How to wash your down duvet

Feather-light, fluffy and just generally wonderful. To ensure your down duvet to stay that way, you need to wash it properly. Putting tennis balls in the washing machine and using surfactant-free detergents are two good care tricks - but there are many more.


A quality down duvet keeps you warm and cosy when it's cold, and nice and cool when it's hot. Plus, you get that soft and fluffy feeling.

Mille Notti's Natura down duvet is filled with white, first-class goose down from Europe. Its 90% goose down and 10% goose feather make it truly luxurious and feather light.

- Also, you can tuck yourself in with a clear conscience, because all of our down products are audited by IDFL (International Down and Feather Testing Laboratory) to guarantee that there has been no live plucking of down and there has been no force feeding in the breeding of the birds. “Our down is manufactured in Poland, in a small factory with careful controls of both quality and the supply chain,” says Grete Edvardsen, at Mille Notti.


Here’s Grete's advice:

  • Shake your duvet regularly to ensure that the down is evenly distributed, and the duvet retains its fluffiness and volume. Air it to keep it fresh.

  • Down wicks moisture away from the body as you sleep. So don’t cover your duvet with a blanket - or anything else for that matter - first thing in the morning. Make the bed later to give the moisture time to evaporate.

  • Wash the duvet as infrequently as possible, as the down deteriorates with each wash. For a proper clean, wash in a washing machine at 60 degrees, and consider programming an extra rinse.

  • Wash your duvets one by one. Don’t stuff the machine full.

  • Don’t use fabric softener.

  • Important - choose the right detergent. Use a soap-based detergent, as ordinary detergents contain surfactants that damage the down. They break down the natural oils in the down and the result is a flat, dull duvet that loses its fluffiness.
    We recommend Down Wash by Five Oceans.

  • Put some tennis balls in the washing machine to prevent the down from clumping together.

Drying is crucial. Down and feathers can withstand water, but you can damage the cover if you don’t dry it properly. It can become lumpy and, in some cases, mould can grow inside.

  • Never hang or air dry a duvet.

  • Always tumble dry on low heat with a few tennis balls.
    We recommend Dryer Balls by Five Oceans.

  • It is extremely important that the duvet dries completely. Pause the tumble dryer, take the duvet out, and shake it so that the contents are evenly distributed and dry better. Even when the cycle ends automatically and the duvet feels dry on the outside, it can still be damp on the inside, so smell and shake it, and if it smells like damp feathers or doesn’t feel completely dry, continue tumble drying it until it’s completely dry and fresh.

  • Expect it to take time for the duvet to dry completely.


  • Of the highest quality - they contain only Class 1 European down.

  • Allergy-friendly - they are recommended by the Asthma Allergy Nordic organisation, which means they’re made of durable, down-tight percale and only contain down that has been thoroughly washed.

  • Ethically produced - they’re certified by the IDFL (International Down and Feather Testing Laboratory) which guarantees that the down hasn’t been picked from live birds and that there’s been no forced feeding during the raising of the birds. All down products are manufactured in Europe.

  • Clean and chemical-free - they’re marked with STANDARD 100 by OEKO-TEX® which ensures that the products don’t contain any harmful substances and that they’re safe for both children and adults.
