• Mistifi Air Fryer Silicone — biggest strength: two square liners in the box, a 5.8–8 qt fit range, and a 482°F heat ceiling that covers oven, microwave and steamer use as well as air frying.
• Mistifi Air Fryer Silicone — biggest trade-off: it is a general-purpose square, so it will not sit flush in a small round 4 qt basket and you get less of a tailored fit.
• Belfort Etech Silicone Liner — biggest strength: purpose-built for the circular Ninja AF101, with a thicker 0.1 inch wall and 0.3 inch raised base lines aimed at airflow and even browning.
• Belfort Etech Silicone Liner — biggest trade-off: one liner, one shape, one machine — it is not the pick for a large square basket or a multi-appliance kitchen.
• Who each pick is for: Mistifi for anyone with a 5.8–8 qt air fryer who wants spares and multi-appliance flexibility; Belfort Etech for the Ninja AF101 owner who wants a liner that drops in and stays put.
Mistifi's liner is a square silicone bowl measuring 8.5 x 7.7 x 2.6 inches, sold as a two-pack. The material is food-grade silicone rated to 482°F, non-stick, BPA free and odorless, and the brand positions it squarely as a reusable swap for disposable parchment. The raised lines molded into the base are the functional detail worth caring about: they lift food slightly off the floor of the liner so grease can drain away and hot air can move underneath, which is the difference between soggy bottoms and evenly cooked ones. There are handles on both sides, so you can lift the whole basket out rather than fishing food out piece by piece.
The two-pack matters more than it sounds. One liner can be in the dishwasher while the other is in use, and if you cook savoury and sweet in the same week you can keep them separate. Cleaning is the easy part — the silicone is flexible enough to invert and rinse, or it goes in the dishwasher. Mistifi also lists it for microwave baking, barbecue, steamer lining and general food placement, so it earns its cupboard space beyond the air fryer.
Buy it if you own a 5.8 to 8 quart air fryer of almost any brand, you want a spare liner on standby, and you like the idea of one accessory that covers the air fryer, oven and microwave. Skip it if you have a small round 4 qt basket — a square liner in a round basket leaves gaps and wastes cooking area — or if you specifically want a liner engineered around one machine's airflow. In my opinion this is the more versatile of the two, but versatility is exactly what makes it a compromise on fit.
Belfort Etech went the opposite direction: one machine, one liner, done properly. This is a circular silicone liner at 8.2 x 8.2 x 3.5 inches, built for the Ninja AF101 4 quart air fryer, with a 3.8 liter capacity that matches the basket it lives in. The wall is 0.1 inch thick, which is the spec that keeps the liner from collapsing when you lift a full load of food — a thin liner folds and spills; this one holds its shape.
The base is where the design gets interesting. Belfort Etech molds 0.3 inch high silicone lines into the bottom, and the stated purpose is twofold: keep food off the base so heat distributes more evenly and the bottom of your food does not scorch, and keep air circulating so you still get the crisping you would get cooking directly in the basket. That is the honest trade-off of any liner — you are adding a layer between food and moving hot air — and this design is a deliberate attempt to give that layer back.
Material-wise it is food-grade, BPA free, non-toxic silicone rated to 464°F and down to -60°F, so it handles freezing as happily as frying. It is dishwasher safe and flexible enough to invert and rinse. It comes as a single liner. Buy it if you own a Ninja AF101 and want something that fits the round basket exactly, holds its shape under a full load, and cleans in seconds. Skip it if your air fryer is a different model or a larger square basket, because a tailored circular liner is only tailored to one thing.
• Best for a 5.8–8 qt square basket → Mistifi Air Fryer Silicone. The 8.5 x 7.7 inch footprint is sized for that range.
• Best for the Ninja AF101 4 qt → Belfort Etech Silicone Liner. 8.2 x 8.2 inches, circular, matched to a 3.8 liter basket.
• Best for getting two liners → Mistifi Air Fryer Silicone. It ships as a two-pack; Belfort Etech ships as one.
• Best for holding shape under a heavy load → Belfort Etech Silicone Liner. The 0.1 inch thickness is called out specifically for sturdiness.
• Best for higher heat headroom → Mistifi Air Fryer Silicone. 482°F versus 464°F, though both clear normal air fryer temperatures comfortably.
• Best for airflow and even browning in a round basket → Belfort Etech Silicone Liner. The 0.3 inch raised base lines are the more aggressive airflow design.
• Best for multi-appliance cooking → Mistifi Air Fryer Silicone. Oven, microwave, steamer and barbecue use are all listed; Belfort Etech is scoped to the AF101.
• Best for freezer-to-fryer flexibility → Belfort Etech Silicone Liner. It is rated down to -60°F as well as up to 464°F.
• Best for a gift or a first silicone liner → Mistifi Air Fryer Silicone. Two pieces and broad compatibility make it the safer thing to hand someone whose air fryer model you do not know.
If I had to pick one, I would buy the Mistifi Air Fryer Silicone — not because it is better engineered, but because it fits more kitchens. Two liners, a 5.8–8 qt range, a 482°F ceiling and oven and microwave use give it far more chances to earn its place in a drawer.
That said, if you own a Ninja AF101, I would go the other way and take the Belfort Etech Silicone Liner. The 0.1 inch wall and the 0.3 inch raised base lines are the kind of detail that only shows up when a liner is designed for one basket, and a flush fit beats a universal fit every time you lift a full load of food.
how to clean air fryer silicone liner
Let it cool first, then invert the liner and rinse. Both liners here are flexible silicone, so you can turn them inside out to push out grease and residue, then hand wash or put them in the dishwasher — both are listed as dishwasher safe.
how to use air fryer silicone liners
Set the liner in the basket, add your food in a single layer, and cook as normal. The raised lines on both the Mistifi and Belfort Etech bases are there to lift food off the floor of the liner so grease drains and hot air still moves underneath.
how to use air fryer silicone liners ninja
For a Ninja AF101, use the Belfort Etech liner — it is cut circular at 8.2 x 8.2 inches for that 4 quart basket and its 3.8 liter capacity. The Mistifi square is the better match for larger 5.8–8 qt machines rather than a small round Ninja basket.
how to clean air fryer silicone liner with baking soda
Make a paste from baking soda and a little water, work it into stained or greasy spots with a soft sponge, then rinse thoroughly and wash as usual. Avoid abrasive scrubbers on the non-stick silicone surface, and check the current price on Amazon before you buy either liner.
