Curtains attract more dust, try washable blinds if able.
Laminate floors gather less dust than carpets and can be easier for damp dust cleaning.
Avoid lower bunk beds as dust constantly falls on top of person in the bottom bunk. The dust includes dead skin cells which we all shed daily.
Fabric covered furniture and cushions in your living room can also be a source of dust mites. If your child is unwell resting or sleeping on this kind of furniture is not a good idea.
