook at roughly the same rate as with no liner. You'll get even heat and less sticking, but for hard searing and grill marks, a metal grate like the KunoNana is the better choice.
Yes — this is the single biggest reason accessories get returned. The Belfort Etech liners are 8.3 x 6.3 x 4.4 inches and designed for the Ninja DZ550 / DZ401 10 Quart. The KunoNana grill pan is about 10 x 10 inches and made for the PowerXL Vortex Pro 8 QT. Measure your basket before you order.
The Belfort Etech silicone liners are dishwasher safe and can be inverted and rinsed by hand, though hand washing is recommended to keep them in shape. The KunoNana grill pan is dishwasher safe and comes with a nonstick cleaning cloth; the brand advises against harsh brushes or metal pads, which can damage the coating. The included rubber bumpers also protect your basket from scratches.
