Answer 2

House dust is not dust that blows in from the outside. House dust is produced indoors from several sources:
The breakdown and release of plant and animal materials used in the home. These contaminants include such items as feathers, cotton, wool, jute, hemp, and animal hairs. They come from clothing, carpets, rugs and furniture.
The disintegrated stuffing material from mattresses, pillows, quilts, and upholstered furniture. Prolonged use seems to cause these resilient fibers to weaken and eventually break down into particles small enough to be inhaled.
Human skin scales, animal dander, insect parts from cockroaches and dust mites, saliva, molds and mildew, bacteria, viruses, and pollen. As people go through their daily activities, particles that have settled onto the floor and other surfaces are stirred into the air.
Other contaminants deliberately introduced into the indoor environment. These can include tobacco smoke from pipes, cigars and cigarettes, cosmetic powders, baby powder and some powdered laundry detergents, aerosols such as air fresheners, and cleaning products with strong odors.
Of cause if you have large infiltration of the outside air you will also get outdoor dust which will contain large quantities of the earth particles and biological components like polens molds etc.
