Why the answer varies by model
Air fryers move high-temperature air through specific openings. A liner that is harmless in one basket may cover critical holes in another. Manufacturers also differ: Philips currently advises against baking paper and tin foil for the Airfryer models covered by its support page. Follow the exact regional manual rather than a generic social-media tip.
| Material | Potential use when approved | Main risks |
|---|---|---|
| Aluminium foil | Containing drips around a small food item | Blocked airflow, contact with heater, reaction with acidic foods |
| Baking paper | Delicate or sticky foods; perforated liners | Lifting into heater, trapped moisture, blocked holes |
| Silicone liner | Reusable food-contact liner if sized and approved | Reduced airflow, added cleaning folds, heat-rating mismatch |
| Ovenproof dish | Saucy or baked foods when it fits the basket | Poor clearance, unsuitable material, reduced circulation |
Five checks before using any liner
- Read the exact model manual and manufacturer support page.
- Confirm the material’s heat rating and food-contact suitability.
- Keep the basket’s required airflow openings exposed.
- Make the liner smaller than the basket where instructions require clearance.
- Place enough food on top so paper or foil cannot lift.
Never preheat with loose paper or foil
An empty lightweight liner can be pulled upward by the fan and reach the heating element. Add it only with food and only when approved. Foil should be secured by the food and kept well away from the heater.
Do not line the appliance body or bottom pan automatically
The lower pan may collect grease and form part of the airflow path. Covering it can change cooking and heat behaviour. A basket liner does not grant permission to cover other surfaces.
Foods and situations requiring extra caution
- Highly acidic foods such as tomato or citrus can react with aluminium foil; use suitable cookware or paper if the model permits.
- Very fatty food can release hot grease; a liner may pool it rather than letting it drain.
- Wet batter and sauces can obstruct perforations and may need an ovenproof dish instead.
- Large liners that curl up the walls can interfere with circulation.
Can liners make food less crispy?
Yes. Solid liners can reduce airflow below the food and trap steam or fat. If the result is soft, test a smaller approved perforated liner or cook directly on the clean crisper plate.
See the crispy-food troubleshooting guide for loading, moisture, shaking and temperature checks.
Cleaning trade-off
A liner may catch some drips, but it does not keep the basket, crisper plate or chamber clean. Grease vapour and crumbs still travel. Remove residue after cooking so it does not smoke or bake onto the coating.

UAE buying checks for accessories
Verify that replacement liners, racks or dishes match the exact model—not only the advertised litre capacity. Imported accessories may use dimensions for a different regional basket. Check width, depth, height and heat rating.
Final recommendation
Direct basket cooking usually preserves airflow best. Use foil, paper or silicone only for a clear reason, only when approved, and only in a size and position that cannot move or obstruct the machine.
