Although there is no strong evidence that reducing dust and dust mites in your home will reduce symptoms of asthma or allergic reactions, the following steps may be helpful.
Dust mites are visible only through a microscope. People are allergic to dust mite droppings, not the dust mites themselves. Allergy to dust mites is a year-round problem.
Adults spend one-third of their time and children spend half of their time in their bedrooms, so it is important that you take steps to prevent allergens in this room.
