These two accessories get lumped together because they both live inside an air fryer basket, but they solve completely different problems. One is about cleanup and convenience. The other is about airflow, browning and structure. If air fryer onion rings are your thing — or frozen fries, or anything you want genuinely crisp — that distinction matters more than it sounds.
• VITAPREP 200-Pack — biggest strength: 200 unbleached parchment liners sized for the Ninja Crispi 4-in-1 Portable Glass Cooking System, so grease and crumbs never touch the basket.
• VITAPREP 200-Pack — biggest trade-off: it's disposable, it's single-model sized (8–9 inches), and it does nothing for crispiness — it's a barrier, not a cooking surface.
• BildeeMait Non- Air Fryer — biggest strength: a perforated carbon steel crisper plate with a handle and non-stick coating that you reuse, dishwasher-clean and pull out in one motion.
• BildeeMait Non- Air Fryer — biggest trade-off: it's a single-piece replacement part fitted to specific models (AF100, AF150, FD401, OP300, OP500), and the non-stick surface needs gentle care.
• Pick VITAPREP if you own a Ninja Crispi and hate scrubbing.
• Pick BildeeMait if you own one of the listed fryer models and want better browning and crisp texture from the same basket.
VITAPREP is selling one thing, and it sells it well: the end of scrubbing. The 200-pack contains 100 + 100 unbleached parchment sheets made from raw wood pulp, coated with food-grade silicone so food releases without sticking. They're rated heat-safe to 450°F (230°C), free of BPA and fluorescent agents, and sized at 8–9 inches to sit inside the Ninja Crispi 4-in-1 Portable Glass Cooking System (model FN101 compatible). The sheet count is the headline: 200 liners is months of cooking for most households, which is why the value story here is about time saved rather than anything else.
The way it works is almost too simple. You drop a liner into the basket, put food on top of it, cook, then throw the liner away with the grease still on it. Because the liner traps oil and crumbs, the basket underneath stays essentially untouched. That's a real difference from perforated papers, which let grease through, and from reusable silicone baskets, which you still have to wash. If your air fryer cleanup routine is the reason you cook in it less often than you'd like, this is the accessory that removes the excuse.
Where it fits best: light, weighted foods that hold the liner down — onion rings, fries, cookies, pastries, pizza crusts, even a wrapped sandwich. It's also a natural fit if you cook in small batches several times a day and don't want to wash anything in between.
Who should skip it: anyone who doesn't own a compatible Ninja Crispi, since the sheets are cut for that footprint. And anyone chasing maximum crispness — parchment is a flat barrier, so air circulates above the food rather than under it. The manufacturer is explicit about the safety rules too: always place food on the liner to weigh it down, never use it empty, never expose it to a direct flame, and keep the fryer under 450°F. Follow those and it's a genuinely hassle-free accessory. Ignore them and a lightweight liner can lift and touch the heating element.
BildeeMait takes the opposite approach: instead of throwing something away, you upgrade the surface you cook on. This is a single crisper plate — a replacement grill pan — made from carbon steel with a non-stick coating, measuring 8.19 inches (about 20.8 cm). It's built to fit AF100, AF150, FD401, OP300 and OP500 models, and the brand is upfront that you should check your size chart before ordering, because fit is the whole ballgame with a part like this.
The design detail that matters most is the perforated surface. Holes mean hot air moves through the plate and around the food, not just over the top of it. That's how you get browning on the underside of onion rings, fries, chicken, steak or roasted vegetables instead of a pale, slightly steamed result. The second detail is the handle. It sounds minor until you've tried to fish a hot, greasy plate out of a basket with tongs — the handle lets you lift the whole thing out in one motion and serve straight from it.
Cleaning is where it earns its keep against disposable options. The plate is dishwasher safe, so the routine is: cook, lift out, load the dishwasher. The one maintenance rule is real, though — skip abrasive cloths and metal scrubbers, because they'll strip the non-stick coating and you'll be back shopping for a replacement.
Who should buy it: owners of the listed models who want a reusable cooking surface and noticeably better texture on foods that are supposed to be crisp. It's also a smart buy if your original crisper plate has lost its coating or gone missing.
Side-by-Side: Which Should You Choose?
• Best for zero-scrub cleanup → VITAPREP 200-Pack. Grease and crumbs come out with the liner.
• Best for crispiness and browning → BildeeMait Non- Air Fryer. The perforated carbon steel surface lets air circulate underneath the food.
• Best for air fryer onion rings → BildeeMait Non- Air Fryer, in my opinion — onion rings need airflow on both sides to go crunchy rather than soggy. VITAPREP still works if you're mainly avoiding cleanup and don't mind a softer underside.
• Best for long-term cost per use → BildeeMait Non- Air Fryer. One reusable plate versus a finite stack of 200 sheets.
• Best for convenience on busy days → VITAPREP 200-Pack. No washing, no thinking, straight into the bin.
• Best for Ninja Crispi owners → VITAPREP 200-Pack. The 8–9 inch liners are cut for that glass cooking system; the BildeeMait plate is not.
• Best for AF100 / AF150 / FD401 / OP300 / OP500 owners → BildeeMait Non- Air Fryer. Fitment is model-specific, so check yours first.
• Best for high-heat roasting up to 450°F → VITAPREP 200-Pack, which is explicitly rated to that ceiling.
• Best if you hate maintenance rules → VITAPREP 200-Pack. The BildeeMait plate's coating demands gentle handling.
If I owned a compatible AF100, AF150, FD401, OP300 or OP500, I'd buy the BildeeMait Non- Air Fryer crisper plate. In my opinion it's the more useful accessory, because it changes how the food actually cooks rather than just how the basket looks afterward — and onion rings, the food most people search this comparison for, are exactly the case where a perforated surface wins. It's reusable, dishwasher safe and lifts out by its handle.
That said, VITAPREP is the right call in one specific situation: you own a Ninja Crispi and cleanup is the reason you avoid using it. There, 200 liners at 450°F heat resistance is a genuinely good answer. Neither is a bad product — they're just answering different questions.
FAQ
how to air fry onion rings
how to air fry onion rings frozen
Frozen rings go straight in — no thawing needed, which is the whole appeal. Give them a little space, cook a few minutes longer than you would fresh, and flip once so both sides brown. If you line the basket with parchment, put the food directly on the liner so it stays weighted down, as VITAPREP instructs.
how to air fry onion rings in oven
If you're using an oven's air fry or convection mode, set the rings on a perforated tray or rack over a sheet pan so air circulates underneath. A single layer and a mid-way flip matter just as much as they do in a basket fryer. The same logic as the BildeeMait plate applies: airflow underneath is what turns a ring crunchy.
how to air fryer onion rings
Keep it simple: preheat briefly, arrange rings in one layer, cook at high heat, and shake the basket at the halfway mark. Skip the oil-heavy dredge if you want them to crisp rather than sit heavy. Whichever accessory you use, the goal is the same — maximum hot air contact on all sides of the ring.
