Are Air Fryer Liners Safe?
Reviewed by the RecipeAirFryer editorial team · Updated
Perforated paper and perforated silicone liners are safe and useful. Solid liners that cover the whole basket base are the problem - not because they are toxic, but because they block the airflow that makes an air fryer work.
Quick answer
- 1Choose perforated liners so air still reaches the underside of the food.
- 2Always put food on top of the liner before the basket goes in.
- 3Never preheat with an empty liner in the basket - the fan will lift it into the element.
- 4Keep paper liners below their rated temperature (usually around 220°C / 428°F).
Perforated: fine. Solid: defeats the point
A perforated liner lets the fast-moving air pass through to the base of the food, so you keep the all-round crisping. A solid liner seals the holes in the basket and turns it into a small, weak oven - bases come out pale and steamed.
This is the whole decision. If a liner has holes in it and food sits on top, it is doing no harm.
The one real hazard
A loose, unweighted liner is the genuine risk. The element sits just above the basket, and the fan can lift a bare paper or light silicone sheet straight up onto it, where it scorches or burns.
Weigh it down with food every time, and never run a preheat or an empty cycle with a liner sitting in the basket on its own.
Frequently Asked Questions
Are disposable paper air fryer liners safe?+
Yes, if they are perforated, kept under their rated temperature and always weighed down with food. Do not preheat with an empty sheet inside.
Are silicone air fryer liners any good?+
Perforated ones are fine and reusable. Solid silicone liners block airflow to the underside of the food, so bases come out pale - avoid those.
Can air fryer liners catch fire?+
Only if used wrongly. A loose liner can be lifted onto the element by the fan. Keep food on top of it and never run the fryer empty with a liner in the basket.
