These two products are often compared because both are marketed as Ninja air fryer accessories, but they solve completely different problems. One is a piece of hardware you keep and wash. The other is a consumable you use once and toss. Picking wrong means either buying something that won't fit your machine or buying a stack of liners you'll never use. Here's how I'd break it down.
• GWBSXM Air Fryer Rack — biggest strength: A three-piece stainless steel set (rack, tray, basket) with a mesh design for 360° heat circulation, meaning no flipping mid-cook.
• GWBSXM Air Fryer Rack — biggest trade-off: It's built to a fixed 13.4" × 13.4" footprint for the Ninja Foodi 8-in-1 SP100/SP101 countertop oven, so it will not drop into a small basket-style air fryer.
• mutvle Air Fryer Liners — biggest strength: 250 pre-cut square bowl-shaped liners (90 large, 60 small in the stated split) that need no tearing, folding, cutting or bending, and catch oil so the machine stays clean.
• mutvle Air Fryer Liners — biggest trade-off: They're disposable and sized around the Ninja Crispi glass 4-QT and 6-cup containers, so they're a poor fit for a large countertop oven.
• Who GWBSXM is for: Anyone with a Ninja Foodi SP100/SP101 who wants reusable hardware and healthier cooking with less oil.
• Who mutvle is for: Anyone with a Ninja Crispi glass air fryer who hates scrubbing and wants to lift out the mess and throw it away.
This is hardware, and it's designed like it. You get three pieces — a grill rack, a grill tray and a crisper basket — all in food-grade stainless steel that the brand states meets FDA standards, contains no BPA, and is non-toxic and tasteless. The rack measures 13.4" × 13.4" with a stated 0.6" thickness, the tray is 13" × 13", and the basket is 13.3" × 13.5". That's a big, square footprint. It's meant to sit inside the Ninja Foodi 8-in-1 SP100/SP101 countertop oven, not a compact pod-style fryer.
What it does best is airflow. The mesh design lets heat move around the food from every direction, so you're not standing there flipping wings or fries halfway through. The brand's pitch is that you just set temperature and time and walk away. In practice, that's the real value: layered cooking. You can put protein on one level and vegetables on another and let the oven do the work.
Who should skip it? If your air fryer is a small basket model, this won't fit — full stop. The brand itself tells you to measure the inside diameter of your appliance before buying. And if you want zero washing up, this is the wrong product; it's reusable by design.
mutvle Air Fryer Liners: Who It's For
This is the opposite philosophy: nothing to clean, ever. You get 250 disposable liners made from unbleached natural wood pulp with a plant-based oil treatment. No fluorescent agent, BPA-free and PFA-free, and the brand says they're 12% thicker than ordinary parchment for sturdiness. Heat resistance is listed at up to 450°F / 230°C in the main specs, with the description mentioning 428°F — either way, comfortably above normal air frying temperatures.
The shape is the clever part. They're pre-formed into a square bowl, so there's no tearing, folding, cutting or bending. You drop one in, cook, lift it out, throw it away. The no-oil-leak design keeps the machine itself clean, which is the entire point. The paper size is 5.5" × 7.5", and the packaging is a transparent, hangable plastic box that's waterproof and dustproof, so you can see how many you have left.
Fit is specific here: these are custom-designed for the Ninja Crispi glass air fryer, with the stated split of 90 large liners for the 4-QT glass container and 60 small for the 6-cup container. That's a narrower compatibility window than the GWBSXM rack, and it's the main thing to check before buying.
Who should buy it? Crispi owners who cook greasy or sticky things regularly and are tired of soaking and scrubbing. They also work for baking, roasting, frying or serving, and they're light and flat enough to pack for camping or a BBQ. Who should skip it? Anyone without a Crispi, and anyone trying to reduce single-use waste. One practical note the brand gives: press the paper down with food and don't underfill it, or hot air can blow the liner around.
• Best for multi-level cooking → GWBSXM Air Fryer Rack. The rack, tray and basket combination lets you cook more at once in the SP100/SP101.
• Best for zero cleanup → mutvle Air Fryer Liners. Lift out, throw away, done.
• Best for Ninja Foodi 8-in-1 SP100/SP101 owners → GWBSXM. The 13.4" × 13.4" rack is sized for that oven.
• Best for Ninja Crispi glass air fryer owners → mutvle. The liners are custom-cut for the 4-QT glass and 6-cup containers.
• Best for healthier cooking with less oil → GWBSXM. The mesh basket is designed to let you cook crispy food without excess grease.
• Best for low-effort, high-volume convenience → mutvle. 250 liners in a resealable box means you're set for a long stretch of cooking.
• Best for durability and reusability → GWBSXM. Stainless steel, dishwasher-safe, and described as not easy to deform.
• Best for travel and outdoor cooking → mutvle. Flat, light, portable liners for camping and BBQs.
• Best if you're unsure about fit → measure first. GWBSXM needs a large square oven cavity; mutvle needs a Crispi glass container.
In my opinion, the right answer depends entirely on which Ninja you own, and I'd rather you get that right than chase either option blindly. If you have the Ninja Foodi 8-in-1 SP100/SP101, I'd buy the GWBSXM Air Fryer Rack — it's reusable, dishwasher-safe, and it genuinely expands what the oven can do. If you have the Ninja Crispi glass air fryer, I'd buy the mutvle Air Fryer Liners, because nothing beats lifting out the mess and binning it. Neither is a universal upgrade. Match it to your machine and you'll be happy.
No. The GWBSXM rack is sized at 13.4" × 13.4" for the Ninja Foodi SP100/SP101 countertop oven. The mutvle liners are cut at 5.5" × 7.5" for the Ninja Crispi glass 4-QT and 6-cup containers. Check your model before ordering.
They're different categories, so compare them by usage. The rack is a one-time reusable purchase you wash and keep; the liners are a 250-piece consumable you replace. For current pricing on both, use the check-price button on this page.
The specs list heat resistance up to 450°F / 230°C, which covers typical air frying and baking. The brand also notes you should press the liner down with food so hot air doesn't lift it.
Yes. It's listed as dishwasher-safe and described as firm and not easily deformed. Just avoid rough abrasive cloths or metal scouring balls, which the brand specifically warns against.
