Bedding for people whose allergy is dust mites

What is the best bedding for a dust mite allergy?

A wool comforter and a wool pillow, a waterproof protector under the pillowcase, and cotton sheets and covers you wash every week. Your nose is worst in bed because the bed is where the shed skin is, and what the mites need on top of it is humidity.

The short answer

A wool duvet and a wool pillow, a waterproof protector under the pillowcase, and cotton sheets and covers you wash weekly. Dust mites cannot drink. They pull water out of the air around them, and they need it above roughly 50 percent humidity to hold their balance. Wool moves moisture off your skin and into the fiber, so the air under the duvet and around your head stays drier than that, with nothing sprayed on and nothing to wear off. The washable layers handle the rest, because a warm weekly wash removes the skin the mites feed on and the allergen they leave behind. None of this treats an allergy. It takes the load out of the one place you breathe for eight hours.

The short version, in five lines

  • Dust mites feed on the flakes of skin people shed, and a bed collects more of that than anywhere else in the house, which is not something you get to change.
  • What you can change is the humidity. The Asthma and Allergy Foundation of America puts what dust mites like at above 50 percent, and tells you to keep a home between 30 and 50.
  • Wool moves moisture off your skin and into the fiber, so the air under the duvet and around your head sits drier than the air in the room. Nothing is sprayed on and there is nothing to wash out.
  • The washable layers do the other half. A weekly wash takes away the skin and the allergen that comes with it, and a waterproof protector keeps the pillow itself out of the weekly cycle.
  • None of this is a treatment for an allergy. It takes the load out of the one room you breathe in for eight hours, and if your symptoms are heavy you want an allergist as well.

Dry the air, wash the surfaces, and put a barrier under the pillowcase.

Three jobs, and each piece here does one of them. Nothing on this page has been treated with anything.

Morning sun on a dark wood bed. The Circadian Organic Wool Comforter, a hand-tufted duvet insert, lies thrown back, with the Handmade in the USA seal and the label of GOTS, the Global Organic Textile Standard (Organic, certified by OTCO, GOTS-10229).
Dry under the duvet

Organic Wool Comforter

Hand-tufted organic wool that takes moisture off your skin into the fiber, so the air under the duvet stays too dry for dust mites to settle in. It is the fiber doing this, so it lasts the life of the duvet.

Most night-time allergies are dust mites, and a bed is where they do best.

Dust mites feed on the dead skin every one of us sheds, and their droppings are what your body reacts to. Your face spends about eight hours a night pressed into the place where both collect.

1

You shed skin all night

Onto the pillow, the sheet and the inside of the duvet cover. That is the food supply, and a bed replenishes it every night.

2

You breathe out moisture all night

Mites cannot drink, so this is the water supply. In bedding that holds moisture in the air, the humidity around your face sits above the level they need.

3

Polyester gives them the best of both

In a published twelve-month study of pillows on the same beds, the synthetic pillows ended up holding about three times the dust mite allergen the feather pillows did.

4

And you wake up blocked

Because the highest concentration of the allergen in the house is the surface an inch from your nose.

Change what the bed offers them. Wool takes the moisture out of the air they need. A protector keeps the skin they feed on out of the pillow. A weekly wash removes what has built up on the surfaces. It is not a cure, and it changes the one place you spend eight hours.

Wool holds the air around you too dry for dust mites to settle in.

Dust mites have no way to drink. They absorb water from the air through their bodies, and to hold their balance they need the humidity around them above roughly 50 percent. Bedding decides what that number is at your face. A synthetic pillow or duvet holds the moisture you give off in the air against you, which is exactly the damp, warm pocket mites do well in.

Wool moves that moisture off the surface and into the fiber, up to 30 percent of its own weight before it feels damp. The air between you and the wool stays drier than mites can use. This is a property of the fiber. Nothing was sprayed on, so there is nothing to wash out, and the duvet and pillow do the same job in year ten as on night one.

A protector keeps the food supply out of the pillow.

Whatever the pillow is made of, skin and sweat go into it through the case unless something stops them. A pillow that has been fed for a few years is where the allergen builds up. Our protector zips all the way round the pillow. It is organic cotton on both faces with a bio-based waterproof layer sealed between them, so what you shed stays on the washable side, and it does not crinkle when you turn over.

In one published test, mites crossed a standard synthetic pillow ticking inside 24 hours, while a tighter weave was still holding them out at 48. A sealed protector under the pillowcase is the version of that idea you can wash. It is certified organic inside and out and GreenGuard Gold, and it comes in every size we make a pillow in.

Wash the layers that touch you every week, warm.

Sheets, pillowcases and the duvet cover are where the shed skin lands, and a warm weekly wash removes both the skin and the allergen that has built up on it. That is why everything here that touches you is organic cotton you can put in the machine, and why our duvets live inside a cover rather than being washed themselves. The cotton is undyed and unfinished, so there is no resin closing the weave and nothing added to react to.

The first National Survey of Lead and Allergens in Housing sampled dust from the beds of 831 American homes and found 46 percent of them at or above 2 micrograms of mite allergen per gram, which is the level researchers use as a sensitization benchmark. The bed is also the one place in the house where that load is easy to bring down. Wash weekly, keep a second pillowcase in rotation, and air the wool duvet and pillow in a dry spot a few times a year.

The Asthma and Allergy Foundation of America says dust mites like humidity above 50 percent, and tells you to keep a home between 30 and 50. It gives 130 degrees Fahrenheit or hotter as the weekly bedding wash. Our own care instruction for the sateen is a cold wash, because cotton takes more shrinkage at 130. Run whichever of the two matters more to you on the sheets and pillowcases. There is no antimicrobial spray or mite treatment on anything we make.

Where do you notice it.

Blocked nose first thing, every morning.

Start at the pillow. The wool pillow keeps the air at your face dry, and the protector under the case keeps the skin you shed out of it.

What the words in this category mean.

This is the corner of bedding with the loosest language in it, so here is ours.

Dust mite
A microscopic relative of the spider that lives in bedding and carpet. It does not bite and it does not drink; it takes the water it needs out of the air around it, which is why humidity is the lever.
Allergen
The protein people react to. With dust mites it comes from their waste and their remains, not the animal itself, which is why removing it is a laundry problem rather than a pest problem.
Encasement, or protector
A sealed cover that goes over the pillow or mattress and under the pillowcase, so the piece you cannot wash weekly stays out of the cycle. Ours has a bio-based waterproof film behind an organic cotton face.
Relative humidity
How much water the air is holding against how much it could hold at that temperature. Above about 50 percent is the range dust mites do well in, which is the AAFA's number.
Lanolin
The wax wool carries in its natural state, and the reason wool bedding is usually recommended to allergy sufferers. The mechanism this page stands on is the humidity one instead, because that is the one with a number behind it you can check.

The ones we hear most.

What is the best bedding for a dust mite allergy?

A wool duvet and a wool pillow, a sealed protector under the pillowcase, and cotton sheets and covers you wash warm every week. Dust mites need the humidity around them above roughly 50 percent, and wool moves moisture off your skin into the fiber so the air stays drier than that. The washable layers remove the skin they feed on and the allergen they leave behind.

Is a wool comforter better than a synthetic one for dust mite allergies?

For the humidity, yes. Ours is a duvet insert, so it goes inside a cover and clips at the corners, and the two words describe the same thing. Polyester holds the moisture you give off in the air against you, and humidity above about half is the range the Asthma and Allergy Foundation of America says dust mites like. Wool moves that moisture into the fiber instead, so the air between you and the bedding sits drier.

Is wool bedding good for dust mite allergies?

It is the fiber we point people to first. Dust mites cannot drink and take water from the air, and wool holds the air around you too dry for them to settle in. That comes from the fiber rather than from a spray, so it does not wash out. The wool sits inside an organic cotton cover, so the surface against you is cotton you can wash.

Is a wool duvet better than down for allergies?

Down absorbs moisture and holds it in the cluster, which keeps the air under the duvet damp, and damp is what mites need. Wool takes the moisture into the fiber and away from the air. Many people with a dust mite allergy also find feather and down bedding itself is a trigger, which is another reason to move away from it.

Do you treat the bedding against dust mites?

No. Nothing on this page has been sprayed with anything. An antimicrobial or anti-mite finish is a treatment that washes out over a year and gives you a claim with a shelf life. The way wool behaves is a property of the fiber, and it is the same in year ten.

How often should I wash bedding if I have a dust mite allergy?

Every week for the layers that touch you, which is the fitted sheet, the pillowcase and the duvet cover, in warm water. Keep two pillowcases in rotation. The wool duvet and pillow do not go in the machine, which is why they live inside washable cotton. A few hours in a dry spot, twice a year, keeps them fresh.

Do I still need a dust mite cover on the pillow?

A sealed protector still earns its place under the pillowcase, because it keeps skin oil and sweat out of the pillow entirely, and a pillow that never gets fed stays clean for years. Ours is organic cotton on both faces with a waterproof layer sealed between, zipped all the way round, and it does not crinkle.

Are organic cotton sheets good for allergies?

They are the right washable layer. Cotton takes moisture off the skin and goes through a wash every week without wearing out. Ours is undyed and unfinished, so no resin closes the weave and there is nothing added to react to. The certification limits every input in the cloth to a pre-approved list.

Will this bedding cure my allergy?

No, and we would rather say so. It lowers the load in the one place you breathe for eight hours, which is what most people notice in the mornings. It does not treat the allergy itself. If your symptoms are heavy, see an allergist, and use bedding as one part of what they suggest.

Is synthetic bedding worse for dust mites?

For the humidity, yes. Polyester holds the moisture you give off in the air against you, and humidity above about half is the range the AAFA says dust mites like. Wool moves that moisture into the fiber, so the air between you and the bedding sits drier. The other half of it is laundry: a pillow nobody can wash, under a case somebody washes weekly, is where the allergen collects.

What if it does not help?

Send it back inside 60 nights, and free shipping applies. Most people with a dust mite allergy know inside two or three weeks of washing weekly whether the mornings have changed.

“I have owned more pillows than I have owned houses and I have owned 12 houses.”  This is by far the only pillow to use if you don’t want to wake up with sore shoulders or neck. I have replaced all the pillows in my house with this pillow.

I have compressed discs in my neck, and I have spent hundreds of dollars over the past 6 months trying to find one that will help me sleep. Every pillow I bought caused me to wake up in even more pain than the night before!! The buckwheat pillow is life-changing!! I have slept through the night and wake up with no pain!!
Verified Patty Buckwheat Pillow · August 2026
I was leery to try another expensive pillow without some sort of trial period after being very let down by a different company's natural fiber pillow… I don't hear anything at all with the buckwheat! It does stay fresh and cool as well, but most importantly it actually holds my head/neck up and in place. Which allows me to actually get rest instead of always adjusting.
Verified Morgan Buckwheat Pillow · August 2026
I've been a buckwheat pillow customer for the last 7 years and I can say that Circadian has the highest standards of quality paired with incredible customer service. Very very impressed and would not hesitate to send anyone their way.
Verified Taylor Buckwheat Pillow · August 2026
I have spent years searching for a pillow that feels supportive and comfortable all night. I have finally found it. I absolutely love the Buckwool pillow. I removed a bit of the material to get it to exactly how I want it… I rarely wake up with neck pain now.
Verified Anonymous Buckwool Hybrid Pillow · August 2026
I find myself switching between the two and loving the feel of both. I haven't woken up with a sweaty head with either and that's an amazing feeling especially in the AZ summer. The buckwheat side is a lot quieter and more comfy/soft than others I've tried in the past.
Verified Ashley Buckwool Hybrid Pillow · August 2026
I have tried at least 10 different pillows in the last 3 years. Nothing has worked out except for this wool pillow. I have chronic neck pain which has been greatly reduced. I am very happy with my new pillow.
Verified Anonymous Organic Wool Pillow · August 2026
I have pretty bad chemical sensitivity (housebound most of the time)… I try to only buy totally safe, non-toxic products. I found this pillow to be very safe and non-toxic, and the packaging was fragrance free which is always a huge plus.
Verified Janie Wild-Harvested Kapok Pillow · August 2026
I ordered this pillow to replace my very old (but beloved) down pillow and I'm so glad I did. It is heavenly!… I advise you to heed the recommendation given by the quiz. I ordered cotton initially despite the quiz giving me kapok as a result… the quiz was right.
