• mutvle Air Fryer Liners — best for mess-free everyday cooking in a Ninja Crispi glass air fryer; pick this if you want pre-shaped, disposable liners in two sizes (90 large for the 4-QT glass container, 60 small for the 6-cup container) that need no folding or cutting.
• Goldlion Appliance Sliding Tray — best for pulling a heavy countertop air fryer or Ninja Foodi out from under a cabinet; pick this if you want a 16.1 x 11.7 inch low-profile sliding surface with a silicone non-slip pad and lever control.
• INFRAOVENS Air Fryer Liner — best for reusable, dishwasher-safe protection of a Ninja Foodi XL / Smart XL grill basket; pick this if you want a raised silicone mat plus mesh mats that lift food out of drippings and catch small pieces.
• Lancisism Air Fryer Accessories — best for stacking more food into a 4.2–5.8 QT air fryer at once; pick this if you want three stackable 304 stainless steel racks with an anti-burn clip and a foldable, space-saving design.
This is a consumables product, not a gadget — and that's exactly why I'd start here. The set is 250 pre-cut paper liners built for the Ninja Crispi glass air fryer: 90 large ones shaped for the 4-QT glass container and 60 small ones for the 6-cup container. The liners are square bowl shape, which means no tearing, folding, cutting or bending before you cook. You drop one in, add food, cook, lift it out, throw it away.
The material story matters if you cook in this thing most days. These are made from unbleached natural wood pulp with a plant-based oil treatment — no fluorescent agent, BPA-free and PFAs-free — and they're stated as 12% thicker than ordinary parchment, heat resistant up to 450°F/230°C. Thicker paper is the difference between a liner that holds up under a wet, saucy piece of chicken and one that tears as you lift it. The square bowl shape plus an oil-leak-resistant design is what keeps grease off the glass bowl in the first place, which is the whole point: fewer hand-wash sessions on a container that's awkward to scrub.
Daily use is genuinely low-effort. Because the sizes are cut for the two Crispi containers, you're not measuring anything — grab the right stack and go. The liners also work for baking, roasting, frying and even serving, so they earn their cabinet space beyond the air fryer. Packaging is a transparent hangable plastic box that's waterproof and dustproof, which sounds trivial until you've had loose parchment jammed in a drawer; here you can see how many are left at a glance.
The trade-off is honest: this is a fit-specific, disposable product. If you don't own a Ninja Crispi glass air fryer, the sizing won't do you much good. And if you'd rather not repurchase paper at all, a reusable mat is the more logical route — that's what the INFRAOVENS pick below is for. For everyone else, in my opinion this is the single easiest upgrade to make cooking in the Crispi feel less like a chore.
Here's a problem nobody warns you about before buying an air fryer: it lives on the counter, it's heavy, and it sits under a cabinet, so every use means dragging it out and shoving it back. The Goldlion sliding tray solves that one specific annoyance. It's a rectangular iron tray — 16.1 inches long by 11.7 inches deep and only 0.9 inch tall — with a lever you press down to roll the appliance back and forth. No lifting. No scraping the countertop.
The low height is the smart part of the design. At under an inch, it doesn't eat the clearance between your counter and upper cabinets, so taller appliances still slide out without knocking into anything. The surface is sized to hold most countertop appliances: the Ninja Foodi pressure cooker, Instant Pot, COSORI air fryer, Keurig K-Cafe and Vitamix blender are all called out as fits. Note the exclusion — Goldlion states it's not for the Ninja Grill, so if a grill is what you're moving, this isn't the one.
The non-slip pad is silicone rather than EVA foam. In practice that means two things: it holds the appliance steady while you're sliding it, and it wipes clean instead of degrading into a crumbly mess over time. The black modern finish is discreet enough that it reads as part of the counter rather than another appliance.
Who is this for? Anyone with limited counter depth who keeps a heavy air fryer or multi-cooker parked under a cabinet. The trade-off: it's a single-purpose accessory that takes up a fixed footprint, and you do need to confirm your appliance's base fits within that 16.1 x 11.7 inch surface before buying — and that it isn't a Ninja Grill. If your air fryer already has open space around it, you don't need this at all.
This one is for the Ninja Foodi XL / Smart XL indoor grill crowd — the FG551 family and the long list of compatible model numbers INFRAOVENS publishes (BG500A, DG551, FG550, FG551 and many variants). It's a reusable silicone mat measuring 11 x 7.6 inches, plus mesh mats, and it replaces parchment paper entirely.
The design does two jobs. First, protection: the raised silicone mat sits under your food so residue, grease and fat never reach the basket or rack, which keeps the machine cleaner and, in my opinion, meaningfully extends how long the basket stays looking new. Second, better cooking: because food is elevated, oils and fat drip away instead of pooling around it, and the airflow underneath helps crisp the underside more evenly. Anyone who has pulled half-soggy fries out of an air fryer knows why that matters.
The mesh mats handle a different problem — small foods. Wings, nuggets, vegetable pieces and anything that would otherwise drop through the basket openings stay put, and the mats also make it easier to cook looser, more liquid-leaning foods that would normally make a mess. Everything is food safe, reusable and dishwasher safe, so cleanup is a matter of loading the dishwasher rather than scrubbing.
Where it falls short: it's built around a specific set of Ninja Foodi grill and XL models, so it's not a universal mat — check your model against the list before ordering. And silicone mats, while reusable, still need to be washed between heavy uses, which is slightly more work than tossing paper. If you want zero washing and own a Crispi, the mutvle liners are the better fit. If you want to stop buying parchment, this is the pick.
The Lancisism set is the one that actually changes how much food you can cook at once. It's three stackable racks made of food-grade 304 stainless steel, each roughly 7.9 x 7.9 x 1.6 inches, sized for air fryers in the 4.2 QT to 5.8 QT range — Ninja, Ninja Foodi, GoWise and Philips are all named as compatible. The three-tier stacking is the headline: instead of one layer of food, you get three.
That's a real difference for anyone cooking for more than one person. Dehydrating fruit or herbs, baking chips and nuts, roasting vegetables, or doing steak and sides at the same time all become single-batch jobs. The racks are rust, corrosion and high-temperature resistant, and the edges are sanded smooth with no burrs, so you're not going to catch a finger pulling them out. A non-stick surface keeps residue from welding itself on.
Two design details earn their keep. There's an anti-burn clip, about 6.7 inches long, for lifting the hot rack out safely — small thing, big difference when you're reaching into a 400-degree basket. And the racks are foldable and detachable, so when they're not in use they collapse down instead of monopolizing a cabinet shelf. Cleaning is a wipe with a damp cloth or a trip through the dishwasher. The set includes three mesh racks and an oil brush.
The trade-off is capacity math. Stacked racks reduce the vertical space per layer, so thick cuts of meat won't fit three-high — this shines with smaller, flatter items. It's also sized for 4.2–5.8 QT machines, which means it won't suit a compact 2 QT air fryer or a large dual-basket model. If you mostly cook one portion at a time, you don't need it. If you regularly wish your air fryer held more, I'd recommend it.
We compared the published specifications and features of each product — materials, dimensions, stated compatibility, construction details and how each one solves a specific problem in real kitchen use. The ranking reflects our independent editorial opinion about which product suits which shopper. No brand paid for placement, and no product was included because of anything other than what its data sheet says it does.
Not strictly. Liners mainly save cleanup time and keep grease off the basket. Disposable paper liners like the mutvle set suit the Ninja Crispi glass containers, while a reusable silicone mat like the INFRAOVENS one is the better choice if you'd rather not repurchase paper.
The Goldlion tray is only 0.9 inch tall, which is designed to preserve clearance under upper cabinets. Measure the space between your counter and cabinet, and confirm your appliance's base fits within the 16.1 x 11.7 inch surface. Goldlion notes it is not intended for the Ninja Grill.
If you regularly cook for two or more people, yes — three tiers let you cook far more in one go and are useful for dehydrating and roasting. If you usually cook a single portion, the extra layers add handling without adding much benefit.
The mutvle liners are stated as heat resistant up to 450°F/230°C, the INFRAOVENS mats are described as heat resistant and dishwasher safe, and the Lancisism racks are 304 stainless steel rated for high-temperature use. Always follow your air fryer's own maximum temperature guidance.
