Dust mites are everywhere. Not in your bed in particular, in every bed. Which comes down to this: you cannot eliminate dust mites, but you can manage them.
What they need
What dust mites need to live: warmth, moisture, and skin flakes. What they cannot bear: dryness, light, and high temperatures.
What you do.
Wash fitted sheet and duvet cover at sixty degrees, every two weeks. At sixty degrees dust mites die.
Air the bedroom every morning. Let the window stand open at least half an hour before you make the bed. Moisture and warmth leave the room.
Keep the bedroom cool. Between sixteen and eighteen degrees at night. Dust mites multiply less well in cooler air.
A down duvet
A down duvet is no attractive place for dust mites. The tight casing keeps them out, and a regular wash in our atelier dispels what might settle on the surface.
Strong reactions
Whoever has strong allergic reactions may choose anti-allergic covers around the mattress and the pillow. Combine that with good care, and the bedroom becomes a place where you can sleep, not a place you leave in the morning with irritated eyes.
