What is air fluff on dryer?

Air fluff on a dryer is a setting that uses only room temperature air to fluff and freshen up clothing and other items without applying heat. This setting is useful for delicate items that may be damaged or shrink when exposed to heat, such as certain fabrics or embellishments. It can also be used to remove wrinkles from clothing that has been sitting in the dryer for a long time or to help dry items that are already mostly dry but just need a bit of fluffing. The air fluff setting is typically used for short cycles, as it does not actually dry the items but rather helps to freshen them up or remove wrinkles.
