The HuHu fry and grill pan set utilizes an innovative design to reduce smoke, odor, and harmful pollutants when cooking. The pan features a patented inlet and outlet system that leads the pollutants to the heat source where it is burned away. The silicone seal on the lid prevents smoke from escaping and forces it to go down the inlet hole. The pans are made of die casted aluminum coated with non-stick Megastone coating giving it durability, corrosion resistance, and evenly distributed heat. Also, the grill pan comes with a furrow on the edges that separate grease and liquid from the food. Enjoy cooking healthier with our eco-friendly pan set. Odorless, Smokeless, Non-Stick, PFOA Free.
