How it works
Anti dust mite cotton duvet with hypoallergenic anti allergy hollowfibre filling. 9 tog, suitable for year round use in UK homes, machine washable at 60°C, the temperature that kills dust mites.
Dust mites build up in duvets that cannot take a hot wash. Most ordinary duvets wash at 30°C or 40°C, which dust mites survive. This duvet is built to sustain a weekly 60°C wash without losing its softness, so anything that settles in it gets killed rather than left to accumulate. The breathable cotton outer lets heat and moisture escape and the hollowfibre core stays light, soft and lofty.
Built in corner ties attach inside our Anti Dust Mite Duvet Protector, so the duvet stays flat and never bunches or slides inside it.
Want the strongest anti dust mite duvet we make? Our Anti Dust Mite Eucalyptus Silk Duvet adds two things this cotton duvet does not have: a tested 40 micron barrier weave that stops skin cells getting inside, so dust mites cannot settle in the duvet at all, and eucalyptus fibre that draws moisture away far faster than cotton, keeping the duvet too dry for dust mites to breed in. It is the duvet most of our allergy customers choose.
Sizes: cot bed 120cm x 150cm, single 135cm x 200cm, double 200cm x 200cm, king 225cm x 220cm, super king 260cm x 220cm. These are standard UK duvet sizes, so your existing duvet covers fit perfectly.
Care: wash weekly at 60°C when used on its own, or place it inside our Anti Dust Mite Duvet Protector and wash the protector every one to three months instead. Tumble dry low or line dry.

Stop The Itch
Your duvet is one of the biggest dust mite reservoirs in the bed, and it touches your skin all night. This cotton duvet washes at 60°C so you can clear the mites out every week. For skin that reacts to everything, the Eucalyptus Silk upgrade adds a tested 40 micron weave that keeps mites out between washes.

Nighttime Allergy Relief
Ordinary duvets are never hot washed, so they fill with mites over years. This one takes a 60°C wash week after week. Add the 5 micron duvet protector around it and anything already inside is sealed away for good, or upgrade to Eucalyptus Silk so the duvet itself keeps mites out.

Breathe Easy At Night
You breathe whatever sits inches from your face for eight hours a night. A duvet you can hot wash weekly, with sealed protectors on the mattress and pillows underneath, means far less allergen in the air you breathe all night.

No Morning Congestion
Waking blocked up is the classic sign of a mite-heavy bed. Swap an old, never-washed duvet for one you hot wash every week, seal the mattress and pillows, and most people wake clearer within the first couple of weeks.

Everything you need to know about dust mite protection.
The cotton duvet is the 9 tog inner that keeps you warm, and it washes at 60°C so it never builds up mites. The duvet protector is a 5 micron fully zip sealed encasement that goes around any duvet and blocks 100% of dust mites. If you want the inner itself to resist mites, our Eucalyptus Silk duvet adds a tested 40 micron weave, and paired with the protector it is the strongest option.
Your duvet sits inches from your face for eight hours a night, and an old duvet that has never had a hot wash is full of dust mites. This cotton duvet washes at 60°C, the temperature that kills them, so the layer over you stays clean. For itchy skin, congestion and night-time wheezing the bigger wins come from sealing the mattress and pillows with our protectors, and from choosing the Eucalyptus Silk duvet, whose tested 40 micron weave keeps mites out between washes.
Yes. It is hypoallergenic 9 tog cotton in a Cot Bed size of 120cm x 150cm, and because it washes at 60°C it stays properly hygienic through years of use. For a child who scratches at night, pair it with our pillow and mattress protectors, and if eczema is severe choose the Eucalyptus Silk duvet instead: its tested barrier weave keeps skin cells out so mites have nothing to feed on.
For milder symptoms, replacing an old duvet with this one and washing it at 60°C weekly makes a real difference. On its own no duvet solves a dust mite allergy, because most of the mites live in the mattress. If you only buy one thing, buy the mattress protector. If you want the duvet itself to do more of the work between washes, upgrade to the Eucalyptus Silk, then pair either duvet with our 5 micron protectors, which block 100% of the mites already in your bed. That combination is what Richard recommends on the phone every day.
This cotton duvet resists dust mites the simple way: a 60°C wash kills them and removes the allergen they leave behind, and this duvet is built to take that wash every week. Cotton has no barrier weave, so between washes mites can settle inside like any ordinary duvet. If you want a duvet that keeps them out all the time, choose the Eucalyptus Silk: a tested 40 micron weave too tight for skin cells to fall through, moisture wicking so it stays too dry for mites to breed, and no chemical treatments.
A classic cotton duvet: soft, breathable and warm, with a light anti allergy hollowfibre filling at 9 tog for year round use in UK homes. Corner ties keep it flat inside your cover. The Eucalyptus Silk feels cooler and silkier against the skin and wicks sweat away, which is why hot sleepers and eczema sufferers usually prefer it.
Most people notice a difference within the first week of switching from an old duvet to a freshly hot washed one, especially if the old one had never seen a 60°C wash. Keep washing weekly and pair it with sealed protectors on the mattress and pillows and the improvement holds.
On its own, wash it at 60°C, the temperature that kills dust mites, then tumble dry low or line dry. Inside our duvet protector, you only wash the protector every one to three months and the duvet needs washing far less often. Worth knowing: king and super king duvets are heavy for standard 7 to 8kg machines, which is another reason most customers choose the protector.
