11️⃣ Are Disposable Liners Safe for Ninja AF400? What UK Buyers Should Know
The Ninja Dual Zone AF400/AF400UK makes it easy to cook two foods at once, but baskets can get grimy fast after marinades, cheese, or fatty foods. Liners keep mess off the base so clean-up is quicker and less scrubbing-heavy.

Square vs round: why shape changes your results
In AF400-style square baskets, square liners usually sit flatter and catch more grease in the corners. Round liners can work for small batches, but may waste space and leave drippy corners uncovered.

Fit and airflow: corners, gaps, and crispiness
Crisping depends on airflow. Use liners like a tidy tray, keep portions in a single layer, and turn/shake halfway. If your liner is solid, rely on the crisper plate so air can reach underneath.

Oil pooling and clean-up differences
Paper is “use and bin”, while silicone is washable but can stain with spicy sauces. A quick rinse after cooking helps, and checking buyer feedback can hint at how easy each type is to clean.

Picking the right shape for your baskets
Square liners typically give better coverage in AF400 baskets, catching grease in the corners and reducing baked-on spots. Round liners can be fine for small portions, but they may leave exposed edges where drips can bake on.
Shape tips for square baskets
Quick wins:
• Add paper only when food goes in (no empty preheats).
• Keep edges down and avoid oversized liners with big folds.
• Turn/shake halfway so airflow stays strong.
• Want a quick pick? Check price on Amazon UK or go reusable with Check price on Amazon UK.
Mini buying checklist: match liner shape to basket shape. Square baskets usually prefer square liners for full corner coverage and less baked-on residue.
Safe-use reminder: match the liner’s shape to the basket so corners aren’t exposed. Better coverage means less baked-on residue and fewer smoky re-heats later.
Storage tip: keep paper liners flat and dry so rims stay crisp and don’t warp. A crushed rim is more likely to lift once the fan starts moving air around the basket.
Extra tip: if corners keep getting dirty, switch to a squarer liner shape. Corner coverage is a big part of why some liners feel “better”.

FAQ
Do square liners always fit better in AF400?
Often, yes, because the AF400 baskets are more square/rectangular. But always check exact dimensions.
Is round safer because it stays away from edges?
Not necessarily. If it’s too small, drips can escape and bake on. Proper fit is what matters.
Can I fold a round liner to fit?
Folding can create thick seams that block airflow. If you fold, keep it minimal and flat.
Which is best for baking in the air fryer?
A well-fitting paper liner can be great for quick bakes, but ensure it’s weighted and doesn’t lift.
