If you want a high-count pack of perforated parchment liners sized for square and round air fryer baskets, choose DNSSY Air Fryer Parchment; if you need disposable liners that keep a slow cooker pot clean after long, saucy braises, choose Syntus 30.
• DNSSY Air Fryer Parchment — biggest strength: 200 pre-cut 8.5-inch square perforated liners made from unbleached wood pulp with a food-grade silicone coating, heat resistant to 450°F.
• DNSSY Air Fryer Parchment — biggest trade-off: You have to preheat the air fryer first and then set the paper down with food on top of it, and it is cut for air fryer baskets and steamers, not for a slow cooker.
• Syntus 30 — biggest strength: 30 BPA-free nylon-blend slow cooker liners at 10.5" x 17.5" that fit 1–3 quart round, oval and rectangular pots and hold up to 400°F for long cooks.
• Syntus 30 — biggest trade-off: Only 30 liners per pack, and they are built for a slow cooker insert — they have no place in an air fryer basket.
• Who each pick is for: DNSSY for anyone cooking in an air fryer, oven, or steamer basket who wants non-stick release and less scrubbing; Syntus 30 for slow cooker owners who want to lift out a bag instead of soaking a heavy ceramic pot.
DNSSY Air Fryer Parchment is a box of 200 pre-cut liners, each 8.5 inches square, made from 100% unbleached food-grade wood pulp with a food-grade silicone coating. The perforated design is the detail that matters most. Holes let the hot air circulate up through the paper instead of trapping it under a solid sheet, which is the usual reason food comes out overcooked on the bottom and pale on top. The coating handles the non-stick job, so bread, bacon, chicken, chips, beef, turkey, buns and dumplings lift away cleanly, and the manufacturer states the liner will not dye or tint the food.
Sizing is where you need to check your own gear before buying. The 8.5-inch square is designed for square air fryers or cake pans in the 8.5 to 9.5 inch range. The same liner also fits round or oval air fryer baskets and steamer baskets measured by diagonal length from roughly 10.3 to 11.2 inches. So measure across the basket, not just the width of the opening, and you will know quickly whether this is your size. Heat resistance runs to 450°F (232°C), which covers essentially everything a home air fryer does.
The cleaning angle is the whole point. Because the liners are waterproof and greaseproof, drips and residue stay on the paper rather than baking onto the basket, so you are not scrubbing the drawer after every batch of wings. In my opinion, this is the pick for anyone who uses an air fryer several times a week and is tired of the wash-up, or who steams buns and dumplings and wants a clean release without oiling a bamboo basket. Skip it if you do not own an air fryer, oven tray, or steamer of a matching size, or if you dislike the extra step of preheating first and then laying the paper down with food already on it.
Syntus 30 is a different tool entirely: 30 disposable slow cooker liners, each 10.5 x 17.5 inches, made from a thickened BPA-free nylon blend. They are sized for 1 to 3 quart slow cookers in round, oval and rectangular shapes, and the clear material lets you see what you are doing as you settle the bag into the pot. Heat resistance is rated to 400°F, and the description notes the liner holds up even after cooking on high for more than eight hours — the kind of long, wet cook where a thin liner would normally fail.
The construction is the selling point. High-tenacity nylon with reinforced edges is designed to resist tearing and leaking, and the manufacturer specifically calls out that the material resists punctures from bones, so bone-in meats and hearty stews are fair game. BPA-free material is stated for food safety, and the liner is described as locking in flavor and nutrients without changing taste or texture. Cleanup is the payoff: place the liner, add ingredients, cook, then lift the bag out and throw it away. No soaking, no scrubbing, and the liner also shields the pot surface from scratches, which matters on a ceramic insert you want to keep looking decent.
There is a neat trick worth knowing if you cook more than one thing: you can set two liners halfway into the pot, fill each with different ingredients, and finish two dishes in one session. The bags are stacked one at a time in the package so you can pull a single liner without fighting the stack. In my opinion, Syntus 30 suits anyone who makes soups, stews, chilis, or shredded meat in a small slow cooker and dreads the cleanup more than the cooking. Skip it if your slow cooker is larger than 3 quarts, since these are sized for the small end, and skip it entirely if you were hoping for an air fryer accessory — this is not that product and it will not work in a hot-air basket.
Side-by-Side: Which Should You Choose?
• Best for slow cooker cooking → Syntus 30. Sized for 1–3 quart pots and rated for long, moist cooks up to 400°F.
• Best for fewer reorders → DNSSY Air Fryer Parchment. 200 liners in the box versus 30 in the Syntus pack.
• Best for messy, saucy meals → Syntus 30. The bag contains liquid and grease so the pot stays clean.
• Best for bone-in or heavy ingredients → Syntus 30. Reinforced edges and puncture-resistant nylon are built for that.
• Best for even browning and crisping → DNSSY Air Fryer Parchment. The perforations let air circulate rather than steam food under a solid sheet.
• Best for protecting the cookware surface → Syntus 30. The liner sits between food and pot and helps prevent scratches.
• Best for steamer baskets and buns or dumplings → DNSSY Air Fryer Parchment. It fits round, oval and square steamers within the stated size range.
If I had to choose one, I would buy DNSSY Air Fryer Parchment. The reason is simple: the 200-count pack and the perforated, non-stick design solve the most frequent annoyance in a normal kitchen — cleaning an air fryer basket after every batch — and the size range covers square, round and oval baskets plus steamers. Syntus 30 is genuinely good at what it does, and if you cook stews and soups in a small slow cooker, it is the more useful purchase. But for the way most people cook day to day, I think the air fryer liners earn their place faster. Either way, check the current price on Amazon before you commit.
FAQ
No. DNSSY liners are perforated parchment for air fryers, ovens and steamers, while Syntus 30 is a nylon slow cooker liner. Different appliances, different jobs.
They are sized 10.5 x 17.5 inches and listed as fitting 1 to 3 quart round, oval and rectangular pots. If your slow cooker is larger than 3 quarts, these are likely too small.
It is designed for air fryers, baking and steaming, with heat resistance up to 450°F. It is not intended for the long, moist cooking a slow cooker does, so I would not use it there.
It depends on how you cook. DNSSY gives you 200 liners, while Syntus 30 gives you 30. Compare the current prices on Amazon for each and match the count to how often you cook.
