Mini oven’ types: these models use convection or fan technology to cook food on flat, slide-in trays. As well as roasting, their extra air-frying functions circulate hot air around the food for more efficient crisping. These took up the space of an average-sized microwave. Some may also include rotisserie elements. Basket style with heating elements: tall, slim air-fryers feature a main unit with heating elements and fans. These have slide-out baskets or trays that slot into place inside. As they tend to have a smaller cooking area than oven-style fryers, in testing we found even results were more likely if the cooking was paused occasionally to rearrange or toss the food around. Some fryers will cut out automatically when you do this, some will need to be paused if you want accurate timings.

Whether you want to upgrade to a newer model, or your air-fryer has reached the end of its life, knowing how and where to dispose of your appliance is important to avoid creating more e-waste.
