Look for unbleached parchment paper with a food‑grade silicone coating, as it is BPA‑free, PFAS‑free and heat‑resistant up to 450°F. This combination offers non‑stick performance while keeping the food’s flavor pure. Silicone‑coated paper also resists oil and water, making cleanup easier.

Disposable liners are cheap, lightweight, and require no washing, but they generate waste and must be replaced frequently. Reusable silicone liners cost more upfront, last for hundreds of uses, and can tolerate higher temperatures (up to 464°F). Choose paper for occasional use or large gatherings, and silicone for everyday cooking and sustainability.

Square liners that measure about 8 inches at the bottom and 9.4 inches at the top (e.g., 8‑inch × 1.8‑inch height) fit the majority of 5‑8 qt baskets. Brands such as Vailnd, Ctizne, and HONYAO list compatibility with Ninja AF100/AF150, Cosori, and Instant Pot models, so verify the basket’s interior width before buying.

Yes, liners with a higher GSM (40‑42 gsm) are roughly 20‑30 % thicker than standard 35 gsm sheets, providing extra strength and less chance of tearing during high‑heat cooking. Thicker liners also maintain their shape better in the air‑flow, helping to contain oil and grease. Products like HONYAO and Instant Pot’s 42 gsm liners highlight this benefit.

Most parchment paper liners are versatile and can be used in ovens, microwaves, toaster ovens, and even as serving plates. Silicone liners work well in ovens and as baking mats, offering a reusable alternative across several cooking methods. Check each product’s description for specific multi‑use claims.

Never pre‑heat an empty air fryer with a liner inside; the paper can scorch or the silicone can melt if it contacts the heating element directly. Always place food on the liner before turning the appliance on, and ensure the liner does not block airflow. Following the manufacturer’s safety tips prolongs both the liner’s life and your fryer’s performance.

Larger packs (e.g., 400‑piece or 200‑piece bundles) lower the cost per liner and are ideal for frequent cooks or large families. While bulk paper liners are inexpensive, they still provide the same non‑stick, heat‑resistant qualities as smaller packs. Reusable silicone sets may have a higher upfront price but save money over time by eliminating repeat purchases.

Paper liners made from unbleached, biodegradable wood pulp (such as Ctizne and HONYAO) break down naturally after use, reducing landfill impact. Reusable silicone liners are also environmentally friendly because they replace thousands of disposable sheets. Choose products that highlight BPA‑free, PFAS‑free, and compostable claims for the greenest choice.
