If you want a reusable liner that turns your air fryer basket into a near-self-cleaning surface for big 5–8 QT machines, choose Boribim 9; if you need tiny silicone feet sleeves that stop racks and dehydrator trays from sliding and scratching your appliance, choose Mobestech Silicone Air Fryer.
• Boribim 9 — biggest trade-off: it's a liner, not a hardware fix. It won't stabilize a wobbly rack, and it only really fits square baskets in that 5–8 QT range.
• Mobestech Silicone Air Fryer — biggest strength: an 8-pack of compact silicone feet sleeves/bumpers (1.77 x 1.25 x 0.27 in) that hold racks in place, quiet movement, protect surfaces from scratches, and go in the dishwasher.
• Mobestech Silicone Air Fryer — biggest trade-off: it does nothing for mess or cleanup inside the basket. If your goal is "less scrubbing," these little pads won't help.
• Who each pick is for: Boribim 9 is for anyone tired of scraping grease off a large square air fryer basket; Mobestech is for anyone whose rack slides, rattles or scratches — especially dehydrator users.
Boribim 9 is a cooking-surface upgrade. You get two square silicone liners — upper size 9 inches, bottom size 8 inches, 2.36 inches tall — that fit 5 to 8 QT air fryers. In my opinion, the square shape is the smart part: round liners waste the corners of a square basket, and square ones sit flatter with less folding and pinching.
The material story is straightforward. It's food-grade silicone, BPA free and tasteless, rated to 464 °F (240 °C), and the product has passed FDA testing. At roughly 67 mil thick, it's a substantial liner rather than a flimsy sheet. The bottom has raised lines that lift food slightly, which lets hot air move underneath and lets grease drain away instead of pooling. Cleanup is the headline: it keeps residue and grease off the basket, and it's completely dishwasher safe.
Buy Boribim 9 if you cook in a 5–8 QT square air fryer, hate scrubbing, and want to bake, roast or reheat without lining the basket with foil or parchment every time. It also works in a toaster, steamer, oven, Instant Pot or microwave, so it earns drawer space beyond the air fryer.
Mobestech Silicone Air Fryer: Who It's For
Mobestech Silicone Air Fryer is a small-parts accessory, and it's honest about that. You get eight silicone feet sleeves, each measuring 1.77 x 1.25 x 0.27 inches — about the size of a thick coin. They slip onto rack feet or sit under dehydrator trays to hold things steady while the machine runs.
What that buys you is stability and protection. The sleeves reduce rack movement during cooking, which supports more even airflow and more consistent results; a rack that shifts mid-cook can block air or tilt food. The angled buffer-pad structure also keeps metal feet from scratching or denting appliance surfaces — a real concern if you stack trays in a cabinet or slide racks in and out daily. They're dishwasher safe and reusable, so maintenance is basically nothing.
Buy Mobestech if you use dehydrator racks, notice your air fryer rack sliding or rattling, or want a cheap insurance layer against scratches on the appliance body and your countertop. The 8-pack matters here: it gives you spares and enough pieces to outfit multiple racks at once.
Skip it if your complaint is grease and food residue inside the basket — that's Boribim's job, not this one. Also skip it if you're looking for a full replacement rack; these are sleeves and bumpers, not structural parts.
• Best for less scrubbing → Boribim 9. Non-stick silicone liners keep grease and burnt residue off the basket, and they're dishwasher safe.
• Best for a stable, quiet rack → Mobestech Silicone Air Fryer. Feet sleeves cut rack movement and the noise and uneven cooking that come with it.
• Best for large square air fryers (5–8 QT) → Boribim 9. The 9-inch square footprint is built for that size class.
• Best for dehydrators and multi-rack setups → Mobestech Silicone Air Fryer. Eight bumpers cover several racks at once.
• Best for surface protection → Mobestech Silicone Air Fryer. The buffer-pad design guards against scratches and dents.
• Best multi-appliance flexibility → Boribim 9. It's rated for toaster, steamer, oven, Instant Pot and microwave use, not just the air fryer.
• Best for baking, roasting and holding food → Boribim 9. It works as a liner for baking and serving, not just air frying.
• Best for small, easy-to-store extras → Mobestech Silicone Air Fryer. At under 2 inches long per piece, they disappear into a drawer.
I'd buy the Boribim 9 liners first. In my opinion, they solve the problem most air fryer owners actually have — a greasy, sticky basket that's a pain to clean — and the 5–8 QT square sizing, 464 °F heat rating and dishwasher-safe silicone make them a genuinely useful everyday accessory rather than a gadget.
That said, Mobestech Silicone Air Fryer is the better pick if your issue is mechanical, not culinary: a rack that slides, rattles or scratches. The two aren't really competitors — they fix different problems. If you can only grab one and you cook in a large square air fryer, go with Boribim. Check the current price on Amazon before deciding, since both are inexpensive accessory purchases.
FAQ
They do different jobs, so "better" depends on your problem. Boribim 9 wins for mess-free cooking and easy cleanup; Mobestech wins for rack stability, reduced movement and surface protection. Buy the one that matches your complaint.
It fits 5 to 8 QT air fryers. The liner measures 9 inches across the top, 8 inches at the base, and 2.36 inches tall, so it's meant for larger square baskets. If you have a small or round basket, it likely won't sit well.
Boribim 9 includes 2 square silicone liners (black and brown). Mobestech Silicone Air Fryer includes 8 silicone feet sleeves. Both are reusable.
Yes. Boribim 9 liners are completely dishwasher safe, and Mobestech feet sleeves can go in the dishwasher too. That keeps hand-washing to a minimum for both.
