The duvet is the 9 tog inner that keeps you warm, made with a tested 40 micron weave that dust mites cannot settle inside. The duvet protector is a 5 micron fully zip sealed encasement that goes around a duvet and blocks 100% of dust mites. Together they are the strongest option: built in corner loops tie this duvet flat inside our protector, and you only wash the protector every one to three months instead of washing a whole duvet weekly.

Your duvet sits inches from your face for eight hours a night. An ordinary duvet fills with skin cells and moisture, which is exactly what dust mites need to live and breed. This duvet keeps them out with its tested 40 micron weave and stays too dry for them to settle, so there is far less allergen against your skin and in the air you breathe. Most customers notice calmer skin and clearer mornings within the first couple of weeks.

Yes. There are no chemical treatments and everything is OEKO-TEX certified, suitable for children with eczema or asthma. We make a Cot Bed size at 120cm x 150cm, and because it washes at 60°C, the temperature that kills dust mites, it stays properly hygienic through years of use.

For milder symptoms, replacing an old duvet with this one and washing your bedding at 60°C weekly makes a real difference on its own. For moderate to severe allergies, pair it with our 5 micron protectors: this duvet stops mites settling in the duvet itself, while the protectors block 100% of the mites already living inside your mattress and pillows. That combination is what Richard recommends on the phone every day.

No chemicals at all. The protection is woven in: a tested 40 micron eucalyptus silk weave too tight for skin cells to fall through, so dust mites have nothing to feed on inside. Eucalyptus also dries far faster than cotton, and dust mites cannot breed in a dry duvet. Because nothing is sprayed on, nothing washes out. For a 100% sealed barrier, add the 5 micron duvet protector around it. OEKO-TEX certified throughout.

The outer is 1,000 thread count eucalyptus silk: cool, soft and completely silent, with none of the crinkle or plasticky feel of cheap anti allergy bedding. At 9 tog with a light anti allergy hollowfibre filling, it is right for year round use in UK homes.

Less exposure starts from the very first night under it. Most people notice calmer skin and less congestion within one to two weeks, with a clearer improvement by the end of the first month.

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.
