Yes — most duvets can be washed in a washing machine. Synthetic and hollowfibre duvets wash at 40°C in a large-drum machine; feather and down need more care and a bigger drum. The key limits are drum size (a king duvet needs 9kg+) and always drying thoroughly before re-use.
Most duvets can go in a domestic machine if it's big enough. Follow these steps:
Fill type decides the temperature, the care needed and how long drying takes.
| Fill type | Wash | Drying & notes |
|---|---|---|
| Hollowfibre / synthetic | 40°C, home machine fine | Tumble dry low — easiest of all fills |
| Feather | 30–40°C gentle, 9kg+ drum | Dry thoroughly with dryer balls; expect hours |
| Down | As feather but even gentler | Professional / launderette is often safer |
| Wool | Wool cycle or professional only | Always check the label first |
Feather and down specifics: wet feathers clump together. Dry them in a large dryer on low heat with a couple of tennis balls or dryer balls, and break up any clumps by hand every 30 minutes. A feather duvet that's only damp-dried will develop mildew, so don't rush this stage.
The single biggest factor is whether the duvet actually fits your machine with room to move.
| Duvet size | Minimum drum |
|---|---|
| Single | 7kg |
| Double | 8kg |
| King | 9kg |
| Super King | 10kg+ / launderette |
If the duvet has to be forced in, it won't wash or rinse properly — a launderette's large machine costs a few pounds and does the job right.
Yes for most synthetics on a low heat. Feather and down can also be tumbled on low with dryer balls, but plan for several cycles rather than one. To air-dry, lay the duvet flat over an airer or across two washing lines, turn it regularly, and allow a full day minimum. Never store or use a duvet that isn't bone dry — trapped moisture causes musty smells and mildew inside the fill.
Every 3–6 months is plenty if you use a washable protector and change the duvet cover weekly. Wash more often if anyone in the home has allergies: 60°C kills dust mites where the care label allows it (see Allergy UK for guidance).
Honestly, a duvet cover plus regular cover washing means the duvet itself needs far fewer full washes — the cover takes the day-to-day contact, so the duvet stays cleaner for longer.
No machine big enough? You still have options:
A single duvet, yes. A double is borderline and may not rinse well. A king and above need a 9kg+ drum or a launderette machine.
60°C — but only if the care label allows it. If it doesn't, wash the protector and cover at 60°C instead, which handles most of the exposure.
Yes, with a 9kg+ drum and a gentle cycle. Thorough drying is the critical part, so many people prefer a launderette's large dryers to get feathers fully dry.
Tumble dry on low with dryer balls, or maximise airflow when air-drying — laid flat over two lines outdoors beats a radiator, which only dries the outer layer.
It wasn't fully dry inside. Re-dry it completely; with feather fills, expect several hours of drying before the core is dry.
Only if the label says so — solvents can strip some fills. Most synthetic duvets prefer washing over dry cleaning.
