• GWYSY Oven Liners — biggest strength: four large reusable PTFE mats (13.8" × 12") that you can trim to size, rated to 480°F, and use in air fryer ovens, microwaves and regular ovens alike. Biggest trade-off: they don't come pre-cut for one specific model, so if you want a zero-effort drop-in fit you'll be doing the trimming yourself.
• Oxyooh Air Fryer Liners — biggest strength: a 102-piece set that pairs 100 pre-cut parchment sheets for the Ninja French Door FO101 with 2 reusable PTFE mats, so you get one-and-done convenience plus a reusable option. Biggest trade-off: top heat limit is 450°F, and the whole set is built around one tray size rather than being universal.
• Who GWYSY is for: cooks with mixed appliances — an Emeril Lagasse 25 QT, a Ninja, a Cuisinart, a Breville — who want one liner they can shape to whatever tray they're using.
• Who Oxyooh is for: Ninja French Door FO101 owners who want liners that fit out of the box and don't mind having a disposable option on hand for messy meals.
GWYSY's pitch is versatility, and the numbers back it up. You get four liners in the pack, each measuring 13.8" by 12" — a genuinely large surface that covers the bottom of a big air fryer oven rather than just a small basket. They're made from PTFE over a fiberglass base, BPA-free and PFOA-free, and they're rated to 480°F (248°C). That ceiling matters if you like to push your oven hot for roasting or crisping.
The part I find most practical is the trim-to-fit design. GWYSY lists compatibility with popular air fryer ovens from Ninja, Cuisinart, Breville and Emeril Lagasse, including the Emeril 25 QT, but the real value is that you can cut them down to whatever tray or rack you actually own. One pack then covers your air fryer oven, your microwave and your regular oven — you're not buying three different products.
Who should buy it: anyone running more than one appliance, anyone who wants a reusable mat they can cook directly on as a baking surface, and anyone who'd rather buy four durable liners once than keep restocking single-use paper. Who should skip it: if you own a Ninja French Door FO101 specifically and you want liners that fit perfectly with no scissors involved, GWYSY's universal sizing is more work than you need. That's not a flaw — it's just a different design goal.
Oxyooh Air Fryer Liners: Who It's For
Oxyooh takes the opposite approach: it solves one problem extremely well instead of many problems adequately. Everything in this set is built around the Ninja French Door FO101. The parchment sheets are pre-cut to match that tray exactly — no trimming, no folding, no measuring. You drop one in and cook.
The set is 102 pieces: 100 disposable parchment sheets plus 2 reusable PTFE baking mats. The parchment is made from natural wood pulp with food-grade silicone coating on both sides, and it's rated to 450°F. Oxyooh notes it resists tearing under greasy wings and crispy fries, which is the realistic failure mode for cheap parchment. The two reusable mats are BPA-free, PFOA-free, dishwasher safe, and described as built for hundreds of uses — so the box gives you a fast option and a durable option.
There's one detail worth repeating because it's a genuine safety point, not marketing: always put food on top of the liner to weigh it down and keep it off the heating element, and don't use liners during preheating. That applies to any liner in an air fryer, and Oxyooh states it plainly.
Who should buy it: FO101 owners who value speed above all, people who cook messy proteins often and would rather toss a sheet than wash a mat, and anyone who wants both formats in one purchase. Who should skip it: if your air fryer isn't a French Door FO101, the pre-cut sheets may not match your tray, and the 450°F ceiling is lower than GWYSY's. Also skip it if you're specifically trying to eliminate disposable paper from your kitchen — 100 of the 102 pieces here are single-use.
Side-by-Side: Which Should You Choose?
• Best for exact drop-in fit → Oxyooh Air Fryer Liners. Pre-cut for the Ninja French Door FO101, no trimming required.
• Best for multiple appliances → GWYSY Oven Liners. Four 13.8" × 12" mats you can trim to air fryer ovens, microwaves and conventional ovens.
• Best for high-heat cooking → GWYSY Oven Liners. 480°F versus Oxyooh's 450°F.
• Best for a fully reusable setup → GWYSY Oven Liners. All four pieces are reusable mats, no disposables in the pack.
• Best for mixed cooking styles → Oxyooh Air Fryer Liners. Disposable sheets for quick greasy meals, PTFE mats for heavy roasting and sticky pastry.
• Best for dishwasher convenience → Oxyooh Air Fryer Liners. Its reusable mats are explicitly dishwasher safe.
• Best for one-size-fits-most flexibility → GWYSY Oven Liners. Universal sizing you adapt to your tray instead of a tray-specific cut.
If you're still weighing it up, check the current price on Amazon for each — the value math changes depending on how you'll actually use them, and this page's buttons will take you there.
If I had to pick one for myself, I'd buy GWYSY Oven Liners. I cook across an air fryer oven and a regular oven, and four large trimmable mats at a 480°F rating cover more of my kitchen than a set built for a single model. The reusable-everything design also means no restocking.
That said, if you own a Ninja French Door FO101 and you want liners that fit the second you open the box, Oxyooh is the smarter buy — the pre-cut parchment is genuinely convenient, and the two reusable mats keep it from being purely disposable. Match the product to your appliance and you'll be happy either way.
How to use reusable air fryer liners
Place the liner flat on the tray or basket, then always set your food on top of it. The food's weight keeps the liner from lifting into the heating element. Don't use liners during preheating — Oxyooh states this explicitly, and it's good practice for any brand.
How to clean reusable air fryer liners
GWYSY describes its non-stick surface as wiping clean in seconds. Oxyooh's reusable PTFE mats can be rinsed or run through the dishwasher. For either, warm soapy water and a soft sponge handle grease without damaging the non-stick coating.
Can you put liners in air fryer
Yes, both products are designed for air fryer use — GWYSY up to 480°F and Oxyooh up to 450°F. The key rules are to keep the liner weighted down with food and never leave one in during preheat.
Not identically. GWYSY's 13.8" × 12" mats are trimmable, so they adapt to most trays. Oxyooh's parchment is pre-cut for the Ninja French Door FO101, so it fits that model precisely and may not match other trays.
