Fluff the down duvet up lightly every morning when making the bed to keep it fluffy. Store your down duvets clean, in a dry, spacious and well-ventilated place to keep the down fluffy.
Machine-wash the down duvet at 60 °C, use only one-third of the standard amount of liquid detergent. If you wish, you can choose a gentle special shampoo developed specifically for down products. Wool detergent is also suitable for down products. Remember to use an enzyme-free detergent that preserves the natural fat in the down and feathers.
Let the down duvet dry in a well-ventilated place and fluff it up while it dries. Tumble drying is an excellent way to make the down duvet more fluffy, and it significantly shortens drying time. Select a low heat setting for tumble drying. Place a couple of tennis balls in the tumble dryer, and stop the dryer from time to time and give the product a good shake before you continue drying. This keeps the filling fluffy and allows the duvet to dry evenly. Continue drying until the duvet is completely dry with a fresh smell.
