If you want to protect your countertop from hot appliances and slide heavy machines around without scratching the surface, choose Hkvoxim Heat Resistant Mat; if you need a reusable liner that keeps food and grease from sticking inside your air fryer basket, choose PINTAUR Square Silicone Air.
• Hkvoxim Heat Resistant Mat — biggest strength: a 5-piece set of 17 x 12 inch felt-and-silicone mats rated to resist heat up to 570°F, so they sit under the appliance rather than inside it.
• Hkvoxim Heat Resistant Mat — biggest trade-off: it does nothing for the inside of your air fryer, and the felt side should not go in the dishwasher.
• PINTAUR Square Silicone Air — biggest strength: two food-grade silicone liners with raised bottom strips that lift food off grease and promote airflow, both dishwasher-safe.
• PINTAUR Square Silicone Air — biggest trade-off: it only fits square baskets in the 5–6.5 QT range, so you have to measure before you buy.
• Who Hkvoxim Heat Resistant Mat is for: anyone who wants to shield a marble or wood countertop from a hot air fryer, coffee maker, blender or toaster.
• Who PINTAUR Square Silicone Air is for: air fryer owners with a compatible square basket who are tired of scrubbing burnt-on residue.
The Hkvoxim Heat Resistant Mat solves a problem most people only notice after the damage is done: the exposed hot bottom of an air fryer or coffee maker leaving marks and stains on a countertop. This mat is built to sit in between. It's made of heat-resistant felt with a silicone surface, and the manufacturer rates it to resist temperatures up to 570°F. In my opinion, that headroom is the whole point — it's well above what a typical countertop appliance throws downward, so you're not gambling with your marble.
It's also a 3-in-1 design by intent. The felt side goes down and slides, so you can pull a heavy appliance forward without lifting it. The silicone side faces up and grips, which keeps the machine from wandering while it runs. That combination is genuinely useful in a small kitchen where you shuffle the same appliance between the counter and a cabinet. Each mat measures about 17 x 11.8 x 0.2 inches, so there's enough footprint for a full-size air fryer, and you can trim them with scissors to match the base of whatever you're setting down.
Where this product really earns its place is in the quantity. You get five mats in black — one for the air fryer, one for the coffee maker, one for the blender, and spares for the microwave or toaster. Black is a smart choice because it disappears under appliances instead of fighting your kitchen's look. You can also rotate and reposition appliances in any direction you want, which a fixed sliding tray won't let you do.
PINTAUR Square Silicone Air: Who It's For
The PINTAUR Square Silicone Air is aimed at a completely different pain point: the inside of the basket. These are reusable liners made of food-grade silicone that the brand describes as odorless, non-toxic, BPA-free and smoke-free, with a stated heat tolerance up to 450°F. They catch food residue and grease so the basket itself stays cleaner, and because they're dishwasher-safe, cleanup is a matter of dropping them in rather than scrubbing.
The design details are where this liner separates itself from a plain silicone insert. The walls are thick and sturdy, which the brand says resists deformation — that matters because thin liners flop and spill. More interesting are the raised silicone strips on the bottom. They lift food slightly above the oil that renders out during cooking, which reduces how much fat your food sits in, and the same raised pattern opens up airflow underneath. PINTAUR's claim is that this shortens cooking time and saves energy. I'd treat the energy-saving part as a reasonable design intent rather than a guaranteed result, but the grease-separation benefit is straightforward physics.
Sizing is the part you cannot skip. The top measures 8.46" x 8.46", the bottom 7.68" x 7.68", and the height is 2.36". PINTAUR says these fit square air fryer baskets up to 8.9 inches, which covers 5–6.5 QT models like the Ninja AF181 and AF141. Critically, they are not compatible with the COSORI CAF-DC601 (6 QT) or the Instant Vortex Plus (6 QT). PINTAUR explicitly asks buyers to measure the top of their basket before ordering, and that's the right advice — a square liner in a round or oversized basket is a bad fit.
Beyond the air fryer, these work in toasters, steamers, ovens, electric pressure cookers and microwaves, and you can use them for baking, roasting, frying or just serving. You get two in the pack, both black. Who should skip it? Anyone with a round basket, a very large fryer, or one of the two incompatible models named above. And if your countertop is the thing getting scorched, this liner won't help you at all.
Side-by-Side: Which Should You Choose?
• Best for keeping your air fryer basket clean → PINTAUR Square Silicone Air. It lines the basket and catches residue and grease.
• Best for greasy foods like wings or bacon → PINTAUR Square Silicone Air. The raised strips separate food from rendered fat.
• Best for sliding heavy appliances out from under a cabinet → Hkvoxim Heat Resistant Mat. Felt down, silicone up.
• Best if you own multiple countertop appliances → Hkvoxim Heat Resistant Mat. Five mats cover several machines and give you spares.
• Best if you hate hand-washing → PINTAUR Square Silicone Air. It's dishwasher-safe; the Hkvoxim mat is not.
• Best if you're unsure about fit → Hkvoxim Heat Resistant Mat. You can DIY-trim it to the base of almost anything.
• Best if you own a Ninja AF141 or AF181 → PINTAUR Square Silicone Air. Those are the models it's built around.
If I had to pick one, I'd buy the Hkvoxim Heat Resistant Mat. Here's my reasoning: it's the more forgiving purchase. You get five mats, you can trim them to fit, and they work under a coffee maker, blender, microwave or toaster — not just one specific air fryer. There's no compatibility list to fail. The PINTAUR liner is the better tool for a narrower job, and if you own a compatible Ninja and your real frustration is scrubbing the basket, it's the smarter buy. But as a single purchase that helps across the whole kitchen, I'd take the mats.
That's the scenario it's designed for. The felt layer blocks heat from the hot bottom of the appliance from reaching the surface directly, and the manufacturer rates it to resist up to 570°F. Lay it felt-side down so it slides.
Will the PINTAUR Square Silicone Air fit my air fryer?
Only if your basket is square and in the 5–6.5 QT range, up to about 8.9 inches. The liner is 8.46" across the top. It's listed as incompatible with the COSORI CAF-DC601 (6 QT) and Instant Vortex Plus (6 QT), so measure your basket top first.
No — and that's the main thing to understand. The Hkvoxim mat goes under the appliance to protect the countertop. The PINTAUR liner goes inside the air fryer basket to protect the basket and separate food from grease. Many people would benefit from owning both.
The PINTAUR liner is the easier one — it's fully dishwasher-safe. The Hkvoxim mat should not go in the dishwasher, so plan on wiping it down by hand. If price matters to you, check the current price on Amazon using the button on this page before deciding.
