What is dust and how can we reduce the amount of dust indoors?

Dust can be carried indoors. Pollen in the air can be sucked indoors through HVAC systems or carried inside by sticking to our clothing, skin or hair. Dust can also be tracked indoors on shoes.

Indoors, dust can accumulate from carpet and furniture fibers, from our own skin and of course pet hair. According to a 2009 study published in Environmental Science and Technology, about one third of dust comes from inorganic sources like carpet fiber and two thirds comes in from outdoor sources.

Dust presents a human health problem because it can cause respiratory problems, eye irritation, and prolong the lengths of colds and other viruses. Mini-blinds, electronics, horizontal surfaces like tops of cabinets and book shelves, lighting fixtures and upholstery are all dust magnets.

While dust cannot be eliminated entirely from most indoor settings it can be greatly reduced with minimal planning and a dedicated effort. Door mats that are large enough to whisk contaminates off of shoe soles are a critical line of defense. Mats should be placed on both sides of doorways. A regular vacuuming program for both floors and upholstered furniture is essential in reducing dust volume and improving indoor air quality. Finally, dusting horizontal surfaces, window blinds, and electronics with a dry microfiber dusting device rounds out an efficient dust reduction program.

The time of the year can affect the amount of dust in the environment and therefore the frequency with which tasks must be carried out. The pollen season started last week in Central Virginia and will require increased up efforts. In the winter months the amount of contaminant falls with the temperatures, allowing us to dial down dusting frequency.
