How to wash a down comforter: your washer will do. Cold, gentle, extra rinse, then low heat until the middle is dry.
Cloud Heaven Duvet
The duvet just needs room to move and no post in the middle of the drum. Use a little mild down wash and skip bleach, fabric softener and high heat. Water does the cleaning. Patience does the rest.
If putting something you saved up for into a washer makes your stomach drop, Wirecutter would understand: it ranks down comforters among the most intimidating bedding to wash, and more than one commenter under washing videos admits to being scared of it too. The fear is aimed at the wrong half, though. Washing is the easy part. Drying a down comforter all the way through is the real job, and it is where nearly every bad wash day goes wrong.

Can you wash a down comforter in the washing machine?
Yes, in a front loader, or a top loader with no post in the middle. That post is the agitator, and it is the one machine part worth worrying about.
St Genève's down product manager gives two reasons in their washing video: the agitator can damage the inside of a duvet, and a duvet pushed down into a top loader tends to float, so very little soap and water get through. People in the comments describe what a tight or uneven load does: half a queen comforter still bone dry when the cycle ends, and a washer that threw a balance error.
A front loader tumbles the duvet through the water instead. A top loader with a flat base and no post is the other choice: Feathered Friends allows one, though St Genève prefers a front loader. If yours has a post, this is a laundromat day, and that is not a defeat. A big front loader and a big dryer make the whole job easier. One commenter swapped a $65 dry cleaning bill for about $3 in a laundromat washer.
What size washer do you need for a down comforter?
One the duvet can turn over in, and no honest number fits every machine and every duvet. Two appliance makers publish a rule of thumb, and they are worth knowing:
- Whirlpool: the comforter should take up no more than three quarters of the washer.
- Maytag: washers of at least 5.0 cu ft are generally equipped for larger loads.
Our own duvet care guide puts it plainly: each piece needs room to move freely, and if the duvet crowds your machine, use a larger washer and dryer. We do not give a drum size for our duvets, because your own machine can tell you more than any number on a page.
Here is how to ask it. Before anything gets wet, put the dry duvet in your dryer, fully fluffed, and run it for a minute with no heat. If it rolls and falls, you are set. If it sits pressed against the drum, it will do worse wet, heavy with water. St Genève and Feathered Friends both start with this check, and it is the single best habit in this whole guide.
"The biggest thing with the dryer is it has to be big."
Not sure about your machines? The wash day planner further down turns all of this into a go or laundromat answer.
How do you wash a down duvet, step by step?
Six stations, and only one of them takes real time. Read them once before you start, so nothing surprises you with a wet duvet in your arms.
- Take the cover off. It goes in its own load: cold, gentle, zipper closed. On the weeks you wash only the cover, a second PureFlow Duvet Cover means the bed is never bare. While the duvet is bare, look over its seams. On a Cloud Heaven Duvet or PureFlow Air Duvet, a chamber seam that has come loose is covered by the 5 year Loft Promise, so write to us before you wash.
- Treat spots first. Dab with a cloth, cold water and a drop of mild detergent, then blot. No scrubbing.
- Wash it alone, cold and gentle. Nothing else in the drum. Use a little mild down wash. Soap left behind weighs the down and keeps it from rising, so use less than feels right.
- Add an extra rinse. This is where the soap leaves. A spin after it means less water for the dryer to fight.
- Lift it out, then dry on low. Wet down is heavy. Gather the duvet into a bundle and carry it from underneath, never by a corner, so its weight does not pull at the inside. Then straight into the dryer, on low.
- Cover back on, only when it is completely dry. Not almost. The next two sections are about exactly that. Our guide to putting on a duvet cover makes the last step quick.
How do you dry a down comforter?
On low heat, with two or three clean dryer balls, stopping every 30 minutes to shake it out, until the middle is dry. That is the whole method. The rest of this section is how to stick to it when the afternoon gets long.
First, a warning so you do not panic: it will come out of the washer thin, heavy and lumpy, nothing like the duvet you put in. That is what wet down does. Heat, air and tumbling pull the clusters apart again, a little more every half hour. Drying is what brings the loft back; what fill power means explains why that loft matters.
Keep the heat low, the whole way
Our care guide says low, and we mean the whole time. High heat can damage the down for good. Low takes longer, and longer is the cheap part.
Some guides go hotter: Jack Sukalac, the down expert Wirecutter interviewed, dries on low or medium and suggests hot for the first 20 minutes only against dust mites, and Feathered Friends and St Genève use medium heat for at least part of it. We do not. One small mercy on a YumeFeel duvet: the PureFlow shell does not shed lint in your dryer or on your clothes, however long the run.
Stop every 30 minutes
Pause the dryer, take the duvet out and shake it from two corners. Find any clumps with your fingers and gently pull them apart. Then put it back a different way round, so the parts that felt damp are on the outside where the warm air reaches them first. St Genève suggests the same refold.
Dryer balls, not tennis balls
Two or three clean dryer balls lift the fill as it tumbles. Tennis balls are the internet's favourite shortcut, and top comments under Reviewed's washing video warn that tennis balls stained or dyed their comforters. No dryer balls at all? You can do without them, as Feathered Friends says. Just be thorough about pulling clumps apart at every stop.
How long does it take?
Longer than you expect, and nobody can honestly give you one number. Maytag says 2 to 3 hours, then air drying flat. Peacock Alley says 4 to 10 hours. St Genève counts three to four dryer cycles. One commenter needed almost 10 hours of machine drying. Your dryer, your duvet and how hard the washer spun all move the number.
So start in the morning. Never begin at nine at night with nothing else to sleep under.
Drying at a laundromat
Commercial dryers usually run on time you buy rather than on cycles. Choose the lowest heat, buy time in short blocks, and use the end of each block as your 30 minute stop. Bring the duvet home only once it is dry; a damp duvet in a bag in the car is the start of a smell.
Never on a line, a rail or a radiator
Wet down is heavy, and hanging it lets that weight pull at the inside. It also needs moving air to rise, so a duvet that dries hanging still comes out flat. St Genève and billerbeck both say no line, and billerbeck adds no radiator and no sun. One commenter who hand washed in a bathtub, tried the dryer, then finished on a clothes rack spent four or five days on it.
How do you know it is completely dry?
Not by touch alone. The shell dries first, and it can feel dry while the down in the middle is still damp. Feathered Friends warns about exactly this, and our care page says the same: touch alone cannot establish that the filling is dry throughout.
Here is the check we would trust:
- Pause and let it cool. Warm down hides damp. A few minutes out of the dryer makes the difference easier to feel, a point St Genève makes too.
- Check the centre and the corners. Press into the thickest parts and squeeze the down between your fingers. Any spot that feels cooler, heavier or lumpier than the rest goes back in.
- When in doubt, 30 more minutes. Extra time on low costs you nothing. A damp middle closed up in a cover can start to smell, and St Genève warns that damp clumps can mildew.
Then comes the reward for the long afternoon: a duvet that is dry right through, tall and fluffy again, ready for its cover and your bed.
If lumps stay after it is truly dry, our guide to comforter clumping after washing walks through the fix.
What ruins down in the wash?
Heat, chemicals and impatience. Here are the mistakes we found in the guides and in the comments under washing videos, each with its fix. A comment is one person's report, not a rule.
- High heat to hurry it. One commenter's comforter barely fit a 5.1 cu ft washer, then high heat in the dryer finished it off. Fix: low heat, more time.
- Bleach. Some guides still add it for yellowing. Fix: skip it. On Heaven and Air, damage caused by bleach, high heat or dry cleaning is not covered by the Loft Promise.
- Fabric softener and dryer sheets. Softener coats the down and weighs it down, as St Genève explains. Maytag even lists softener sheets as a supply. Fix: leave them out.
- A crowded drum or a post in the middle. Half the duvet stays dry, or the washer throws a balance error. Fix: the dry fit test, or a laundromat.
- Tennis balls. Reports of dye and stains on the comforter. Fix: clean dryer balls, or your hands.
- Calling it dry too early. One commenter's comforter was still damp after two full cycles. Another washed a used comforter warm, and it still smelled bad after a whole day in the dryer. Fix: cool it, check the middle, keep going on low.
- Washing the whole thing for one spot. Fix: dab the mark and leave the rest alone.
- Hanging it to dry. Fix: the dryer, on low.
- Putting it away damp, or in a vacuum bag. Fix: a cotton bag in a cool, dry closet, and no long stretches in a vacuum bag.
How often should you wash a down duvet?
Only when it needs it: after a spill, or when it no longer smells fresh. Keep it in its cover and wash the cover every week or two instead. The cover is the layer that meets you; the duvet inside stays clean for a long time, and every wash it skips is a long drying day you skip too.
Why does every guide say something different?
Because they are written for different products, different machines and sometimes different countries. Here is what the pages and videos we read say, next to what our care guide says for every YumeFeel duvet.
What you will read, and what our care guide says
| Setting | What you will read | Our care guide |
|---|---|---|
| Water | Cold or warm (St Genève), warm (Feathered Friends), hot on a heavy cycle (Fix It Now) | Cold, gentle |
| Dryer heat | Low or medium, hot for 20 minutes only against dust mites (Wirecutter's expert), medium (Feathered Friends), medium then low (St Genève) | Low, the whole time |
| Balls | Tennis balls (several videos, and optional in Maytag's list), dryer balls helpful but not required (Feathered Friends) | Two or three clean dryer balls |
| Bleach | Half a cup (VeroLinens), non chlorine for yellowing (Peacock Alley) | Never |
| Softener | Softener sheets as a supply (Maytag), never (St Genève) | Never |
| Line drying | Sun drying is excellent (Peacock Alley), never (St Genève, billerbeck) | Tumble dry low until completely dry |
| How often | A few times a year (Linens & Hutch), yearly or when dirty (Feathered Friends), every 3 to 5 years (Wirecutter) | Only when needed; the cover every week or two |
Where they disagree, we take the gentler side every time. Water and a good rinse clean down. Heat and chemicals are what do lasting harm.
Should you dry clean a down comforter?
No. Wash it in water. VeroLinens and Jack Sukalac of All About Down, interviewed by Wirecutter, both say to launder down rather than dry clean it, and the 5 year Loft Promise on Heaven and Air lists damage caused by dry cleaning among the things it does not cover. A cleaner who launders duvets in water is a different service, a distinction Peacock Alley makes too.
For a small mark, do not wash the whole duvet. Dab it with a cloth, cold water and a drop of mild detergent, then blot it dry. If your comforter is from another maker and its label says dry clean only, follow the label and ask that maker.

Wash day planner
Home or laundromat, decided before anything gets wet.
Room test first
A front loader works. With no drum size: three quarters full at most (Whirlpool), and it must turn freely.
Dryer: first run the dry duvet a minute with no heat. If it tumbles, dry at home. If it presses on the drum, use a laundromat.
No balls: pull the clumps apart by hand every 30 minutes.
- A post in a top loader: a laundromat front loader.
- Front or flat top loader: at home if it fills three quarters of the drum at most (Whirlpool). Under 5.0 cu ft (Maytag), test first.
- Dryer: the dry fit test first, or a laundromat dryer on low.
Always: low heat, a shake every 30 minutes, then check the centre and corners once it cools.
Questions people ask
Can you put a down feather comforter in the dryer?
Yes, and you should: a dryer on low is the right way to dry down. Use two or three clean dryer balls, stop every 30 minutes to shake it out, and keep going until the middle is dry. What the duvet should never meet is high heat.
What should I wash my down comforter with?
A mild down wash, and only a little. Down soaps sold for sleeping bags and jackets are made for this. St Genève's team uses Tide Free and says to avoid enzyme cleaners. Whatever you pick, add the extra rinse.
Can I wash a duvet with the cover on?
Take it off. The cover and the duvet want different loads, and the cover needs washing far more often. Wash the cover cold on gentle with the zipper closed, tumble dry it low, and skip the iron.
How do I wash a duvet insert?
Exactly like this. A duvet insert is the filled part that lives inside your cover, and if it is down, every step above is its routine. Unzip the cover and wash that on its own, then give the insert a big drum to itself: cold, gentle, a mild down wash and an extra rinse, then low heat until the middle is dry. Book the dryer before the washer, because drying is the long half of the day. The cover takes the everyday washes, so the insert only goes in when it truly needs it. Treat a premium down insert like the Cloud Heaven Duvet this way and it comes back up tall and airy, ready to disappear into again.
Why does my comforter smell after washing?
Almost always because it is still damp inside. Put it back in on low, stop every 30 minutes, and check the middle after it cools. Do not cover the smell with a spray or put it away until it is completely dry.
Will washing make a noisy duvet quieter?
Not reliably, and repeat washes are not the fix. Find which layer makes the sound first: why is my duvet noisy walks you through it in five steps.
Is washing a goose down comforter any different?
No. Down is down in the washer: cold, gentle, an extra rinse, low heat. One routine covers all three of our premium down duvets, the Cloud Heaven Duvet, the PureFlow Air Duvet and the Royal Goose Down Duvet. Royal, our rarest, is filled with Canadian Hutterite white goose down and takes the same wash; follow the care instructions that come with it.
Will washing make my duvet flat?
Not if it dries properly. It comes out of the washer flat, and the dryer is what brings the loft back. Give Heaven a shake when you make the bed and the down lifts right back up. If an older comforter stays flat, try our guide to making a comforter fluffy again.
Should I throw away an old down comforter?
Not just because it looks tired. A wash and a long, low dry often bring a lot back. If it stays flat or lumpy after that, our guide on how often to replace a comforter helps you decide. On Heaven and Air, the 5 year Loft Promise covers flattening that stays even after a normal refresh.
How do I store a down comforter?
Completely dry, in a cotton bag, in a cool, dry closet. No long stretches in a vacuum bag, which squashes the down, and never a plastic bag over anything still damp.
How this was put together: on 13 Nov 2026 we read five ranking guides (Linens & Hutch, Wirecutter, Whirlpool, Maytag, Peacock Alley), watched nine washing videos and read their top comments, including VeroLinens, Reviewed, homesteady and Fix It Now. Comments are single reports, not a survey. Every setting we recommend is from the YumeFeel duvet care guide. We have not run our own washing trials. YumeFeel is our own brand.
