• HEISENLIN's biggest strength: a tight, single-purpose fix — three food-grade 304 stainless steel self-tapping screws sized for the Instant Vortex Plus 4QT basket.
• HEISENLIN's biggest trade-off: it does exactly one job. If your air fryer isn't a Vortex Plus 4QT, these screws aren't for you.
• Kispog's biggest strength: a 3-pack of stainless airflow trays plus a magnetic mesh splatter guard that blocks grease and burnt odors while letting hot air circulate.
• Kispog's biggest trade-off: it's built for the Instant Pot 10QT air fryer and its 10.2" x 8.97" trays — it's an accessory kit, not a repair part.
• Buy HEISENLIN if you own an Instant Vortex Plus 4QT and need replacement hardware for the basket.
• Buy Kispog if you own a 10QT Instant air fryer and want better crisping, dehydration, and less cleanup.
HEISENLIN is a repair-and-replace product, not a cooking upgrade. It's a three-pack of self-tapping screws made from food-grade 304 stainless steel, and the whole point is that they're rated for high heat and built to sit inside a cooking appliance. The material matters here — 304 stainless is the grade you actually want near food and near a heating element, and the listing notes it's BPA-free and meets FDA standards, non-toxic and tasteless.
Compatibility is the entire story with this one. These screws are designed for the Instant Vortex Plus 4QT air fryer basket. Not the 10QT, not the Vortex Plus in other sizes, not a generic basket — the 4QT. If that's your machine and you've got a screw that's stripped, lost, or rattling, this is the kind of part that saves you from buying a whole new basket over a tiny piece of hardware. You get three, so you've got spares.
Kispog Air Fryer Accessories: Who It's For
Kispog plays a completely different game. This is a 3-pack of stainless steel airflow cooking trays plus a magnetic splatter guard, designed for the Instant Pot 10QT air fryer. The trays are uncoated 304 stainless with no Teflon and no BPA, and they're built around a precision grid — roughly 6x10mm — that lets hot air move 360° around your food. In practice that means food crisps more evenly and the kit claims about 20% faster crisping, which lines up with what better airflow usually does.
The splatter guard is the sleeper feature. It's a fine stainless mesh that blocks around 95% of grease splatter, which keeps fat off your heating coils and cuts down on that burnt smell that lingers in a kitchen after a messy cook. It's magnetic, so it sits in place as a barrier between the food and the element.
The trays unlock real multitasking. Because you get three, you can dehydrate vegetables and fruit, make beef jerky, or run pizza, bacon, and baking in batches instead of one round at a time. Heat resistance goes up to 480°F/230°C, and the fit is sized for 10.2" x 8.97" trays within a tight tolerance, so it's meant for that 10QT Instant body specifically.
Cleaning is where I'd flag a trade-off. The kit is dishwasher-safe, but Kispog is specific about method: spray with a degreasing spray, let it stand about ten minutes, then top-rack dishwasher or rinse. Do not use a brush, and hand washing isn't recommended. That's an easy routine once you know it, but it's a routine — not a toss-it-in-and-forget-it accessory. Skip this if you own a 4QT Vortex Plus or any non-10QT machine.
• Best for fixing a loose or missing basket screw → HEISENLIN Air Fryer Screws. It's a purpose-built replacement for the Instant Vortex Plus 4QT basket.
• Best for improving how your air fryer cooks → Kispog Air Fryer Accessories. Airflow trays and a splatter guard change results, not just hardware.
• Best for Instant Vortex Plus 4QT owners → HEISENLIN. The screws are sized for that exact basket.
• Best for 10QT Instant air fryer owners → Kispog. Trays fit 10.2" x 8.97" and the kit is built for the 10QT body.
• Best for reducing grease splatter and burnt odors → Kispog. The mesh guard blocks roughly 95% of splatter and shields the heating coils.
• Best for dehydrating and batch cooking → Kispog. Three trays let you dry fruit and veg, make jerky, or cook multiple items at once.
• Best for material safety in a hot appliance → both. HEISENLIN uses food-grade 304 stainless rated for high heat; Kispog uses uncoated 304 stainless, Teflon- and BPA-free, rated to 480°F/230°C.
• Best for a no-fuss cleaning routine → HEISENLIN. Three small screws versus trays that need a degreaser spray and dishwasher cycle.
In my opinion, the right pick comes down to one question: are you repairing or upgrading? If you own an Instant Vortex Plus 4QT and something's wrong with the basket hardware, I'd buy the HEISENLIN screws — it's a targeted fix at the exact size you need, in the right material, with two spares. If you own a 10QT Instant air fryer and want better crisping, dehydration, and less splatter mess, I'd buy the Kispog kit. For most people reading this who aren't chasing a broken screw, the Kispog accessories do more for everyday cooking.
how to disassemble instant vortex air fryer
Disassembly depends on your model, and you should always unplug the unit and let it cool first. If you're working on the Instant Vortex Plus 4QT basket, the HEISENLIN self-tapping screws are replacement hardware sized for that basket — so if you're removing and refitting basket screws, that's the part to have on hand.
how to clean instant vortex air fryer
For the basket and any stainless parts, warm soapy water and a soft cloth are the safe route — avoid abrasive brushes on uncoated stainless. If you're using the Kispog kit, follow its method: spray with a degreaser, let it sit about 10 minutes, then top-rack dishwasher or rinse. Kispog specifically says not to use a brush and doesn't recommend hand washing.
how to use instant vortex air fryer
Load food in a single layer so hot air can move around it, then set your time and temperature. The Kispog airflow trays are designed around this idea — the mesh grid allows 360° circulation for more even crisping, and the three-tray setup lets you dehydrate or batch-cook several items at once.
how to reset instant vortex air fryer
Resetting is a control-panel action, not something either product changes — unplug the unit for a short period and plug it back in to clear a fault on most models. Neither the HEISENLIN screws nor the Kispog trays have any electrical function; they're replacement hardware and cooking accessories respectively.
