• HEISENLIN Air Fryer Replacement — biggest strength: a food-grade 304 stainless steel crisper plate with a non-stick Teflon coating, a handle for lifting it out, and rubber bumpers so it sits steady in the basket. Biggest trade-off: it only fits cookers that accept an 8.20 × 8.20 in plate, so you have to measure your basket first.
• LU2000 Extra — biggest strength: a genuinely huge 22" × 16.5" × 14" polyester dust jacket with an adjustable drawstring, machine washable and meant for 30–32 quart appliances. Biggest trade-off: it is a cover, not a cooking surface, so it does nothing for the food itself.
• Who HEISENLIN is for: anyone who already owns a compatible Ninja air fryer or Foodi and wants to cook on a proper perforated plate instead of the stock basket bottom.
• Who LU2000 Extra is for: anyone with a big countertop cooker that collects dust, grease haze or pet hair between uses.
• These two are not competitors in the usual sense — one is a cooking accessory, the other is a storage cover.
This is a round crisper plate, 8.20 × 8.20 inches, built from food-grade 304 stainless steel. According to the spec sheet it meets FDA standards and is BPA-free, non-toxic and tasteless — the kind of claim that matters when hot food sits directly on the surface. The finish is a Teflon non-stick coating applied with a double-layer spraying process, which the listing presents as a durability point rather than just a convenience one.
In practice, this is the part that turns a bare air fryer basket into something closer to a grill pan. You drop the plate in, food sits on top of the perforated surface instead of on the basket floor, and air circulates under and around it. That is exactly the arrangement you want for chicken wings, drumsticks, fish fillets, frozen snacks, or anything where you want the bottom to crisp rather than steam. Because it is stainless steel with a non-stick layer, it also takes the abuse of everyday cooking better than a flimsy insert would.
Who should buy it: owners of Ninja AF100, AF101, AF161 or AF150 air fryers, and Ninja Foodi pressure cookers in the OP300, OP301, OP302, OP305, OP401, FD302, FD401, OS301 or OS101 families — anything that takes an 8.20 × 8.20 in crisper plate. Who should skip it: anyone whose basket does not match that footprint. The listing itself says to measure your inner diameter before ordering, and it is right to say so. If your cooker is a different size, this will either rattle or not fit at all, and the non-stick surface is not something you want to force.
LU2000 Extra: Who It's For
LU2000 Extra is a different animal entirely. It is a dust cover — a polyester jacket, black on the outside with a silver lining, sized 22" × 16.5" × 14". The brand positions it around a very specific kitchen problem: the big appliance that lives on the counter and quietly collects everything the kitchen throws at it.
The drawstring is the functional core here. You cinch the bottom and the cover locks down over the appliance, so it stays put instead of sliding off. LU2000 explicitly frames this as size adjustment too — if the cover is bigger than your device, you tighten it, and it also works on a microwave, a large meat slicer, a meat grinder, an outdoor coal smoker or a fish fryer. It is machine washable, which is the only sane way to handle something whose whole job is catching dust and grease haze.
The stated fit is most 30 to 32 quart XL air fryers, Instant Pots, toaster ovens, roasters and similar large units. That is a big footprint, and the listing is honest about the risk: check your dimensions before buying, because a cover that is too small is useless and one that is too loose just looks sloppy even with the string pulled.
Who should buy it: anyone with a 30–32 quart class appliance sitting out in a kitchen that generates vapor, lampblack or pet hair, or anyone storing a large cooker in a garage or shed where dust is constant. Who should skip it: anyone expecting this to do anything for cooking. It does not touch food, it does not go in the appliance, and it is not a replacement part. It is protection, full stop.
Side-by-Side: Which Should You Choose?
• Best for crisp chicken, fish and frozen snacks → HEISENLIN Air Fryer Replacement. The perforated stainless plate with a non-stick coating is designed for exactly that.
• Best for owners of the listed Ninja models → HEISENLIN Air Fryer Replacement. AF100, AF101, AF161, AF150 and the Foodi OP/FD/OS families are named directly.
• Best for protecting a 30–32 quart appliance → LU2000 Extra. Nothing else in this comparison covers that footprint.
• Best for dusty kitchens, garages and pet households → LU2000 Extra. The drawstring plus washable polyester is built for that environment.
• Best for easy cleanup of the accessory itself → HEISENLIN Air Fryer Replacement, since it is dishwasher safe, versus LU2000 Extra, which is machine washable but has to be taken off and washed separately from the appliance.
• Best if you are unsure what you need → decide by question. Do you want to cook better, or store cleaner? Those are the only two jobs on the table.
• Best value depends on your goal — check the current price on Amazon for both, because a cooking accessory and a storage cover are not priced in the same category and the numbers move.
If you are reading this because you want to cook more in your air fryer — better wings, crispier fish, food that does not sit in its own steam — I would buy the HEISENLIN Air Fryer Replacement. It is the one that changes what comes out of the appliance, and the stainless steel, non-stick coating and handle are the features that make it worth owning rather than just tolerating. I would only steer you to LU2000 Extra if your actual problem is a giant appliance gathering dust, because in that narrow job it does that job well. Measure first either way. In my opinion, most people searching this comparison want the plate.
FAQ
how can you cook in an air fryer
You cook by placing food in the basket or on a crisper plate and letting hot air circulate around it, which is why a perforated plate like the HEISENLIN replacement matters — it lifts food off the basket floor so air reaches the underside instead of leaving it soggy. Anything that fits and is not too wet works.
how can you cook chicken in an air fryer
how can you bake in an air fryer
You bake the same way you would in a small oven — the air fryer is essentially a compact convection oven, so small cakes, cookies, biscuits and reheated pastries all work if they fit the basket. A flat, stable surface is what you want, which is the role a plate like the HEISENLIN one plays for savory food.
how can you cook eggs in an air fryer
Eggs are doable — think baked eggs in a small dish, frittata-style mixtures, or egg bites in a mold rather than frying a loose egg. They need a contained surface, so a small oven-safe dish sitting on a crisper plate is the practical setup. Keep the temperature moderate and check early, since eggs set fast in moving hot air.
