How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a constant supply of single-use liners that fit Ninja's rectangular Smart XL grill baskets and make cleanup a ten-second job, choose POPQEEN Air Fryer Liners; if you need one reusable glass liner you rinse or dishwash and use again for years, choose SVNWZGM Air Fryer Accessories.
• POPQEEN Air Fryer Liners — biggest strength: 120 pre-cut rectangular parchment sheets sized for the Ninja FG551 Foodi Smart XL 6-in-1 Indoor Grill, so you never trim or fold anything.
• POPQEEN Air Fryer Liners — biggest trade-off: every cook means a fresh sheet, and it's paper — it does nothing to change how your food browns or crisps.
• SVNWZGM Air Fryer Accessories — biggest strength: a BPA-free glass liner with silicone handles that stays rigid, goes in the dishwasher, and replaces disposable papers over and over.
• SVNWZGM Air Fryer Accessories — biggest trade-off: it's one rigid piece with a specific fit footprint, so you wash it between uses and it takes up real cabinet space.
• Who each pick is for: POPQEEN for the Smart XL / rectangular-basket owner who hates scrubbing and wants zero thinking; SVNWZGM for the dual-basket or square-basket owner who wants a buy-once, reuse-forever liner.
This is a consumables product, and it's honest about that. You get 120 sheets of food-grade parchment cut to 11.6 inches in a rectangular shape — a size chosen specifically for the Ninja FG551 Foodi Smart XL 6-in-1 Indoor Grill. POPQEEN also lists compatibility with the Ninja IG601 and IG651, and says the rectangle fits grill-and-air-fryer combos that use a rectangular basket. That last point matters more than it sounds: most parchment liners on the market are round, and a round sheet in a rectangular grill basket leaves the corners exposed, which is exactly where grease pools.
The material is food-grade parchment that's oilproof, waterproof, non-stick, and heat resistant to 428°F. Because it's paper, it's also microwave-safe and works in ovens, steamers, and regular cookware — the sheets aren't locked to the air fryer. The stated uses are the usual suspects: pizza, sausages, meatloaf, plus anything you'd line a baking tray with. The pack is light (about 0.47 kg total), which is genuinely useful if you're hauling it to a campsite or an outdoor barbecue.
So who should buy it? The person whose real complaint isn't about cooking — it's about the twenty minutes of soaking and scraping afterward. A liner that isolates food residue means the basket comes out looking the way it went in, and you avoid the repeated washing that wears down non-stick coatings over time. If you own a Smart XL or a rectangular-basket combo and you'd rather grab a sheet than scrub a grate, this is the low-effort answer.
Who should skip it? Anyone who dislikes the idea of a running consumable. If you cook daily, 120 sheets is a supply you'll work through, and you'll be reordering. And if you're chasing crispier results, understand what parchment does: it protects the basket, it doesn't improve browning. It's a cleanup tool, not a cooking upgrade.
SVNWZGM takes the opposite approach: one object, used indefinitely. The liner is high-strength, BPA-free glass with heat-resistant silicone handles. The handles are the detail I keep coming back to — a rigid glass tray full of hot grease is awkward to lift, and soft silicone grips solve the one genuinely annoying part of reusable liners. The glass itself stays flat and won't warp, which is the failure mode of thin silicone mats that curl at the edges and let drippings run underneath.
Heat resistance is rated to 428°F — the same ceiling as the parchment. But the more interesting claim is about airflow. Solid silicone mats are known to block the circulating air that makes an air fryer an air fryer; SVNWZGM says this glass liner is designed not to, so food cooks faster and more uniformly, and the fit doesn't obstruct the heating elements or the fan. Take the "perfectly crispy" language as marketing, but the design logic is sound: a rigid liner with a lower profile interferes less than a flat mat pressed across the basket floor.
Fit is the catch, and it's a real one. The liner is aimed at most 9-quart Ninja dual-basket models, including the DZ series (DZ401, DZ550), plus SL401 and SL451 10-quart units, and 4-quart square air fryers. It also works in ovens and microwaves. Note the wording: most 9-quart dual-basket models and various popular air fryers. That's a family of fits, not a universal one. Measure your basket before you commit.
Cleaning is the payoff. It's dishwasher safe, and grease and burnt-on bits rinse off the smooth glass — no scrubbing, no stains, no lingering odors. It's also non-stick and odor-free, and the whole pitch is replacing hundreds of parchment sheets and foil with one durable piece. The physical trade-off is weight and bulk: 1.61 pounds and a package footprint around 9 x 7 x 3 inches. This thing lives in a cabinet.
Buy it if you own a dual-basket Ninja or a square-basket air fryer and you want to stop buying liners. Skip it if your basket is rectangular like the Smart XL's — the geometry simply isn't aimed at you.
• Best for a Ninja FG551 Smart XL 6-in-1 Indoor Grill → POPQEEN Air Fryer Liners. The 11.6-inch rectangular cut is built for that basket.
• Best for a Ninja DZ401, DZ550, SL401, or SL451 dual-basket / 10-quart unit → SVNWZGM Air Fryer Accessories. That's the fit it was designed around.
• Best for zero cleanup effort → POPQEEN Air Fryer Liners. Cook, eat, toss the sheet. Nothing to wash.
• Best for long-term waste and cost → SVNWZGM Air Fryer Accessories. One glass liner instead of a steady stream of paper.
• Best for cooking performance → SVNWZGM Air Fryer Accessories. Airflow-friendly design and even heat distribution versus a paper layer that only protects.
• Best for travel, camping, and cookouts → POPQEEN Air Fryer Liners. Lightweight, portable, and usable beyond the air fryer.
• Best for safe handling of hot greasy food → SVNWZGM Air Fryer Accessories. Rigid glass plus silicone handles beat peeling a hot paper sheet off a tray.
• Best for ovens, microwaves, and steamers as well → either one. Both are rated to 428°F and both are microwave safe; POPQEEN adds steamer use.
In my opinion, the deciding question is whether you want a liner you throw away or a liner you keep. For a Ninja Smart XL or any rectangular-basket grill combo, I'd buy POPQEEN Air Fryer Liners — the sizing is the whole product, and 120 sheets means you won't think about cleanup for a long while. For a dual-basket or square-basket air fryer, I'd buy SVNWZGM Air Fryer Accessories; the glass, the silicone handles, and the dishwasher-safe surface make it the better object, and reusable beats disposable over a few months of cooking. Match the liner to your basket shape and you'll be happy either way.
Not really. POPQEEN is cut for rectangular baskets like the Ninja FG551 Smart XL and IG601/IG651. SVNWZGM targets most 9-quart Ninja dual-basket models (DZ series), the SL401 and SL451 10-quart units, and 4-quart square air fryers. Check your basket shape first.
It depends on how you count. POPQEEN gives you 120 single-use sheets; SVNWZGM is one reusable liner meant to replace hundreds of papers and foils. If you cook often, the reusable glass is the cheaper path over time. For current pricing, use the price button on this page.
POPQEEN's parchment protects the basket but doesn't change browning either way. SVNWZGM claims its glass liner distributes heat evenly and doesn't block airflow the way solid silicone mats do, which should help food cook more uniformly.
SVNWZGM's glass liner is dishwasher safe and also rinses clean by hand. POPQEEN's parchment sheets are disposable and microwave safe — you use them once and discard them, so there's nothing to wash.
