What Is Dust?

Answer 1

Dust in homes, offices, and other human environments is mainly generated by the inhabitants, and mainly from their skin cells that slough off. Some atmospheric dust from the outdoors is also present. On average, approximately 6 mg/m2/day of house dust is formed in private households, depending primarily on the amount of time spent at home. "Dust bunnies" are little clumps of fluff that form when sufficient dust accumulates.

The particles that make up house dust can easily become airborne, so care must be exercised when removing dust, as the activity intended to sanitize or remove dust may make it airborne. House dust can be removed by as many as ten methods listed hence: wiping, swiping or sweeping with a hand, a dust cloth, sponge, duster or a broom; or by suction from a vacuum cleaner or air filter. Dust is trapped by the device being used, however some becomes airborne and may come to settle in the cleaner's lungs, thus making the activity somewhat hazardous and slightly vain.

Answer 2

Dust can be fine particles of soot or lint from clothing or almost anything else, but what usually causes problems is the dust produced inside a house by dust mites. These microscopic beasties eat small particles of organic matter, usually skin cells too small for people to see. Then they excerete a gray-brown soft dust that clumps into just-visible lumps and clings to bedding and furniture. This substance is highly allergenic.

I was told by my doctor NEVER to do the vacuuming myself and to make sure that whoever did used a HEPA filter on the vacuum cleaner. I also had to get rid of most rugs and use a mite-proof covering on my pillow and mattress. Even with all that, I have to take Allegra or Claritin every day.

Answer 3

Micro particles from the environment. These can include remnants of pollen, dirt, fabric, animal dander, and tiny microbes called dust mites. Dust can live very well in your home - in your mattress, in carpets, heat ducts, etc. and tends to settle under just about anything. Dust can be a problem for people with alergies, especially in winter when you are indoors most of the time and the furnace is on. -A good time to vacuum.
