Air fluff is a setting on a dryer that uses room temperature air to dry clothes without heat. This setting is also known as the "air dry" or "air only" cycle. It is useful for removing dust and fluff from clothes that have lost their volume from hanging in the closet or lying folded in a drawer. Air fluffing can also help to remove wrinkles from clothes. Since the dryer doesnt produce any heat for this setting, it is best used for items that are already dry. Air drying is the perfect setting for blankets to restore new life if they have been flattened from constant use around your house or apartment. Air fluff is also useful for fabric preservation and delicate garments. To use the air fluff setting, select the "air dry" or "air fluff" option on the dryer's control panel.
