• MOWETOO 4Pcs — best for holding disposable parchment liners flat with a single continuous magnet strip; pick this if you want a four-pack of non-segmented, food-grade silicone magnets that cover more of the liner edge at once.
• Mity rain Air Fryer Magnets — best for messy, greasy cooking you'd rather rinse than scrub; pick this if you want a magnet rated to 464°F (240°C) with a smooth silicone surface that wipes clean or goes in the dishwasher.
• K KERNOWO Air Fryer Magnets — best for high-heat cooking and thicker liners; pick this if you want a magnet rated to about 570°F (300°C) that keeps its magnetic strength and works with any metal-component basket.
• BOXOB 2 — best for flexibility across different basket shapes; pick this if you want two long strips plus four small hexagonal magnets you can arrange wherever your liner needs pinning down.
This is a pack of four rectangular black silicone magnets designed to sit along the rim of a metal air fryer basket and pin a disposable parchment liner in place. The headline feature is the non-segmented design. Instead of several small magnets with gaps between them, each piece is one continuous strip, so the contact area along the liner edge is larger and the hold is more consistent. In daily use, that matters more than it sounds: a liner that only touches down in a few spots can still catch the circulating hot air and flip up at the corners, and that's exactly the moment you end up with scorched paper near the heating element.
The material is food-grade silicone that the maker describes as heat resistant, non-toxic and odor-free, and it's thickened. Thick silicone does two useful things here — it insulates a bit, which cuts down the chance of a burn when you're handling the magnets after cooking, and it resists deforming under heat so the strips stay flat against the basket instead of curling away. It's also soft enough that it won't scratch the basket coating, which is a real concern with bare metal clips.
Setup is about as simple as it gets: lay the liner in the basket, drop the magnets along the edge, and they snap to the metal. No threading, no tearing the paper, and the design leaves airflow open so hot air still circulates around the food. When you're not cooking, they'll stick to a fridge or any other metal surface, so they're not dead weight in a drawer.
The trade-off is compatibility, and this one is important. These only work on magnetic metal or iron baskets. Ceramic, aluminum and non-magnetic stainless steel baskets won't hold them at all — the magnets simply won't grab. If your air fryer has a coated non-stick basket, check with a fridge magnet before you commit.
Mity rain's entry is a single magnet in a red flower colorway, sized Large, made from food-contact-grade silicone with a heat resistance of up to 464°F (240°C). That temperature figure is the number to focus on: it covers the range most air fryer recipes actually run at, and the silicone is specified not to deform or melt even after repeated cycles. The maker also states it stays clean and odor-free with repeated use, which is the part that tends to fail first on cheap silicone — it picks up yesterday's fish and never lets go.
The build pairs a strong magnet inside a heat-resistant core, and the silicone body protects the basket from scratches. The practical benefit of the magnetic quick-release system is speed: it attaches in seconds and comes off just as fast, so you're not fighting a liner that's welded itself to the basket with grease. Cleaning is the standout here. The smooth silicone surface resists grease and food residue, so a wipe does most of the work, and it's dishwasher-safe when you'd rather not bother.
Who is this for? I'd point it at someone who cooks greasy proteins — wings, drumsticks, bacon — and wants an accessory that doesn't add a scrubbing step. A single magnet also suits anyone with a smaller basket who only needs to pin one edge of the liner.
Two things to weigh. First, it's one item, not a set, so if you want to secure a full liner edge you may find one magnet isn't enough coverage. Second, the fit is limited: it works with iron baskets only, across brands like Ninja, Philips and Cosori, but it won't attach to ceramic, aluminum or non-magnetic stainless steel.
K KERNOWO sells these as a 12-piece set of red rectangular silicone buckles, and the spec that separates them from the pack is heat tolerance: built-in high-temperature-resistant magnets rated to withstand up to about 570°F (300°C) without losing magnetic strength. That's the highest figure across these four, and it's the reason I'd steer high-heat cooks here. Air fryers routinely run hot, and a magnet that weakens with heat is a magnet that stops holding your liner halfway through a roast.
The body is food-grade silicone — soft, durable, heat-resistant, and specified not to deform or release harmful substances at temperature. Softness is doing real work: these sit against the basket wall, and a hard clip would eventually mark the coating.
Compatibility is broad. K KERNOWO says these work with all air fryer brands and models that have metal components, and gives you a straightforward pre-purchase test — hold a regular magnet against your basket, and if it sticks, these will work. That's a sensible check because the underlying physics is the same.
Operation is place-and-go: set the buckles on the edge to trap the parchment, then rinse them with water afterward. The maker notes they won't deform or rust and are built to survive frequent use.
The trade-off is the count versus your actual needs. Twelve buckles is a lot of pieces to keep track of for a single basket, and small parts in a kitchen drawer have a way of migrating. If you'd rather have fewer, larger pieces, a strip design suits you better. And the same metal-only limitation applies — non-magnetic baskets are out.
BOXOB takes a mixed-size approach. You get two sets, each containing two long strip magnets and four small hexagonal magnets — six pieces per set, twelve total. The long strips measure 4.65 inches long and 0.24 inch thick; the hexagons are 0.54 inch long and 0.24 inch thick. That combination is the whole point: long strips handle the straight runs along a rectangular basket, and the small hexagons tuck into corners or fill gaps where a full strip won't sit flat.
Material is silicone over a durable magnet, specified to hold up at high temperatures while keeping its grip and flexibility through repeated use. The soft silicone protects the basket from scratches. The maker's stated benefit is even heat distribution — the reasoning being that a liner held flat won't shift mid-cook and block airflow unevenly.
Use is straightforward: the buckles attach instantly to any metal air fryer component, hold the paper through the cook, and wipe clean afterward.
Who should consider this? I'd recommend it for someone with an oddly shaped basket, or someone who wants to keep spare magnets in a second kitchen. The size variety gives you options a single-size pack doesn't.
The honest trade-offs: the small hexagonal pieces are genuinely small, which means more fiddly placement and more chance of losing one. The same iron-basket-only rule applies — the maker flags it directly. And since the strips are shorter than a full basket edge, on a large basket you'll likely need two pieces per side.
I compared the published specs and features for each option — magnet construction, silicone grade, stated heat resistance, piece count and basket compatibility — and ranked them on how those specs translate into holding a parchment liner safely in everyday cooking. The order above is my independent editorial opinion; no brand paid for placement or had any input into it.
The silicone bodies on all four picks are soft, and each maker states they won't scratch or damage the basket surface. The bigger concern isn't scratching — it's whether the basket is magnetic at all.
Hold an ordinary fridge magnet against the inside of the basket. If it sticks, magnetic buckles will hold. If it doesn't, your basket is ceramic, aluminum or non-magnetic stainless steel, and none of these products will attach.
All four are designed to sit along the liner edge rather than across the basket, so hot air still circulates around the food. Keeping the liner flat is itself the airflow benefit — a liner that lifts and folds is what blocks air and burns.
They'll stay attached to the metal, but rinsing or wiping them after greasy cooks keeps the silicone from holding onto odors and residue. Mity rain's version is dishwasher-safe, which makes that easier.
