• LU2000 Egg Shape Airfryer — biggest strength: a full-wrap 210D polyester cover with a lotus-leaf-like waterproof finish and silver lining, sized for cone-shaped appliances with a big handle. In my opinion it's the more useful buy if your air fryer sits out on the counter collecting dust and kitchen grease.
• LU2000 Egg Shape Airfryer — biggest trade-off: it's a cover, not a cooking accessory — it does nothing for food, and you must measure your appliance carefully because fit depends on diameter and handle height.
• GSZN Air Fryer Silicone — biggest strength: four food-grade silicone bumpers rated to 430°F/221°C that install on the air fryer tray to keep the interior from getting scratched. In my opinion it's the smarter pick if your Ultrean 9QT is already in daily use and you want to keep the nonstick surface intact.
• GSZN Air Fryer Silicone — biggest trade-off: it's built specifically for Ultrean 9QT air fryers, so it's the wrong purchase for almost any other brand or size.
• Who each pick is for: LU2000 → anyone with a cone-shaped egg-style air fryer, Instant Pot or pressure cooker that needs dust and vapor protection between uses. GSZN → Ultrean 9QT owners who want to protect the tray and interior from scratches.
The LU2000 Egg Shape Airfryer is a fabric dust cover, and that's the whole point. It's cut from 210D polyester with a lotus-leaf-style waterproof treatment on the outside and a silver lining on the inside, so it stands up to kitchen vapor, dust and lampblack rather than just sitting there looking decorative. It's machine washable too, which matters more than people expect — covers in a working kitchen get greasy, and being able to throw it in the wash instead of wiping it down is a real quality-of-life difference. It's also lightweight at roughly 0.03 kg, so it folds away flat when you're not using it.
Who should buy it: anyone whose air fryer, Instant Pot or pressure cooker lives on the counter and gets dusty, greasy or splattered between sessions, especially if pets or cooking vapor are a factor. The 90-day warranty is a modest but real safety net.
Who should skip it: if your appliance is a different shape or size, or you were hoping for a cooking accessory, this isn't it. Measure first — a loose cover on a non-cone appliance won't seal the way the drawstring design intends.
GSZN Air Fryer Silicone: Who It's For
The GSZN Air Fryer Silicone is a four-pack of silicone rubber bumpers, tabs or "feet" that sit on the air fryer tray. If you've ever pulled a tray out and heard that faint scrape against the interior wall, this is the fix. The bumpers are made from upgraded food-grade silicone — non-slip, scratch-resistant, tough enough that they're described as not easy to tear — and they're rated for temperatures up to 430°F/221°C, which puts them comfortably above typical air frying temperatures. That temperature ceiling is the spec that matters most here, because a silicone part that can't take the heat is worse than no part at all.
Installation is deliberately simple: you press them onto the tray, and they come off just as easily for cleaning. The whole point is protection — the bumpers act as a cushion between the tray and the air fryer's interior, so the metal doesn't grind against the coating every time you slide things in and out. Over months of daily cooking, that's the difference between an interior that still looks new and one that's covered in fine scratches.
The catch is compatibility, and it's a hard catch. These are made for the Ultrean 9QT air fryer specifically — the product name and the manufacturer's notes both say so. The dimensions are tiny (about 1 x 0.5 x 0.1 inches each, weighing 0.16 ounces for the set), so they're easy to lose if you're careless, and the listing notes a 1–3mm measurement tolerance.
Who should buy it: Ultrean 9QT owners who want to keep the tray and interior in good condition, and anyone who wants a cheap, low-effort way to reduce scratches and rattling.
Side-by-Side: Which Should You Choose?
• Best for protecting the outside of your appliance → LU2000 Egg Shape Airfryer. The full-wrap polyester with waterproof finish is built for dust, vapor and grease.
• Best for protecting the inside of your air fryer → GSZN Air Fryer Silicone. The bumpers cushion the tray against the interior walls.
• Best for Ultrean owners specifically → GSZN Air Fryer Silicone, but only if you own the 9QT model. Ultrean 4.2QT and 6QT owners should look at the LU2000 cover instead, which lists those sizes as compatible.
• Best for Instant Pot and pressure cooker owners → LU2000 Egg Shape Airfryer. It's sized for most 4–7 quart cone-shaped pots.
• Best if you hate cleaning grease off an appliance → LU2000 Egg Shape Airfryer. It's machine washable, so maintenance is a laundry cycle rather than scrubbing.
• Best if you want a part that never needs replacing mid-cook → GSZN Air Fryer Silicone. The 430°F/221°C rating covers normal air frying temperatures.
• Best for a low-commitment, easy-install upgrade → GSZN Air Fryer Silicone. Press on, pull off, done.
• Best if fit accuracy worries you → LU2000 Egg Shape Airfryer, thanks to the adjustable drawstring — but measure your appliance first either way.
If I had to pick one, I'd buy the LU2000 Egg Shape Airfryer — but only because it applies to far more people. In my opinion, a dust cover solves a problem almost every countertop air fryer or Instant Pot owner has, and the drawstring design plus the broad compatibility list makes it genuinely useful rather than fussy. The GSZN Air Fryer Silicone is the better product for a narrower job: if you own an Ultrean 9QT and want to keep the tray and interior scratch-free, that's the one I'd recommend, and the food-grade silicone and 430°F rating are exactly what you want to see. Check the current price on Amazon before you commit, and confirm your appliance model first — neither of these is a universal fit.
how to use ultrean air fryer
Load food into the basket, set your time and temperature, and let it run — the GSZN silicone bumpers install on the tray before cooking and stay there. They're rated to 430°F/221°C, so they're fine at normal air frying temperatures. Always check your Ultrean model's own manual for its specific settings.
how to preheat ultrean air fryer
Most air fryer owners preheat by running the empty basket for a few minutes at the cooking temperature. If you've fitted the GSZN silicone bumpers, leave them in place — their 430°F/221°C heat resistance is well above typical preheat temperatures. Follow your Ultrean model's instructions for exact timing.
how to clean ultrean air fryer
The GSZN bumpers are designed to be easy to install, disassemble and clean — pull them off the tray, wash them, and press them back on. They're non-slip and scratch-resistant food-grade silicone, so they tolerate normal washing. Clean the tray itself according to your Ultrean manual.
how to start ultrean air fryer
Plug it in, place your food on the tray (with the GSZN silicone bumpers fitted if you use them), then set time and temperature and start the cycle. The bumpers don't interfere with operation — they simply cushion the tray against the interior. Refer to your Ultrean model's manual for its specific controls.
