Seal the duvet you already own. From £79
2. Anti Allergy Duvet
New duvet, eucalyptus silk. From £119

If your duvet is fairly new and you like it, seal it. The Duvet Protector zips fully around it, seals in any mites already there and stops new ones getting in. Your normal duvet cover goes on top.
If your duvet is more than two years old, replace it. It is already full of mites and allergen. Start fresh with the Anti Allergy Duvet. If you run hot or have eczema, eucalyptus stays drier and feels cool on irritated skin.
If budget matters most, the Anti Allergy Cotton Duvet gives you the same tight shell and 60°C washing from £89.
A duvet sits on you for eight hours a night and collects skin flakes and moisture, which is exactly what dust mites feed and breed on. Within a year or two an ordinary duvet can hold thousands of mites. Swapping feathers for polyester does not change that. What matters is whether mites can get into the duvet, and whether you can kill any that do: a tight weave, 60°C washing, and no chemical coatings that wash out.
The mattress holds the most dust mites in your bed, and the pillow is where you breathe all night. If your symptoms are worst at night or first thing in the morning, sealing all three makes the biggest difference. The Protector Set seals your mattress, pillows and duvet in one order.
Not always. "Hypoallergenic" usually only means no feathers. An anti allergy duvet should also stop dust mites getting into the filling and be washable at 60°C. Ours do both.
9 tog suits most UK bedrooms all year round. If you sleep hot, the eucalyptus duvet feels cooler than its tog suggests.
Every 1 to 3 months at 60°C, and wash your duvet cover weekly at 60°C. Dry it fully before putting it back on the bed.
Single and Double fit most 8kg machines. For King and Super King, a 9kg+ drum or a launderette works best.
